Heat Resistant Paint
When choosing a paint that is heat resistant, make sure you find a manufacturer that has been around for a while with a solid reputation. Dampney Company Inc. has been around for 96 years. They offer industrial architectural and residential paint and coatings for multiple applications. Typical uses for heat resistant paints include wood burning stoves, smokers, bbq's, fire pits, mufflers, exhausts, engine blocks. What makes Dampney's heat resistant paint unique? They offer custom colors and multiple packaging including aerosols, quarts, gallons, five gallon and 55 gallon drums. Dampney's customers include homeowners, contractors, manufacturers, OEM's, paint shops, auto restorers and some of the largest corporations in the world.
The surface preparation, application and use of a primer is a function of the adhesion of the paint. What painters, manufacturers, applicators, smoker/BBQ pit manufacturers all differ based on their operation, baking capabilities, cost of primer and limitations to sand blasting. Acetone, Xylene or MEK should be the only solvents we suggest when cleaning the metal surface prior to painting with a high temperature paint/coating.

Surface preparation
To ensure optimum long-term coating system performance, surfaces must be clean, dry and free from dirt, oil, grease, salts, welding flux, mill scale, rust, oxides, old paint, corrosion products or other foreign matter
1. Remove all surface imperfections that will induce premature coating system failure. Chip or scrape off weld splatter. Grind down sharp and rough edges.
2. Abrasive blast surface per specification SSPC-SP 10, “Near-White Blast Cleaning”, or per NACE Standard No. 2 to a profile depth of 1.5 - 2.0 mils maximum, with a 1.5 mil anchor pattern being ideal. Abrasive used in blasting should be selected carefully from materials of mesh size required to produce the desired anchor pattern.
3. If abrasive blasting is not permitted, prepare surface by power tool cleaning per SSPC-SP 11. Use 3M brand “Heavy Duty Roto Peen”, type C flap wheel cleaning system mounted on an air-driven motor. This method will provide a surface equivalent to that provided by commercial blast cleaning per SSPC-SP 6, including the desired surface profile.
Feather out all edges of adjacent painted surfaces after completion of surface preparation operations and prior to application of the first coat of paint
