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 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.
