Mold and Swelling Issues

You need to think about mold and swelling when picking a substrate floor. Mgo boards resist mold because they do not give mold spores any food. The inorganic makeup of mgo boards means mold cannot grow. Tests show mgo boards absorb only a tiny amount of moisture—about 0.34%. This keeps your floor safe and clean. Mgo boards scored zero on the ASTM G21 fungal resistance test, which means no mold grows on them.

Particle board has the opposite problem. The wood and glue inside particle board provide food for mold. When particle board gets wet, it absorbs water quickly. This leads to swelling, warping, and loss of strength. You may see particle board crack or break after water exposure. Mold and mildew can spread fast, causing health risks and damage.

  • Mgo boards do not warp, swell, or delaminate after short-term moisture exposure.

  • After many wetting and drying cycles, mgo panels keep their strength. Particle board loses up to 40% of its strength after repeated moisture exposure.

  • Mgo boards last over 30 years in normal weather without degrading. Particle board breaks down much faster in wet conditions.

Note: Mgo boards are ideal for substrate floors in wet and humid places. You will get long-lasting protection against mold and swelling.

If you want a safe, strong, and clean substrate floor, mgo board is the best choice. Particle board may cost less at first, but you will spend more fixing problems caused by moisture and mold.
