Brick is a material that has been used for various purposes in construction for centuries, and remains a common choice. While brick was once used as a structural material, it is most commonly used for decorative purposes today. Many structures that are still standing today have bare foundations made from brick, and while they are still strong, they may require waterproofing to prevent or correct further or existing problems. The application of modern waterproofing material is a generally straightforward and affordable task, and can usually be completed by just about anyone, using only basic tools.

Things You'll Need

  • Shovel
  • 6-Inch masonry brush
  • Cement-based masonry sealer (pre-mixed)
  • Hudson sprayer
  • Brick sealer
  • Paint brush (any size)

Exterior

Remove dirt from the foundation wall, using the shovel to expose the entire wall to the concrete footing.

Clean any debris and dust from the wall, using the 6-inch masonry brush. The wall should be clear of loose material, but does not need to be completely clean.

Apply the pre-mixed cement-based masonry sealer to the brick foundation wall, using the 6-inch masonry brush. Pre-mixed sealer is packaged for immediate use and does not need to be mixed, although some brands may recommend stirring the material before use--be sure to read and follow the application directions listed on the product packaging. Apply additional coats as directed on the packaging.

Interior

Clean any debris and dust from the wall, using the 6-inch masonry brush. The wall should be clear of loose material, but does not need to be completely clean.

Pour the brick sealer into the Hudson sprayer, and close the lid tightly.

Evenly apply the brick sealer to the brick foundation wall, using the paint brush to coat any divots or chips on the brick surface. Apply additional coats as directed on the sealer packaging.
