Foundation Seal Tape (FST) is used to seal the vapor barrier to the foundation wall. When installed to a completely dry, clean (the concrete must be brushed off to remove loose debris- DO NOT USE A WIRE BRUSH- if the foundation is damp it will not stick well) foundation wall the bond is good enough to hold the vapor barrier to the wall temporarily (several hours/days) until the Foundation Pins are installed. If the foundation wall is wet in the area it will be installed and it will not bond then a polyurethane caulk must be used. This tape is 1.5" x 108' and has a reinforcement inside the tape to eliminate stretching like bubble gum. This is important because without the reinforcement this tape is impossible to apply in a crawl space. Most all other tapes on the market, similar to this one, do not have the reinforcement. 

Using a wire brush will create dust and debris that fills the pores of the block. When this happens the FST loses most of its grip to the block due to adhering to the dust in the pores rather than the block itself. No matter how much soft brushing you do AFTER the wire brush the FST will likely not stick. 

**During cold month installations this product must be stored indoors prior to use. This product is not meant for installations that have WET or very DAMP foundation walls please use the polyurethane caulk.

* Product Update- As of March 21, 2012 we have made several performance improvements to our Foundation Seal Tape™. 

First- We improved the formula in making our FST™, it now has 10x's the bonding power of our original FST™. Our original formula did a great job, but our new formula shows our continued efforts in research and our commitment to lead this industry by developing the most advanced products available.
Second- We improved the FST™ to adhere better to damp surfaces. Tests have shown the new formula can adhere to a "damp" surface, which is a major improvement. Since there are varying degrees of "damp" your results may vary. 
Third- We made the rolls lighter. When we increased the adhesion strength we were able to lighten the roll's weight and use less material. It created a balance between better performance and no increase in cost.
Fourth- We made it longer. Because we could make the rolls lighter it gave us the option to add some length to the roll, therefore making an even better value. The new roll size is 1.5" x 108' instead of 100' in the old formula.
Fifth- We work vary hard to make all of our products in the U.S. or Canada when possible. With some products it simply isn't, however the new FST™is now made in America. Investing in OUR country is as important to us as it is to you.

The new FST™ is in stock and ships immediately. 

**We always recommend getting a few tubes of Poly Caulk to make sure you have enough material to get a good seal to the foundation and to handle any damp areas on the foundation walls. Remember when you figure your FST to include going under beam pockets, ductwork that is touching the foundation walls and the access door. -\
6 rolls to a case.
