PART 3 - EXECUTION

3.01 INSPECTION

A.       Plywood

1. All plywood to be coated shall carry the grade trademark of APA Exterior AC or better.
2. Plywood substrate shall be a minimum of 5/8" thick, laid over joists on 16" centers and secured at all edges with screws, ring shank nails or equivalent non-backing nails.
3. Plywood surface should be clean and dry, free from voids or loose particles.
4. Plywood shall be protected from moisture to prevent weathering and delamination of the substrate. A protective construction coat of Excel-Coat #1 may be applied to the plywood substrate at a rate of 75 square feet per gallon. Do not apply non Excel-Coat protective sealers, varnishes, water repellent coatings or hot mops without prior written approval from Excellent Coatings. Inc.
5. Plywood substrate shall be designed and constructed as to freely drain and eliminate the ponding of water.  Slope: 1/4" per foot.

NOTE:        Oriented Strand Board (OSB) is not recommended for use with Excel-Coat Waterproofing Systems.

B.       Metal Flashing

1. Metal flashing shall have a bonderized finish (etched and galvanized) and be a minimum 26 gauge. 
2. Metal flashing must be installed in accordance with acceptable waterproofing techniques as indicated on Excel-Coat Fire System detail drawings.
3. Metal flashing shall be fastened 3" on center in a W pattern with galvanized metal, non-backing nails. Flashing must be nailed down flat with no buckling.
4. All metal flashing must have a 3" overlap at the connecting seams. Corners must be tight and the entire perimeter must be flashed.  Overlap shall be treated with a 4" strip of fiberglass or deck seal tape, saturated with one coat of Excel-Coat #1.

6. Metal must be clean and dry prior to application (free from grease, oils, dirt and debris).

3.02 INSTALLATION

A.       Read Excel-Coat Fire System Application Guide prior to installation process.

1. Apply Excel-Crete underlayment with trowel to minimum 1/4" depth. Allow material to cure approximately 24 hours. Dry times may vary.
2. Water test:  Water test underlayment to ensure water slopes to drain.  Ponding or low spots may be picked up by applying additional Excel-Crete material.  Excel-Crete may be applied up to 1 inch lift per application and feathered to an edge. 
3. Cover surface with fiberglass mat and saturate mat with Excel-Coat #1 at a rate of 50 square feet per gallon. Allow material to dry approximately 6-8 hours. Dry times may vary.
4. Apply skid resistant texture coat (Excel-Coat #200 or Excel-Crete K/D and Excel-Crete Tinted Additive) at a rate of 75 square feet per gallon. Allow material to dry approximately 6-8 hours. Dry times may vary.
5. Apply two thin coats of Excel-Coat #300 by roller or airless sprayer at the rate of 250 sq. ft. per gallon per coat, for a net yield of 125 sq. ft. per gallon total coverage.  Allow material to dry approximately 6-8 hours. Dry times may vary. 
6. Allow completed system to cure 24 hours before heavy foot traffic is permitted and an additional 72 hours before heavy objects are placed on the surface.
