PART 3 - EXECUTION
Examine all construction substrates and conditions under which concrete floor sealer material
(SG3) is to be installed. Do not proceed with the concrete floor sealer installation until
unsatisfactory conditions are corrected.
Assure before application that surfaces to be treated do not contain any kind of sealer
(sodium, potassium, etc.), chlorides, oil, grease, dirt, curing compounds, or any substance
that might act as a bond breaker.
Existing slabs with unknown history or slabs with previous coating failures: Provide concrete
core analysis from independent lab for ION and IR analysis, recommended by SG3
manufacturer. Do not proceed until manufacturer has analyzed test results.

Anhydrous Calcium Chloride Testing as per ASTM F-1869, and/or RH as per ASTM F2170
and/or concrete core analysis.
1. Before installation of concrete floor sealer (SG3): use tests carried out by
Architect/Engineer during study phase, and confirm by testing through installer or
Protect adjacent surfaces not designated to receive SG3 concrete floor sealer.
1. Remove existing floor coverings, coatings and adhesives down to bare concrete, curing
compounds, efflorescence, dust, grease, laitance, etc. with steel shot blasting, abrasive
(sand) blasting or grinding using a diamond cup blade. Acid etching is not allowed.
2. Assure that all slabs have concrete surface profile ICRI CSP 3 - 5 for mechanical bond.
Smooth surfaces are not acceptable, they must be steel shot blasted.
3. Burn off reinforcing fibers and collect and vacuum remains.
4. Repair defective areas such as honeycombs, cracks or other defects with a suitable
repairing or manufacturer recommended mortar or crack mending resin for nonmovement cracks and joints.
5. Treat saw cut and expansion joints as per manufacturer’s application guideline.
6. Install cementitious underlayment, leveling mortars, flash patching, on top of surface
applied concrete floor sealer (SG3).
7. Contact manufacturer for recommendations for areas where a separation screed is
8. Treat oil contaminated areas as per manufacturer’s recommendations.
9. Carefully rinse or pre-dampen several times all the surfaces to be treated with clean
water, leave no standing water.
A. Mix concrete floor sealer (SG3) material in proportions recommended by manufacturer’s printed
B. Apply concrete floor sealer (SG3) material in quantities as per manufacturer's specifications and
1. Apply SG3 in one coat at 100 SF/gal = 240 SF/2.4 gal kit (~16 mils DFT).
2. Apply using roller or notched squeegee to the still moist substrate, and carefully scrub it into
the pores with a long handled scrub brush. Follow with a roller to achieve a uniform coverage.
C. Contact manufacturer if a sand broadcast is desired. Walk over fresh/wet SG3 using shoes with
FIELD QUALITY CONTROL

A. It is not necessary to re-test the substrate for moisture emissions prior to installing the coating or
Remove left over materials and any foreign material resulting from the work from the site.
Clean adjacent surfaces and materials. Protect the underlayment from abuse by other trades
with plywood, Masonite or other suitable protection materials.
