HOW TO POLISH YOUR PLEXIGLASS PIECES?

The polishing of Plexiglass is a technical polishing which is simplified by the use of MERARD buffing mops and compounds.

Polishing leads to a light melting of the polymer on the surface, allowing the uniformity of the material and thus, to give back all its shine 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 go directly to a polishing or finishing phase.

What are the steps to follow for a successful polishing?

Prepare your disc by carding it in order to remove all the compound residues from a previous polishing
Clean your workpiece thoroughly, removing any grease and dust residue
Apply the compound to the edge of the disc
Gently work with a light pressure on your piece
Adapt the pressure and the speed of your lathe by checking your result as you go along
Advance progressively

Caution: A speed or a pressure too high could lead to a too important heating of the polished zone and thus to a degradation of the latter.
