A damaged object or a decorative pattern to reproduce, the best mold removal company will give you the right solution. Adopt the mold technique, latex or silicone paste. It’s easy and fun!

Latex

  • Flexible, latex (rubber) is a quick and easy way to faithfully reproduce the most complex patterns. The imprint obtained may receive molding plaster or a polyester resin. The demolding is carried out without problem in both cases.
  • Demonstration via the repair of a much damaged old frame.
  • Dust with a moist cotton swab the least damaged part of the frame.
  • Clog up any cracking with putty.
  • Sand after curing
  • Recoat (if necessary) unstable elements with vinyl wood glue.
  • Cut out strips of modeling clay with the cutter.
  • Flatten them with a rolling pin and use them to make a well-sealed formwork (provide reinforcements to prevent sagging under the pressure of the liquid rubber).
  • Mix the rubber and catalyst in a bowl according to the manufacturer’s instructions.
  • Pour the liquid into the formwork (avoid air bubbles).
  • As the soft rubber is self-releasing, you do not need a release agent.
  • Remove the modeling clay from the formwork after 24 hours.
  • Remove the rubber footprint.
  • Load this model of modeling plaster.
  • Apply a layer of “creamy” plaster on the damaged part to glue the new decor.
  • Resume the decor with a painter’s knife and sandpaper to soften the contours.
  • Fill the gaps with a filling compound and sand.
  • After drying (about a week), switch to coloring.

Silicone paste

The silicone paste is in the form of two components to be mixed at the time of use. It allows making flexible molds. With a high fidelity in its capacity to marry the finest contours, this paste does not flow and allows working in any position.

  • Mix the two components of the silicone paste equally (one is white and the other is blue).
  • Take the necessary amount and intimately mix the two products until you get a single color.
  • Apply the paste to the finger, without delay, on the part or parts of the pattern whose imprint will be used.
  • After 15 minutes, remove the mold.
  • Mark in pencil (or felt) the direction in which the mold must appear on the object.
  • Fill the mold with polyester putty (adding a small amount of hardener) without putting too much (at the risk of sanding) or not enough (missing fill).
  • Apply a thin layer of putty, with a knife, on the break (to promote adhesion) and put the silicone mold with its contents.
  • Use the markers previously drawn to position the mold.
  • Let the putty harden.
  • Unmold after 1/4 hour and sand.
  • Use an abrasive grain of 120, then 160 and 200. Finish with an extra fine grain of 400.
  • Paint the repaired part with oil paint and blur with pencil.
