Painting & Weathering
Painting is where cheap props become convincing. The difference between a foam tombstone that looks like foam and one that looks like stone is entirely in the paint job. These techniques work on foam, wood, paper mache, monster mud, and virtually any other prop material.
Base Coating
Start with a solid base coat in the overall color you want (gray for stone, brown for wood, bone-white for skulls). Use flat or matte exterior latex paint — glossy finishes look plastic. Apply with a brush or roller, covering all surfaces evenly. Let dry completely before the next steps.
Dry Brushing
The most important weathering technique. Dip a brush in paint, then wipe most of it off on paper or cardboard until the brush is almost dry. Lightly drag the barely-loaded brush across the prop surface. The paint catches on raised areas and texture, creating highlights.
For stone: dry brush lighter gray over a dark gray base. For wood: dry brush light tan over a dark brown base. For bone: dry brush white over an off-white or tan base. Multiple light passes look more realistic than one heavy pass.
Washes
A wash is thinned paint (about 10:1 water to paint) brushed over the surface. It flows into cracks, crevices, and low areas, darkening them and creating depth. Use black or very dark brown washes over virtually everything — tombstone lettering, wood grain, bone joints, fabric folds. Apply liberally, then wipe off the high points with a rag, leaving the dark paint only in the recesses.
Aging Effects
- Rust — Stipple orange-brown paint with a sponge, then add darker brown-red in patches. Drip thin orange wash downward from bolts or joints for rust streaks.
- Moss/lichen — Stipple dark green with a sponge on stone surfaces, concentrating on north-facing sides and low areas where moisture collects. Add lighter green highlights.
- Dirt — Dry brush raw umber or dark brown along the bottom edges and in corners where dirt would accumulate naturally.
- Wood rot — Build up dark brown and black in patches, add green-gray for mold.
The Three-Layer Rule
Most realistic paint jobs use at least three layers: dark base, medium dry brush, light highlights. Add washes between layers. More layers equals more depth and realism, but three is the minimum for a convincing result.
