PART 3 - EXECUTION
Examine all construction substrates and conditions under which concrete floor sealer material is to be
installed. Do not proceed with the concrete floor sealer installation until unsatisfactory conditions are
Protect adjacent surfaces not designated to receive concrete floor sealer.
1. Provide surface profile ICRI CSP 2 - 5 (ICRI, Des Plaines, IL, Guideline No. 03732.) on smooth
troweled slabs with steel shot blasting. Smooth surfaces are not acceptable, they must be
Remove dust, grease and oil with high pressure water blasting.
Apply chemical detergent solution (“degreaser”).
Scrub in chemical solution with stiff-bristled broom or scrubbing machine.
Collect and dispose of solution.
Repeat process as needed to achieve acceptable results.
Repair defective areas such as honeycombs, cracks or other defects with a suitable repairing or
manufacturer recommended mortar.
Treat saw cut and expansion joints as per manufacturer’s application guideline.
Carefully rinse all the surfaces to be treated with clean water, leave no standing water.
10. Do not let surface dry out. Surface must be kept wet to prevent oil from raising.
Mix concrete floor sealer material in proportions recommended by manufacturer.
Apply concrete floor sealer material in quantities as per manufacturer's specifications and
recommendations to still damp surface.
Apply in one coat for oil contaminated slabs at rate of 100 SF/gal (0.77 kg/m ).
Apply using short nap roller or 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.
Broadcast clean, dry, fresh water washed and dried #20 silica sand (0.5 to 1.0 mm) to “rejection” (full
broadcast) or at a rate of 30 lb/100 SF (1.5 kg/m ) into the fresh concrete floor sealer where a
subsequent cement-based leveling course (underlayment) or epoxy based top coating follows.
Where specified install floor covering as per manufacturer’s specifications and recommendations.
Note: Water based adhesives under VCT, sheet vinyl, linoleum, rubber backed carpet or other nonbreathable flooring systems require a cementitious underlayment on top of the concrete floor sealer for
their curing process. Consult adhesive manufacturer for recommended minimum thickness of
Remove left over materials and any foreign material resulting from the work from the site.
Clean adjacent surfaces and materials.
