Kaufman Products Surepoxy Protective Coating WD

SurePoxy Protective Coating WD is suitable for use on both interior and exterior surfaces. When the clear is used on fresh concrete, it serves as a concrete cure and heavy-duty sealer without the need to etch or scarify the surface first. It is recommended for poured in place, precast, tilt wall concrete. Use on bridges, factory floors, parking structures, walkways, wall and columns.

It serves as an excellent base for subsequently applied 100% solid, emulsion or solvent borne epoxy and urethane systems.

Surface preparation: 

Fresh Concrete: when #800 clear is applied to fresh concrete as a curing compound or primer, no preparation is necessary.

Existing concrete: correct surface preparation is the most critical part of any floor coating project. The desired adhesion to the substrate will not be obtained the preparation does not leave the surface free of foreign matter, including curing compounds and form release agents. Concrete surfaces must be clean and sound. We recommend strict adherence to international concrete repair institute (icri) guideline # 03732, selecting and specifying concrete surface preparation for Sealers, Coatings, and Polymer Overlays (1997). This standard details proper surface preparation and techniques for all types of concrete repair and coatings applications. See complete directions in our General Epoxy Instructions.

If applying, #804 Gray over #800 Clear within the first 2 months, and the #800 is in excellent shape, surface preparation only requires a clean, contamination free surface. If the prime coat has been down longer than that or if the #800 has worn off, apply the #800 again, wait overnight and then put the #804 top coat on.

Mixing: Stir both components and combine into a clean container. Combining ratio is 1:1 by volume. Stir both components thoroughly with a paint mixer attachment using a low speed (500 rpm) power drill. Allow to sit for 20 minutes before using.

Ambient and surface temperatures must be a minimum of 50 o F and a maximum of 90oF . After the 20-minute induction period, stir again with the slow speed power drill. Pigmented formulations must have a uniform color without streaks. Apply with brush, roller, or spray within 2 hours of mixing. WD can be sprayed with a Graco GH 533, 30:1 Bulldog Sprayer or comparable airless sprayer. Use a .030-.040 fan tip depending on desired output rate

Curing Compound: When applying to fresh concrete, wait until all troweling operations are complete and the top surface will not be marred by the application and apply promptly.

Sealing: If the concrete was cured with the #8900 clear and it is still in good shape, simply cleaning off all foreign matter and recoating with #804 is all that is necessary. If the surface has never been cured with the #800 or if it has worn off, apply #800 properly and allow drying overnight. After one day, apply #804 properly on top of the #800. If an additional coat of #804 is desired, allow an overnight dry before application of each coat. In areas with poor ventilation, wait an additional time. Use a minimum of two coats. A third coat achieves maximum protection.

Non-Slip Surface: Although, SurePoxy Protective Coating WD is not a slippery product, it can become so, if foreign matter lays on it. To provide non-slip properties, simply sprinkle an excess of approximately 1/3 lb./ft2 of SurePoxy Aggregate Mortar on the surface of the first coat while it is still wet. When it is dry, sweep off excess and apply second coat.

Clean Up: Use SurePoxy Protective Coating WD Thinner.
