Stove bodies, flue pipes and boiler enclosures reach temperatures that ordinary radiator enamel cannot survive. Purpose-made heat-resistant coatings are formulated and rated for specific temperature bands, and matching the rating to the actual surface temperature is the whole job.
A coating rated for moderate warmth on a boiler casing will scorch, discolour or flake on a stove flue that runs far hotter. We check the manufacturer's stated temperature band against the actual surface, not just assume any product labelled heat-resistant will do.
Old carbonised paint, rust and residue need removing back to sound metal before a new heat-resistant coating is applied. Painting over flaking existing coatings on a stove body is a common cause of patchy, early failure once the appliance is lit again.
Flue integrity, chimney lining and appliance safety sit outside a decorating scope. Where we suspect a flue or appliance issue beyond the coating itself, we say so and recommend the client involves a qualified heating engineer before further work proceeds.
No — ordinary black paint will scorch and discolour at stove operating temperatures. A properly rated heat-resistant coating matched to the surface temperature is needed.
The coating needs to cure fully before first use, and many products also specify a gentle first firing to cure the finish properly — we follow the manufacturer's guidance rather than guessing.
We are decorators, not heating engineers, so we flag any concerns about the flue or appliance for a qualified engineer rather than assessing it ourselves.
Tell us what appliance and surface you need coated and we will confirm the correct heat-resistant product.
Heat-resistant coatings only perform when their rated temperature genuinely matches the surface, and appliance safety stays outside a decorating scope.
