From time to time we will receive an email from a a reader asking what to do if their mat curls up on the end or will not lay flat. There are a couple of reasons that this can happen and the cause may affect the suggested solution — that is our cover our rear way of saying you should check with the manufacturer and don’t blame us 🙂
Fan the mats out and get some air underneath them. Reposition the mats and make sure they have the proper expansion and contraction gap. Trim as necessary to make sure a full 1/2″ is left at the walls, posts and other solid objects. Also cut the mats 1/2″ short of the garage door.
If you are still having an issue use an acrylic floor tape or 3M #80 spray adhesive along the front edge where the ripples appear. It is possible the issue will migrate but general this will resolve the problem.
According to a recent article by an industry insider adhesive can be used over the entire floor as a last resort.
