• Surfaces should be clean, dry and free of dirt, oil and any foreign matter.
• DP 1030 should be applied to all connections according to SMACNA standards. Brush, caulk, pump, or trowel DP 1030 on all duct seams. Apply to TDC/TDF and applied flange corners. Apply to all penetrations in the duct wall including sheet metal screw heads and tie rods. When caulking DP 1030, sealant should be brushed into seams.
• Apply DP 1030 to the male section of the fitting or to the inside slip duct coupling. Secure with sheet metal screws per manufacturers requirements. Apply a 2" band of DP 1030 around outside of joint, covering all screws.
• Assemble sections according to the manufacturers recommendations. Apply a 3" by 20 mil band of DP 1030 to the joint. Embed a fiberglass scrim (5 mil, 20 x 10 plain weave, 1.75 oz per sq. yd.) in the sealant and apply another 20 mil coat of DP 1030 over the scrim.
• Install flexible duct per manufacturers instructions using drawbands or mechanical fastener. Apply DP 1030 at a rate of 80-90 sq. ft. per gallon (20-40 mils) between the end of the duct and the collar in a 2" band. Use DP 1030 to seal all connections of collar to metal duct or rigid fiberglass ductboard.
• Allow at least 48 hours before pressure testing. Since temperature and humidity conditions may vary, longer cure times may be required for specific installations.
• Dependent on application thickness, 80-90 sq. ft. at 20-40 wet mils
• Use warm water and soap.
