Polishing Acrylic Sheet

Keep enough moisture on the paper to avoid overheating the acrylic.

Polishing acrylic sheet.

Then take a utility knife and cut along the outline. This process consists of diamonds rotating at high speed over the surface of the material. The original high luster of acrylic sheet can be restored to the edges and surfaces by polishing with a power driven buffer. Place a sanding block in the corner of a sheet of sandpaper and trace an outline around the block with a pencil.

Work your way across the surface with a more coarse sandpaper then move on to a finer sandpaper. Remove the sandpaper and fold it into a workable size. Not every burner is suitable for flame polishing both the shape of the flame and the fuel have a major impact on the end result. Cut out a piece of 180 grit sandpaper.

Repeat for two to three minutes applying constant pressure. Sand the acrylic just like you would with a piece of wood. The polishing process simply begins by blowing away any dirt dust or loose particles that might be on your acrylic sheet. Polishing acrylic edges is not difficult but as stated above the process can be time consuming and if you use the wrong tools you can severely damage the material.

With constant pressure rub the surface using a circular motion. Start by soaking a piece of the 800 grit sandpaper in water applying enough moisture to the surface so that a slight slurry is created when the paper is rubbed in a circular motion against the acrylic. Before this can be done the edges must be sanded as described above. Flame polishing acrylic with the help of a burner you can easily finish the edges of an acrylic sheet.

Submerge a sheet of 600 grit sandpaper in a bucket of water to begin the process of handling heavy scratches. You re likely to get a sore arm long before you get a finely polished surface. Diamond polishing goes together with a buffing process. Use light pressure and keep the sander moving at all times.

Buffing is done after the polishing process has been completed giving the edges an even higher quality polished finish. You can then apply the cleaning product that you have decided to use to a cellulose sponge a soft cloth that is free of lint or even a microfiber cloth. For deep scratches we recommend starting with a 220 grit or 320 grit paper and moving up to a 600 grit or 800 grit. But hand buffing is an extremely tedious process.

Diamond polishing adds a shiny luster to the edges of acrylic.
