The paint should be applied over the material with the minimum amount required so as to avoid saturating the material..

How long does intumescent paint last?

Intumescent coatings can be specified for internal and external exposure, giving up to two hours fire resistance for shop or site application. Durability (i.e. life to first maintenance) of up to 25 years or more can be achieved with careful specification and application controls.

How long does fire retardant paint last?

Is intumescent paint flammable?

This non-combustible meringue type layer insulates the substrate and increases the time it takes for the fire to penetrate through. … Intumescent and fire retardant coatings should not be confused with heat resistant paints, which perform a different function.

How much does intumescent paint cost?

As intumescent fire resistive coatings can be quite expensive ($4 to $12 per square foot, depending on the application and required rating), measuring the coating thickness can play an important role in controlling the application costs. Proper adhesion is also essential to the effectiveness of these coatings.

What does the word intumescent mean?

At what temperature does intumescent paint react?

120°CIntumescent paint reacts when its temperature attains or exceeds 120°C, and the process results in a soft charring effect at its surface (which insulates and reduces transmission of heat into the substrate) and the release of water vapour (which helps to cool the substrate).

Does intumescent paint provide integrity and insulation?

Yes, intumescent coatings can usually provide the necessary structural fire protection to the steel beam/section. … For any further guidance on fire integrity and insulation criteria consult Building Control.

Is latex paint fire retardant?
