Curling up in front of a cozy fire is an appealing activity when cold winter weather strikes, and brick fireplaces add a certain charm to this scene. Fire brick has long been a popular material for fireplaces and chimneys due to its beauty, durability, and ability to withstand high temperatures. However, regular maintenance and repairs are key to maintaining these features and ensuring the safety of your fireplace and chimney.

What to use to repair brick mortar

Over time, exposure to heat, weather, and other environmental factors can cause brick mortar to fail. Using the appropriate materials when repairing brick mortar in fireplaces and chimneys is essential to preserving the integrity of these structures. 

Because the mortar in fireplaces is subjected to high temperatures, a special kind of mortar is needed to prevent it from crumbling away. Refractory mortar is the choice of masons because of its ability to withstand heat up to 2,000 degrees. This high-temperature fireplace mortar can be used on mortar joints and fire bricks and comes in a caulk tube, making application simple.

When the mortar in a fireplace or chimney is in need of repair, tuckpointing is a great method for stopping deterioration and promoting structural stability. Tuckpointing is a repair process that involves removing the damaged mortar, replacing it with mortar that is a close color match for the bricks, and then filling in the center of the mortar joints with a line of mortar in a contrasting color. It is of the utmost importance to repair failing mortar joints in chimneys because not doing so can result in a weak chimney that will lean and eventually collapse. 

Can you repair cracked fire bricks?

You absolutely can, and should, repair cracked fire bricks to safeguard against a potentially dangerous situation. Refractory mortar can be used to make minor fire brick repairs, but more significant damage can be fixed using brick cement repair. Fire cement is designed to be flexible and durable in conditions where temperatures fluctuate drastically so is the ideal choice for repairing fire bricks that have cracked or are otherwise damaged. After making the repairs, it is important to gradually increase the heat for four to six hours and then let the bricks cool completely. Wait another six hours before using your fireplace normally, in order to allow the cement to cure.

Repairing brick and mortar degradation in fireplaces and chimneys is imperative to the safety and stability of these structures, and while minor fixes can be handled by handy DIYers, it is wise to consider hiring a professional to fix these sensitive areas. Homeowners can rest easy knowing that the job has been done correctly and safely by someone with the proper materials and expertise.

How to Repair Crumbling Red Bricks

While brick gives any facade a charming appearance, it needs to be regularly maintained and repaired to prolong its life and beauty. Crumbling bricks are not only an eyesore, but they also can result in long-term damage and structural instability.

Brick repair

Brick can last for hundreds of years when properly cared for, but the mortar in between has a much shorter lifespan. When left untreated, cracked and crumbling mortar can allow moisture to seep into the bricks, which in turn causes bricks to break down as well. The longer the brick and mortar are allowed to remain in disrepair, the more deterioration will occur. Completing brick and mortar repairs promptly can save you a lot of money and headaches in the long run, so address decay when you see it. Repointing and tuckpointing are both great methods for repairing mortar and preventing further damage to your bricks. When brick is crumbling, the time and price both increases, as does the level of difficulty to complete the repairs. If the repairs are minimal, skilled DIYers might be able to complete the project on their own. However, bigger jobs or brick repairs needed on exterior, or load-bearing walls require more expertise, so search for “brick wall repair near me” to find a professional to safely get the job done.

How to repair crumbling red bricks

Whether you decide you can handle the repairs or want to hire a professional, repairing crumbling red bricks can be a time-consuming job. Understanding the steps involved is a good way to determine which is the best option for you.

  • Remove the crumbling bricks: The first step is to get rid of the damaged brick. However, if several bricks need to be replaced, only do a few at a time to avoid collapsing the wall. Drill small holes in the center of the brick then use a chisel and hammer to break the brick and mortar into small pieces. Remove the pieces, clean up dust and debris, and rinse the whole area with water.
  • Mix and apply the new mortar: Mix up the new mortar, making sure it is weaker than your brick and closely matches the color of the existing mortar. Use a pointing trowel to spread a 1 inch layer of mortar on the bottom of the recess along with the ends and top of the new brick. It can help to think of mortaring bricks like buttering toast.
  • Insert the new brick: Slide the replacement brick into the cavity using the pointing trowel then wiggle the brick around to ensure the mortar joints as even as possible. Use a straightedge to push the brick level with the wall.
  • Tool the joints: Once the mortar has hardened but is still slightly pliable, brush off the excess mortar then use a jointer tool to tool the joints so that they match the style of the existing joints.

