How To / Videos
Wear eye protection with side shields, chemical-resistant gloves, protective footwear and suitable clothing when using DRYLOK® Liquid Etch. Remove dirt, dust, grease, and oil by washing with a detergent solution or DRYLOK® Concrete Cleaner & Degreaser*. Allow the surface to dry before applying DRYLOK® Liquid Etch.
Apply when air and surface temperature is above 50°F. Surfaces to be treated should be slightly damp. For vertical surfaces, apply DRYLOK® Liquid Etch with an acid-resistant sprayer or a synthetic brush. For horizontal surfaces, apply DRYLOK® Liquid Etch using a plastic garden watering can with a sprinkling head or an acid-resistant sprayer. DO NOT pour onto one spot and brush out over surface. Using a stiff bristle brush or broom, scrub DRYLOK® Liquid Etch into surface until foaming action stops. If the Liquid Etch does not foam, the concrete has been sealed. The sealer must be removed using a suitable chemical remover or surface abrader. Triple-rinse the surface with a strong stream of water, scrubbing while rinsing to ensure removal of all etching material. When dry, check the surface by applying a few drops of water. Water should penetrate quickly. If not, re-apply DRYLOK® Liquid Etch to the affected area as described previously. Allow the surface to dry thoroughly before applying paint or stain. A properly etched horizontal surface should look and feel like 120-grit medium sandpaper. Additional applications may be required when used as a concrete etching compound or when conditions of excessive efflorescence build-up exist.
