If you want to give the viewer of your model railway system an insight into your factory, there should be something to look at. In addition to machines and systems, interior walls are an absolute highlight.

Let us assume that this factory was built at the beginning of the 20th century. It only can be realistic, if the walls are not complete but only partly plastered and crumble. The easiest way to deal with this situation is to blind outer walls with "inner walls". In this case, it is red brickwork. The plaster imitates, with a fine spatula from the tube. You can acquire one at the building market.

2.

Age the wall parts first, as described in the previous tinker. After the paint is dry, stick the surface, which is not to be plastered. In the case of several wall sections, this should be approximately uniform.

3.

The water-dilutable spreadable fine filler is applied with a flat, soft brush. Places where the plaster crumbles are spared.

4.

After the filling compound is dry, the wall can also be aged above the floor. Black watery paint is applied in different places; sometimes more and sometimes less.

5.

Here you have the direct comparison between the original and the partly plastered and "brittle" variant.

6.

The width must be adjusted before installing the inner walls. When gluing the two walls together, ensure absolute coverage. Please use a small amount of glue on the outer edges of the windows.

7.

The construction joints between the individual wall sections are covered with "concrete pillarsl". The cable ducts, item 41 620, are suitable for this purpose.

One of the switchboxes from item  41 620 takes its place.

Finished! And the look is very realistic but no comparison to the bright and clean workrooms today.
