This product being 4 inches wide is great. This tape is extremely sticky, sometimes I thought it was not coming off my fingers.



Great product

This product is great stuff. it is super sticky and as long as you follow their directions it will really stick to concrete of cinder blocks good.



Some rimes it was so sticky is was hard to get it off my fingers.



Great product.

moved into a home that has a crawlspace that sat for about a year in the humid east coast summer heat. then some into the fall. layed down the 20mil vapor barrier ..immediately the next day after 90-95% of the earth under was covered , not even done taping and still some small spots exposed.. the foundation had begun to dry. even parts of the house were joist had significant and visible moisture it quickly started to dry. Havent used my moisture meter on the sub flooring yet( which is visible due to putting down new hardwood) but according to my thermometer which has a RH reading. it went from anywhere from 55-70 % ( before vapor barrier) to right around 45-35 % ( after installation of vapor barrier) . The Vapor barrier feels and looks like true 20mil. I have yet to see a better product around. Highly recommend to anyone looking to encapsulate or just have some added protection from moisture in there crawlspace. !

great product, very durable.

easy to use, durable product
