- Advantages
- Crystal Clear is much tougher than traditional acrylic sealers. The high gloss created by Crystal Clear lasts up to 70% longer.
- Crystal Clear completely resists discoloration from ultraviolet light exposure.
- Crystal Clear 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.
Applications & Uses
- Markets
- Compatible Substrates & Surfaces
- Uses
- Cure freshly poured exterior plain, colored, stamped or exposed aggregate concrete to ASTM C309 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
Mixing: Do not dilute. CRYSTAL CLEAR is packaged ready to use. Gently stir or agitate prior to use.
Surface Preparation: If using to cure fresh concrete, ap-ply when application will not mar the surface within two hours of bleed water dissipation.
If applying as a sealer for older concrete, clean thoroughly with high-pressure water and allow the concrete to thor-oughly dry. Surface must be clean and free from dirt, dust, laitance, oil, grease, paints, curing agents, tilt up bond breakers, or other contaminants that would prevent proper adhesion. Joints to receive joint sealant should be masked or taped off prior to application.
Application: Apply uniformly leaving no pinholes or gaps. Do not allow the material to puddle.
Spray Apply: Use a low pressure, solvent resistant, air-less sprayer equipped with a fan nozzle or solvent resis-tant hand pressurized sprayer with a ‘Cats Eye’ nozzle with an orifice of 0.030 to 0.035” at 1 g.p.m. The optimum spray pattern is an 8 to 12 inch fan. Hold sprayer tip 8 to 12 inches from the surface of the concrete.
Roller Apply: Use a short nap (1/4” max) solvent resis-tant roller.
An optional second coat may be applied to a tack free sur-face at right angles to the first. Coating breathability will be reduced as film thickness increases. Thinner coats have improved esthetic qualities.- Cleanup
Clean tools immediately after use with POLYSEAL SOL-VENT™ or xylene.
Regulatory & Compliance

Technical Details & Test Data
- Limitations
- Crystal Clear is not for use on interior surfaces.
- Do not use on surfaces to receive concrete overlays or toppings. Always test for compatibility and adhe-sion.
- Do not use as a bond breaker for tilt wall construction or on surfaces requiring rubbing.
- Do not apply to joints or channels scheduled to re-ceive elastomeric caulks.
- Do not use if ambient or substrate temperature is be-low 40°F (4°C). For best results condition material to a minimum of 50°F (10°C) prior to application.
- Do not apply in the presence of foodstuffs. USDA compliance pertains to fully cured coating.
- Coating may be softened and lifted by gasoline or other strong organic solvents such as xylene, toluene, or lacquer thinner. Solvent, gasoline, hydraulic fluids, peanut oil, and cooking oils must be cleaned quickly to prevent damage.
- Safety Data Sheet and all label precautions must be fully understood before using product.
- Quality curing or sealing compounds may darken or highlight the color variations naturally pre-sent in con-crete.
