EternaBond EternaPrime Adhesive and Surface Conditioner Spray - 12.2 oz Can | EB-EPSPC | Aids in Adhesion on Dirty or Dusty Surfaces - for MicroSealant and Other Self Adhesive Seaming Tape

Worked as described! Easy to use, feels tacky/sticky when ready, holds up strong! Sprayed on the roof before using the tape and got a tight seal.

Did the trick. I used the cleaner and primer then the tape to go over existing caulking. There was some leaking before but I haven't detected any since the application. My rv is small with little storage space but will keep a bit in the rv in case there are new surprises. The product was easy to use. I was working with an 8ft strip. Be sure to leave the vinyl on the sticky sided until positioned correctly or you may get tangled and taped yourself! I had a few issues where it was difficult to pull the protective vinyl away from the adhesive but all seems to have worked out. I used this to reseal the front and back end caps. The back required an overlapping strip to cover the thickness of the prior caulking. The ladder seemed a bit shaky at the roof and the caulking appeared to be cracking to I used the tape there and the ladder seems to be much more stable now.

Impressive product! I HAVE BEEN STRUGGLING WITH HOLES & RIPS IN A RUBBER ROOF & FINALLY!! SOMETHING THAT WORKS!! I use this with the 6" INCH Eternaprime Tape and it WORKS. Make sure you clean your surface well first (I use mineral spirits, or another cleaning solvent to prep the surface) The manufacturers of this product has a spray cleaner but It is too expensive in my opinion and it is basically overpriced carburetor cleaner. In conclusion- the Eternabond tape and primer are EXPENSIVE but worth it.

preformed as advertised. any help making A side bond to B side is a plus in my book,,happy with product

Seems to work for the application intended.

Had a few tears in RV canvas roof and decided to use a primer spray to help tack up the surface since my canvas is so dirty. Clean your surface as best you can, then spray this primer on and ready in seconds to apply your butyl tape. It sprays easy and does not clog the spray button. Easy to use. I think this helps especially on canvas and surfaces. This name brand is WORTH it! Other brands are less reliable.

This spray really made my RV roof and sealant tacky. I bought it because I thought since I spent all the time cleaning and prepping this would help. I also did not want eternabond tape not to stick completely (the tape is incredible for adhesion already) on the old sealant.Well, I did 5 openings and then ran out of spray so I decided to just finish the job without spray around last stack pipe. The eternabond adhered well still and I have not had any issues BUT when I used the spray you literally could see the cracks in sealant imprint on tape! Even after several weeks in the sun and a camping trip the tape still shows the cracks underneath.Again the tape where I did not spray still adhered and seems to be sealed well but it is not as “stuck” as the areas where I sprayed first.

Unnecessary part of the application process. Waste of money and not able to return it even though it is unopened
