Technical Specifications
DESCRIPTION
Duck Coat is a white, highly elastomeric, thermoplastic rubber coating that provides a
waterproof sealant over at roofs. Duck Coat is formulated to hold up to ponding water
conditions on at roofs. Duck Coat can be installed on most roong substrates including Built-
Up Roong (BUR), Metal, Concrete, EPDM Rubber, TPO, APP, Modied Bitumen, Polyurethane
Foam, PVC, Asphalt, Wood and more. Duck Coat can be applied in cooler temperatures as
low as 35 ºF. Duck Coat helps extend the life of the roof and reduce building energy costs by
increasing solar reectance. Wet, freshly applied Duck Coat will not wash off even if rain occurs
immediately after application.
IMPORTANT
Bleed-through may occur when applying Duck Coat over asphalt or coal tar roofs, resulting in
a brownish color. Perform a small test patch rst to check for bleed-through. If bleed-through
occurs, additional coat(s) may be required to eliminate discoloration from bleed-through.
APPLICATION
For Non-Single Ply Rubber Roof Surfaces (i.e. Built-up, metal, asphalt, concrete,
Polyurethane, etc.)
Stir Duck Coat thoroughly before and during application. DO NOT THIN. Clean surfaces
thoroughly by brooming away dirt, debris, and loose particulate. Broom away excess water and
allow roof surface to dry. Duck Coat can be applied by brush, roller or spray. Apply at a rate
of 70 square feet per gallon per coat. Two coats are recommended for optimum performance.
Allow Duck Coat to dry thoroughly between coats. Airless spray equipment shall be capable
of producing 3,000 psi and 1 gallon per minute capacity. Recommended spray tip size is .025
to .035. Dry time of coating is dependent upon temperature (warmer temperature will result in
faster dry time). Typical dry time is 2-4 hours. Typical re-coat time is 4-10 hours. Brush should
be quality synthetic. Roller should be long nap for solvent based coatings.
For Single Ply Rubber Roof Membranes (EPDM, TPO, HYPALON)
Stir Duck Coat thoroughly before and during application. DO NOT THIN. Power wash and scrub
with broom to remove dirt and grime and rinse well. Let dry 24 hours. The following three-
step application process is designed to minimize swelling and deformation of the rubber roof
membrane as the solvent “bites” into the rubber membrane.
• Using a 9” double supported roller, apply a thin prime coat of Duck Coat at a rate of .5
gallon per 100 square (you should still be able to see some of the membrane showing
through.) Allow prime coat to cure for at least 4-6 hours or until dry to the touch.
• Apply a second coat of Duck Coat at a rate of 1 gallon per 100 square feet and
allow to dry.
• Apply a third coat of Duck Coat at a rate of 1 gallon per 100 square feet and
allow to dry.
NOTE: Duck Coat may be applied to single ply rubber roofs by contractors with experience in
spraying solvent based roof coatings in thin layers.
IMPORTANT: DO NOT OVER APPLY DUCK COAT AS THIS MAY RESULT IN EXCESSIVE
WRINKLING OR BUCKLING OF THE RUBBER MEMBRANE. DO NOT POUR DUCK COAT
DIRECTLY FROM PAIL ONTO RUBBER ROOF AS THIS COULD WRINKLE MEMBRANE.
POUR DUCK COAT INTO A PAN AND APPLY BY ROLLER AT RECOMMENDED COVERAGE
RATE. SPRAY APPLICATION IS ACCEPTABLE BY EXPERIENCED CONTRACTORS.
COVERAGE
• Non-single ply rubber roof membranes (i.e. Built-up, metal, asphalt, concrete,
Polyurethane, etc.): One 4.75 gallon pail will provide enough material for
2 coats over an area of approximately 175-200 square feet.
• For single ply rubber roof membranes (i.e. EPDM, TPO, Hypalon): One 4.75
gallon pail will provide enough material for 1 primer coat and 2 coats over
an area of approximately 135-150 square feet.
