Should I use tongue and groove plywood for subfloor?

Tongue-and-groove plywood is superior to regular plywood for floor decks because it creates a stronger, more rigid subfloor, and helps eliminate sagging and “bounce” at the seams between the joists. But it is also more difficult to install because the tight-fitting joints don’t always go together easily.

Is tongue and groove best for subfloor?

Plus, tongue and groove will help force a more level floor. Leaks have no bearing on why they are used. If you have ever lived with a non-tongue/grove plywood (or chipboard) subfloor, the answer will be obvious: it is to prevent squeaking, creaking, and grinding from people walking over it.

What is the best material for a subfloor?

Plywood
Plywood is considered the most popular material used for subflooring, it has been used since the 1950s and remains one of the top choices for contractors. Standard plywood works perfectly fine as a subflooring material, but the best option is ¾” tongue-and-groove plywood subflooring.

Screw Spacing When installing subflooring, you will want to place the screws every 6-8 inches apart. This will allow some normal movement of the wood, while still keeping it nice and secure.

Can I use regular plywood for subfloor?

Standard plywood can be used for subfloors, but it is more common to use tongue-and-groove sheets that interlock along the edges. The recommended thickness of the plywood subfloor is governed by the spacing of the joists. The type of OSB used for subfloors generally is made with tongue-and-groove edges (T & G).

What thickness subfloor is recommended?

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.

What thickness of subfloor should I use?

The minimum thickness of plywood for subflooring is about 5/8 inch. Since it does not hold fasteners as well as plywood, OSB must be a little thicker, or at least 23/32 inch.

Can you waterproof subfloor?
