Seal-A-Line - #040SL
SEAL-A-LINE is a special coating that seals the edge of masking tape on hand painted lines so that no line marking paint migrates under the edge of the masking tape. This creates lines so sharp that they look as if they were cut into the surface with a knife.
Seal-A-Line is applied as supplied using a paint brush or roller after masking tape is put down. The coat of Seal-A-Line dries quickly (10 minutes in good drying conditions). When dry, apply a coat of Novatex textured line paint. When masking tape is removed, the sharpest white line possible results.
