Scratch removal from acrylic

Acrylic is a plastic with many appealing properties. Unfortunately, it also has a disadvantage compared to glass: in that it is prone to scratches. Removing scratches from acrylic is relatively easy, and with the right maintenance, acrylic will also stay beautiful for a long time. In this blog, we explain in detail how to remove scratches from acrylic and how best to maintain this plastic.

Different types of acrylic – different polishing methods

Acrylic comes in two types: moulded and extruded acrylic. The latter variant is also called cheap acrylic or acrylic XT and is harder to work with than moulded acrylic. This also means that it is harder to polish, at least if you want to polish by machine. We recommend you polish extruded acrylic manually. To do this, use a microfibre cloth and a special polish from Zvizzer or Xerapol/Quixx. These polishes can also be used on a machine polisher. For mechanical polishing, we recommend a backing pad with polishing wool or lambswool for the drill.

steps

  1. Clean the surface

    Before repairing scratches, the surface must be thoroughly clean. Make lukewarm soapy water with household soap (green soap) and use a microfibre cloth to clean the entire surface of the acrylic sheet. Any dirt and dust residue may cause new scratches during polishing. Save the suds for later!

  2. Assess the depth of the scratch

    Very carefully run a fingernail across the scratch(es) you want to repair. If your nail sticks, even slightly, it is necessary to sand away the scratch(es). If your nail does not snag, you can immediately start with step 5.

  3. Sand away the scratches

    To sand away the scratch(es), use waterproof sandpaper. This is sandpaper with a fine grit, the sandpaper or surface should be wet while sanding. Start with 1000 grit and sand away the scratch(es) from the acrylic. Repeat the test with your fingernail to feel if the scratch has actually disappeared. When the scratch has disappeared, sand a slightly larger area with an even finer grit, preferably grit 2500. Keep the surface moist while sanding!

  4. Clean the surface thoroughly

    Rinse away all the sanding residue with the soapy water you made earlier. Instead of wiping the surface dry with a cloth, dab it with a clean, dry cloth.

  5. Polish the scratch and surface

    Spread a small amount of Xerapol/Quixx or Zvizzer heavy cut polish on the surface of the acrylic and start polishing, either by hand or with the rag wheel. Continuously assess the result and do not keep polishing at one spot for too long with the polishing cloth/polisher. Wipe the polished area occasionally with the damp cloth to assess the shine. When the scratch is no longer visible, you can start repolishing.

  6. Repolishing

    Repolishing means giving the entire surface a uniform sheen again. You do this with Zvizzer Fine cut polish. Clean the surface well again with the damp cloth and pat it dry with the dry cloth. Spread the polish over the surface (a small penny-sized dot everywhere) and start polishing again. If you do this by hand, use a different cloth than the one you used for polishing. If you do this by machine, use the polishing wheel! Be careful when re-polishing by machine, keep the machine constantly moving – acrylic is very sensitive to heat!

  7. Conservation

    Once the surface of the acrylic is shiny again, you will want to keep it looking nice for as long as possible. We recommend using Vuplex for this purpose. After a treatment with this cleaning and preserving agent, the surface will remain beautiful for longer and also remain anti-static. Because what is beautiful should stay beautiful.
