Sansin Firestop 99

Sansin Firestop 99 – Class A Flame Spread Protection with a Clear Wood Finish | Available at Hue & Hammer Vancouver

Sansin Firestop 99 is a high-performance, intumescent fire-retardant coating that delivers Class A flame spread protection in a beautiful, translucent wood-toned finish. Designed for interior wood surfaces, Firestop 99 expands when exposed to heat, forming a thick, charred insulating layer that blocks oxygen and slows the release of combustible gases—dramatically reducing flame spread and smoke generation.

This low-VOC, water-based formula is ideal for use on plywood, OSB, laminated timbers, and other porous combustible materials. It offers excellent adhesion, fast drying, and easy soap-and-water cleanup. Available in clear or custom-tinted tones, Firestop 99 is perfect for residential, commercial, and institutional projects requiring both fire safety and aesthetic appeal.
