An exterior plaster is usually not freely selectable in the color

Technically possible is almost every color for exterior plaster. If a colored plaster in the desired color is not available, a brushable plaster can be selected. In addition to the individual aesthetic requirements and circumstances, building law and the so-called light reference value must also be taken into account.

Aesthetic and optical fundamentals

The exterior plaster on a facade is the dominant design feature of a building. The exterior plaster is dyed or painted. This monochrome or multicolor variants can be implemented. Both a mineral plaster and a plaster can be painted over.

As variants, the following variants are popular and common:

  • Monochrome complete plaster
  • Remote window and door borders
  • Offset socket plaster

Roof and facade

In the aesthetic decision for the color first the overall appearance of the building plays the biggest role. The following structural specifications should be considered:

  • Color of the roofing
  • Type and characteristics of the roof covering (bricks, pans, thatch, metal, plastic)
  • Color and material of the window and door frames
  • Number and size of the soffits
  • Bay window, building form, stems and ledges
  • Color and appearance of the windows (panorama, bridge glazing, reflectance)
  • One- and multi-color

Windows and doors can be set up with borders in different colors. The same applies to the base, which can get its own color in the desired height. It makes sense to study the general color theory. The effect of complementary colors and contrasts can be tested well in advance by online configurators.

Texture of the surfaces

On rough plaster types such as structure plaster and scratching plaster, colors have a different effect than smooth or rubbing plaster.

Lightness value

The higher the lightness value of the plaster, the later and less stress cracks appear. The value describes the intensity of the color resulting from the color particle concentration. As the value increases, the visibility of cracks decreases.

Development plan and regulations

Almost everywhere a local development plan applies, which also restricts the color of the building or the exterior plaster. Formulations such as "Facade may only be provided with bright mineral plaster" are not uncommon. While extreme colors exclude the pink, blurred terms such as "bright" are commonplace.

Tips & Tricks

If there is room for interpretation between the development plan and your color choice, define colors according to RAL and ask the building authority in writing.
