BT25XL Flashing Tape – Durable & Flexible Waterproof Window and Door Flashing Tape for House Wrap, Insulation, Construction Weatherproofing, Repair Applications – 4" x 75' Roll

This product sticks very well to concrete, unless the temperature is sub-freezing. While unconventional, I am using it along the inside of my crawl space and will attach the plastic sheeting to it - rather than running the plastic sheeting up to my sill plate. Using double-backed tape holds the plastic sheeting in place until I get everything in place and use pressure-treated wood slats to attach the plastic sheeting to the concrete - with this as a buffer. I will use butyl rubber sealant along the top to ensure moisture and insect control. I previously used this product on wood surrounding several windows, and found it very effective in that application as well.

We used this for a shed we built. We put it around the door and window openings and also put it over the small gap between the roof boards at the apex of the roof then put the tar paper and shingles over that. Working fantastic so far!

Doesn't stick great in cold weather (less than 50 degrees) but I used a heat gun when finishing out to make it stick.

Have used this for flashing around openings in the past......great product. Good quantity for a good price; was cheaper than local big box home improvement store........and delivered straight to my door (saving gas $$).

Used this item for a purpose that it wasn't really designed for but it worked very well for my project and I'm sure it would work very well when used for it's intended purpose.

Generally we love this product. We have ordered it previously and used it with great success. This time however, now that we are beginning to us it, we have found that there is no sticky substance on the back so when we go to place it on the wood that we want to protect it just lays there and can easily be blown away by the wind. I don't want to pay to have to return this, nor do I want to have to drive into town to get it to a UPS office, but we won't be able to use the product. I could go into town and buy a spray adhesive to make the product work, but the point of buying it was that we were depending on this product to stick just like it has done in the past. I ordered it early so that it would be on hand when we got ready to do our project and now we can’t use it. We need it now. Very disappointing.

Does not stick to house wrap! Even when it is 80+ outside, it sticks initially but will peel off within a couple of days to a week. Good thing I had a delay in stucco because this would cost me $1k's in call back for leaky windows. I used to use this all the time and it does stick good to OSB, or so I thought it did.

Worked great for my shed window installation.