 

How to Repair Brick Steps

Thanks to their charming, classic appearance, brick steps can really increase the curb appeal of your home. But like any other brick structure, they need to be cared for in order to keep them looking their best.

How to fix mortar in brick steps

If you find that the mortar between your brick steps is cracked and missing, you need to promptly repair them in order to prevent additional damage to the bricks or to the structural integrity of the steps. Mortar deteriorates naturally over time, but sometimes cracking and crumbling occurs when the wrong type of mortar was used or because the steps don’t have proper support. The way to go about repairing the mortar in brick steps can depend on what is causing the problems.

If the mortar between your brick steps is cracked and crumbling due to natural deterioration or because the wrong type of mortar was used, repointing is a great option to repair the joints. In repointing, the old mortar is removed and replaced with new mortar. This process involves several steps but is an inexpensive project for homeowners armed with the right tools and knowledge. The basic steps involved are:

  1. Cut out the masonry joints with a grinder then clean up the dust and debris.
  2. Mix up new mortar – type N is a softer, more flexible mortar that works great for brick steps.
  3. Fill the joints with the new mortar using a grout bag or masonry trowel.
  4. Press the mortar into the joints with a flat jointer.
  5. Gently brush off excess mortar.
  6. Run the flat jointer over the mortar to slick the joint, ensuring that it is sealed and waterproof.

While repointing works well when only the mortar joints need to be repaired, alternative action needs to be taken if your steps are separating or you have bricks that are loose or damaged.

How to repair brick steps

Whether you need to do brick repairs or simply reattach loose bricks, many of the same repointing steps can be followed. If your bricks are crumbling, they will need to be chiseled out, and you will need to get new bricks to match the color and style of the existing bricks. When placing the bricks into the stairs, it is essential that they are flush and level with the adjacent bricks. Pack the holes in the brick with mortar to help bonding the bricks together and use a rubber mallet and a level or straightedge to make sure everything is square.

If your brick steps are pulling away from your home, it could be a result of natural settling or a more serious foundation problem. Sometimes brick ties or jacking can be used to fix this problem, but in severe cases, the whole set of stairs may need to be rebuilt. It’s a good idea to have a professional evaluate the problem and potential solutions because uneven or sloping brick steps can pose a safety risk.

How to Repair Brick Mortar

brick wall with a lot of damage

Brick is a charming and enduring material that has been used by builders for centuries. However, when the mortar between the bricks starts to crack and deteriorate, prompt repairs need to be done to ensure that the brick remains intact and lasts for years to come.

How to fix cracked mortar between bricks

The type of repairs the mortar needs will depend on the size and scope of the cracks. A scattering of small, surface level cracks in the mortar is normal and not usually cause for concern, although fixing cracked mortar in bricks will help slow down further deterioration. If the mortar between your bricks just has some hairline cracks in a few places, then brick caulking could be an option to fix them and prevent them from getting bigger. Even small cracks can lead to water infiltration, so applying a waterproof brick caulk will seal the cracks and stop moisture from seeping in. Although brick caulking is a great quick fix for small superficial cracks, it isn’t going to work for larger cracks or crumbling mortar. 

How to fix crumbling mortar between bricks

Larger cracks and crumbling mortar in multiple areas need to be swiftly addressed to avert any further damage to the brick and mortar. Repointing and tuckpointing are two methods for fixing brick mortar that is cracked and crumbling. Repointing is the process of repairing damaged mortar by removing it and filling it with new mortar. Tuckpointing is a similar process where the deteriorated mortar is removed, and the mortar joints are filled with mortar that closely matches the color of the bricks. A second, narrow line of mortar in a contrasting color is then applied down the center of the mortar joints. Repointing is a good option if you just need to repair the bricks, but tuckpointing increases the aesthetics of your structure by giving your brick a crisp, clean appearance that helps give it a fresh look.

What to use to repair brick mortar

When you find yourself in need of brick mortar repair, it is important to utilize the right tools and materials for the job. Because older brick and mortar were made from softer materials, it is imperative that you use the right type and strength of mortar, so your brick and the integrity of your structure aren’t compromised. There are four main types of mortar mix – N,O, S, and M. Each type has different ratios of sand, cement, and lime to create mortar that has differing levels of flexibility, bonding properties, and compressive strength. Choose a mortar mix that will work for the type and age of your structure, the location of the repairs being made, and your local climate. Specialized tools such as an angle grinder with diamond blade, a tuckpointing trowel, a hawk board, and a jointer tool will be beneficial if you decide to tackle the project yourself.

