How to Set Ceramic Wall Tile in Mastic

Ready-to-use organic tile adhesive sets ordinary ceramic wall tile on a sound, dry interior wall. Read the adhesive's data sheet first, because it sets the notch size, wall limits and wait times.

Steps

Read the adhesive, tile and wall instructions together. Check the adhesive allows your tile, wall and exposure.
Make the wall sound, flat, dry and clean. Repair loose board, cracks and bumps.
Dry-lay the field with your joint width and set the layout lines. Mark cuts for outlets, valves and corners.
Turn off the circuits that reach the wall.
Key a thin coat in with the flat of the trowel, then comb it in one direction with the notch the data sheet names.
Set a test group of tiles, then lift one. If corners or ridges are bare, stop and fix the notch, angle or open time.
Spread only what you can tile before the adhesive skins. Set courses from your layout line with spacers.
Clean tile faces and joints while the adhesive is fresh. Wait the full set time before you grout.

Tips

If the adhesive names a 3/16" x 5/32" V notch, the 19110 is the durable hand trowel and the 05532 is the one-piece plastic option.
A larger printed notch is not permission to use it with a bigger tile. The data sheet must allow it.
Keep notch edges free of dried adhesive. A coated or damaged edge changes the bed.
Heat, airflow and porous walls shorten the time you have, so spread smaller sections.

Watch out

Adhesive is not waterproofing and does not fill movement joints. Check the data sheet for wet areas such as shower walls.
Tile on a wall does not make it fire-rated. Check fire-rated assemblies and heat sources behind a range or fireplace.
Stop and take down fresh work if lifted tiles show poor coverage, or if tiles slide or sag.
