Acrylic sheet is manufactured with masking on both surfaces to protect the sheet from scratching during storage and handling.
The masking is a polyethylene film. Marking on polyethylene masking may be done with a grease pencil and certain felt-tipped markers.
Removing Masking
Sheets should be stored in the original shipping carton before use. Masked sheets should never be left in direct sunlight or outdoors for 8 hours. During most fabrication operations, the sheet masking should be left in place to protect the sheet surface from dirt and scratching. The masking may be removed for intricate detail work on the sheet if necessary. Avoid handling unmasked sheets unnecessarily. Certain heat sources used in line bending and thermoforming operations may also require the removal of the masking.
You can remove the paper masking with a cardboard tube by rolling the masking around it. Masked acrylic should be kept from heat and sunlight, and masking should be removed soon after installation. If the adhesive has hardened, moisten it with aliphatic naphtha, hexane, or kerosene will help to soften it. Do not use gasoline or sharp-edged objects like razor blades. Any oily film left behind by solvents should be removed immediately by washing.
