Rooms/Areas Susceptible to Moisture
The following recommendations will help to make sure your laminate flooring installation is successful in rooms prone to moisture.
Kitchen and Bath
Do not install cabinets on top of laminate flooring. Laminate flooring should be installed up to the front of the cabinets leaving a ¼ to ½ inch expansion space. Silicone sealant should be used to fill-in expansion space in all possible wet areas such as icemakers, dishwashers and sink areas.
Make sure that rubber pads are attached to the washer and dryer leveling feet before these appliances are operated.
Always use transitions and silicone sealant at bathroom doorways to separate the bathroom flooring from the remainder of the installation. Toilets must be removed before installing laminate flooring. Leave a ¼ to ½ inch expansion gap around the toilet flange perimeter. After fitting of the flooring this gap should be sealed with premium quality silicone sealant. Seal with silicone sealant the expansion space around the room perimeter and all fixed obstacles such as cabinets, pipes, doorframes, sinks and toilets. To avoid water penetration underneath the planks in any wet areas, you must seal with silicone sealant the expansion space around the perimeter. (This will not affect the expansion of the laminate flooring.)
If installing over concrete or a concrete floor covered by tiles, you must first lay down a 6-mil plastic sheet vapor barrier. Always apply a small bead of silicone sealant between the bottoms of the trim molding and the surface of the laminate flooring.
Do not install laminate flooring in rooms with a water drain located in the subfloor. For moisture resistance warranty in any room, silicone sealant must be used as instructed in all of the above instructions.
