Best Practices for 3M 3950
-
Application
Do not apply edge sealer unless the temperature is above the minimum recommended temperature.
Remove any application tape and re-squeegee the edges before applying the edge sealer.
Make sure all edges to be sealed are clean, dry and free of contaminants.
Use the dauber supplied with edge sealer or a ¼ inch (0.6 cm) brush.
Wipe any excess edge sealer off the dauber or brush.
Hold the brush or the flat edge of the dauber so that it straddles the film and substrate.
Pull the dauber or brush along the edge in a smooth, continuous motion. Make sure the entire edge is covered with no gaps.
Use opened and/or mixed sealer within two hours and discard any used sealer.
Air dry for 24 hours before putting the graphic into service.
