Step 1: Measurement and Layout

Before you begin, measure the area where you intend to install the plywood. Ensure your measurements are precise to minimize waste. Mark the layout of the sheets, keeping in mind the tongue and groove orientation.

Step 2: Safety Gear

It’s crucial to wear safety gear. Always use safety glasses, gloves, and a dust mask to protect yourself from any potential hazards during cutting and installation.
