If you own a brick house, then you’re well aware of the dangers of moisture damage to brick. If you don’t own a brick house but are thinking about purchasing one, it’s important that you understand this durable material. The biggest enemy to any form of masonry is moisture. Bricks are porous, and as such, they are prone to absorbing water and cracking or crumbling. The same goes for mortar.
One of the best ways to protect your brick house from moisture damage is by sealing it. Sealing a brick house can help prevent any issues that you may have with water damage for a period of time. Learn all about sealing a brick house here!
Step 1: Inspect the House
If you’re considering sealing your house, you’ll need to inspect it to make sure that sealing it is suitable. Then, you’ll need to prep it for sealing. When inspecting the home, look for the following issues that may be present:
- Mold or mildew buildup
- Crumbling or cracking in the bricks or mortar
- Salt lines from flooding
- Creeping plants, like ivy
- Areas with heavy dirt or mineral deposits
- Old paint
If you notice that your brick and mortar are heavily damaged, either through cracking or crumbling, sealing your house may not be the first thing you should do. The house may need to be tuckpointed, or repaired further. If so, give us a call. If your home seems to be in good condition, then you’ll be ready to prep it.
Step 2: Prep the Brick
Preparing the brick is an important step. As bricks are porous, it can be assumed that they’ll absorb things like moisture and dirt over time. They may also have residual sealant in them if they’ve been sealed before. As such, it’s important to wash them and prepare them for sealing. To wash the brick, follow the steps below:
- Remove any dirt, debris, or old paint from the surface gently
- Pull back any debris from the bottom layers of brick
- Apply a mildew and mold remover using a scrub brush
- Power wash the brick from top to bottom, making sure to wash away any dirty water
- Allow the brick to dry completely
Once you’ve finished prepping the brick, it’s time to get the workspace ready.
Step 3: Protecting Surfaces and Yourself
Treat your house as if you’re painting it. That means covering things surrounding the house with drop cloths, taping off windows and doors, and wearing eye protection, a mask, and rubber gloves. If you’ve done all that, then you’re ready to seal.
Step 4: Seal the Brick
You can use a pump sprayer or the traditional method of a roller to apply brick sealant. Regardless, make sure that you coat the surfaces evenly, and allow them to dry completely. Temperatures need to be between 40 and 90 degrees fahrenheit for proper application, and the sealer needs to be allowed to dry without weather interference.
Key Takeaways
Sealing brick is a great way to keep your home in great shape for years to come. However, not all homes are ready to be sealed. If the masonry surfaces of your home need repair, be sure to give us a call. We can help you get your brick tuckpointed, and get it in the best shape before being sealed!
