Self-priming, Rust-Oleum Heat Resistant Paint 750°C should not be applied on primers or coatings, which are not heat resistant. Blast cleaning to achieve an appropriate surface profile is the best method of preparation for stainless steel, however as Rust-Oleum Heat Resistant Paint 750°C is for general/consumer use and not professional or industrial applications we can assume that in the majority of instances blast cleaning will not be achievable. The principle of requiring a profiled surface to assist in the adhesion of the paint system remains, and so preparation advice for smaller projects that still wish to attempt it would be as follows; If the fireplace is active then you will need a paint to resist temperatures that are higher than a normal, decorative topcoat can handle, such as our fireplace surround paints that perform up to 300°C.

All metal surfaces should be clean, dry, and free from grease, oil, and other contaminants that could affect adhesion. Use a degreaser before de-rusting. De-rust according the manufacturer's instructions - usually through mechanical or blast cleaning as hand washing will not clean the surface sufficiently.When it comes to colour, the current most popular options are white and grey paint for an ultra modern and clean look, ideal for frequently changing rooms. A paints finish will affect the overall appearance, feel, and durability of your paint, so it’s important to understand the differences to achieve your desired aesthetic. Matt paint has a non-reflective finish, chalk paint has a matt, shabby-chic finish, while eggshell paint is low-sheen and durable. Additionally, satinwood paint has a subtle sheen and is great for interior woodwork, while gloss paint is high-shine and ideal for exterior woodwork and metal surfaces. Tikkurila Muuri is a heat-resistant breathable paint recommended for use on firewalls, fireplaces and similar interior wall surfaces where the surface temperature may rise above normal. Surface defects and loose pointing should be filled in, with any visible signs of organic growths treated with mould remover.

If necessary, clean the surfaces with a dry brush, mop or dust cloth after a minimum of one month after coating Yes the smell most likely is the paint. From what you have said the fire has not been installed correctly in the space it is in and is getting the surrounding walls and surfaces too hot, this is also the most likely cause of the yellow blistering of your first paint (not mould). The fire is heating up the painted surfaces and causing them to discolour (yellowing) and then getting so hot the paint is blistering. The new paint you’ve used is obviously suffering from the same but the smell most likely will be because the paint is newer and being mould resistant probably has some additional contents to combat mould that may be giving off the smell under extreme heat.The surface to be painted must be clean, dry and sound and the temperature of the air/surface should be a minimum of +10°C with a relative humidity of below 80% Once dry, the surface should now be prepared to paint over with a suitable topcoat. If your fireplace still functions then you will require a heat-resistant primer and topcoat, such as Tikkurila Murri.
