Can I cover my hardwood flooring with this?

Yes, you may, as long as your hardwood flooring is indoors, which we think it must be. However, please note that this turf is porous, so if water is spilled on the turf, it will pass onto the hardwood floor underneath. When used indoors, it is ideal to install these without glue, so you may either loose lay them or use a double-sided tape along the perimeter to hold the turf in place.
