Liquid Rubber EPDM Primer 1 Quart 89600

This stuff is makes everything stick. It's amazing. I used it to seam a new EPDM KOI pond using seam tape. This stuff works crazy good. I am going to use it to seam my RV Skylight next.

After prepping my roof (scraping, rotory 3m disc, and lacquer thinner) removing the old sealant off the trailer roof, I applied the primer with a brush to the perimeter seam. This is a 6×12 trailer, I applied a 6" wide swath, then it tacked up slightly, so I applied a second coat to cover any deficiencies I may have left. Still have a half quart left. Material is very thin and easy to apply. The following day I laid down the seam tape, immediately followed by the top coat. Second coat of top added also a day or two later.

Product came unsealed and fully cured up could not use it at all

Très bon produit

Had to buy primer to ensure adhesion. Primer was great making a sticky surface. Coated around all vents. Cleaned and sanded the areas. Instructions said not to prime lap sealant. However i primes all areas to be sealed. Looks great and my newer roof will no longer have holes in the sealant. Priming adds an extra step.
