Basic Instructions For Adding New Subflooring Over Old Worn Out Subfloor - Home Remodeling Part 6
This video focuses on installing plywood or engineered lumber over existing diagonal one-by-six flooring in a home.
Greg discusses the reasons for doing this, including strengthening the floor and reducing drafts. He emphasizes the importance of using at least half-inch plywood and the need to break joints over floor joists.
We also provides tips on nailing patterns, screw usage, and the potential need for additional blocking or adhesives. The video includes several layout options for optimizing plywood usage and minimizing waste.
Another thing to consider is the importance of checking for floor flatness using a straight edge before installation.
Bonus Tips:
Consider using engineered lumber like OSB as an alternative to plywood.
If installing linoleum, use at least half-inch plywood to prevent buckling.
Break joints over floor joists whenever possible to ensure structural integrity.
Use screws in addition to nails for added security, especially around the perimeter and at joint breaks.
Install blocking or perimeter blocks for additional support and nailing points.
Check local building codes for specific requirements regarding joint breaks and fastening methods.
Plan the layout carefully to minimize waste and optimize plywood usage.
Use a straight edge to assess floor flatness before installation and address any significant imperfections.
Consider using adhesive in conjunction with nails or screws for added stability, especially for smaller pieces or in areas with weak subfloors.
