Replacing or installing a new floor in a mobile home requires choosing the right size and type of plywood to ensure stability, durability, and long-term performance. Mobile homes have specific flooring needs due to their structure and mobility, making it important to select plywood that can handle daily wear and environmental changes. This guide will help you understand the best plywood sizes for mobile home floors and how to choose the right material for your project.
What Is the Standard Plywood Size for Mobile Home Floors?
The most commonly used plywood thickness for mobile home floors is 5/8-inch or 3/4-inch. These thicknesses provide sufficient strength and support for everyday use. For subfloors, 3/4-inch tongue-and-groove plywood is often recommended due to its ability to lock together tightly, reducing movement and adding extra stability.
Tools and Materials Needed for Installation:
1: Measuring and Cutting Tools
A measuring tape is essential for accurate cuts, ensuring the plywood fits the space perfectly. A circular saw or jigsaw is necessary to cut the plywood to the correct dimensions.

2: Adhesives and Fasteners
Use construction adhesive or subfloor glue to secure the plywood firmly to the joists. Screws or nails will provide additional stability by fastening the plywood securely in place.
3: Moisture Protection
Consider using a moisture barrier or underlayment to protect the plywood from potential moisture damage. This step is especially important in areas with high humidity.
Step-by-Step Guide to Installing Plywood in a Mobile Home:
Step 1: Prepare the Subfloor
Remove any old flooring and inspect the subfloor for damage. Repair any soft spots or damaged joists before laying new plywood.
Step 2: Measure and Cut Plywood
Measure the floor area and cut the plywood sheets to fit using a circular saw. Ensure accurate cuts to minimize gaps.
Step 3: Lay Down the Plywood
Apply construction adhesive to the joists and carefully position the plywood sheets. Leave a small gap between sheets for expansion.
Step 4: Secure the Plywood
Fasten the plywood to the joists using screws or nails. Space fasteners every 6 to 8 inches along the edges and every 12 inches in the center.
Step 5: Seal and Finish
Seal the joints and edges with a wood sealer or caulk to prevent moisture from seeping in. Install your chosen flooring material over the plywood.
