Clearshield is an odorless water-based sealer formulated to penetrate the surface of concrete, brick, mortar, tile, stucco and other masonry surfaces. It forms a water repellent shield for long lasting wear. It can be used on vertical and horizontal above-grade surfaces, interior and exterior. Clear Shield protects concrete driveways and walks against adverse effects of deicing salts (chloride ions), water, ice, and weathering damage. It will not discolor concrete. Clearshield-ST is a ready-to-use waterborne blend of siloxanes and silanes designed to penetrate deeply into the surface and to provide a long term protection from water intrusion on to Cantera stone, concrete, block, pavers, flagstone, terra cotta, sandstone and brick. Available in 1 gallon & 5 Gallon sizes.

Surface must be clean and completely dry. Remove any dirt, debris, oil or stains. Any cracks or loose joints must be repaired properly before applying Clear Shield. Pressure wash old concrete or brick with water. For vertical surfaces, use Damtite Concrete Cleaner to remove mildew or efflorescence (salt-like deposits). For new concrete, wait a minimum of 30 days for proper curing before applying.

Stir before using; do not dilute. First apply product to a small test area to insure proper penetration is achieved. Surface density or curing additives on the surface may affect penetration. For vertical surface applications, apply with low pressure sprayer, roller or brush. Start at top of wall and apply sufficient product to allow run down of 6-12 inches (15-30 cm). For horizontal surface applications, apply product liberally to entire surface with sprayer or roller; then broom or squeegee for even distribution and eliminate any puddles. For both vertical and horizontal, apply second coat before first coat dries (wet-on-wet) to ensure complete coverage. Additional coats may be required for very porous surfaces.

(Clearshield) One Gallon – Ranges from 75-125 sq.ft. (7-11m²) per gallon, depending upon porosity and density of surface. (Clearshield-ST) Depending upon porosity of surface, coverage will vary from 75-125 square feet (7-11.6 square meters).
