Coval Quick Seal and Enhance creates a breathable, stain, graffiti and acid resistant surface in concrete and other porous materials, and may be tinted to achieve stain like effects.

Coval Quick Seal and Enhance may also be used as a primer for other Coval products.

Surfaces must be clean, dry and free of waxes. Use Coval Step #1 Cleaner for Painted Surfaces and then rinse with water. Allow to dry thoroughly. Mask off all areas not to be covered, and provide adequate ventilation. Stir well, before and during application, to maintain suspension of nanoparticles. Plastic Coat is best applied with a HVLP (high-volume-low-pressure) spray system, with a 1.0-1.3 size tip and the pressure set at approximately 25 to 30 psi. Clean-up immediately with acetone.

Note:All equipment must be chemical and acetone resistant.
