How to Prepare Ceramic Tile for Grout

Ceramic tile must be prepared before it can ge grouted.

Now that you have laid your ceramic tile, it's time to apply the grout to seal the joints and finish the job. According to Tim Carter at Ask the Builder, the two most common types of ceramic tile grout are wall grout and sanded grout. Wall grout, or Portland cement, is used on joints less than 1/8 inch wide. Sand grout is used for larger ceramic tile joints. Before you apply either type of grout, you must first properly prepare your ceramic tile to receive it.

Things You'll Need

• Broom
• Utility knife
• Sponge

Instructions

1. Cure the adhesive underneath the ceramic tile. Most tile adhesive must cure or "rest" for between 24 and 72 hours before the tile is secure enough to handle grouting. Read the manufacturer's specifications on your tile adhesive's container for curing times.

2. Sweep the floor to remove any debris from the surface of the tile, using a broom.

3. Cut away any tile adhesive that peeks out from underneath the ceramic tile and into the joints. Use a utility knife to score the edge of the adhesive along the edge of the tile. Pry the hardened adhesive off the floor with your fingers or scrape it away with your utility knife.

4. Sweep the floor again to remove any loosened debris.

5. Moisten the tile joints with a moist sponge. The water should not pool. Absorb any excess with a paper towel. Portland cement grout glides onto moistened joints more smoothly.
