APPLICATION

SURFACE PREPARATON

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

Epoxy.com Product #693 Methyl Methacrylate (MMA) Sealer and Coating requires
the addition of  Epoxy.com Product #695 MMA Hardener to start the hardening
process. The amount of hardener must be adjusted to the respective surface temperature (see table
below). At temperatures below 40�F, Epoxy.com Product #696 Accelerator must be used in addition to the amount of hardener used at
the 40�F level (about � oz by
vol./gal. @ 32°F up to 2.0 oz by vol./gal. @ -20°F).

For outdoor applications add 1% Epoxy.com Product #693 UV Inhibitor at a
rate of 1% by volume. Pigmented topcoats are achieved by adding pigment packs (1 quart per 5 gallons
resin) to Epoxy.com Product #693 Methyl Methacrylate (MMA) Coating.
Apply material with a notched trowel or squeegee and back roll with a short nap
mohair roller.

CLEAN UP

Clean skin with soap and water; use MEK, xylene, or clean proprietary epoxy thinners for equipment.
Consult Material Safety Data Sheet for safety and health precautions.

COVERAGE

will yield 16-32 mils at 50-100 square feet per gallon, average.

is 6 months in the original unopened containers.

HELPFUL HINTS

Adequate cross ventilation should be provided. Good ventilation during the processing ensures a good cross
linking and hardening. Read, understand and follow Material Safety Data Sheets and Application Instructions
prior to use.

Use only as directed. If substrate and/or material temperature is above 90°F, DO NOT apply material.
