How long does the fire retardant treatment last?
Certification remains valid for up to five years or five dry-cleaning cycles, whichever comes first. Curtains must be retreated if they are laundered.
How long will the work take?

A professional water-based fire retardant is suitable for most fabrics. Sample testing is recommended for delicate or unusual materials.
