Primer for Concrete Prep and Treatment
Cured films are quite flexible, yet have high bond and tensile strength. This enables the product to reconstitute and stabilize severely deteriorated surfaces. Although SLPV 1:1 Primer has good water, solvent and chemical resistance, it is primarily designed to be an intermediate bond coat so that high performance and special purpose coatings can be applied to existing substrates.
Substrates should be dry and free of debris, dirt, moss, algae, mildew or oil. Loose or peeling paint must be removed. Make repairs and tighten or replace fasteners prior to the application of primer. High pressure washing is an effective cleaning method.
Method of Application
A combination of rubber squeegee, roller and brush are most practical on flat surfaces. A pressure pot spray system may be used if pot life limitations can be adhered to. Recommended Spreading Rate
When spread at 320 sq. ft. per gallon, a 5 mil dry film will result on a smooth surface. Although this is sufficient for bonding to the substrate, it may be difficult to achieve in practice. A squeegee and roller application will usually result in covering 150-175 sq. ft. per gallon which results in an average dry film thickness of 8-9 mils. Rough or porous surfaces will require a lower coverage per gallon. This product should be applied to smooth surfaces. If using mortar/concrete make sure the surface is skimmed smooth prior to surface prep for ponds.
General dry time for SL EP11 1:1 Primer is 10 hours. You are able to apply our SLPV coatings over the primer even if it still slightly tacky. You want to be sure that the SLPV Pond Coating is applied within 48 hours of applying the primer and no rain has fallen on the primer.
