Characteristics: <br />® <br />1. Product: <br />VAPORTIGHT COAT -SG2 <br />2. Component-A and B: <br />Precise blend of white and yellowish liquid <br />3. Compressive Strength: <br />>11,000 psi (>80 Mpa) (ASTM C-579, Modified) <br />4. Flexural Strength: <br />>4,000 psi (>27 Mpa) (ASTM D-638, Modified) <br />5. Bond/Adhesion: <br />>500 psi (>3.5 Mpa) at 28 days on damp/moist concrete <br />(ASTM D-4541, Modified) <br />2 <br />6. Permeance: <br /><1.0 perm (<5.7E-08 grams/Pa*s*m ) (ASTM E-96) <br />7. Alkaline Resistance: <br />up to pH 14 (ASTM D-1308) <br />8. Cured for installation of flooring: <br />12–16 hrs at 73 deg F (23 deg C) <br />9. pH on cured surface: <br />7</p> <p>PART 3 - EXECUTION <br />3.1</p> <p>EXAMINATION <br />A.</p> <p>3.2</p> <p>Examine all construction substrates and conditions under which concrete floor sealer material is to be <br />installed. Do not proceed with the concrete floor sealer installation until unsatisfactory conditions are <br />corrected.</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. Provide surface profile ICRI CSP 2 - 5 (ICRI, Des Plaines, IL, Guideline No. 03732.) on smooth <br />troweled slabs with steel shot blasting. Smooth surfaces are not acceptable, they must be <br />roughened. <br />2.</p> <p>Remove dust, grease and oil with high pressure water blasting.</p> <p>3.</p> <p>Apply chemical detergent solution (“degreaser”).</p> <p>4.</p> <p>Scrub in chemical solution with stiff-bristled broom or scrubbing machine.</p> <p>5.</p> <p>Collect and dispose of solution.</p> <p>09601-2</p> <p>6.</p> <p>Repeat process as needed to achieve acceptable results.</p> <p>7.</p> <p>Repair defective areas such as honeycombs, cracks or other defects with a suitable repairing or <br />manufacturer recommended mortar.</p> <p>8.</p> <p>Treat saw cut and expansion joints as per manufacturer’s application guideline.</p> <p>9.</p> <p>Carefully rinse all the surfaces to be treated with clean water, leave no standing water.</p> <p>10. Do not let surface dry out. Surface must be kept wet to prevent oil from raising. <br />3.3</p> <p>3.4</p> <p>INSTALLATION <br />A.</p> <p>Mix concrete floor sealer material in proportions recommended by manufacturer.</p> <p>B.</p> <p>Apply concrete floor sealer material in quantities as per manufacturer's specifications and <br />recommendations to still damp surface. <br />2</p> <p>1.</p> <p>Apply in one coat for oil contaminated slabs at rate of 100 SF/gal (0.77 kg/m ).</p> <p>2.</p> <p>Apply using short nap roller or squeegee to the still moist substrate, and carefully scrub it into the <br />pores with a long handled scrub brush. Follow with a roller to achieve a uniform coverage.</p> <p>C.</p> <p>Broadcast clean, dry, fresh water washed and dried #20 silica sand (0.5 to 1.0 mm) to “rejection” (full <br />2 <br />broadcast) or at a rate of 30 lb/100 SF (1.5 kg/m ) into the fresh concrete floor sealer where a <br />subsequent cement-based leveling course (underlayment) or epoxy based top coating follows.</p> <p>D.</p> <p>Where specified install floor covering as per manufacturer’s specifications and recommendations.</p> <p>E.</p> <p>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 <br />their curing process. Consult adhesive manufacturer for recommended minimum thickness of <br />cementitious underlayment.</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>Project: ........
