The recommended thickness of the plywood subfloor is governed by the spacing of the joists. Some experts suggest that 15/32-inch plywood should be standard if the underlying floor joists are spaced 16 inches apart or less, but slightly thicker 3/4-inch plywood should be used for joists spaced further apart.
Is it better to use OSB or plywood for subfloor?
This evolved plywood may claim an overall advantage over OSB, since plywood is a stiffer, longer-lasting subfloor option. It will also hold up better under flooring accidents like leaks or flooding, and has greater nail withdrawal strength to hold the nail in under stress.
How many layers of plywood do you need for a subfloor?
If you are using plywood for your subfloor, you should use a minimum of one layer that is between ¾” and ⅝” thick. This thickness will suffice for most floors; however, codes will vary and a second layer is a good idea if your floor covering is going to be a heavy material like ceramic tiles or natural stone.
How long does it take to replace a subfloor?
Replacing a small portion of the subfloor can be done in a day or two, but replacing an entire floor can take up to 24 hours. The finished floor needs to be removed first in order to replace the subfloor. It will be removed if there is an underlayment.
Should I screw or nail subfloor?
Using code-approved screws rather than nails is the best option for avoiding movement. If using nails for subfloor installation, stick with ring-shank nails; smooth nails may withdraw easier, leading to squeaks.
Should plywood underlayment be glued to subfloor?
Installing Plywood Underlayment
While underlayment traditionally was glued down to wood subflooring, most manufacturers today recommend installing it without glue, which greatly simplifies the installation. Thorough fastening of the underlayment panels is key to a successful installation.
What type of plywood is best for subfloor?
Plywood Subflooring
Plywood has been a standard subfloor material since the 1950s and remains the preferred subflooring for many builders. Standard plywood can be used for subfloors, but a better material is 3/4-inch tongue-and-groove plywood subflooring.
How much does it cost to hang plywood?
