Plastic won't damage our carpets? A: We are SURE! Hundreds of millions of square feet of this product have been used over the past 30 years, and not once have we ever experienced this phenomenon. A word of caution though, we do recommend that all carpeting in an area where work is being done is covered. For instance, if drywall work is done, and only part of the carpet is covered, the carpeting left uncovered will almost always look lighter than the carpet that was covered, because of the drywall dust (and potentially paint overspray). Not all carpet protection films are created equal. There are imported products on the market, using solvent-based adhesive, that when not manufactured perfectly, will turn carpets permanently pink, green or orange.
