APPLICATION
SURFACE PREPARATION
Surface Preparation is the most critical portion of any successful
resinous flooring system application. All substrates must
be properly prepared as outlined in Epoxy.com
Surface Preparation Guide.
MIXING & APPLICATION
Mix each component of Epoxy.com Product #231 Water Emulsion Primer and Sealer prior to combining in the proper
mixing ratio, (2 parts Part A-Resin to 1 part Part B-Hardener by volume).
Only mix what can be used in four hours. Allow to stand 30 minutes and mix again.
Apply primer in a thin film with a short nap roller (1/4 inch nap). Do not build film of the primer,
but roll out so that it soaks into the concrete. Two coats of primer may be necessary to
insure uniform wetting and coverage. Second coat can be
applied over wet primer after turning from cloudy to clear.
RECOAT
Epoxy.com Product #231 Water Emulsion Primer and Sealer can be top coated very rapidly. When
primer turns clear (from milky), it is possible to apply a water based
topcoat. Follow the following recoat windows:
Water based topcoat - 1-24 hours
100% solid epoxy topcoat - 6-24 hours
Solvent based topcoat - 24-36 hours
