Brick flooring pavers, whether they're made of concrete or natural clay, are quite porous in their natural state and should be sealed to protect the floor from stains and dirt. New brick should be sealed immediately after installation and before the floor is used. Some pavers are sold prefinished with a durable commercial sealer applied to the entire unit. In this case, the pavers do not require sealing after installation, but the grout or mortar between the pavers should be sealed, as it is just as porous as brick.
Before You Begin
Brick masonry sealer is commonly sold in gallon-size containers at home centers and some hardware stores. Before applying it, clean the floor thoroughly to remove all dirt and debris, and let it dry completely. You don’t want to seal a stain into the surface. It's a good idea to test the sealer on a small, inconspicuous area of the floor to see how the finished product will look and to make sure the sealer doesn’t cause streaks.
If the brick floor is newly installed, the installers may have used muriatic acid to clean the surface. The acid must be thoroughly rinsed away or it will continue to eat away at the limestone in the grout, causing whitish dust to rise from between the bricks over time.
Equipment / Tools
- Foam brush
- Paint tray
- Plastic bucket
- Long-handled scrub brush
- Buffing machine (if needed)
- Brick masonry sealer
- Floor wax (solvent-based or water-based)
- Household ammonia
Apply the Sealer
Pour the sealer into a bucket or paint tray and apply it with a foam brush. Apply a thin, even coat over the entire surface of the floor, covering the paver faces and the grout lines between them. Allow the floor to dry completely.
Test the Sealer
Test the sealer by dripping a small amount of water onto the surface of the brick. If the water beads up, you have successfully sealed the brick. If the water soaks into the bricks, clean and dry the floor, then apply a second coat of sealer.
Choose the Proper Wax
There are two main types of wax used on brick floors: solvent-based and water-based. What you use depends upon the wax and polish treatment your floor has seen in the past.
Solvent-based wax is a versatile product that creates a shiny protective coat over sealed brick surfaces. It can be applied to floors that have previously been treated with water-based wax, but the old wax must be stripped from the surface.
Water-based wax is a heavy-duty polish that can be applied directly to unsealed brick and will protect the floor from moisture and stains. Before applying water-based wax, the entire floor must be stripped of any previous applications of wax to prevent wax buildup. Also, all earlier waxes must be water-based; if a solvent-based wax has ever been applied to the floor, a water-based wax cannot be used.
Strip Away Previous Wax Applications
In a plastic bucket, mix up a solution of 1/4 cup ammonia to 8 cups water. Using a mop, apply this to the floor to strip away any previous wax. Go over the floor with the mop several times, then use a long-handled scrub brush to ensure the wax is gone. Rinse the floor with water and let dry thoroughly.
Apply the Floor Wax
The specific steps for applying wax vary by product, so it's important to follow the manufacturer's instructions. Once the floor is clean and dry, some waxes can be applied by hand and buffed with a cloth until the surface is smooth and even. Other waxes require the use of professional buffing machines, which can be rented from local home stores or rental centers.
