UGL Drylok WetLook High Gloss Sealer Gallon 28913

This product is a clear, non-yellowing, water-based acrylic coating formulated for use on interior or exterior masonry surfaces. Provides superior hardness and durability. Protects against efflorescence (white, powdery, salt-like deposits) visible on the masonry.

Built in flash rust resistance prevents orange staining of surface when applied to masonry containing natural metals. Excellent chemical resistance to de-icing salts, gasoline, oil and weathering. Blush resistant formula will not turn white or haze when exposed to moisture after full cure. Ideal for horizontal and vertical surfaces such as walkways, driveways, pavers, brick, poured concrete, Chattahoochee stone, and artificial stone. 

Preparation
Remove all dirt, wax, dust, mildew, and loose or scaling material with a scraper, wire brush, or stiff bristle brush.* Grease, wax, and oil should be removed by scrubbing with a heavy duty detergent in warm water. Rinse thoroughly with clean water and allow to dry. Using a pressure washer? Do not use on a pressure setting above 1750 psi, to avoid damaging the concrete. Remember, concrete acts like a sponge. Pressure washing and general cleaning may trap residual moisture in the concrete.
To check for trapped moisture, tape a 12” x 12” piece of 3 mil plastic or aluminum foil tightly to the surface on 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.
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® WetLook Clear High Gloss Penetrating Sealer 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, rinse and allow to dry.
DRYLOK® Etch will also properly prepare the concrete’s profile to accept the coating. Properly prepared concrete should look and feel like medium grit sandpaper. If the concrete remains smooth, repeat the etching procedure. You can test the concrete porosity by sprinkling a few drops of water onto the surface in several areas. If the water is readily absorbed, you are ready to apply the coating. If it beads or sits on the surface, additional cleaning and etching is needed. Rinse it thoroughly with clean water and allow it to dry for 24 hours.
Patch all holes and cracks with a suitable cement-based patching compound. Be sure to smooth the patch evenly. Allow the patched area to dry thoroughly.

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. Do not thin the product. DRYLOK® WetLook Clear High Gloss Penetrating Sealer appears milky in the can but dries clear. Apply by brush, roller, spray, or squeegee. Spread evenly and do not allow puddles or a heavy surface film to occur. Apply one thin coat using even strokes. Extremely porous surfaces may require a second coat. Allow 2 hours drying time between coats. Additional coats will cause the surface to become slippery when wet.
On light-colored surfaces, some darkening may take place. Test in an inconspicuous area to be sure darkening does not occur. DRYLOK® WetLook Clear High Gloss Penetrating Sealer may be applied to surfaces previously coated with a similar treatment. For best results, test a small area for proper adhesion prior to coating the entire surface.
DRYLOK® WetLook Clear High Gloss Penetrating Sealer may be applied over existing paints and coatings. In addition to normal surface preparation, old glossy surfaces must have the gloss removed by using sandpaper. Remove all sanding dust with a vacuum or tack cloth. Many previously coated surfaces may only require 1 coat.
Optional
Up to 2 ounces of DRYLOK® Non-Skid Texture Additive may be added to DRYLOK® WetLook Clear High Gloss Penetrating Sealer to improve traction.

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