Our experts demonstrate how to create a lasting waterproof barrier that will keep your basement dry for years. By combining DRYLOK®’s reliable waterproofing coating with Sika PRO Select’s advanced sealants, you’ll learn how to keep your basement fully protected against moisture and water damage.
Prepare the Surface
Clean your basement walls and floors thoroughly to remove dirt, dust, and loose debris. Remove efflorescence (white, chalky residue) using DRYLOK® Etch for a clean, smooth surface. If the walls remain damp, apply DRYLOK® Wet Wall Bonding Primer to improve adhesion and enhance waterproofing performance.
Repair walls and seal openings
Repair missing mortar using Sikaflex®+ Mortar Fix Sealant. Let it cure for 7 days before applying DRYLOK® Original or DRYLOK® Floor & Wall.
Seal gaps around doors and windows using Sikaflex®+ Construction Sealant. Allow it to cure for 7 days before applying DRYLOK® Original or DRYLOK® Floor & Wall.
Seal floor and wall joints
Fix leaks at the floor-wall joint using DRYLOK® Fast Plug for a quick, watertight seal. For larger cracks up to 1.25 inches, use Sikaflex Self-Leveling Sealant. Structural repairs may require Sikacryl PowerSet Instant Concrete Repair or a full slab repair.
Repair Floor Cracks
For cracks smaller than 1 inch wide and ½ inch deep, insert a backer rod and fill with Sikaflex®+ Crack Flex Sealant. Once cured (7 days), apply DRYLOK® Floor & Wall or DRYLOK® E1 Concrete Floor Paint. For expansion joints or wider gaps, use Sikaflex Self-Leveling Sealant for a smooth, durable repair.
Apply Waterproof Coatings
Once all repairs are fully cured (7 days), apply DRYLOK® Original, DRYLOK® Floor & Wall, or DRYLOK® E1 Concrete Floor Paint, depending on your surface type. Use a brush for tight areas and a roller for even coverage, creating a complete, long-lasting waterproof seal.
