Increase your fire protection with fire retardant paint

Everyone is concerned about the risk of fire, but thankfully there are fire safety coatings designed to provide extra protection and some peace of mind. Fire retardant paint works by increasing the threshold required to start a fire and preventing ignition and slowing the rate at which flame spreads.

Fire retardant paint emits gases when exposed to extreme heat which dilute the flammable gases feeding the fire, dampening it and reducing its power.

These coatings are usually applied to substrates which are likely to burn in the event of fire, such as wood or foam, and can be applied to walls, floors, and ceilings in any space.

Improve fire safety at home with fire retardant paint

Fire retardant coatings are becoming more and more popular among home owners who are concerned about the fire safety of their houses. There are fire retardant paints for interior walls, ceilings and floors as well as for exterior walls.

Bear in mind that these coatings are not suitable for fire places, BBQ’s etc. They require high temperature coatings which do not react with heat but rather protect the surface from it.

Wooden surfaces can receive protection with fire retardant varnish and paints. These can be applied to treated and untreated wood just like paint, using a brush, roller, or spray, and come in a variety of finishes.

Fire retardant varnish for wood is a transparent or translucent system that preserves the natural appearance of wood while protecting it from flames. It is available for interior and exterior applications. It is suitable for example for garden furniture, interior stairs, timber cladding and decking.

Upgrade to a fire door with fire retardant paint

Doorways and exits become very important in a fire, both for escape and for isolating and controlling the flames. It is possible to upgrade doors to fire doors, by applying an all-in-one fire door paint upgrade kit.

These combine the protection of fire retardant paints with fire resistant paints to provide the highest fire safety.

For fire doors in general there are two requirements:

  • The door must be solid, not hollow
  • It needs to be at least 35 mm thick

If you want to coat a door that consists of sunken panels, the panel thickness matters. Veneers can be applied, but the door must be at least 9mm thick at any point to use the kit. Fire door paint is available in different colours, or can be applied in a clear varnish.

Fire retardant paint for steel and concrete structures

Intumescent paints offer better protection for steel, so fire retardant paint is not common on steel surfaces. Fire retardant paint is not used as the only fire protective layer for steel, instead it is combined with fire resistant (intumescent) paint.

Concrete is a material which does not burn easily, however, fire will eventually weaken it. Fire retardant paint is not often applied to concrete, because there is little need for it. However, when additional fire protection is needed, the most commonly used coatings are intumescent, as the protection provided is more appropriate.

Layer fire protection systems with fire retardant paint

The best fire protection system insulates the substrate and damps flames.

When maximum fire protection is required, you can combine the strengths of a fire retardant paint with a fire resistant paint (intumescent paint). The two coatings protect from fire in different ways:

  • fire resistant paint responds to extreme heat by expanding to form a heat insulating layer between the fire and substrate
  • fire retardant paint is used as the top coat, damping the flames and preventing the intumescent paint from activating, extending the time of protection and preventing the fire spread

When combined, these two coatings give a substrate its best chance at withstanding a fire.

Remember to get your fire retardant paint job certified

One thing to keep in mind regarding fire retardant paint is certification: whether you apply it yourself or let the job done by a professional, you should make sure you have proof of the application and the receipts of the products used. Certification of your fire retardant paint application will help with insurance policies or if you ever need to claim damages.

Many applicators and coating manufacturers  provide a certificate for fire retardant coating and application. If the applicator does not provide certification, you should at least have the proof of purchase of the product and a fire protection certificate from the coating manufacturer.

British standards & regulations for fire retardant paint

When looking around for fire retardant paints you will see that they are given either a class 1 or class 0 rating. These relate to the British Standard for fire resistance, outlined in BS 476. Class 0 is the highest level of protection, usually required for fire protection systems in corridors and fire escapes

Fire retardant paints are tested for fire protection in half hour intervals. Which is why you see “30 minute protection”. A 60 minute fire retardant should prevent the spread of fire for an hour, giving precious extra time to deal with it. These guides might change depending on the substrate, remember to always read the specifications for any product.
