Do you recommend a coating of some kind to seal the tiles? I am getting some fine rubber dust inside of my table tennis ball machine. The balls pick up the rubber dust from the floor, and then it gets into the machine.

With our Eco-Lock Rubber Tiles and any of our rubber flooring, there is potential for a little flaking when first receiving your flooring. This is due to the making and cutting of the material at our production facility. We recommend cleaning the rubber flooring when receiving it. You will want to vacuum or sweep up any dirt and debris and then mop the flooring with a mild soap and water solution. There is still potential for some slight flaking; to help mitigate this, you can use our Rubber Floor Finish and Sealer. This will help to encapsulate any remaining material.
