Slope is a function of structural design, and the GacoDeck Kit cannot be used to provide such a slope where it does not already exist. A deck that lacks adequate slope may experience leaks at low thresholds, standing puddles, or surface stains from ponded water and debris. Avoid soiling the fascia by incorporating a gutter or drain into your design. Insert drain flush with plywood. Install a positive drip so that drainage is outside the fascia.
Good design requires that adequate ventilation be provided for the deck structure.
Drive nails flush without indenting plywood. Concrete Concrete surfaces to receive GacoDeck Kit must be structural concrete which is properly ventilated. Concrete must cure and dry four weeks before GacoDeck Kit application. Concrete surface should be smooth and free from rock pockets or voids without being burnished. Etching of concrete is not normally required.
