Grip Strip is chemically inert closed-cell polyethylene that is shaped to fit between log courses to form a flat surface for the application of Perma-Chink or Energy Seal. This makes it easier to maintain a consistent thickness of sealant across the seam, reducing the amount of sealant required and improving the sealant’s performance.
- Provides a firm chinking or caulking surface
- Shape and texture allow it to be easily installed without using staples, nails or glue
- Repels water
- Compatible with all commonly available synthetic chinking
- Helps prevent blistering of chinking surfaces
- Provides extra insulation against heat loss
- R-value for Grip Strip: 1.2 for 2.5″ & up; .9 for 1.25″-2″; and .6 for 1″ & under

Your questions about Spatulas & Trowels answered.
Do I need to use backing material?
Yes. For proper adhesion and elasticity of sealants, backing materials should be used. Read more here.
Can I use any foam for backing?
No. The wrong foam, like pink or blue colored foam, will “out-gas” and cause blisters in sealants. Read more here.
How do I smooth out my sealant?
For a smooth finish, spray the sealant with water and smooth it using a metal spatula. You can learn more about the process of tooling here.
