The picture shows 2 rolls and the description says 15 ft each are there 2 rolls equaling 30 ft?

Thanks for you interest in American made Second Skin butyl products. The main default picture is the product picture which shows the actual product packaging and the single roll for this offer. The second picture is just a product display picture that shows rolls at different angles so you can better see the product thickness. We do sell the product in a 3 roll package on Amazon if you need multiple rolls.

Can i use this to adhere a poly vapor barrier to a concrete block foundation? also does it hold up over time? crawl space encapsulation project ...

It does hold up over time in the temperature range of -40 to 200 degrees F. And it will adhere to poly vapor barriers and concrete. It will not harden over time; it will remain viscoelastic and adhered.

how is it?Does it work well?

I like it. Multipurpose for sure. I used it to attach brake lights to my backhoe maybe 6 months ago. Still stuck on there. You will find other uses for it.

What is recommended cleaner to prep for installation

We recommend cleaning all surfaces of debris and then wiping down with denatured alcohol before applying.
