Product Description

This product is made of a super tacky butyl rubber that sticks well to most masonry surfaces and also polyethylene.  Being a two sided tape, this will allow you to mount objects on vertical surfaces and will also create a seal.  In some situations it can be used as an alternative to using nails and washers or screws to mechanically fasten the polyethylene liner or rigid foam insulation (such as our Bora-Foam).  At the same time, it can serve the purpose of sealing the liner or insulation board to the wall and eliminating the need for caulking.

Directions for attaching polyethylene or Bora-Foam to a wall or pier:First you need to firmly apply the tape to the masonry surface.  Then pull the paper backing carefully off by pulling alongside of the wall (as opposed to away from the wall).  Finally, apply the top edge of your liner (or foam board) to the face of the tape.  You now have fastened the liner (or foam board) to the wall and also created a seal.

  1. Great tape for cinder block 4 Star Review

    Posted by on 23rd Aug 2018

    We tested this tape in two crawl spaces. This stuff sticks like crazy to cinder block walls. It sticks to the plastic well too. We were using 8 mil poly.

    We had trouble getting it to perform well on brick. It seems the uneven surface of the single brick stem walls gives us trouble - especially when encountering an adjacent pier.

    One tip that everyone needs to know is that it works best if you brush any dust and debris from the concrete surface before you apply it. Just a quick brush will do. And it seems to work best if you let it sit on the wall for a few minutes before pulling the cover off of the front facing side.


  2. Sticky but excellent product 5 Star Review

    Posted by on 10th May 2018

    Very, very sticky stuff. If carefully placed, it's great for sticking plastic vapor barriers on walls. Much better than using acoustic sealant and making a mess everywhere.


  3. Great liner holder 5 Star Review

    Posted by on 2nd Apr 2018

    Used the butyl tape and sealing tape to hold the liner, make sure you clean the wall area where you plan to stick the liner first before applying the butyl sealing tape for best results.


  4. Worked as intended 5 Star Review

    Posted by on 12th Jan 2018

    I purchased this tape to use in encapsulating part of my crawlspace. It worked great but you really have to make sure your block is completely clean and dust free. I brushed with a wire brush everywhere the tape was going to go but there were a couple spots where I did not get all the dust off and it didn't stick as well in those spots. My fault entirely.


    The plastic vapor barrier stuck to the tape very well, as in it is never going to come loose from it. Make sure you have it the way you want it before sticking the plastic to the tape.

    I also purchased some the plastic Christmas tree fasteners to use on this project. I had the bright idea to drill through the double sided tape and use the fasteners to help hold it in place. Not such a good idea after all! The tape is sooooo sticky that it wrapped around the drill bit and made a huge mess. I know better now. :-)


  5. Holds the poly 4 Star Review

    Posted by on 13th Aug 2017

    Had to apply the tape to the poly first and not to the concrete bock. Pulled away from the block when I pealed off the backing! Then it held the poly to the wall just fine.


  6. Works as advertised 5 Star Review

    Posted by on 15th Jun 2017

    I am very impressed with this product. Seems to work exactly as described. I am ordering more now.


  7. good size and it works 5 Star Review

    Posted by on 21st May 2017

    I was looking to start large crawlspace encapsulation project as a 1-man job.
    My first challenge was finding materials at the right price since there is a lot of competition for DIYers. The second challenge was securing my wall vapor barrier since I have a combination of real brick, concrete block and foam board insulation. This product was selected after looking at several YouTube videos on technique and it worked for me. Best price for the width of the tape too - so will probably work for you too.


  8. Excellent quality 5 Star Review

    Posted by on 27th Apr 2017

    This does exactly what it should do - highly recommend. Quick shipment and great product.


  9. Excellent sealing qualities 5 Star Review

    Posted by on 5th Dec 2016

    This double sided tape sticks to masonry, foam board and polyethylene creating a secure seal. Very neat to work with.


  10. Good product 4 Star Review

    Posted by on 14th Oct 2016

    Seems to work just fine , only time will tell if it has staying power over time , make sure walls or any surface is dry before you apply it.
