Installation Instructions
• Remove as much of the grout as possible using care to avoid cutting 
into the edge of the adjacent tile. Repeat this process on all four 
sides of the damaged tile.
• Next, heat the tile a few inches in from the corner. While the tile is warm, 
drive a putty knife or screwdriver into the heated area with a hammer 
(Fig. 26). 
• Then, pry upward to release the tile from the adhesive. Continue 
lifting the tile as you heat it until it is completely removed.
• To install the new tile, re-apply DS100 DuraSet Adhesive over the 
exposed suboor using the at side of a trowel; it is not necessary  
to remove the old adhesive. 
•  Allow the adhesive to dry completely to a tack and then reinstall the new 
tile using spacers to maintain the grout line width. 
• Roll the tile with a 100-pound, three-section roller.
• Re-grout the tile with DuraCeramic Grout following label instructions. 
Allow grout to dry for 24 hours and remove any remaining grout haze.
Ungrouted Tile Floors
• If applicable, use a utility knife and carefully cut through the joint sealer 
using care to avoid cutting into the adjacent tiles.
• Follow the same procedure for Grouted Floors to remove the tile and 
re-adhere the replacement tile.
Congoleum UnderFlor Repair Techniques
Repair techniques are very easy on Congoleum UnderFlor installations. 
Use these procedures for repairs for DuraCeramic Origins, DuraCeramic 
Dimensions or Ovations installed over Congoleum UnderFlor.
Ungrouted Repair
• Carefully score the tile to be removed across the corner edge 
about 1 inch from the corner.
•  Apply heat to the area.
• Using a putty knife and hammer, position the putty knife over the 
scored edge and tap it until the corner is released.
•  Apply heat as you go and carefully begin to pry up the piece from the 
Congoleum UnderFlor using a putty knife. If you keep the tile heated, 
it should release without damaging the UnderFlor.
• When the piece has been removed, check the adhesive tack. If it is 
still tacky to the touch, simply position the new piece in place.
• If the adhesive is not tacky, reapply adhesive with the at side of the 
trowel and let it tack up. Then set the replacement piece into place.
• Roll the replacement piece with a roller.
Grouted Repair
• Use a heat gun to warm the grout.
• Using a sharp utility knife, carefully score the joint, cutting through the 
grout. Make sure that you do not apply a lot of pressure because you 
do not want to cut into the Congoleum UnderFlor. Carefully score the 
tile to be removed across the corner edge about 1 inch from the corner.

•  Apply heat as you go and carefully begin to pry up the piece from the 
Congoleum UnderFlor using a putty knife. If you keep the tile heated, 
it should release without damaging the UnderFlor.
• When the piece has been removed, check the adhesive tack. If it is 
still tacky to the touch, simply position the new piece in place.
• If the adhesive is not tacky, reapply adhesive with the at side of the trowel 
and let it tack up. Then set the replacement piece into place.
• Roll the replacement piece with a roller.
• Re-grout the tile with DuraCeramic grout following label instructions. Allow 
grout to dry for 24 hours and remove any remaining grout haze.
 Replacing the Congoleum UnderFlor
If the Congoleum UnderFlor is cut or damaged during the repair 
procedure and needs to be replaced, follow these procedures.
• Using the piece that was removed as a template, cut a ll piece of Congo-
leum UnderFlor.
• Slide pieces of thin, clear, sticky, one-sided packaging tape centered under 
the cut out edges. 
 Tip: Here’s a tip to make it easier to slide the tape under the edges. Cut the 
piece of tile that was removed to make it about 1 inch shorter. Cut the thin 
packaging tape to that dimension. Carefully fasten the tape along the edge of 
the product overlapping it about 1/4 inch. Turn the piece over so that the tape 
is now sticky side up and slide it under the cut out edge. Firmly press down 
on the edge and pull the replacement piece away to release the tape.
• Carefully lay in the new cut piece of UnderFlor pressing it rmly  
onto the tape.
•  Apply DS100 adhesive to the Congoleum UnderFlor and allow 
it to tack up.
• Lay in the replacement ooring and roll it to set it in place. 
• Roll the replacement piece with a roller to set it.
• Re-grout the tile to nish the repair.
QuikStik UnderFlor Repair
Repairs are very simple. To replace a damaged tile:
• Warm the piece with a heat gun.
• Use a sharp utility knife to cut through a corner of the damaged piece      
taking care not to cut into the QuikStik Underor.
• Lift the end of the piece and continue heating.
• As you provide sufcient heat, the piece will release from the adhesive.
• Lift out the entire piece and warm the exposed adhesive.
• Install the new piece and set it rmly into place with a hand roller.
PREVENTIVE CARE
• Make sure furniture legs have large surface, nonstaining oor protectors. 
Replace small, narrow metal or dome-shaped glides with smooth, at 
glides that are in at contact with the oor. Glides should be equipped with 
self-adhesive felt pads to avoid scratching the surface of the oor. 
The 
pads should be checked periodically for grit and wear and replaced when 
necessary. 
• Heavy furniture or appliances that are not moved often should be equipped 
with at, nonstaining composition furniture casters or cups of appropriate 
size – available square from 1 1/2" to 2 5/8" and round from 1 3/8" to 1 
5/8".
• Mobile appliances and furniture should be equipped with easily swiveling 
casters. They should be at least 2" in diameter with nonstaining 
hard rubber treads at least 3/4" wide. Do not use ball-shaped casters.
• Place mats at outside entrances to prevent dirt, grit and soil from 
being tracked onto your oor.
