Ask the Expert: "How do I apply floor graphics over grout lines?"
Before applying a floor graphic, wash the floor substrate and then wipe the surface with isopropyl
alcohol from the center of the area that the graphic is being positioned to the outside edge of the
graphic area. Let the alcohol evaporate.
Position the floor graphic in the cleaned area. Remove the liner and, using a 3M™ Hand Applicator PA-1
Squeegee (blue or gold), apply the graphic to the substrate using firm overlapping strokes and working
from center to edge. Bridge the film over grout lines without working the film into the grout lines.
When applying a floor graphic to an area that is tiled and has grout lines, the floor graphic must
be bridged over the grout lines, and not down into them. There are two main reasons for bridging:
Most grout lines are sealed with a silicon sealer that will not let the adhesive adhere to the grout lines.
The floor graphic film is not conformable. The film will pop back to a flat position if forced into the grout lines.
Following these instructions should result in a smooth floor graphic and a satisfied customer.
