Detailing and weather can really add authenticity to a scene.

I always use flat (not glossy) acrylic paints for painting structures. The trick is to paint the parts (either with an airbrush or using a paint brush) BEFORE installing them. This is really important, because most adhesives will prevent the paint from sticking, or the washes from soaking in.

It is easier to paint a structure before assembling or installing it in place. You shouldn’t have to lean over your layout to paint a structure as this is uncomfortable and will result in a messy job. It is easier and neater to assemble pieces after they are painted.

Usually start by painting the lightest colors first, before painting the darker colors.  It is generally easier to touch up lighter colors with darker tones, rather than the other way around. However, in saying that, there are exceptions to the rule. Thin washes of light paint colors can sometimes add an excellent weathered look when applied over dark colors. I have seen this done on the sides of rolling stock wagons and on brick walls where thinned washes of light browns and light reds are applied over black paint.

The online Model Train Club has a section on Detailing & Weathering as well as a section on Building Structures, and another on Making Scenery. Watch the 3 new videos.

A little trick I use is to apply some paint on an old rag and then drag the strip-wood through your fingers while holding the rag. This can give the effect of well aged paint.
