Paint exhausts, silencers and heat shields

High heat exhaust coating

Guide to painting exhausts, silencers and heat shields

Exhausts, silencers and heat shields need a coating method built around heat, surface contamination and careful masking. This guide focuses on cleaning, keying and applying Mipatherm to suitable external hot parts without coating sensors, joints or functional contact surfaces.

What do you need to paint exhausts, silencers and heat shields?

Degreasing cleaner

Mipa silicone remover in liquid or aerosol format removes grease and residue before the external hot part is keyed.

Sanding sponge

MP Sanding Sponge helps create a dull surface on accessible exhaust shields, silencers and heat-exposed metal before coating.

Mipatherm coating

Mipatherm in liquid or aerosol format creates the heat-resistant coating stage for suitable prepared exhaust parts, silencers and heat shields.

How to paint exhausts, silencers and heat shields

  1. 1
    Work on cold parts only

    Let the exhaust part cool completely and remove loose rust, dirt and flaking old coating before cleaning.

  2. 2
    Degrease and key

    Clean with silicone remover, then sand the external surface until it is stable and dull.

  3. 3
    Mask sensitive areas

    Protect sensors, joints, clamps, rubber mounts, threads, contact faces and any area that should remain uncoated.

  4. 4
    Apply Mipatherm

    Apply the heat-resistant coating in controlled coats and follow the drying and heat exposure instructions before the part returns to service.

Which high heat coating format should you use?

Aerosol for smaller hot parts

Choose Mipatherm Spray for heat shields, small silencers, brackets and shaped external parts.

Liquid format for larger surfaces

Choose liquid Mipatherm where a larger prepared hot surface or spray-gun application is more suitable.

Technical details

  • Mipatherm is for external heat-exposed surfaces; it is not an internal exhaust repair or leak repair product.
  • The surface must be stable, dry and free from loose rust before coating.
  • Heat-resistant coatings must be allowed to dry and handle heat according to the technical information before heavy use.
Practical suggestion

For old exhaust parts, preparation decides the result. Loose scale, oil and failing old coating should be removed before any new heat-resistant coating is applied.
