CrystalCoat 329 Polyaspartic Coating - Clear

PRODUCT STORAGE: Store product at normal room temperature before use. Continuous storage should be between 60°F and 90°F. Low temperatures or temperature fluctuations may cause crystallization.

SURFACE PREPARATION: The most suitable surface preparation is a brush blast (shot blast) to remove all laitance and provide a proper surface profile. All dirt, foreign contaminants, oil, and laitance must be removed to ensure a trouble-free bond to the substrate. A moisture test should be performed to confirm the concrete is dry. This can be done by placing a 4’ x 4’ plastic sheet on the substrate and taping down the edges. If after 24 hours the surface beneath the plastic remains dry, the substrate is suitable for coating. This test also helps identify potential hydrostatic pressure issues that may later cause disbonding. For direct-to-concrete applications, testing should confirm a moisture vapor emission rate below 3 lb/24 hr/1,000 ft² per ASTM F1869.

PRODUCT MIXING: The mix ratio is 12.95 lb Part A to 9.3 lb Part B. Standard packages are pre-measured and should be mixed as supplied. After combining Parts A and B, mix thoroughly using slow-speed mixing equipment (such as a jiffy mixer) until the material is uniform and streak-free. Transfer the mixed material into a second pail and remix before application. The material is then ready for use on the properly prepared substrate.

PRIMING: A suitable primer should be used prior to application. Refer to the technical data sheet for primer recommendations. Regardless of primer use, a test patch is strongly advised to verify adhesion performance under actual service conditions.

PRODUCT APPLICATION: Apply the mixed material by brush, serrated squeegee, or roller. Maintain recommended temperature and relative humidity conditions during application and curing. The product may be used as a final topcoat to seal broadcast flake or quartz systems. Use an air release roller if required to eliminate entrapped air. Improper mixing may result in product failure. Relative humidity significantly affects cure characteristics: higher humidity shortens working time and accelerates cure, while lower humidity extends working time. Mix only quantities that can be placed within the available working time. Ensure tie-ins to previously applied material are completed within the allowable window, as previously placed material may tack off quickly.

RECOAT OR TOPCOATING: This material may be applied in multiple layers to increase build or used as the final sealing topcoat over aggregate-filled systems. Before recoating, confirm the previous layer has tacked off. Lower temperatures will extend cure time before recoating or topcoating can proceed.

CLEANUP: Use xylol.

FLOOR CLEANING: Some cleaners may affect floor color. Always test cleaning products in a small, inconspicuous area using your intended cleaning method. If no adverse effects are observed, proceed with full cleaning.

RESTRICTIONS: Restrict the floor to light traffic and non-harsh chemicals until fully cured (refer to technical data for full cure times). Keep the surface dry during the full cure cycle. Depending on the system build, surfaces may be slippery when wet or contaminated. Maintain a clean and dry surface.
