What to use to fill gaps in underlayment?

Click-Lock vinyls need an expansion gap to expand and contract as a floating floor. Use shims or spacers along the perimeter walls. Do check your subfloor with a level. Lumps and dips are hard to see with the naked eye.

Does underlayment need expansion gap?

1. Improper spacing. To avoid buckling, subfloor panels should be spaced with a 1/8-inch gap at all edges and ends to provide room for naturally occurring expansion. Tongue-and-groove edges on many premium floor panels, such as Weyerhaeuser’s Edge Gold® OSB panels, are designed to self-gap.

How far apart should screws be on underlayment?

Never line up the underlayment seams with the subfloor seams; stagger the underlayment at least 2 inches with the subfloor seams. This adds to the stability of the floor and helps to defeat the broadcasting of lines through the resilient floors.

What kind of underlayment do I need for vinyl flooring?

The thinness and softness of sheet vinyl requires that it be installed on a surface that is very flat and smooth. Installing underlayment in the vinyl areas supplies the elevation, smoothness and levelness necessary for the proper installation of vinyl floors. One common underlayment for vinyl floors is 1/2-inch particle board.

Why is there a gap in my Vinyl flooring?

When moisture gets trapped under the flooring, like in the case of spilled water, it can weaken the vinyl’s integrity. If you glue the boards down, the moisture will weaken the glue and cause the boards to shift. If you use click-together or lose lay, the boards will shift in moisture as they slide around.

How big of a gap do you need for plywood underlayment?

Screws and nails may be spaced farther apart. Sheets can be butted together (just touching, not forced tightly together) or they can be gapped about 1/8 inch, or so. If they are gapped, usually the gaps must be filled with a seam filler.
