Should Floor Be Screwed Or Nailed To Subfloor

Although 5 8 inch is sufficient frequently 1 inch thick subfloor is installed.

Should floor be screwed or nailed to subfloor.

The preference is using a 3 8 plywood underlayment nailed or screwed over a plywood sub floor when gluing down a wood floor. Tongue and groove edges on many premium floor panels such as weyerhaeuser s edge gold osb panels are designed to self gap. Your nail screw rate is not as important as if you were attaching a new subfloor from scratch. This is more like strategic intervals to solidify the fastening.

Instead they just screw or nail the boards to the subfloor. It doesn t sound like you re reattaching the entire floor. This is fine if you re not worried about the long term durability of your work. Screws if driven properly prevent creaking floors.

To create a surface that will be strong and long lasting and that won t shift or peel up as the building shifts or moisture accumulates glue your underlayment down to create a more stable base. A screw firmly holds the subfloor in place which ensures a squeak less floor for years to come. If your home is suffering from squeaky floor syndrome you can remedy this issue by replacing the subfloor nails with screws instead. When gluing down to a plywood or osb sub floor many are tempted not to use an underlayment.

If you want to lay inch plywood as a subfloor or another inch flooring over a subfloor you should use an appropriate size of nail to ensure the flooring stays in place. Should the floor need to be repaired or replaced it is easier better with underlayment than with the subfloor. You re going through this effort to make it right. So do it right.

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. The subfloor is laid directly over the joists and is the true floor of the room. Glue and screw is popular for more reasons than just rhyming. You ll need to do this room by room.

Using subfloor screws to correct squeaky floors when subfloors are nailed in place the floor can become extra squeaky either almost immediately or over time.
