We are looking to convert a room into a gym (this will be for the long term). We current have vinyl planking in the space and want to install rubber gym flooring. However we have done some research and have found that the rubber flooring can leach into the vinyl planking. We were thinking about possibly putting some Masonite Underlay in between the vinyl and rubber flooring. Do you believe this would work to protect the flooring? Any other suggestions?
