DRYLOK® Natural Look Sealer

DRYLOK® Natural Look Sealer

Just like natural and man-made stone, concrete, stucco and masonry are porous materials that will start to break down, dust, pit, crack, and/or stain when subjected to weather, water, oil, and UV rays. The only way to prevent damage and deterioration is to protect your surfaces with a good quality sealer. Specially formulated DRYLOK® Natural Look Sealer soaks right in and provides an invisible coat of protection that looks beautiful and natural. Use on interior and exterior masonry surfaces, including concrete driveways, basement floors, garage floors, concrete sidewalks, patios, terrazzo, brick, and slate.

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 DRYLOK® Concrete Cleaner Degreaser according to manufacturer’s directions or use a heavy duty detergent in warm water. Rinse thoroughly with clean water and allow the surface 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® Natural Look 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 DRYLOK® Concrete Patch or 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® Natural Look Sealer appears milky in the can but dries clear. You can apply by brush, roller, spray, or squeegee. Spread it 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 6 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. May be applied to surfaces that have been previously coated with a similar treatment. For best results, test a small area for proper adhesion prior to coating the entire surface.

Disposal

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

USAGE STATEMENT: Prior to use, carefully read the product label and follow the directions. For technical information, warnings, cautions, notices, and additional information, download and read the documentation available on this website.

* WARNING: If you scrape, sand or remove old paint, you may release lead dust. LEAD IS TOXIC. EXPOSURE TO LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE. Wear a NIOSH-approved respirator to control lead exposure. Clean up carefully with a HEPA vacuum and a wet mop. Before you start, find out how to protect yourself and your family by contacting the National Lead Information Hotline at 1-800-424-LEAD or visit www.epa.gov/lead.