How much does tuckpointing brick cost?

Because of the precision and expertise needed for tuckpointing brick, it’s a good idea to think about hiring a professional tuckpointing company. If you decide to have a professional handle the job, know that you will most likely receive an estimate based on the square footage of the area you need fixed. Repointing costs are cheaper, at around $3 to $15 per square foot. Brick tuckpointing requires more labor, which typically makes up the majority of the cost, and ranges from $5 to $25 per square foot. Factors such as the height, size, and shape of your home, as well as the condition of the brick, can affect the final costs.

While some basic maintenance and repairs are easily completed by handy homeowners, there are a lot of components to consider when choosing the right fix, tools, and materials. Consider hiring a professional to complete the job to ensure that further damage isn’t done that affects the integrity and stability of your brick.

 

The Art of Brickwork Repair: Preserving Structural Integrity with Skill

Posted on by
brick wall lit by a light

Brick is a timeless and long-lasting building material that has been used to build many structures throughout history due to its strength, durability, and beauty, along with its insulating and fire-resistant qualities. Although brick is sturdy and enduring, it does require regular maintenance and repair to counteract the effects of moisture, weathering, and other environmental factors. Whether the mortar is deteriorating, or the bricks are cracking and crumbling, you must address any problems directly in order to prevent further damage to the brick and avoid structural integrity issues.

Patching Brick Mortar

If your bricks are still completely intact, but the mortar between them has begun to show signs of deterioration, you have some options for just patching or repairing the mortar joints. The type of fix needed will depend on the severity of the mortar degradation, but it is imperative that you get it taken care of as quickly as possible. The longer mortar is left to break down, the more issues it can cause in the long run. Mortar that contains cracks or is crumbling will allow more moisture in, which can cause damage to the bricks or result in mold, mildew, or wood rot. Over time, this can affect the stability and integrity of the structure. It’s best to stop these problems before they ever start, so caulking or mortaring bricks is a critical part of maintaining a brick home. Brick caulking, repointing, and tuckpointing are all remedies for mortar that is failing. Which option you choose will depend on if your mortar has minimal cracks or if it has large cracks and is crumbling, as well as aesthetic preference.

Brick Caulking

Brick caulking is the simplest, cheapest fix for repairing brick mortar but is only an option for isolated, hairline cracks. It is not going to be sufficient for larger cracks and crumbling mortar across multiple areas. However, if you have just begun to notice small surface cracks in a few places and want a quick fix, brick caulking could work to slow down further deterioration. Make sure to use a caulk that is specifically designed for brick. The standard caulk that you use on your bathtub or around your windows isn’t going to cut it, and exterior trim caulk is only appropriate for areas where the trim and the brick meet. Using a waterproof brick caulk, also called concrete caulk or mortar caulk, that is designed to adhere to masonry helps to seal tiny cracks in the brick and mortar and can prevent moisture from seeping in thus causing further damage.

Brick caulk comes in many different varieties, so there are several factors to consider when deciding which one to use, including local weather and climate; if it is connected to anything (such as windows, doors, trim, or other bricks); and the material of the surface (e.g., painted or unpainted, porous or nonporous). The color of brick caulk can vary by manufacturer, with some offering dyed options. If you will be putting it on a painted surface, you need to ensure the caulk you use is paintable. Caulk can be applied using a caulking gun or caulk tube, so take application into consideration as well.

How to Repair Brick Mortar

When your brick mortar requires more repair than a bit of caulking will fix, then it is time to look into repointing or tuckpointing your brick. Repointing and tuckpointing are both methods of repairing the mortar joints in brick and become necessary when the mortar is deteriorating to the point of crumbling and falling out of the cracks in order to prevent further damage to the brick and mortar. Repointing is the process of repairing deteriorating mortar by removing it from joints and replacing it with new mortar, whereas tuckpointing is the process of repairing damaged mortar by removing it, replacing it with new mortar in a color that closely matches that of the bricks, and then filling the center of the new mortar joint with a straight, thin line of mortar in a contrasting color. In tuckpointing, because the first layer of mortar blends with the color of the bricks, the contrasting fillets serve to give the wall a crisp, clean appearance. Repointing, on the other hand, typically gives the mortar joints a soft, wavy look because the edges of the bricks won’t be square, a fact which the repointed mortar will only serve to highlight.  Tuckpointing is typically done to repair damaged mortar, but it can also be used to simply enhance the aesthetics of a structure or as a preventative measure against future damage.

