Do not proceed with the concrete floor sealer installation until <br />unsatisfactory conditions are corrected.</p> <p>B.</p> <p>Assure that surfaces to be treated do not contain any kind of sealer.</p> <p>C.</p> <p>Anhydrous Calcium Chloride Testing as per ASTM F-1869: <br />1. Before installation of concrete floor sealer: use tests carried out by Architect/Engineer <br />during study phase, and confirm by testing through installer or independent laboratory <br />prior to installation of concrete floor sealer. <br />2. After installation of concrete floor sealer: not required by manufacturer of specified <br />concrete floor sealer, unless specified during bid stage.</p> <p>PREPARATION <br />A.</p> <p>Protect adjacent surfaces not designated to receive concrete floor sealer.</p> <p>B.</p> <p>Substrate preparation: <br />1. Remove existing floor coverings, coatings and adhesives down to bare concrete, curing <br />compounds, efflorescence, dust, grease, laitance, etc. with steel shot blasting, abrasive <br />(sand) blasting or grinding using a diamond cup blade. Acid etching is not <br />recommended. <br />2. Assure that all slabs have surface profile ICRI CSP 3 - 5 (ICRI, Des Plaines, IL, <br />Guideline No. 03732.) for mechanical bond (i.e. medium grit sandpaper). Smooth <br />surfaces are not acceptable, they must be shot blasted. <br />3. Burn off reinforcing fibers and collect and vacuum remains. <br />4. Repair defective areas such as honeycombs, cracks or other defects with a suitable <br />repairing or manufacturer recommended mortar. <br />5. Treat saw cut and expansion joints as per manufacturer’s application guideline. <br />6. Install cementitious underlayment, leveling mortars, flash patching, on top of surface <br />applied concrete floor sealer.</p> <p>072600-3 or 099656-3</p> <p>7. Carefully rinse or pre-dampen several times all the surfaces to be treated with clean <br />water, leave no standing water. <br />3.3</p> <p>INSTALLATION <br />A. Mix concrete floor sealer material in proportions recommended by manufacturer. <br />B. Apply concrete floor sealer material in quantities as per manufacturer's specifications and <br />recommendations. <br />1. Apply in one coat at specified rate for moisture vapor emission rate (MVER) up to 25 lbs/24 <br />2 <br />hrs*1000 SF (<5.0 g/hr/m ). <br />2. Apply using roller or squeegee to the still moist substrate, and carefully scrub it into the pores <br />with a long handled scrub brush. Follow with a roller to achieve a uniform coverage. <br />C. Immediately broadcast clean, dry, fresh water washed and dried #20 silica sand (0.5 to 1.0 mm) <br />2 <br />to “rejection” (full broadcast) or at a rate of up to 30 lb/100 SF (1.5 kg/m ) into the fresh concrete <br />nd <br />floor sealer where a 2 coat or subsequent top coating such as epoxy, epoxy terrazzo, cementbased topping, underlayment, polyurea, polyurethane, etc., follows. <br />E. Where specified install leveling <br />recommendations.</p> <p>course</p> <p>as</p> <p>per</p> <p>manufacturer’s</p> <p>specifications</p> <p>and</p> <p>F. Where specified install floor covering as per manufacturer’s specifications and recommendations. <br />G. Note: <br />1. Water based adhesives under VCT, sheet vinyl, linoleum, rubber backed carpet or <br />other non-breathable flooring systems require a cementitious underlayment on top of the <br />concrete floor sealer for their curing process. Consult adhesive manufacturer for <br />recommended minimum thickness of cementitious underlayment. <br />2. Pressure sensitive adhesives installed directly over broadcasted concrete floor sealer require <br />a longer "tack" time than listed on manufacturer's literature to prevent adhesive moisture <br />entrapment. <br />3.4</p> <p>ACCEPTANCE <br />A.</p> <p>Remove left over materials and any foreign material resulting from the work from the site.</p> <p>B.</p> <p>Clean adjacent surfaces and materials. <br />END OF SECTION</p> <p>072600-4 or 099656-4</p> <p>Project: ........
