Heat resistant paints are designed to withstand high temperatures of up to 750°C, which makes them ideal for use on BBQs, fireplaces, chimneys, pipes, engines, exhaust pipes, log-burners and many more metal/metallic items requiring heat proof treatment. Heat resistant spray paints are also available at Rawlins Paints, in assorted colours and from the UK's leading manufacturers.

How Does Heat Resistant Paint Work?

It’s important to understand the difference between heat resistant paint and fire proof paint. Although it could be easy to confuse the two, heat proof paint is a surface coating and does not protect the material in the event of a fire.

High temperature paint is designed to not break down at very high temperatures, so they can be safely used for ovens, cookers, engines and pipes that need to regularly be at high temperatures of up to 750°C.

Fire retardant paints, on the other hand give off an inert gas to slow down and stop the spread of fire on the surface and intumescent paints provide an insulating barrier by swelling up to 40 times their original thickness. Please see here for the fire retardant paints stocked by Rawlins Paints.

Brands

We have the following heat-resistant paint brands in stock: Blackfriar, Coo-Var, International (including Intertherm 50), Jotun and Rust-Oleum. All of these brands also include anti-corrosion products.

Heat Resistant Paint Colours

The most common colours for these heatproof paint products include black and silver (also referred to as aluminium). Some heat resistant coatings we stock are also available in white, grey, red oxide and orange. If you’re struggling to find a specific heat resistant paint colour, please contact us.

How to Apply Heat Resistant Paint

One of the more popular ways to apply heat proof paint is via spray devices. Jotun's range can be applied with spray guns, also available at Rawlins Paints. Jotun Solvalitt Alu is heat proof for temperatures up to 600°C and acts as a heat resistant primer, mid-coat or finish-coat on steel. Although lots of our products can be used as heat resistant spray paint, there are also plenty of brushed heat resistant coatings, which can also be applied with a traditional roller if preferred.

Very High Heat Resistant Metal Paint

Various metal structures, surfaces and substrates that get up to high temperatures require painting, and finding the best heat resistant paint for your needs is key to ensuring the finish is appropriate for use.

If you’re looking for high heat paint for barbecues, boilers, exhaust pipes and other smaller interior surfaces, then have a look at our Rust-Oleum and Blackfriar heat resistant paint.

Rust-Oleum Heat Resistant Paint 750°C can be used on bare metal or slightly rusted surfaces and provides a heat resistant coating. Rust-Oleum HR protects up to a dry heat of 750°C and can be applied inside or in a sheltered outdoor environment. Perfect for engines, barbecues, vents and pipes - it’s available as an aluminium heat resistant coating or in black satin-matt.

Blackfriar High Heat Resistant Paint is great for fire grates, barbecues, chimneys and radiators and can withstand heat up to 600°C and is ideal if you’re looking for a black heat resistant paint with a matt finish.

Enamel Paint

An enamel heat resistant coating, Coo-Var Heat Resistant Satin Black can be used on surfaces that need to withstand heat up to 600°C and is ideal for areas that frequently get hot. It can be used as a single coat for hot pipes, radiators and fire surrounds.

Another high quality heat resistant enamel paint is Teamac High Temperature Aluminium Paint. Teamac can be used at temperatures up to 450°C and is applied with a brush or roller. The satin finish is ideal for metal and can also be used as a single coat on fire surrounds and hot pipes.

Aluminium Paint

With a heat resistance of up to 250°C, Jotun Aluminium Paint HR is perfect for engine parts and exhaust pipes. Its aluminium finish coating can be used as a heat resistant primer, mid coat or top coat and can be used on carbon steel and aluminium substrates if they’re properly prepared.

Industrial Heat Retardant Paint

Many heat resistant coatings also have an anti-corrosive finish, which adds more protection for the surface. Rust-Oleum 4200 Heat Resistant Primer can be used on incinerators, stacks, kilns and other very high temperature surfaces that are prone to rust. This heat proof primer should be used on new, bare steel or blasted steel underneath Rust-Oleum 4200 Heat Resistant Topcoat.

If you’re looking for protection from corrosion on stainless steel industrial surfaces, Jotun Jotatemp 650 is ideal. Jotatemp 650 works specifically on surfaces that need to withstand extreme high and low temperatures, between -185°C and 540°C and can be applied directly onto a surface that is at 400°C.

For large aluminium surfaces, such as offshore structures, petrochemical and chemical plants and power stations, International Intertherm 891 is a good choice. Intertherm 891 is a general-purpose heat resistant paint that gives a silver finish as it’s coloured with aluminium flake. It can be used as an industrial maintenance coating on steelwork with a temperature ranging from ambient to 315ºC.

Fireplace Paint

When you’re installing anything that involves fire, you need to think about preparation and safety. A fireplace can make a stunning addition to any room, adding instant impact and a homely feel. Multi Fuel Stoves are also a very distinct type of fireplace, which make a statement in any living room or entrance hall.

Installing a Multi Fuel Stove

Before starting your fireplace project, it is important to check your fireplace is suitable for the stove you intend to buy/have installed. If you are using a professional installer for a new stove, they should advise you on which stove to buy and what regulations must be met for your property and fireplace.

Painting a Fireplace - Problems

Fireplace recesses can’t have anything combustible in them, so materials like stone and brick are fine but if you want that smooth plastered finish you need to make sure you use special fire and flame retardant versions of the board and skim.

Painting your recess creates additional problems. The area immediately surrounding your fire will get hot when the fire is in use. This will discolour normal paints and eventually cause them to crack, flake and peel off the surface. Unfortunately, fire retardant paint is not ideal either. These paints are designed to react in a fire to protect the surface they are applied to and once they have done their job they must be removed and re-applied to ensure protection is maintained.

If the stove has not been fitted correctly, it is not advised to decorate around the fireplace with a product unsuitable for the task.

Painting a Fireplace and Around a Stove - Solutions

The best advice we can give to paint fireplace recesses is to not do it if you are unsure whether the stove has been installed correctly, but if you know it has been, we suggest using a flame-retardant topcoat. These types of products are used to finish fire retardant paint systems and come in most conventional paint finishes – matt emulsions, eggshell, gloss, etc. and can usually be bought in a wide range of colours.

By using a flame-retardant topcoat you can decorate the area safely. Although they are not heat resistant, they will withstand temperatures up to around 70-80°C comfortably and you can be safe in the knowledge that you are not painting the surface with something combustible.

With a correctly installed stove, the temperature on the wall shouldn’t be more than that from a standard radiator (approx. 60°C), and for this job the following products in this post are suitable.
