How much of a rubber odor do these tiles have, and how long does it last?

Our 8mm Sport-Lock Rubber Tiles don't give off a lot of odor. They will have a rubber smell when you first receive them, and if you are sensitive to it, there are ways to help dissipate it. We recommend mopping the floor with a mild soap and water solution and then letting the flooring air dry. You will want to make sure that the space where the flooring is being installed has ample ventilation. You may have to repeat this process a few times to get the rubber smell to dissipate truly.
