Guide to painting stove pipe or flue pipe

Stove pipe and flue pipe need a clean steel surface and a true high heat coating, because normal decorative coatings cannot cope with repeated heating and cooling cycles.

What do you need to paint stove pipe or flue pipe?

Cleaning and degreasing

Mipa silicone remover in liquid format is the main cleaning choice for larger steel surfaces, while the spray is useful for smaller details, seams and awkward shapes before sanding or coating.

Contour sanding support

MP Hand Block Soft helps abrasive paper follow round pipe, curved stove surfaces, trim edges and shield profiles without cutting flat spots into the metal.

Brushable high heat coating

Mipatherm liquid coating is suited to larger steel surfaces that need a heat resistant silver or black finish and controlled application by brush or spray equipment.

High heat aerosol finish

Mipatherm Spray 400 ml is the quick aerosol method for smaller heat loaded steel parts, detail areas and local repairs in matt black or silver.

How to paint stove pipe or flue pipe

  1. 1
    Cool and strip the loose surface

    Work only on a fully cool pipe. Remove loose paint, rust, scale and soot so the new high heat coating bonds to firm metal.

  2. 2
    Clean before sanding and after sanding

    Use Mipa silicone remover or the spray format to remove grease, oil and contamination. Clean again after sanding so dust and residue do not sit under the coating.

  3. 3
    Sand with controlled pressure

    Use MP Hand Block Soft with suitable abrasive paper to key sound metal and feather any remaining firm paint edge without gouging the shape.

  4. 4
    Apply thin high heat coats

    Use Mipatherm or Mipatherm Spray in thin, even coats. Heavy wet coats make heat coatings more vulnerable to bubbling, slow curing and surface marks.

  5. 5
    Let the coating cure with heat gradually

    Allow the painted pipe to dry before heat exposure, then bring the temperature up gradually during the first use with good ventilation.

Which stove pipe paint format should you choose?

Choose liquid coating for larger steel areas

The liquid Mipatherm format is the better method when the part is too large for efficient aerosol work or when a more deliberate brush or spray equipment application is preferred.

Choose aerosol coating for smaller detailed parts

Mipatherm Spray suits pipe sections, trims, shields and hard to reach edges where thin, even coats from a can are practical.

Keep normal paint away from hot surfaces

Standard decorative or automotive paint is not the right finish for metal that becomes very hot during use; use the high heat coating method instead.

Technical details

  • Mipatherm and Mipatherm Spray are heat resistant special coatings for steel substrates exposed to high temperatures, with stated resistance up to 800 °C.
  • Mipatherm Spray is applied in 2 to 3 coats at about 20 to 30 cm spray distance, with a target dry film thickness of 15 to 20 µm.
  • Mipa source information lists 5 to 8 minutes flash off between coats and at least 10 to 15 minutes before the first heat exposure for the aerosol format.
  • Optimum film properties are reached after the first controlled heat exposure, so freshly coated parts should be handled carefully before curing.
Practical suggestion

Paint a small test area on old stove pipe first when old coating remains firmly attached. The test area shows whether the surface is clean, keyed and compatible before the full pipe section is coated.
