To ensure the lifetime waterproof properties of Revwood floors, the key aspect is to prevent any liquids from seeping underneath next to the walls. This is achieved by applying a silicone sealant along the perimeter to create a barrier. The RevWood Premier, Plus, and Select flooring options are designed to resist typical household spills, but when the planks are cut during installation, the protective layer is removed from the edges. Therefore, it becomes necessary to seal the perimeter with 100% silicone sealant to maintain the comprehensive waterproof RevWood warranty.
