Sealing the Perimeter and Transition Molding Expansion Gaps
Note: When working with silicone sealant, avoid getting it on the surface of the floor. Always wipe off excess sealant
completely and immediately.
• Obtain compressive PE foam backer rods and 100% silicone sealant.
• Place the backer rod in the expansion gap around the perimeter of the flooring.
• Cover the backer rod with silicone sealant. Ensure total coverage of the gap from edge to edge. There should be no gaps in
coverage.
• Repeat the same procedure for the gaps at transition moldings locations.
• At locations where the molding meets the floor surface, apply solid line of sealant between them.
• Fill all expansion gap between the floor and any fix objects such as pipes, cabinets, door frame, etc.
• Wipe off any excess sealant immediately.
Finishing Touches
• Clean the floor.
• Use matching putty where necessary
• Install or reinstall all wall trim pieces. Nail them through the wall, but not to the subfloor to avoid restricting the expansion gap.
• Install transition trim pieces. Nail them to the subfloor, not the flooring.
• At doorways, transitions should be used to protect the edges of the floor and to provide a decorative transition from one floor type
to another.
• If the floor is to be covered to prevent damage during construction, use a breathable material such as cardboard. Do not cover with
plastic.
