Does SlabGasket shrink?

Vinyl products do shrink, and SlabGasket is no exception. We mitigate shrinkage by compressing the material in on itself as we install it. It also helps to leave it long over the ends some if possible. Shrinkage is not covered under warranty. If it does shrink a little, pull it up and stretch it out a bit, undoing some of the material compression from when it was installed.

Does SlabGasket discolor?

Yes. Tires can mark up the material by driving over it. The pigment in black mold can leech into the surface and it won’t come out. Weather can also alter the appearance. Discoloration of any kind is not covered under warranty. A lot of the discoloration can be pressure washed away.
