Acid Etching or Bead blast. All surfaces to be coated must be unsealed and abraded to a
minimum 5 mil profile using acid etching or bead blasting. Completely remove existing
adhesion affecting substances/contaminants like curing compounds, finishes, stains, oil,
grease, bitumen, penetrated mastics and adhesives including primers, and substances
detrimental to bond or connection of new materials, and expose clean sound surfaces.
Employ wet bead blasting for interior surfaces and for exterior surfaces where required.
B.
Sealer application: Prepare surfaces in accordance with the coating manufacturers printed
instructions. Remove contaminants including loose mortar, rust and other products of
corrosion, disintegrated concrete, and other substances that could interfere with adhesion
and penetration of the coating system to the substrate.

APPLICATION
A.
Install by experienced mechanics with methods and spray or roller equipment
recommended by coating manufacturer, after surfaces to be treated are dry.
B.
Mix and install floor sealer in accordance with manufacturer's recommendations. Install
evenly over the surface in 2 coats at approximately 200-400 square feet per gallon per
coat.
C.
Keep traffic from treated surfaces until the material is thoroughly dry.
