II.
SURFACE PREPARATION
Surface Preparation is the most critical portion of any
successful resinous flooring system application. All substrates must be properly
prepared to a minimum surface profile of CSP-2 as outlined in
Epoxy.com Surface Preparation Procedures. Specific attention should be paid to the
following:
A. Concrete Placement--An efficient vapor barrier should be under
slabs on or below grade to prevent moisture migration. A moisture vapor
treatment may be necessary.
B. Curing and Finishing Techniques of the Concrete
Substrate
C. Age of Concrete
D. Previous Contamination of the Substrate
E.
Present Condition of the Substrate Also, the temperature and humidity conditions
of the area to receive the flooring system should be checked. An optimum room
temperature of 75°F with a minimum slab temperature of 60°F is required for
proper cure of the resin flooring system.

INSTALLATION
A. Product #12 Epoxy Primer -
www.epoxy.com/12.aspx
1. Mixing
a. Stir each component prior to
mixing.
b. Mix two (2) parts by volume of Part A (Resin) with one (1) part by
volume of Part B (Hardener) for three minutes with a low speed electric drill
mixing paddle.
c. If thinning is desired, add no more than one pint of xylene or
MEK per gallon of epoxy at time of mixing.
d. Do not mix more material than can
be applied in 15-20 minutes (less time in hot temperatures). Do not leave
mixed material in the pail for longer than 3 minutes or working time will be
significantly reduced!
2. Application
a. Pour mixed resin onto the prepared
concrete.
b. Spread with either a flat trowel or squeegee, or roller to a coverage of 200
to 275 ft per gallon. If smaller batches are used, this product can be
installed with the "dip and roll" method.
c. Back roll with a short nap roller.
d. Allow primer to
cure 8-12 hours (at 75 degrees F) prior to topcoating. A fast cure formulation
is available to reduce re-coat window to 4-6 hours. If primer is to be allowed
to sit for longer than 24 hours, sand primer before topcoating.

1. Mixing Product #633
High Build Chemical Resistant Novolac Epoxy Floor Coating
a. Stir each component prior to mixing.
b. Mix two (2)
parts by volume of Part A (Base) with one (1) part by volume of Part B
(Hardener) for three minutes with a low speed electric drill mixing paddle.
Add optional Epoxy.com Anti-Skid fine at a rate of 8-12 volume ounces
per gallon of mixed epoxy and mix until well dispersed (typically 1
minute).
c.
Mix only the amount of material that can be immediately poured out.
2.
Application
a. Immediately pour mixed material onto floor in strips and spread
at a rate of 160- 200 ft per gallon with a squeegee. If smaller batches
are used, this product can be installed with the "dip and roll" method.
Alternately you can use the dip and roll method if you make small enough
batches.
b. Back roll immediately
with a short to medium nap roller. Do not backroll excessively.
3. Allow to cure
overnight or a minimum of 12 to 16 hours at 75 degrees F.
4. Apply second coat the same as step 2.
Allow to cure 24 hours for light traffic, 48 hours for heavy traffic.
For very hot tires, and chemical exposure wait 5-7 days for full chemical cure.
