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!
- 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.
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.
