Installation and Handling in Wet Areas

Working with Mgo Board

You can install mgo board as a subfloor in wet areas with confidence. The process is simple and helps you avoid problems with moisture. Mgo board does not absorb water, so you get a strong base for your floor. You should follow these steps for a successful installation:

1. Measure and cut the mgo board to fit your subfloor layout. Make sure the edges are clean for tight seams.

2. Place the mgo board on the joists. Secure each panel with special screws. Space the screws 8 to 12 inches apart for a solid hold.

3. Leave a small gap of 3 to 5 millimeters between each mgo board. This gap lets the panels expand or contract with changes in temperature or humidity.

4. Check the surface with a level. Adjust the mgo board if needed. You can add vinyl, tile, or hardwood on top of the mgo board for a finished look.

You will find that mgo board is easy to handle. The panels are light and strong. You do not need special tools for installation. Mgo board gives you a safe and long-lasting subfloor in wet rooms. You can trust mgo board to keep your floor dry and free from mold.
