To perfectly apply Drylok in a basement, first prepare the walls by cleaning and repairing them, then apply at least two coats using a 3/4-inch nap roller or stiff-bristled brush, ensuring thorough penetration into the masonry’s pores, especially in corners and along the floor-wall joint. Back-brush or back-roll the first coat to fill pinholes, and allow sufficient drying time between coats before inspecting for missed spots. [1, 2, 3, 4]
Preparation
- Clean the Walls: Remove any loose paint, dirt, or efflorescence. [5, 6, 7, 8]
- Repair Damage: Fill any cracks or imperfections to ensure a smooth, even surface for the product. [5, 6, 9, 10]
- Dry the Area: Ensure the walls are completely dry before application, as standing water can hide leaks. [11]

Application Tools
- Brush: Use a stiff-bristled brush or a brush specifically designed to hold heavy-bodied coatings, like a DRYLOK® Brush. [1, 14]
- Roller: A 3/4-inch nap roller is recommended for applying the first coat to back-brush and fill in pores. [1, 4]
Application Steps
- Stir the Product: Stir the Drylok vigorously to ensure it has a consistent texture. [1, 2]
- First Coat:
- Load the brush generously with Drylok. [3]
- Apply to the prepared surface, working the product deep into the pores. [2, 3]
- Pay extra attention to foundation levels and inside corners. [3]
- Apply a few extra inches onto the floor at the wall-to-floor joint to create a stronger barrier. [3]
- Back-Brush or Back-Roll: After applying the first coat with a roller or brush, use a roller or brush to work it into any pinholes or pores in the masonry. [1, 4]
- Second Coat: Apply a second coat of Drylok for enhanced protection and a complete waterproof barrier. [1, 2]
- Inspect: After the final coat has dried, inspect the surface for any missed spots or imperfections and fill them in. [2]
- Clean Up: Clean tools with soap and water immediately after use. [2]
