PLEXIGLASS, AN ALLIANCE OF SOLIDITY AND TRANSPARENCY
Plexiglass, PMMA or Polymethyl methacrylate, is a solid, aesthetic and perfectly transparent material.
When proccessed … it may scratched or opaque. These scratches and whitish areas are unsightly and are a real drawback.
EXTREM SOLID POLISHING COMPOUNDS
Polishing Plexiglass is a delicate process which may be simplified with the use of MERARD polishing compounds and buffing mops.
Polishing causes a slight melting of the polymer of the surface, allowing the uniformity of the material and thus, to give back all its brightness to the piece.
Depending on the origin of the scratches, your polishing must be adapted:
- If the scratches are deep, start with a preparation step.
- If they are finer, you can directly use a polishing or finishing step.
What are the steps for successful polishing?
- Prepare your disc by carding it to remove all compound residues from a previous polishing.
- Clean your part thoroughly and remove any grease and dust residues.
- Apply the compound to the edge of the disc.
- Work delicately by exerting light pressure on your part.
- Adapt the pressure and speed of your lap by checking your result as you go along.
- Advance step by step.
Warning: If the speed or pressure is too high, there is a risk that the polished area will heat up too much and thus degrade the polished area.