Repointing and tuckpointing can both be done as do-it-yourself projects, although using professionals to complete the job will likely result in a more polished finished product. Tuckpointing, especially, is a time and labor-intensive process that requires a great deal of precision to create the illusion of perfectly straight mortar joints. If the fillets are crooked or off center, the whole project is going to look sloppy. Also, the new mortar being applied needs to be weaker than the bricks or it can destroy them over time. Additionally, if bricks need to be replaced, especially in exterior walls, it is definitely a job for a professional mason or tuckpointing contractor. Because these walls are often load-bearing, the integrity of your home could be affected if the repairs aren’t handled correctly.

Whether you choose to hire a professional or DIY the project, there are some basic steps to the tuckpointing process.

  1. Deteriorating mortar needs to be removed to a depth of ¾ to 1 inch using a hammer and chisel or specialized tools such as a raker bar, angle grinder, or tuckpoint grinder.
  2. Once the damaged mortar is cleared out, clean up the dust and debris to allow the new mortar to bond better.
  3. Mix up the new mortar, so it is weaker than the bricks and closely matches them in color. Adding dye or pigment to the mix will help you achieve this, but it could be a time-consuming process to get it just right.
  4. When the mortar is mixed up to the correct consistency and color, it’s time to fill in the joints using a tuckpointing trowel and hawk board. Horizontal joints should be filled first, followed by the vertical ones.
  5. Smooth the mortar to match the existing joint type using a jointer tool.
  6. Wait until the mortar has hardened slightly, then use a brush to clean excess mortar from the bricks.
  7. While the mortar is still pliable, make straight grooves down the center of the joint.
  8. Apply the contrasting putty to the center of the grooves to form the fillets, cleaning up any excess to ensure straight, even lines.

What to Use to Repair Brick Mortar

If you need to repoint or tuckpoint brick, you need to make sure you have the proper materials to complete the repairs. There are a variety of mortar mix types, so it is important to research which one will work best for your project. Mortar mix is categorized into four main types – N, O, S, and M – based on the ratio of cement, lime, and sand used to produce varying levels of bonding properties, flexibility, and compressive strength. When choosing which type is most appropriate for your repair, it is important to take into account climate, the age of your structure, the location of the repairs being made, and the type of structure you will be using it on. Type N is considered to be a general purpose mix that can be used on interior and exterior structures and is the mortar that is most popular among homeowners. Using the correct mortar mix, along with the proper tools, is imperative to completing the job correctly and making sure you don’t cause more damage to your structure.

Brick Repair

While brick caulking, repointing, or tuckpointing are sometimes all it takes to repair damage and restore the beauty of your home, there are times when they just aren’t enough. When brick and mortar repair are both required, the task becomes far more arduous. It requires specialized tools and knowledge to ensure that the repairs are completed correctly in order to prevent further harm. Exterior and other load-bearing walls can be compromised if brick repair isn’t done correctly, so it might be a good idea to open your preferred search engine and type in “brick wall repairs near me” to find a local professional that can safely restore your brick. Or, if your project is less sensitive, and you think you might be able to handle the job yourself, it’s best to understand the basic steps required to do it.

  • Remove the damaged brick: Use a chisel and hammer to break up the damaged brick and surrounding mortar into pieces and then remove them. You could also drill small holes in the center of the brick first to help get the process started. Be careful not to damage any of the other brick and mortar around the area. After you have removed all of the pieces, clean out all of the dust and dirt then rinse the entire area with water.
  • Mix and apply the mortar: Mix up the mortar you will use, making sure to match the existing mortar color as closely as possible. Use a pointing trowel, apply a 1-inch layer of mortar to the bottom of the opening as well as the top and ends of the new brick.
  • Insert the replacement brick: Set the brick on top of the pointing trowel. Slide the trowel and brick into the cavity then slide the brick into the recessed area, holding the trowel on the mortar to prevent it from being disturbed. Work the brick around to try to make the mortar joints even then use a straightedge to push the brick level with the wall.
  • Tool the joints: After the mortar has hardened slightly, scrape or brush off excess mortar. Once the mortar is hardened to the point of being able to just dent it with a little pressure, use a jointer tool to tool the joints so that they match the style of the original joints.

