Is Hammerite Heat Resistant?

There are lots of reasons for wanting to know whether Hammerite is heat resistant, the most obvious one being you want to use it in an area that gets hot. And with my award for expert deductions safely in my back pocket, we can move on to the matter at hand, is Hammerite heat resistant?

Is Hammerite Heat Resistant

Yes, regular direct to rust Hammerite is heat resistant and has been used on heat-sensitive parts by people like car detailers with no problems. However, you cant use it in areas of extreme heat like BBq’s and Chimeneas. For this Hammerite sell a specialist heat resistant paint that can stand temperatures up to 600°C

Regular Hammerite

Good old direct to rust Hammerite is a heat resistant paint in its own right. Just don’t go expecting it to work miracles.

People involved in car modifications and restorations often used Hammerite on engine bay parts and brake callipers, all of which can get pretty hot, the regular Hammerite seems to work just fine.

And there comes the annoying part of this tale. It is all based on what seems to work and how it works out in practice. This is because Hammerite doesn’t give an official working temperature range for their standard paint, so it all comes from hearsay and know-how.

High Heat Paint Aerosol

Hammerite High Heat Paint Aerosol is a durable, heat resistant protective finish specially formulated to withstand temperatures up to 600ºC, making it ideal for fire surrounds, guards and boilers. Developed to resist cracking and flaking. Available in 400ml aerosol.

BBQ Aerosol

Hammerite Barbecue Paint is specially formulated for use on the exterior of metal barbecues. It also resists cracking and flaking. It resists temperatures up to 600°C.

Now I know what your next question will be, what is the difference between the High Heat Hammerite paint and the BBQ Hammerite paint. And truth be told, I really don’t know. They both are available in black only and both resist up to 600°C.

Perhaps I should buy them both and do some testing? I will add that idea to my list of potential experiments.
