4. Can I use MULTIPLY® panels in a renovation?

Yes. The panels can be installed over the old existing vinyl flooring, provided it is free of any defects and structurally sound. If the old existing vinyl flooring does not meet these criteria, it must be stripped off by a professional. Holes or slits should be made in the existing vinyl so that moisture or vapor can’t be trapped.
