Summary for plexiglass mirror scratches Discussion
Plexiglass mirror scratches are the focus keyphrase here: Marcy Finkley of Clarksdale, Mississippi asked whether scratches in a one-way mirror panel could be filled or covered after the material was found to be plexiglass rather than glass. The reply explains that acrylic is much softer than plate glass, so scratches are usually addressed by abrasion and polishing rather than by filling. The suggested steps are to sand the surface down, then use ultra-fine sandpaper, and finally polish with a drill-mounted floppy cloth wheel that can “burn” the surface smooth. The answer also recommends getting more specialized help from a local thermoplastic fabricator who works with acrylics, since they use similar sanding and high-speed cloth finishing methods to produce smooth edges and surfaces.
Q. One way mirror like material removed from door which we thought was glass, but found to be plexiglass. Is there anyway to either fill scratches or cover them in some way?

Hi Marcy !
Plexiglass is, relative to plate glass, a soft material.
To remove or partially remove scratches
1. Sand down
2. Ditto but use ultra fine sandpaper
3. Get a drill
4. Insert some floppy cloth …say 10″dia.
5. Turn on drill so that the cloth is hitting the acrylic surface. This will ‘burn’ the surface and ergo remove them thar scratches.
For more or perhaps better advice, go to a local thermoplastic fabricator who specializes in acrylics …
to get a smooth finish on edges, they sandpaper and then
pass the ‘edges’ over a high speed cloth arrangement.
