How To Repair Paint Peeling from Masonry and Brick

If you have masonry and brick walls in your house, you will almost certainly have to deal with paint peeling off the surface. Although this is a pretty common problem, paint peeling must be immediately addressed. It is very unsightly, sort of robbing your home its usual beauty and charm. To help you, here are some tips on fixing paint peeling from masonry and brick.

  • Know the cause. Excess moisture causes peeling, lessening the adhesive power of the paint to stick to the surface. So before you do any repairs, it is important to find out where excess moisture is coming from. Check both the interior and exterior of the house. Find out if there are cracks and holes that promote water leakage. Downspouts and ceilings should also be inspected. If you see openings both inside and outside of the house, apply sealant or cement right away.
  • Scrape off the flaking paint. You need to use a wire brush to remove the loose paint from the surface of the masonry and brick. Make sure to scrape off as much as you can to prepare the surface for paint reapplication. This will also remove the dirt and dust that have accumulated on the surface.
  • Remove efflorescence. Efflorescence is the chalk-like material adhering to the surface of the masonry and brick. Remove such buildup to keep the integrity of the surface. To do this, you need efflorescence cleaner and a stiff brush. Apply cleaner to the surface and scrub off the chalk-like buildup. Rinse it off with water. Best to use a garden hose for this to jet down the remaining efflorescence. Remember to use gloves and protective eyeglasses.
  • Clean the surface. It is very important to remove dirt, loose paint, and other materials adhering to the surface of the masonry and brick. You can do this with the use of bleach. In a bucket, mix one gallon of water and one cup of bleach. Then use this solution to scrub off the unwanted materials from the surface. When the surface is already clean, rinse it with water. Let the surface completely dry.
  • Apply sealer. The sealer will help protect the masonry and brick paint from moisture and peeling. Make sure to follow the manufacturer’s instructions when applying sealer. Specifically, note how many coats of sealer you should apply.
  • Repaint the masonry and brick. Choose a good paint for your masonry and brick surface. It should have moisture-resistant properties to prevent surface peeling. You can find several paints on the market, but many experts attest to the effectiveness of acrylic paint. Not only does it protect the surface from moisture, it also helps in covering flaws on the surface. Again, make sure to follow the manufacturer’s instructions. And remember to open the windows and doors (if you are painting inside the house) to release paint fumes out of the house.

Remember that masonry and brick repair can be completed in a day to a week, depending on the extent of the damage. So before you begin, make sure you have enough time to complete this.
