DetailsK-FLEX® 374 Protective Coating
K-FLEX® 374 Protective Coating is a water-based coating specially formulated for application to elastomeric insulation surfaces. Fast drying and white in color, this protective coating offers UV resistance and is ideal for indoor and outdoor applications.K-FLEX® 374 Protective Coating is available in gallon containers.
K-FLEX® 374 Protective Coating can be applied with a brush or short-nap roller, or sprayed. For best appearance, two coats are recommended. It should be stirred thoroughly and applied to a clean, dry surface which is free of dirt, oil, or other contaminants. If the surface needs cleaning, use a fast-drying non-residue cleaner such as denatured alcohol. The coating should be applied above 50°F and allowed to dry for 1 hour between coats, or the adhesion may be adversely affected.
See Technical Bulletin TA1 for equipment recommendations.
Do not add water to the product; thinning with water will adversely affect the coating. Use fresh, clean water for clean up.
