Amonn Amotherm Wood 451 SB Fire Retardant Topcoat - Tinted Matt 2K Kit
The coloured topcoat for the Amotherm fire protection system, and the second half of it — not optional. Amonn Amotherm Wood 451 SB Topcoat is a two-component, solvent-based polyurethane in a matt finish (12–18 gloss), tinted to your RAL or NCS reference by Amonn before dispatch. It seals and protects the white 451 SB basecoat; the classification is for the pair.
Sold as a complete 2K kit: 5 kg Component A + 5 kg Component B hardener, mixed 1:1. Two tinting bases:
- Base W — white and light to mid colours.
- Base D — deep and strong colours. A specialist base, priced accordingly.

The rate that matters
Classification report CR-09.2025-1 certifies B-s1,d0 to EN 13501-1 at 160 g/m² of topcoat over 200 g/m² of Amotherm Wood 451 SB Basecoat (300 g/m² if sanded between coats), on wood of at least 680 kg/m³ and 12 mm, fixed without an air gap. The report states the classification is valid for any colour.
How much you need
One kit gives roughly 10 kg of mixed topcoat — about 62 m² at 160 g/m². One topcoat kit to one basecoat kit is the normal pairing for up to 50 m².
Working with it
- Timing: onto the basecoat within 8 hours of its last coat without sanding, or after 12 hours with a 220–240 grit sand.
- Mix 1:1 with the hardener supplied. Pot life at least 3 hours.
- Apply by airless (60–120 bar, 0.011–0.015 inch), conventional spray or curtain coater. Brush possible, finish poorer.
- Drying: dust-dry 25 minutes, dry to handle and through-dry 24 hours. Work at 10°C or above, humidity below 60%.
- Keep to the stated rate — over-application clouds the film.
What it is not
It is not fire-retardant on its own — that is the basecoat’s job. Interior only as supplied. No UV or biological protection. It is a tinted product made to order, so it cannot be returned once mixed.
