B. Do not begin work until concrete substrate has cured. Wood substrate should be dried to a maximum content of 12 percent. Metal substrate should be free of all rust and flaking material.
C. Beginning of installation means acceptance of existing substrate.
3.02 SUBSTRATE PREPARATION
A. Perform preparation and cleaning procedures in compliance with coating manufacturer's instructions for particular substrate conditions involved and as herein specified.
B. Clean substrate surface free of foreign matter; seal with Clear Acrylic Sealer where required.
C. 1. Concrete: Grind off all irregularities. Fill all hairline cracks with Patching Compound. Treat all moving cracks with 4” fiberglass mesh and 2 coats of Caulking Compound, as per manufacturer's instructions.
2. Plywood: Prepare wood joints with 4” fiberglass mat and two coats X-R Roof Coating. Install flashing and counter flashing as per plans. Apply two thin coats of All Deck Patching Compound to all metal, to cover nails, and to feather out, in accordance with manufacturer’s instructions.
3. Metal: Clean off all loose material. Spot prime all rusted areas with rust inhibiting primer. Reinforce all seams/joints in metal roof with 4” fiberglass mat and two coats of X-R Roof Coating.
