Protective technique prevents damage to existing floors
Phase II purchases the 5-foot-wide foam, which is usually used under laminate flooring, in 300-foot rolls from a wholesaler. The foam costs 35 cents per linear foot.
The crew tapes the seams of the foam. On hardwood floors, carpenters install a layer of rosin paper under the foam to prevent moisture from seeping through to the floor. If there is a carpet, the carpenters overlap the protective film over the foam.
