Timber & plywood treatment

FiremanBrand™ Flame Guard

A halogen-free, water-based flame retardant developed specifically for raw timber and plywood. Wood remains combustible — this treatment measurably delays ignition and reduces flame spread.

Test results — three specimens

Untreated plywood compared against 2-coat and 3-coat brush-applied treatment, tested under SANS 10177 – Part 9.

Measure	Untreated	2 coats	3 coats
Time to ignition	0:10	3:25	6:02
Length of flame spread	53 mm	4 mm	3 mm
Length of heat damage	256 mm	220 mm	226 mm
Glowing after burner removal	8+ min	~1 min	None

More coats produced measurably better performance across every test measure. Full report available on request.

What "flame retardant" means for wood — honestly Wood is a combustible material, and no surface treatment changes that. What this treatment does is measurably delay ignition and reduce how far flame spreads once ignition occurs — the data above shows that difference directly. We won't claim "non-combustible" or "fireproof," because neither is accurate.

Applications

Raw timber and plywood in construction
Mining support structures
General timber fire-risk reduction

Application method

Applied by paint brush or roller — 2 or 3 coats, with drying time between coats. More coats deliver measurably better performance; see the test data above.
