Deck Flex W.M. Waterproofing System

All surfaces must be free of contamination such as water, curing compounds, hardeners, bond breakers, paint, etc. Substrates must be structurally sound, free of any projections or depressions. Preparation is a critical part of the application process. Edges should use flashing and protected properly. This system is particularly well suited for plywood deck waterproofing.

Step 1
Apply 2.5lb per square yard metal lath using 1" crown by 5/8 inch long staples generously over entire surface without any overlapping metal lath edges. Staple at a rate of ~22 staples per square foot.

Step 2
Deck Flex TetraCrete mixture of 45-50 pounds of TetraCrete #2 (TC3 Grey) and one gallon of TetraCrete Additive shall be troweled down onto metal lath at the rate of 70-85 square feet per gallon. Dry time 2-3 hours depending on weather. Minimum thickness 1/16" with no metal lath visible.

Step 3
Fiberglass mat 3/4" oz per square foot 50" wide shall cut to fit the area to be coated.

Step 4
Deck Flex Base Coat shall be rolled and brushed (corners) over the fiberglass material at the rate of 60-75 square feet per gallon. Dry time 2-4 hours depending on weather. Dry thickness 1/16".

Step 5
Deck Flex TetraCrete mixture of 45-50 pounds of TetraCrete #2 (TC2) and one gallon of TetraCrete Additive shall be spray applied for texture coat onto the cured Deck Flex Base Coat at the rate of 70-85 square feet per gallon. Dry time 2-3 hours depending on weather.

Step 6
Deck Flex Top Coat shall be applied by rolling or brushing onto entire cured texture coated surface at the rate of 150-180 square feet per gallon. Apply two full coats. Dry time 1 hour or less depending on weather.
