Underlayments are the support materials that lay underneath your tile on a floor. They sit between your subfloor (usually plywood) and your tile. They provide a water-stable base, make the floor more rigid (less chance of cracked tiles), and are bettersuited for tile adhesion.

What is the best underlayment for tile? Exterior plywood is an acceptable underlayment for tile and is preferred to interior-grade plywoods because the bonding adhesives used are waterproof. If water seeps through the tile installation to the underlayment, it will not cause the wood to swell, as happens with interior-grade-plywood.
