I ran a test on two different seam sealing methods for a big job in a Tacoma office building
The spec called for hot melt tape on the main corridor, but I had some leftover cold adhesive from another project. I did a 20 foot section with each on the same type of carpet. After six months, the cold adhesive seam started to show a slight ridge when the light hit it just right, while the hot melt section was still flat. The building manager hasn't called about it, but I can see it. For high traffic commercial work, is hot melt tape just the better long term play, or did I maybe mess up the cold adhesive mix?
