Review on 🔒 GSSI Sealants Gray Butyl Tape Roll - 1/8" Thickness x 1" Width x 50' Length (Choose between 3/4" or 1" Width) by Phil Casey

I recently replaced a solid door with a single lightweight all glass door and used it in 5 strips over a level sill that was 1/2 inch by 3 feet was . It's very sticky and hard to adjust if you get it wrong the first time you place it, so don't make a mistake. Hold on to the backing paper until you're ready to install the door, period. Then slowly take it off, especially if you are installing on an old window sill, and use a plastic handle or something similar to hold the ledge as you need to. This material is fully sealed, no air, no insects and no jokes! I've used endless caulking pipe for many things during my construction life, but I know it's better than shooting caulking lines and hoping you don't drag it across the line when you install the door, creating a gap.
