Grouting Instructions
Prepare the floor
Step 1. Grouting can be done immediately after the tiles are installed. Before beginning the grouting process,
remove spacers and thoroughly roll the tile to ensure they are firmly bonded to the subfloor. A premixed sanded
acrylic grout with good flexural strength and adhesion is recommended. Traditional cement grouts are not
recommended for use with Armstrong Crescendo tile.
Apply grout
Step 2. Follow the application instructions as specified on the premixed grout container, working small sections of
the floor at a time. Do not allow the grout to dry hard on the face of the flooring before beginning the cleanup
procedure.
Clean the tile
Step 3. If grout sponges alone are not sufficient to clean the face of the tile, a white 3M pad with light pressure may
be used. A clean damp flat cellulose sponge will aid in removing any grout haze remaining on the tiles. Traffic should
be kept off the installation until the grout has completely dried, usually 24 hours.
Step 4. After the recommended dry time, Armstrong™ Once ‘n Done No-Rinse Floor Cleaner and a white 3M pad
can be used to remove any slight haze of grout residue that may be present. Armstrong™ Once ‘n Done No-Rinse
Floor Cleaner should also be used for continued routine maintenance. Do NOT use Armstrong New Beginning or
other floor strippers for cleaning the grout or maintaining the Rounded Edge Tile installation when it is
grouted, as they are too harsh and will degrade acrylic grouts.
Finish
Step 5. DO NOT wet wash tile for at least five days after installation. This will allow the adhesive under the tile to dry
and prevent excess moisture and cleaning agents from interfering with the adhesive bond. Replace wall base and
moldings.
