Heat resistant paint.
Heat resistant paint turns up on shopping lists for radiators, wood-burning stoves, flue pipes and fireplace surrounds, and it's easy to grab the wrong tin. Ordinary emulsion or gloss will scorch, discolour or blister the moment real heat gets to it, so the right heat resistant paint — and the right preparation — matters more than the brand on the label.
What "heat resistant" actually means.
Heat resistant paint isn't one product — it's rated for different temperatures depending on the job. Radiator and towel rail paint is usually rated to around 120-150°C, enough for a domestic heating system running flat out in winter. Paint for wood-burning and multi-fuel stove bodies, flue pipes and fire surrounds needs to cope with much higher heat, often 500-600°C or more, and is formulated quite differently. Using a radiator-grade paint on a stove, or vice versa, is one of the most common mistakes we see on site — check the rated temperature on the tin before you buy, not just the words "heat resistant" on the front.
Where it's used around the home.
The obvious job is radiators and heated towel rails, which most households repaint at some point as part of a general redecoration — old radiator paint yellows and chips over the years. Wood-burning and multi-fuel stoves, their flue pipes, and the brick or stone surrounds immediately around them also need specialist heat resistant paint, as do some cooker splashbacks close to range ovens. B&Q and other trade suppliers stock a range of aerosol and brush-on heat resistant paints, from matt black stove finishes to satin radiator enamels, and aerosols are popular because they give a smoother finish on awkward shapes like stove doors and pipework.
Prep and application make or break the finish.
Heat resistant paint needs a properly prepared surface to bond and survive repeated heating and cooling — that means bare, degreased metal with any rust or flaking paint removed, and often a specific heat resistant primer underneath. Thin coats matter more than usual here; a thick coat is more likely to bubble or craze the first time it gets hot. Most heat resistant paints also need to be "cured" once fitted, which means running the appliance gently — a small, cool fire in a stove, or the heating on low for a radiator — before it's used at full temperature, so the paint hardens properly instead of scorching.
What we can help with.
As decorators, radiators, towel rails and fire surrounds are jobs we take on regularly, usually alongside repainting the room around them so everything finishes to the same standard. For stove bodies and flue pipework we'll always be honest if a job needs a specialist installer rather than a decorator — safety and building regulations matter more there than paint.
