Your theatre’s local Fire Department has codes governing the flammability of materials used on stage. It is important that you know these fire codes. Since most flameproofing compounds protect for approximately one year, complying with the code can be quite a task.
The fabrics used to construct stage curtains are usually flameproofed and these fabrics are easy to treat while they hang by spraying the back of the fabric with the proper solution.
Flameproofing scenery and the stage can be challenging. Basically the wood frames and stage should be coated with WD flameproofing solution. Scenic fabrics, if not already treated, can be flameproofed during the sizing process. Painting the scenery with a casein paint is the best option because it will not support a flame. If you want to paint with latex acrylic paints, we stock a flameproofing paint additive.
Flameproofing can be applied many ways, such as with a roller, brush, sprayer or by immersion. If you are using a brush or roller, allow the solution to soak through and dry before applying paint. Spraying is the fastest way. Try the #HS223 P-50 Hand Sprayer, which is an excellent paint sprayer as well. Drops can be dipped into the solution, gently wrung out and hung up to dry. Be sure to use a large enough container for soaking to insure that all the fabric is treated.
Warning: If you get flameproofing products in your eyes, wash immediately with water. Follow with a soothing eye solution from a drug store.
• When the following products are applied, they render materials flame-retardant according to NFPA701
