Rosco · flame retardant paint additive

Flame retardancy you mix straight into the paint

Flamex PA is a clear, un-pigmented flame retardant additive mixed into water-based paint to make the finished paint film flame retardant. It lets scenic artists keep their chosen paint system while adding flame retardancy to the painted surface — one jar per gallon (3.79 L) of paint.

Choosing

Best for — and the alternatives

Flamex PA is best for

  • Adding flame retardancy to a paint film
  • Keeping your existing paint system and colour
  • Scenic murals and painted sets
  • A simple one jar per gallon ratio

Treating the material instead?

Flamex PA treats the paint layer, not the substrate. If the raw material needs treating:

  • Flamex MC → wood, foam & mixed materials
  • Flamex NF / DF → natural / delicate fabrics
  • Flamex PC → paper & cardboard
The hard numbers

Flamex PA specifications

Flamex PA slows the spread of fire across the paint coating — it does not change the flammability of the material beneath it. Treat the substrate separately where required.

Flame retardants reduce flammability; they do not stop materials from burning. Always test on a sample and follow the venue's fire authority requirements and the product data sheet.
