What it is for
Foamcoat is excellent as a protective coating for all types of foam projects. It is especially useful on foam scenery or props that receive physical abuse or need to last for extended tours. It can also be used as a texturing agent that is much more durable than plaster or joint compound.
Foamcoat can be used on a wide variety of surfaces, including foam, primed wood, concrete block, primed fibreglass, papier mâché, muslin and many other materials. It provides a hard, durable finish that resists chipping and cracking, yet can be sanded smooth or carved to add detailing.
Preparing the surface
All surfaces should be clean and dry before you apply Foamcoat. Prime wood and plastic first. For particularly difficult materials, lightly sand the surface to give it more "tooth" before applying Foamcoat.
Applying it
Apply Foamcoat by brush, roller or hopper spray gun, depending on the finish you want. The thickness of the coating is determined by the application.
- When coating over fine details, use successive thin coats to build up a protective layer without obscuring the details.
- For an extra smooth finish without sanding, smooth the coated surface with a wet sponge just before the Foamcoat has set completely.
- Use Foamcoat undiluted for the most durable single-coat application. It can be diluted if you wish.
Drying
Foamcoat dries in 2 to 8 hours, depending on the thickness of the coating. Allow 24 hours for a full cure.
Painting and tinting
- Foamcoat is compatible with all water-based coatings and is easily painted or tinted.
- You do not need to prime Foamcoat before painting.
- Tint Foamcoat with Supersaturated Roscopaint or Universal Tints.
