How to Remove Mastic from Ceramic Tile

Sometimes during the installation process, excess mastic may get left on the surface of the tile. This is nothing to worry about, as removing mastic is a simple procedure that can be done within a few minutes using nothing more than warm water and a sponge.

Difficulty: Easy

Instructions

Things You'll Need:

• Water Sponge

1. Use warm water and a sponge and dampen the mastic.

2. Let sit for a few minutes. Using the sponge, gently scrub the mastic until it comes off.

3. Let the area dry for a few minutes. Check to ensure all the mastic is removed. If it is not, simply repeat the process until all the mastic has been removed.

Tips & Warnings

• Water softens mastic so it is incredibly easy to remove. If mastic is stubborn, you can use a scrubbing brush instead of a sponge for the initial removal. Use the sponge for cleaning up after the scrubbing.
