PART 3 EXECUTION
A. Obtain Architect's approval of mock-up before installing flooring; see QUALITY ASSURANCE in PART 1.
B. Preparation of Surface:
1. Inspect surfaces to receive flooring and verify that condition is smooth and free from conditions that will adversely affect execution, permanence, or quality of work.
Remove all projections, all debris detrimental to flooring system, and dirt, oil contaminates, grease, and surface coatings affecting bond.
2. Notify Architect in writing prior to commencing work of any conditions deemed unsatisfactory for the installation; installation of flooring materials is understood as acceptance of the substrate as satisfactory.
3. Concrete: Test for moisture content and moisture vapor emission rate; install no flooring over concrete until the slabs have been cured and are sufficiently dry to achieve permanence with coating as determined by material manufacturer's recommended bond and moisture tests.
a. Effectively remove concrete laitance by steel shot blasting or method approved by flooring manufacturer.
b. Concrete slab shall have an efficient puncture-resistant reinforced moisture vapor barrier 10 mils thick minimum directly under the concrete slab (for slab on grade). Do not use vapor barrier manufactured with recycled material. Testing must be done to verify that the moisture vapor emission rate of the slab does not exceed that as recommended by the manufacturer at time of installation of the flooring or at any future date. Moisture vapor emission and moisture content testing must conform with the requirements of ASTM F-1869-98 (Calcium Chloride Test) and ASTM F-2170-02 (Relative Humidity Probe Test). If test results show excessive levels of moisture content or vapor emission rate, apply manufacturer’s recommended moisture vapor emission control material.
c. Treat cracks and non-expansion joints in concrete using manufacturer's recommended practice. Rout out crack/joint and fill with epoxy; reinforce with fiberglass cloth in accordance with manufacturer's recommendation to reduce cracking through flooring system.
A. Install all floor materials in strict conformance with manufacturer's instructions.
B. Prime entire surface with recommended primer.
C. Elastomeric membrane: Install to a minimum dry film thickness of 30 mils. Allow to cure.
D. Apply second coat of elastomeric membrane at minimum dry film thickness of 30 mils and broadcast aggregate to excess to achieve a minimum total thickness of 100 mils. Allow the floor to cure overnight. Sweep excess sand and vacuum, a light sanding or rubbing with a stone will aid in achieving a uniform "sanded" surface.
E. Apply aliphatic urethane grout and top coats to provide a uniform, dense surface.
F. Match finished work to approved samples, uniform in thickness, sheen, color, pattern and texture, and free from defects detrimental to appearance.
G. Apply temporary protection until floor is fully cured.
H. Integral Cove Base: Where scheduled, provide integral cove base formed from flooring over tile backerboard as specified under 09250 - Gypsum Drywall. Provide cove filler strips and trim strip at top of base as recommended by flooring manufacturer and trowel material up wall to form smooth, integral transition and base 4-6 inches high unless otherwise indicated or scheduled.
