Guide to coating metal facade panels

Metal facade panels need a clean, consistent coating approach because large exterior surfaces show roller marks, uneven gloss and poor edge preparation quickly. The specified 2K PU method focuses on prepared facade panels where a semi-gloss protective finish is required.

What do you need to coat metal facade panels?

Cleaning and degreasing

Mipa silicone remover in liquid or spray format removes silicone, grease, wax and weathering residue before the facade panel is keyed and coated. Clean edges and overlaps carefully.

2K PU facade coating system

Mipa PU 250-50 with Mipa PUR Plus Hardener A60 and Mipa 2K Thinner Normal V 25 gives the specified semi-gloss 2K PU coating method for prepared metal facade panels.

Colour group selection

Mipa PU 250-50 price groups I, II and III represent the colour group choices for the same facade coating role. Choose the shade group that fits the building finish.

How to coat metal facade panels

  1. 1
    Wash and degrease

    Remove exterior dirt first, then clean with Mipa silicone remover so grease, wax and silicone do not remain below the coating.

  2. 2
    Prepare the panel surface

    Remove loose coating, corrosion residue and chalky material. Key the facade panels evenly so the 2K PU coating has a stable surface.

  3. 3
    Protect joints and borders

    Mask windows, trim, seals and wall edges. Keep panel overlaps and drainage details clean rather than flooding them with coating.

  4. 4
    Apply the 2K PU method

    Use Mipa PU 250-50 with Mipa PUR Plus Hardener A60 and Mipa 2K Thinner Normal V 25 according to the coating information for the chosen application method.

  5. 5
    Control the finish across panels

    Work in manageable sections so the semi-gloss appearance stays even from panel to panel and edges do not dry with heavy build.

Which facade coating method should you choose?

Use the PU method for full panels

Choose Mipa PU 250-50 when the job is a prepared metal facade panel that needs a consistent semi-gloss protective coating across a larger surface.

Use the right colour group

Choose price group I, II or III based on the required colour. The coating role stays the same while the colour group changes.

Plan large surfaces carefully

Facade panels show overlap marks and uneven film build easily, so divide the work into controlled sections before applying the coating.

Technical details

  • Mipa PU 250-50 provides the 2K PU semi-gloss finish for prepared metal facade panels.
  • Use Mipa PUR Plus Hardener A60 and Mipa 2K Thinner Normal V 25 with PU 250-50 so the 2K coating can be applied and cured correctly.
  • Silicone remover in liquid or spray format removes grease, silicone, wax and handling residue before sanding and coating.
  • The 2K PU coating method is the right guidance for facade panels because larger exterior surfaces need a controlled semi-gloss finish.
Practical suggestion

Large facade panels reward preparation. Clean, key and mask a controlled section before mixing coating material, then keep a steady edge so adjacent panels do not show different gloss or build.
