The product stuck very well to the 125 year old soft bricks in my crawlspace. I just dusted the bricks with a paper towel and had no problem with adhesion.

Just wanted to send you a quick note to let you know how well the Foundation Seal Tape worked for my vapor barrier. After brushing the block and insuring they were dry, the tape stuck well and allowed me plenty of time to hang the vapor barrier and install the Foundation Pins. This barrier has been installed for a month now and I have had no problems with the seal. I would recommend the Foundation Seal Tape and Foundation Pins to anyone who is installing a crawl space vapor barrier.

Tape is by far better then any other type tapes on the market. Seal is incredibly tight. Looks professional when in stalled correctly. Highly recommend this product.

 

These pins are very good quality and are holding my vapor barrier firmly to the wall.