Whether you need to repair or replace brick and mortar, it is important to understand when and why it needs to be done. When in doubt, consult a professional to help you with whatever repairs your brick structure may need. It is important to maintain your brick and complete repairs promptly and accurately to preserve its integrity and beauty for years to come.

Revitalizing Your Brickwork: The Art of Tuckpointing

Posted on by
blank brick wall

Bricks are a classic, durable material for interior and exterior walls, fireplaces, and chimneys. A popular choice for many historical homes and buildings due to their beauty and functionality, bricks could be made by hand, or later on mass-produced by machines, and provided both insulation and fire-resistance. However, as these historic structures age, the mortar filling the joints can deteriorate, causing cracking and crumbling. Tuckpointing offers a long-lasting, aesthetically pleasing solution to mortar degradation.

What is brick tuckpointing?

While brick is a sturdy construction material that has proven it can stand the test of time, the same cannot be said for mortar. The typical lifespan of mortar is 20 to 30 years as opposed to bricks, which can withstand centuries when properly cared for, so chances are good that you will have to replace or repair the mortar multiple times in order to prolong the life of your home or building. Exposure to moisture and varying temperatures can cause the mortar between bricks to break down over time, and if not properly addressed, can lead to water damage in your brick structure. It is imperative to maintain your brick home in order to prevent further issues, such as structural instability, mold, mildew, or wood rot. Brick tuckpointing is one way to help counteract the effects of deterioration and refers to the process of repairing deteriorating mortar by removing the old mortar, replacing it with mortar that closely matches that of the bricks, and then filling the center of the new mortar joints with a straight, narrow line of mortar in a contrasting color. This enhances the visual appeal of the brick because it gives the mortar joints a crisp, clean appearance.

Tuckpointing vs. Repointing

An alternative to brick tuckpointing is repointing, and while these terms are sometimes used interchangeably, there is a distinction between the two. Tuckpointing and repointing are slightly different approaches to repairing brick mortar, although tuckpointing is sometimes done as a preventative measure or for visual enhancement. While a few small cracks are not cause for concern, repointing or tuckpointing brick becomes necessary when the mortar starts to crumble and fall out of the cracks. As with tuckpointing, repointing is used to repair mortar when it begins to deteriorate in order to prevent further damage to the brick structure. However, repointing is the process of repairing deteriorating mortar by removing the old mortar and replacing it with new mortar. Because it does not use the second layer of contrasting mortar on top, repointing doesn’t result in the same aesthetically pleasing appearance as tuckpointing. It tends to have a soft, thick, wavy look as opposed to the thin, clean lines of brick tuckpointing.

Brick Tuckpointing Installation

Bricks used to be made using softer materials, so it is important to use the correct methods and materials for tuckpointing, especially in older buildings. For this reason, brick tuckpointing installation is often best left to the professionals. While it may seem more cost effective to do-it-yourself, if you don’t use the proper mortar when tuckpointing old brick, you can end up causing more damage to your structure. Walls were built from softer bricks, and lime was used in mortar mix, resulting in a softer mortar. Modern brick and mortar tend to be made harder, so if a historic brick wall is repaired using modern material, it can result in crumbling brick and compromise the integrity of your structure. Tuckpointing is also a labor-intensive process that requires a lot of skill and precision to apply the contrasting fill lines to the mortar joints. Consider using knowledgeable tuckpointing contractors who have the expertise and experience necessary to do the work correctly and ensure a clean, professional-looking end result.

How to Tuckpoint Bricks

After assessing your brick structure and determining which areas are in need of repair, there are several steps involved in tuckpointing bricks. Whether you decide to tackle the job yourself or hire a professional to complete it for you, here is a play-by-play of the process.

