Q:

How do you apply Drylok paint?

A:

Properly applying Drylok paint requires three steps: preparing the surface, patching cracks and holes and applying the paint. First clean the surface with a wire brush to remove loose or broken dirt and mortar from the surface. Treating the surface with a solution or muriatic acid is also required. Rinse the solution from the surface and allow to dry.

After cleaning the surface, fill all cracks and holes with a plugging material. Soak and back chisel the area in the shape of an inverted "V" to allow the patch to lock and heal properly. When patching the surface, be sure to cover the space where the floor and wall join together.

After cleaning and filling the cracks, stir the Drylok paint thoroughly. The Drylok paint must be stirred vigorously before and during the application process. Use a 3/4-inch nap roller or high-quality nylon bristle brush to apply the paint.

Drylok must be properly applied for sufficient waterproofing. One gallon of Drylok pain covers an 8 by 10 foot area. Apply a minimum of two coats to assure ample waterproofing. Make sure the Drylok sufficiently dries before applying a second coat. After the second coat, inspect the wall surface for pinholes. All pinholes must be painted over with an additional coat to ensure waterproofing.
