PLEXIGLAS^® SHEET: Scratch Removal

Scratch removal should only be used if the surface imperfections are too deep to be removed by light buffing and the resulting optical distortion can be tolerated. Test to see if sanding is required. Rub fingernail along the scratch. If it is felt, then sanding is required.
Use the finest sandpaper that will remove the imperfections. Coarse paper will only create more scratches. Open coat sandpaper should be used.
Try using 600 grit sandpaper wrapped around a rubber padded sanding block. Sand over the scratch using increasingly larger areas of sanding.
If the scratch is not removed step down to 400 grit.
The sanding should be done in directions 30 degrees apart to produce a diamond pattern.
After sanding and stepping down to 600 grit, polish the acrylic.

The following precautions should be observed:

Do not use disc or belt sanders dry.

Wet sanders are preferred but dry orbital sanders can be used with care.

With mechanical sanders, water or oil coolants are desirable.

Heat generation during the sanding operation may degrade the physical properties of the sheet.
