How it works:
Safewalls Insulating basecoat expands in a fire to create a resilient insulating barrier.
Safewalls Anti-Viral Smoke and Flame Retardant emits a safe fire
damping vapour in a fire to control flame spread and suppress smoke.

safewalls SFR’s polyurethane hardened acrylic “cross-links” during the drying process to form
a smoother, harder, more cleanable surface than typical wall paints and help eliminate the
microscopic pockets that host bacteria which prevent effective cleaning.
A unique concentrated mix of safe, biocidal metal encapsulated nano-particles attacks
viruses and bacteria that settle on surfaces, damaging their protective “envelope” to kill their
live cores and disable their spikes penetration of lung’s cells

Fire Test:
FIRE TEST STANDARDS in UKAS and EOTA – accredited Fire Test laboratory
BS EN Class B s1 d0 (old Class 0 compliant) over 10, 14 and 20 coats of all wall paint types used
on buildings since Vinyl, acrylic, oil based, anti-graffiti, with or without wallpaper and the
flame retardant paint that emits toxic antimony gas.

Microbial Test:
Surfaces coated with Safewood are designated Anti-Viral in just 2 hrs
91.5% “1 Log” Coronavirus reduction in 2hrs to approved test ISO 21702
99.9% “1 Log” bacteria reduction in 24hours to approved test ISO 22196
In approved UK Microbiology Laboratories.
