PREPARATION

1.        All plywood shall be a minimum of 5/8" thick, exterior grade, AC or better, plugged and filled.

2.        Check all joints. All edges must be blocked and supported. Plywood shall be fastened with deck screws or nailed with ring shank or equivalent non-backing nails in accordance with Local Building Code.

3.        Check for proper slope: 1/4" per foot.

4.     Check for imperfections and damage to the substrate, perimeter building materials, and substrate joists and beams.

Note:       If the plywood will be exposed for extended periods of weathering, it is recommended that the plywood surfaces be initially treated with a coat of Excel-Coat #1. This will aid in preventing delamination, deterioration or warping.

Excel-Coat Waterproofing Systems can be installed over other waterproofing systems.  Contact an Excellent Coatings representative to find out what options are available for your particular application.

1.        Metal flashing shall have a bonderized finish (etched and galvanized) and be a minimum 26 gauge. 2.        It is recommended that a bed of caulk be placed on the plywood and the metal flashing seated into the caulk. 3.        Metal flashing shall be fastened three inches on center in a W pattern with galvanized flashing nails.  Flashing must be nailed down flat with no buckling. 4.        All metal flashing must have a minimum 3" overlap at the connecting seams.  Corners must be tight and the entire perimeter must be flashed.  Overlaps shall be treated with a 4" strip of fiberglass saturated with Excel-Coat #1.  Soldering of overlap is also acceptable. 5.        All joints and seams shall be caulked with a urethane sealant.  Remove all excess sealant from the plywood and flashing.

Stair nosing is recommended on all stairs and landings to minimize wear.  The stair nosing should be installed before the Excel-Coat membrane is installed.  For proper drainage, the nosing should be 1"-2" shorter than the step, and centered, allowing a gap on either side of nosing to allow water to drain off the stair.

APPLICATION

The entire deck surface should be covered with the 2.5 galvanized metal lath.  Lath shall be installed over horizontal edge of all metal flashing.  All seams in the lath shall be tight, with no gaps or overlap. PREPARATION:

1.        Pull sheets of metal lath off the bundle in the same direction and lay side by side. 2.        Seams in the metal lath must be a minimum of 3" away from a parallel joint in the plywood. 3.        Using a few galvanized roofing nails, fasten the lath in place to prevent the metal lath from moving while stapling.

APPLICATION:

1.        Using a 16 gauge, minimum 1" crown and minimum 5/8" leg galvanized staple, begin to staple in the middle of the sheet and work toward the edges.  2.        Staple in a checker pattern using approximately 20-25 staples per square foot. 3.        Adjust next sheet and repeat process.

4.        After all sheets have been fastened, staple all seams at a rate of one staple per linear inch.  Use galvanized roofing nails in any areas where the staple gun will not reach or hold lath back ½ inch from angles and edges to ensure all outside
