How strong is the odor and how long after installation before it is no longer noticeable? Is there any way to expedite the out-gasing? Thanks.

Our 3/8" Sport-Lock Rubber Tiles do have a mild rubber smell associated with them. This smell, on it's own, will dissipate after a few weeks of installation. To help speed up this process, we recommend mopping the floor with a mild soap and water solution and letting the floor air dry. This step may need to be repeated for people who are sensitive to smells.
