Advantages

• Crystal Clear-A is much tougher than traditional acrylic sealers. The high gloss created by Crystal Clear-A lasts up to 70% longer.
• Crystal Clear-A completely resists discoloration from ultraviolet light exposure.
• Crystal Clear-A cures concrete to ASTM C1315 standards to minimize cracking and increase the strength of concrete.
• Protects surfaces against deicing chemicals, fertilizers, salts, grease, oil, alkalies, mild acids and detergents.

Uses

• Cure freshly poured exterior plain, colored, stamped or exposed aggregate concrete to ASTM 1315 where superior curing efficiency is required.
• Seal, harden, and dustproof existing concrete particularly architectural or residential concrete exposed to freeze-thaw or ultra violet light.
• Enhance the color and gloss of pigmented or stamped concrete.

Directions for Use

Mixing: Clear Crystal Clear-A is packaged ready to use. Do not dilute.
Surface Preparation: If using to cure fresh concrete, apply as soon as all bleed water has dissipated. If applying as a sealer for older concrete, clean thoroughly with high-pressure water and allow the concrete to thoroughly dry.
Application: Apply uniformly leaving no pinholes or gaps. Do not allow the material to puddle.
Spray Apply with a low pressure, solvent resistant, airless, sprayer equipped with a fan nozzle orifice of 0.030 to 0.035” at 1 gpm. The optimum spray pattern is an 8” to 12” fan. Hold sprayer tip 8” to 12” from the surface of the concrete.
Roller Apply: Use a short nap (1/4” max) solvent resistant roller.
Application Rate:
Curing: 300 ft2/gal (7 m2/L)
Sealer: 350 to 450 ft2/gal (9 to 11 m2/L). Unsealed concrete may require an optional second coat.
Clean-up: Clean tools with solvent such as xylene immedi-ately after use.
