PART 3 - EXECUTION 3.1
EXAMINATION A.
3.2
Examine all construction substrates and conditions under which waterproof flooring materials are to be installed. Do not proceed with the waterproofing application until unsatisfactory conditions are corrected.
PREPARATION A.
Protect adjacent surfaces not designated to receive waterproof flooring material.
Substrate preparation:
096700-3 Fluid-Applied Flooring in Mechanical Rooms
1. 2. 3. 4. C. 3.3
3.4
Rinse surfaces to be waterproofed (excluding drywall or similar) with clean water to saturated surface dry (SSD) condition, with no standing water on horizontal surfaces.
INSTALLATION A.
Mix waterproof flooring material in proportions recommended by manufacturer.
Apply waterproof flooring material in quantities as per manufacturer's specifications and recommendations.
Taping: 1. Apply waterproof flooring material by brush in a six to seven inch (15 – 18 cm) wide strip coat centered over all joints, cracks, penetrations and changes of plane to be taped. 2. While this coat is still wet, unroll joint sealing tape into the coating and apply a coat of waterproofing flooring material over the tape, smoothing out wrinkles and fishmouths.
Sealing around PVC pipe penetrations: 1. Place sealing gasket over pipe and mark size of penetration, then cut out necessary opening (penetration). 2. Apply one prime coat two-component waterproofing material over concrete and exposed PVC pipe. 3. While this coat is still wet, place and firmly press sealing gasket into the coating and cover it with a top coat of two-component waterproofing material.
E.
Base Coat: 1. Apply waterproof flooring material by trowel, squeeguee or roller at rate of 250 SF/77 lb unit (23.2 m2/35 kg unit) (approx. 40 mils (1.0 mm) wet film thickness). 2. Color: Standard gray or color as specified by the Architect. 3. While this coat is still wet, immediately place and firmly embed reinforcement fabric into the wet coating.
F.
Top Coat/Wear Course: Allow base coat to sufficiently dry 1. Apply waterproof flooring material by roller at rate of 250 SF/77 lb unit (23.2 m2/35 kg unit) (approx. 40 mils (1.0 mm) wet film thickness). 2. Color: As specified by the Architect.
CURING A.
3.5
Remove oil, grease, dirt, loose particles, remains of form oils, water repellents, rust or other coatings by steel shot-blasting, wet or dry sand blasting, or other mechanical means to produce surfaces suitable for maximum bond of waterproof flooring material to concrete. Follow manufacturer's instructions to clean and prepare surfaces, cracks and joints. Repair damaged and deteriorated concrete to acceptable condition using compatible products. Mask off all adjoining areas that are not to receive the waterproof flooring material.
Follow manufacturer's general instructions for curing and hardening of waterproof flooring material. Do not use water for curing. Waterproof flooring material is self-curing.
FIELD QUALITY CONTROL A.
Thickness: Total approximate thickness of waterproof flooring material shall be 60 mils (1.5 mm) dry film.
Do not overcoat waterproof flooring material with solvent-based materials.
096700-4 Fluid-Applied Flooring in Mechanical Rooms
3.6
Prime and protect alkali sensitive metals such as copper, aluminum, galvanized or zinc treated metal first with a primer, before over-coating with waterproof flooring material. Follow manufacturer’s recommendations for primer material.
Where a uniform color is desired, application of an elastomeric paint or water based acrylic stain is recommended.
ACCEPTANCE A.
Remove left over materials and any foreign material resulting from the work from the site.
Clean adjacent surfaces and materials. END OF SECTION
