Our Paver Tiles - East Coast do have a rubber smell to them. The smell is not overpowering by any means, but it is there. The smell will not increase with temperature. There are no harmful vapors that are off-gassed by our rubber flooring. All of our rubber floorings are thoroughly cleaned and inspected for safety to ensure that a quality, low odor, safe product is delivered to you. If you would like a copy of the MSDS for this product, please feel free to reach out to one of our Flooring Heroes via chat, phone, or email, and they would be more than happy to assist you.
