UGL Drylok Floor & Wall Clear Masonry Waterproofer Gallon 20913

UGL Drylok Floor & Wall Clear Masonry Waterproofer is a non-pigmented masonry waterproofer specially formulated to use on bare masonry floor and wall surfaces. Provides a durable, waterproof easy to clean, non-yellowing high gloss finish.

Preparation
DRYLOK® Floor & Wall Masonry Waterproofer may be applied on a slightly damp surface, but best results are obtained when the surface is dry, clean, and free of grease, oil, form release compound, and paint. Remove dust, dirt, and any loose or broken mortar with a wire brush*. Old paint in poor condition should be removed by wire-brushing, sandblasting or other suitable methods. If you see white, powdery, crystal-like deposits on the surface, they are naturally-occurring, water-soluble salt compounds in the masonry, pushed out by water intrusion. When the water evaporates, the salt residue remains. This effect is called efflorescence and, because it prevents DRYLOK® Floor & Wall Masonry Waterproofer from properly bonding to the surface, it must be removed. Treat it with DRYLOK® Etch®** (liquid or powder formula) or muriatic acid according to the manufacturer’s directions. Proceed to rinse and allow the surface to dry. Since efflorescence occurs naturally, we cannot warrant against it reoccurring.
Patch all cracks and holes with DRYLOK® Fast Plug®. Wet the surface to be patched and, so DRYLOK® can better anchor itself into the wall, back chisel the areas to be patched into shapes like an inverted ​“V”. Apply and smooth the patch so it’s even with the surface around it. As DRYLOK® Fast Plug® sets rapidly, mix only what you’ll use in 3 to 5 minutes. Also, be sure to seal the area where the floor and wall meet. Often, when concrete floors cure, they shrink and pull away from the wall, creating a space where water can enter.
Floor Preparation
Highly troweled or extremely smooth concrete floors must be acid etched or mechanically abraded to achieve the proper profile. Treat the surface with DRYLOK® Etch®** (liquid or powdered) or muriatic acid, according to the manufacturer’s directions. A properly prepared concrete floor should look and feel like medium grit sandpaper. Repeat the etching procedure until the proper texture is achieved.
Test the concrete’s porosity and check for residual sealers by sprinkling a few drops of water on surface. If the water does not readily penetrate into the prepared concrete, additional acid etching is required. Remove any residual acid etching material from the surface, rinse it thoroughly and allow it to dry.
To check for trapped moisture, affix a 12” x 12” piece of 3 mil plastic or aluminum foil to the surface, taping it tightly along all four edges. Remove it after 24 hours. If the surface side of the plastic or foil is damp, allow additional drying and repeat the test.

Application
Schedule your project when both air and surface temperatures are 50°F or higher and, for best results, wait for a dry (rain-free) period. Stir DRYLOK® thoroughly before and during application — do not thin. The product will appear milky in the can but it dries clear. Apply the first coat to bare masonry with a three-eighths-inch nap roller (19 mm), a foam roller, a DRYLOK® Brush, a good quality nylon bristle brush, or a sprayer. If using a brush, work DRYLOK® Floor & Wall Masonry Waterproofer into the pores of the masonry. If rolling or spraying, back brush if necessary to fill in all the pores and pinholes. Give the first coat 3 hours to dry, and then apply a second coat using a roller, brush or sprayer (download our Spray Specs).
For proper coverage, a minimum of 2 coats is required. After the second coat, carefully inspect the entire surface for pinholes. In areas where pinholes are still present, apply an additional coat of DRYLOK® Floor & Wall Masonry Waterproofer. If leaking is still present after two coats, it indicates that pores or pinholes are still open. Paint these areas again.
Floor Application
To achieve uniformity, apply 2 coats of product, making sure to apply the second coat in a cross direction to the first coat. The surface can be subjected to light foot traffic within 4 hours and heavy foot traffic within 24 hours. DRYLOK® Floor & Wall Masonry Waterproofer is not recommended for surfaces that are subject to vehicular traffic. If you plan to cover the surface with flooring or carpeting, allow the final coat of DRYLOK® Floor & Wall Masonry Waterproofer to dry for 24 hours. Only use water base adhesives when installing flooring. If topcoating, use a water-based paint or coating. Any screws, nails or anchors that penetrate the coating will nullify the waterproofing properties. Lift and place items on floor surfaces to avoid marring.
NOTE: Waterproofed surfaces may become slippery when wet. If slip-resistance is desired, add 2 – 4 ounces of DRYLOK® Non-Skid Texture Additive to each gallon.

Disposal
Dispose of contaminated absorbent, container and unused contents in accordance with local, state and federal regulations.
