A liquid-applied, single-component, moisture-cured polyurethane membrane. ELASTO-DECK™ 5500 is widely used to waterproof concrete and plywood decks which are subsequently covered with outdoor carpeting, tiles set in thin-set mortar, or wood decking. The product is also recommended for all applications which require the waterproof surface to be painted, where a bitumen-extended polyurethane would not be suitable.
BASIC USES:
May be used under thin-set mortar or mortar bed tile installations. ELASTO-DECK™ 5500 is also available in a special thixotropic consistency for use over irregular surfaces such as foam roofs, in which case, it must be coated with ELASTO-GLAZE™ 6001 AL.
SURFACE PREPARATION:
All surfaces which are to be waterproofed with ELASTO-DECK™ 5500 must be free of contamination such as curing compounds, concrete hardeners, bond breakers, paints, etc. All surfaces must be dry, having a maximum water content of 20%. We recommend water-curing concrete instead of using concrete curing compounds. Only exterior grade plywood (5/8" (1.59 mm) minimum thickness) should be used. Concrete should be cleaned by sandblasting or acid-etching. After acid etching, allow a minimum drying time of 72 hours. Except for non-moving shrinkage cracks, all other cracks and joints must be sealed with ELASTO-THANE™ 230, a single-component, moisture-cured sealant manufactured by Pacific Polymers, Inc. All surfaces, where necessary, must be primed with ELASTO-DECK™ PRIMER prior to application of the coating system at a rate of 300-350 square feet per gallon (7.35-8.58 m2/liter), except for plywood in good condition.
All seams between plywood sheets, and those between metal flashing and the plywood deck, must be reinforced by embedding a 2 inch (5 cm) wide strip of glass cloth tape into wet ELASTO-DECK™ 5500, which is brushed evenly over the seam to a width of about 3 inches (7.6 cm) and a thickness of about 10 wet mils.
The application of ELASTO-DECK™ 5500 can subsequently be made immediately over the entire area, including the taped areas. Cracks in concrete must be treated in the same way. Where ELASTO-DECK™ 5500 is used as a protective coating on polyurethane foam roofs, it must be applied within 8 hours from the time the foam is installed. ELASTO-GLAZE™ 6001 AL must be applied over the ELASTO-DECK™ 5500 where exposed to direct sunlight.
