Tutorial

Our models have to be painted. The painting of our models is done without difficulty even by a novice modeler. It takes as much time as mounting a plastic injected kit for a more satisfactory result.

The house of the Cevennes Village in N

The PLM train station in N

 

The PLM train station :

Used material :
  • Matte light gray acrylic paint
  • Matte black acrylic paint
  • Matte ocher acrylic paint
  • Matte orange acrylic paint
  • Matte red acrylic paint
  • Matte beige acrylic paint
  • Matte light gray-blue acrylic paint
  • Matte ocher Humbrol Enamel paint
  • Fine paintbrush (5 mm wide)
  • Thin paintbrush (2 mm wide)
  • Paint palette
  • Sponge kitchen and water pan
  • Craft knife and scissors
  • Abrasive paper
  • Gel cyanoacrylate glue
  • Gel glue
  • Printer and matte photo paper
  • Transparent plastic sheet
  • Cardboard 0,5 mm
  • Bowl, colander and hot soapy water

This model is made in Acrylic polymer, a hard material that offer very fine detail.

Only the roof is made in Fritted polyamide, a cheaper, stronger and flexible material but less precise.


The model is composed of several parts. First check that all are present. Then check that they assemble together properly.

It is advisable to wash in warm soapy water (not over 40 ° C) parts in Acrylic polymer to remove traces of wax they might still contain.

Tip: To avoid losing small parts, use a colander.


The facades in Acrylic polymer are thin. To strengthen, cardboard reinforcements are planned.

Download cutting patterns (on the catalog page) and then print them on a sheet of paper.

This sheet is then glued to the board with the gel glue. Cardboard should have a thickness of at least 0.5 mm.


Then cut up the different pieces of reinforcements.

They are then glued to the rear facades with the cyanoacrylate glue.


The paper of the cutting patterns must be inward. The cardboard surface of the reinforcements must be glued on the facades.

We can see clearly here the translucent aspect of the Acrylic polymer.


A primer is then applied to all parts.

The Acrylic polymer (light brown) must be painted with Humbrol Enamel paint types. An acrylic paint applied directly adhere very badly.

The roof in Fritted polyamide is directly painted with a light gray acrylic paint.

Tip: to paint small parts, use double-sided tape to hold them.


The background of the facades is then painted in beige (acrylic paint). Several layers are passed to give some relief to these surfaces.

Red (acrylic paint) is then applied to the bricks.

After drying, the light gray paint (acrylic paint) is applied to cover the stones and roof elements.

After drying, the brick's joints are filled with the same light gray but very diluted with water. This mixture applied sparingly comes naturally fill the joints.

The roof is painted in orange (acrylic paint) and before drying, a red layer (acrylic paint) is applied unevenly to create this heterogeneous appearance.


The underside of the roof gets a light gray paint.

The bottom of the facades (natural stone) receives a new ocher layer (acrylic paint) irregularly applied for leave the underlayer appearing in some places.

The channels and the roof edge will receive a light gray paint (acrylic paint), like shown in the next photo.


A very dilute black (acrylic paint) is applied on the roof, on the bottom and on the background of the facades and on the doorframes. It helps reveal the joints and add patina to the surfaces.

The application of black paint must be very carefully and excesses must be immediately cleaned with a damp sponge (see the tutorial in the previous model).

You must treat the parts before assembly contrary to what may suggest this picture.


The assembly of the different parts is made with cyanoacrylate gel glue. The windows are glued with 4 points of glue applied on the corners. It is recommended to scrape the paint where glue will be applied for optimal adherence.

Transparent plastic comes form the windows, it is pasted with the adhesive gel (the cyanoacrylate glue is banned, it deteriorates this type of plastic).

Curtains are pasted behind. They come from our printing plates available on the page of our catalog.


The station is then assembled starting with the walls.

The cyanoacrylate gel glue is used here, other glues having trouble taking on the Acrylic polymer. You must firmly press the two parts to be assembled for 20 or 30 seconds for the glue holds well.

The roof is added after. It may be necessary to grind it with sandpaper. He holds herein by interlocking.


The flaps are glued at last to avoid it to be unstuck during assembly. This is the gel glue that is used here.

The model is finished.
