Flame retardant muslin fabric is a popular cotton sheeting fabric. Many venues require scenic theater fabrics to be flame retardant. CCS’s flame retardant muslin fabric can be left unpainted or lightly painted. The muslin has shrunk a little when treated with the Flame Retardant solution, making sizing less of an issue. Heavier paint applications require more care to prevent re-crystallizing of the FR treatment. Our flame retardant muslin fabric is often used for cycloramas, stage drops, and scene flats, depending on the weights of the muslin. Muslin weight is typically categorized into 3 groups: light weight, medium weight, and heavy weight. We carry a large variety of colors with our flame retardant muslin fabrics.
