Mule-Hide Products Co. Inc. launched its Seal-Fast Liqui-Flash polyurethane roofing sealant, which the company said seals complex details quickly and permanently.


Easy to use and providing excellent adhesion, elongation and tensile strength, Seal-Fast Liqui-Flash is an exceptionally versatile maintenance and repair solution, according to Mule-Hide.


The one-component, 100-percent solids, non-shrink, polyurethane sealant can be used in typical and difficult-to-access applications, including flashings, skylights, pitch pockets (filling and sealing), inlaid gutters, air conditioners, brick ties, roof vents, penetrations, ductwork, roof hatches, chimneys and seams, the company said.


It is compatible with a wide range of substrates, including metal, polyurethane foam, aged smooth asphalt, aged modified bitumen, aged PVC and aged EPDM, per Mule-Hide. 


It may be used on TPO roofing systems when primed with Mule-Hide Si TPO Primer. 


It is compatible with Mule-Hide Products acrylic and silicone roof coatings. 


It is an ideal choice for repairing hail-damaged polyurethane foam roofs, the company said. 


According to Mule-Hide, Seal-Fast Liqui-Flash goes on in one step using a brush or a ribbon nozzle; and requires minimal tooling but is viscous enough to prevent running and drain-out. 


It is semi-self-leveling, allowing it to be used for sealing and repairing single-ply membranes at any slope; fabric reinforcement is not required for repairs; and no stirring is needed, the compay said. 


Seal-Fast Liqui-Flash is available in three colors – black, white and gray. 


It is packaged in 10-ounce caulk tubes, 20-ounce sausage tubes, 1-gallon pails, and 3.5-gallon pails.
