Rust-Oleum Heat Resistant Paint 750°C Aerosols, heat resistant coatings based on a silicone modified alkyd resin.

Self-priming, Rust-Oleum Heat Resistant Paint 750°C should not be applied on primers or coatings, which are not heat resistant.

Recommended use (7715/7778 Aerosols):

Should be used on new, bare steel, blasted steel or light rusted steel surfaces or properly prepared painted substrates alike barbecue grills, fireplace equipment, space heaters etc. Intended for small maintenance jobs or for touch-up, providing heat resistance up to 750°C (= 1380°F) dry heat (short term peak resistance) in sheltered or interior environments.

Consumption

Practical consumption depends on many factors such as porosity and roughness of the substrate and material losses during application.

Application

Surface preparation

Remove dirt, grease, oil, loose rust and all other surface contaminants by appropriate means. Sand intact coatings to roughen the surface slightly. The surface must be clean and dry during application.

Application conditions

Only apply if the air and surface temperatures are between 5 and 35°C and the relative humidity is less than 85%. The temperature of the coated surface must be at least 3°C above the dew point.

Application by aerosol

Remove cover cap and shake vigorously for at least one minute after the rattle of mixing ball is heard. Shake frequently during use.

Hold can approx. 30 cm from surface. Use back and forth motion keeping can parallel with surface.

Ensure that can is in motion when spray button is pressed to avoid runs and sags.

Apply several thin layers at a few minutes interval to achieve adequate coating thickness.

After use turn can upside down and press spray button for 2 - 3 seconds to clean valve.

Application to Stainless Steel;

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;

The surface should be thoroughly cleaned and degreased using Rust-Oleum Pre-Paint Cleaner, followed by hand or machine abrasion to impart a scratch pattern to the surface. Use non-metallic abrasives, bonded fibre machine or hand abrasive pads - Do not use high speed rotational sanders.

We must stress the importance that this abrading process actually results in a profiled surface that can be seen by eye and felt by fingertips. Trying to achieve such a surface onto stainless steel will require extensive effort and it must be noted that this will still not ultimately equal product performance which would be achieved by the blast cleaning method referenced above.
