How do you install porcelain tile?

Answer 1

Basically, there are a few acceptable substrates for porcelain floor tile. Cementitious backerboard is usually preferred. Avoid using interior-grade plywood, OSB, multi-layer sheet flooring.

A growing trend with porcelain tile is larger tiles and smaller grout joints, both of which require a very flat floor. For this reason, you may have to use a self-leveling compound. Most self-leveling compounds make an outstanding substrate, but it's wise to use a product from the same manufacturer as the rest of your setting materials to avoid compatibility issues.

Use a premium thinset with strong bonding agents that are modified with latex - either premixed or as an additive during mixing.

Allow enough time for the thinset to dry (typically 24 hours) before grouting.

Forget traditional carbide cutting tools when cutting porcelain - you'll want drill bits, hole saws and saw blades with diamond edges.

Answer 2

To install porcelain tile, first prepare the surface by ensuring it is clean, dry, and level. Next, apply thin-set mortar with a notched trowel, then place the tiles firmly in the mortar, spacing them evenly with tile spacers. Once all tiles are in place, allow the mortar to dry completely before grouting. Finally, apply grout between the tiles, wipe off excess with a damp sponge, and seal the grout to finish the installation.
