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 vapor 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, eliminating microscopic pockets that host bacteria.
A unique concentrated mix of safe, biocidal metal encapsulated nanoparticles attacks viruses and bacteria on surfaces, damaging their protective envelopes and killing their live cores, disabling their spikes’ penetration of lung cells.
Fire Test:

Tested to BS EN Class B s1 d0 standards over 10, 14, and 20 coats of all wall paint types used in buildings.
Microbial Test:

Surfaces coated with Safewalls are designated Anti-Viral in just 2 hours, with a 91.5% reduction in Coronavirus in 2 hours and a 99.9% reduction in bacteria in 24 hours, as tested in approved UK Microbiology Laboratories.
Pack Sizes:

Available in 25 sqm and 50 sqm pack sizes to aid correct application.

Apply one good coat over Safewalls Insulating Basecoat using brush, roller, or spray methods.
VOC Content Composition:

Low VOC content meeting EU limits.

Safewalls Insulating Basecoat must be clean and fully hard dry before use.
