How to repair a DuraCeramic

Updated February 21, 2017

DuraCeramic is a proprietary tile manufactured by Congoleum. The tile consists of a limestone composite base strengthened with a polymer resin. It is installed in 40 by 40 cm (16 by 16 inch) or 20 by 20 cm (8 by 8 inch) squares or in a combination of the two sizes. The tiles may be grouted or installed edge-to-edge and sealed with a joint sealer. DuraCeramic tile is called resilient, durable, and easy to maintain. When it does get damaged, it is also easy to repair using a few simple tools.

Repairs on grouted tile

Warm the grout along one edge of the tile by using a heat gun.

Cut the heated grout with a sharp utility knife, using a straightedge as a guide.

Remove the grout, being careful not to cut into the edge of the undamaged tile.

Repeat until you have removed the grout from all four sides of the tile.

Heat a corner of the tile, using the heat gun.

Drive a screwdriver into the heated area of the tile, then pry the tile upward.

Continue heating and prying until you can remove the entire tile.

Apply DS100 DuraSet Adhesive to the subfloor under the removed tile.

Allow the adhesive to dry until it is tacky, about 45 to 60 minutes.

Use spacers to install the new tile and maintain the distance needed for grout.

Roll the tile with a 45 kg (100 lb) roller.

Grout around the newly-installed tile using DuraCeramic Grout and allow it to dry for 48 hours. Wipe clean.

Repairs on ungrouted tile

Cut through the joint sealer using a sharp utility knife, being careful not to cut into the undamaged tiles.

Follow steps 5 to 9 in the section above to remove the damaged tile and replace it.

Apply DuraCeramic DS200 Joint Sealer on all four sides of the replacement tile.

Roll the tile with a 45 kg (100-pound lb) roller and allow it to dry for 48 hours.
