Prime Adhere

Reliability - Seal It Once and Forget It

Product Description

Prime Adhere is a unique, multi-purpose, high-performance gunnable sealant that works under demanding conditions where other sealants fail. In damp settings where oil and/or water may be present, Prime Adhere will grip to the surface and retain its hold.

The specialized formulation of Prime Adhere makes it the perfect choice for sealing metal roofs and siding and, in the marine industry, for sealing such things as transoms, portholes and instrument panels.

Prime Adhere is designed to handle situations where movement and temperature variations are major factors. It is an excellent option for the permanent air-tight bonding of vapor barrier sheets used in roofing applications.

Prime Adhere remains permanently flexible. It expands and contracts with the sealed surfaces, never loses its adhesion and heals itself.

Rain or shine, hot or cold, any time of year, Prime Adhere outperforms the competition.

Seal it once and forget it. Take Prime Adhere, use it to seal your roof, siding or gutter job and then relax. Your task is finished. The seal will last. The bond will not break. The flexibility will not be lost. You needn’t worry any further. Enjoy peace of mind, secure in the knowledge the job’s well done.

Worries about temperature changes and inclement weather are a thing of the past. Prime Adhere is specially designed for use in demanding applications where movement and temperature are major factors. As you know all too well, surfaces like metal roofs expand and contract as temperatures rise and fall. Sooner or later, lesser sealants fail when faced with such conditions, but not Prime Adhere. Prime Adhere never loses its flexibility or its ability to heal itself. It stretches with the heat, contracts with the cold, and always heals itself, keeping your seal intact.

Prime Adhere sticks to damp and oily surfaces where other sealants fail. You can apply it when it’s raining and it still seals the job. You no longer have to depend on sealants that can only be applied when the weather decides to cooperate.

Prime Adhere labeling is available in English, Spanish, French, Chinese, Korean, Greek, Turkish, Ukrainian, Russian & Arabic.
