## Description

Instead of the regular carpet joining this new Gel tape is quick and instant. No Iron needed. Ideal for carpet fitters doing a small join quickly. The gel tape will adhere to the underlay if required to give a more solid join. The seam tape is reinforced with a fibreglass. Comes on a 9 mtr roll and a standard 90mm wide tape with gel strip.

Review: Strooong! - Really strong hold! I fixed my carpet for my rental after my dog tore it up. The double sided tape is very easy to use and kept the new carpet down perfectly.
Review: This stuff sticks - Sticks down well. You have to cut quickly or else it starts sticking to scissors. I'm not a carpet pro, so I honestly don't know if scissors were the best tool anyways. Once you stick it down it is somewhat forgiving and flexible. But if you don't clean dust and debris from area it doesn't fully adhear. Rookie mistake, I guess. But luckily this is a huge roll, so any mistakes can be done over. Like I said, I'm not a carpet laying pro. Just a dog mom who came home to an unplanned home remodel, courtesy of my puppy. It has been a couple weeks and it's still holding down, and slowly (even after buying a seam roller) blending together. Not perfect, but did the trick. I would have to assume that if carpet installing or repair was a normal skill, for me, I would find this product to be good quality at a good price. Photos (for fun) of the culprit proud of himself and his older brother inspecting my handy repair work.
