INSTALLATION:

Substrate: Substrate must be structurally sound, clean, free from dust, wax, release agents, curing compounds, sealers and oils. Smooth surfaces should be scarified. Mix 1 part of SP-888 with 1 part clean water (by volume).

APPLICATION:

Apply diluted SP-888 with a garden sprayer on clean prepared substrate and broom into substrate surface. (USE SOFT BRISTLE BROOM.) SP-888 can also be applied with a short nap paint roller or paint brush.

Allow SP-888 to dry to a clean film before installing S-2200. If substrate absorbs SP-888, apply a second coat.

CLEAN-UP:

Clean tools and spills with soap and water before SP-888 dries.

COVERAGE:

1 gallon SP-888 with 1 gallon of clean water will cover 400-600 sq. ft.
