EternaBond RSW-4-50 RoofSeal Sealant Tape, White-4" x 50'

EternaBond RSW-4-50 RoofSeal Sealant Tape, White-4" x 50'

Q: Can this product be coated/covered with the Liquid Roof EPDM product?

My seams on my Motorhome were sealed with this product 10 yrs ago. My roof was recoated with EPDM rubber roof in a bucket three years ago. No problem thus far.

Q: Has anyone used this on galvanized metal roofing? Lots of seams!! Some have been caulked with silicone..

I used this sealant on a galvanized camper roof at the numerous seams that were previously coated with silicone. I made sure that I centered the silicone with the sealant. I was worried but took the chance that there would not be a reaction between the two products. it has been two years now and the roof is still fine

Q: What size is the roll of tape

The tape is 4 inches wide by 50 feet long. There are three sizes to choose from, 2" x 50' long, 4" x 50' long or 6 inches wide by 50 feet long. It's designated on the packaging as 2-50, 4-50 and 6-50. Works great. You can put it on and done! When you use lap sealants by Dicor or other makers they take up to a month to fully cure.

Q: Would this be good for a large mobile home roof ?

I think it would be good to use on any camper or mobile home roof to help stop a leak, especially at a seam, but it would also be a good idea to seal around the edges of the EternaBond with a bead of DiCor sealant. That's what I did on my aluminum camper roof and it worked like a charm.
