Hi. I just got Coretec flooring installed on the entire main level of our home; foyer, living room, dining room and kitchen. What kind of rugs/rug pads are safe to use with Coretec? I'm trying to find a couple of cotton rugs for the foyer, we live in Minnesota and in the winter months the rugs get very wet and dirty. I assume cotton rugs are fine. I know latex backing are not OK. Are rugs with a latex backing OK with the proper rug pad? I don't want any discoloration on my new floors. I'm also buying a 5x7 area rug for the living room and I'll need a rug pad for that, that is safe with Coretec. Any help would be appreciated. Thank you.
