Amonn Amotherm Wood 451 SB Fire Retardant Basecoat - White 2K Kit
The same certified fire protection as the clear Amotherm system, for timber that is going to be painted a colour rather than left as wood. Amonn Amotherm Wood 451 SB Basecoat is the pigmented, white version of the fire-retardant basecoat — a two-component, solvent-based polyurethane carrying the reactives that decompose under flame, release inert gases and slow the charring of the timber.
Sold as a complete 2K kit — 5 kg Component A (white) + 5 kg Component B hardener, mixed 1:1. It is the first half of a system; the second half is the tinted Amotherm Wood 451 SB Topcoat.
The classification only holds as a system
Classification report CR-09.2025-1 (BM Certification, EN 13501-1:2018) certifies B-s1,d0 for the Amotherm Wood basecoat together with its topcoat, and states the classification is valid for any colour. It holds at:
- 200 g/m² of basecoat — or 300 g/m² if you sand between basecoat and topcoat.
- 160 g/m² of topcoat over it. Both coats, always.
- On wood-based substrates of at least 680 kg/m³ density and 12 mm thickness, fixed with no air gap behind, on walls and ceilings.
How much you need
One kit gives roughly 10 kg of mixed basecoat — about 50 m² at 200 g/m², about 33 m² at the sanded rate. Pair each basecoat kit with one topcoat kit.
Working with it
- Substrate: raw wood, or wood with a non-film-forming primer. Not over wax or water-repellents. Moisture below 15%.
- Mix: the fire-retardant solids settle — stir Component A right through with a paddle mixer before adding B. Pot life 90 minutes.
- Apply by airless (60–120 bar, 0.011–0.015 inch tip), conventional spray or curtain coater. Brush possible, finish poorer.
- Coats: one or two to reach 200 g/m², the second between 1 and 4 hours after the first. Topcoat within 8 hours without sanding, or after 12 hours with sanding.
- Conditions: at least 10°C and below 60% humidity. Dust-dry in 30 minutes, through-dry in 12 hours.
What it is not
Interior only as supplied. No UV or biological protection — an impregnating primer goes on first where either is needed. Oily species need a polyurethane insulating primer under it. And it is white only: the colour comes from the tinted topcoat, not the basecoat.
