I was looking into this to cover up some synthetic ice in my backyard. I live in Las Vegas, where it can be continually up to 120 for days. Will the Rubber melt or create marks on the synthetic ice and withstand that much heat without being warped or cracked?

Our 1/4" Pre Cut Tough Rubber Rolls are made from recycled commercial truck tire tread. If your tires can handle the heat, our flooring will too. Our rubber flooring has been installed all over the US and Canada in some of the most extreme conditions. Our rubber flooring will not crack or warp due to the conditions. Now, that doesn't mean our rubber flooring won't expand and contract. All flooring, to an extent, will do this as these materials have a basis in natural products. So, if there are major temperature changes, there will be some expansion and contraction of your floor. You can install these as a protectant over your synthetic ice without our rubber flooring damaging it. If you are concerned that the flooring may leave marks, we recommend placing a plastic sheet between the existing surface and our rubber flooring. This sheet will ensure that no staining will occur.
