SHALI SUPER REZ-SEAL
Acrylic Curing and Sealing Compound
SHALI SUPER REZ-SEAL Acrylic Curing and Sealing Compound
DESCRIPTION Shali Super Rez-Seal® is a high solids copolymer, that cures concrete and provides a protective coating for interior and exterior concrete including terrazzo surfaces. It bonds tenaciously to concrete forming an inert, impervious film that is resistant to the alkali from fresh cement, salts and many construction stains. It impregnates the top surface of a floor, making it highly resistant to the penetration of dirt and staining materials. Shali Super Rez-Seal® complies to ASTM C 309 Types 1 & 1D, Class B.
AREAS OF APPLICATION • Industrial Floor Slabs
• Parking Garages • Exterior Pavements and roads
• Warehouses • Walls and Columns
• Dry Shake Hardened Floors • Terrazzo Floors
• Passenger and freight Terminals
FEATURES & BENEFITS • Higher solids content for increased curing efficiency. • Provides a clear curing film for new concrete. • Seals all concrete surfaces - old or new and easy to clean. • Hardens new concrete by promoting a proper cure for improved abrasion resistance. • Dustproofs concrete by impregnating surface pores with tough durable film. • Protects fresh concrete from rain damage after drying. • Compatible with many paints, adhesives, and resilient floor coverings. • Higher coverage rates than with standard solids formulas.
CURING For the best cure of freshly placed concrete, apply Shali Super Rez-Seal® as soon as possible after finishing operations and /or immediately after the disappearance of the "sheen" of surface moisture. Application should be made with a high pressure industrial sprayer, lambs wool applicator, short nap roller or brush. DO NOT cover more area than can be worked in 10 minutes as the Shali Super Rez-Seal® membrane will start to dry. Specially formulated Super Rez-Seal aluminised will improve surface reflectivity.
SEALING When sealing old concrete, the surface must be clean and dry. Remove contaminants and stains such as waxes, grease and oil with strong soaps or caustics rather than acids. Badly worn or porous areas may need a second application to attain a uniform seal and surface gloss. Apply Shali Super Rez-Seal with a high pressure industrial sprayer, lambs wool applicator, short nap roller or brush.
Anti-Spall Treatment Use 2 coats of the standard Shali Rez-Seal formulation.

PRECAUTIONS • Do not apply to concrete surfaces or at ambient temperatures below 10oC. • Do not apply over bleed water or free standing water. • Spray application of the Shali Super Rez-Seal formula must be done with a high pressure or airless industrial sprayer. • Do not apply concrete to receive concrete toppings, epoxy or urethane-based coatings or adhesives. • Do not use in areas, which may be subject to hot oil, grease, or fat spillages such as kitchens.