  1. The first thing that needs to be done is to remove the crumbling mortar from between the bricks, approximately three-fourths to one inch deep. While professionals use specialized tools or equipment, DIYers can use a hammer and chisel to complete the job. Fair warning, though, this can be a time-intensive task, especially if you have a lot of mortar to remove. It is also a good idea to wear protective face gear to prevent breathing in the dust and debris or getting it in your eyes.
  2. After removing all of the damaged mortar, be sure to clean out the mortar joints completely of dust and debris. This can be done using a masonry brush or something with high air pressure, such as a leaf blower, and will allow the new mortar to adhere more strongly to the old brick and mortar.
  3. When everything has been properly cleaned, it’s time to mix up the new mortar. It’s important to use mortar that is a close color match to your brick. This is done by mixing dyes or colored pigment with mortar mix, and it can take some trial-and-error to get just the right ratios. If all else fails, take a small sample of your mortar to a masonry supply store and have them match the color for you. Make sure to write down the amounts of pigment and mortar that were needed, so you will have that information on hand for future reference. Remember, also, that the mortar needs to be weaker than the bricks, or you could damage your bricks.
  4. Once you have the correct color of mortar, it’s time to fill in the mortar joints. Using a tuck pointer trowel, push the mortar into the joints from a hawk board. You could also use a mortar pointing gun, but it is crucial that your mortar is the right consistency. The mortar gun will become clogged if the mortar is too dry and could end up being more of a hassle. Start by filling the longer horizontal joints first and then fill the shorter vertical ones. Making sure that you are using the appropriate size tools for your joints will aid you in not getting mortar all over the bricks.
  5. After applying the mortar to the joints, you will need to smooth the wet mortar to match the existing type of joint. Common joints include concave, V, flush, and extruded for external walls and raked, grapevine, struck, and weathered for internal walls.
  6. Wait for the mortar to harden slightly then brush away any excess mortar on the bricks.
  7. While the mortar is still pliable, mark straight lines into the center of the newly filled mortar joints with a tuckpointing tool. Using a straightedge is beneficial for getting the lines as straight as possible.
  8. Finally, apply a lighter colored putty to the grooves to form the contrasting fillets, making sure to clean up any excess. This step requires a great deal of precision to give the finished wall the desired clean, crisp appearance that tuckpointing aims to achieve.

Tuckpointing Tools

Masonry tuckpointing requires a variety of tools and materials, especially if you want more professional looking results. It is important to determine what you will need and make sure you have everything on hand when you begin your project. While some of these may not be necessary for your specific job, let’s take a look at the various tools you could use to complete each step.

  • Mortar removal
      • Hammer
      • Chisel
      • Mortar raking tool

How to Clean Brick After Tuckpointing

If you do decide to go the DIY route, once the tuckpointing process is complete, it is important to allow the mortar a little time to harden and brush away any excess from the bricks. Use a soft brush and be sure to avoid digging into the newly filled mortar between the bricks. Whether you tackle the project yourself or hire professionals to get the job done, after the mortar has had time to cure completely, it is important to complete regular cleaning and maintenance on your structure in order to prolong the life and beauty of your brick. In order to protect the tuckpointed brick, it is essential to keep it free of anything that can trap moisture in masonry. Because moisture will erode brick and mortar if left unchecked, it is important to regularly check for mold, mildew, and moss and clean the surfaces thoroughly if you find them. Following these steps can ensure that you clean your tuckpointed brick safely and effectively.

Thoroughly spray the area with water: Brick and mortar are both porous materials. If you apply cleaner directly to them, it will immediately be absorbed and can leave you with discolored brick. To prevent the cleaners from soaking in, you must first saturate the brick and mortar with water. This allows the cleaner to sit on top instead of soaking in and do its job of removing dirt.
Use the right cleaning products: Harsh chemicals can be damaging to brick and mortar, so it is imperative to use the right types of cleaning products. Use a mild household cleanser, bleach, masonry cleaner, or even a vinegar, dish soap, and water mixture to clean your brick and mortar. Be sure to read what type of materials a cleaner is meant for to ensure that you don’t destroy your structure.
Avoid vigorous cleaning: Using the right type of cleaning tool is also crucial to not damaging tuckpointing. A soft plastic or nylon bristled brush, or a masonry sponge are all good options for cleaning brick and mortar. A stiff, wire-tipped brush can be too abrasive and destructive to the newly repaired brick.
Pressure washing: Pressure washing can be a good option for newer, stronger brick, but it should not be used on older brick because it could end up causing damage.

If in doubt about how to clean your brick, it may be best to consult with a professional. Regular cleaning and maintenance are essential to increasing the longevity and stability of your brick structure but cleaning them incorrectly can do more harm than good.
