Intumescent Paint For Wood

About Intumescent Paint for Wood Derivatives & Timber

Intumescent paints for timber are available with fire ratings of up to 60 minutes, British Class 0/1 and Euroclass B. These paints are able to give a highly decorative finish for use internally and externally. On external wooden cladding where a Euroclass B rating is applicable, we recommend that an impregnation flame retardant is used in place of an intumescent paint or varnish, for longevity purposes.

Intumescent and flame retardant products come in 3 forms:

– Pigmented paints – Up to 60 minutes rating, Class 0 and Euroclass B

– Clear Varnishes – Up to 60 minutes rating, Class 0 and Euroclass B

– Clear impregnation treatments – Class 0 and Euroclass B

How Does An Intumescent Paint Protect Wood And Why Is It Needed?

Intumescent Wood paints are what we refer to as “Reactive Paints”. When the paint is subjected to heat it will react. In the case of an intumescent paint when subjected to temperatures exceeding 120°C the paint will intumesce (swell up to 50 times the thickness of the paint) and form a carbon layer (char) which thermally insulates the timber substrate. This in turn slows down the timber char rate and increases the burn through time. We offer products to fire protect timber cladding on buildings which require a Euroclass B or Class 0/1 surface spread of flame. These products are used slow down the spread of fire in a building which aids peoples escape. In a fire it is critical that the structural timber frame and cladding internally and externally of the building is protected correctly so that the timbers do not burn/char away leading to premature failure.

We have made a video showing intumescent varnish at work on some timber, which you can view here.

In Summary, intumescent timber paint thermally insulates structural and NON structural timber in a fire, slowing down the spread of fire and stopping premature collapse of the building.

Application of Intumescent Paints for Wood

Please follow the manufacturer’s instructions and spreading rates when applying intumescent paint to timber.

Do I Need a Topcoat?

With clear wood intumescents a topcoat is needed to stop them turning milky in colour. This happens when the intumescent reacts with water

For all external wood jobs, two coats of a solvent-based topcoat are necessary to protect the intumescent from the environment.
