Think Your Floor Is Waterproof? Probably Not

Even newly sealed gym floors are not really waterproof.  The finish may look impenetrable, but that is rarely the case.

Because each piece of wood in a hardwood floor expands and contracts at a slightly different rate, microscopic cracks in the floor finish quickly open up.

These are not usually visible to the naked eye, but they offer opportunities for liquids to penetrate the floor surface so that they can be absorbed into the wood.

That is why it is important to quickly clean up any spills-water, sweat, whatever-that you may have on your floor.

Use a non-abrasive cloth or soft mop to get up the liquid and then make sure that the surface is completely dry.
