What is the ideal height for my plinth plaster?

This is how the base area should be designed

In buildings with a basement, the plinth area is not right at the bottom, but almost. Below that only comes the perimeter zone, for which completely different rules apply. But even here, directly above the ground, a lot of water and dirt can be expected.

The mechanical loads are therefore high, but the base plaster and its substructure should be well equipped. In addition, the important rule applies that the house base preferably jumps back behind the wall plaster above. It is possible that both are on the same level, but it is better not to let the plinth plaster protrude.

If part of the base is located in the ground, this area needs a covering of sealing slurry for protection. Line your home with a gravel bed for quick drainage of rainwater. Any paving stones should be laid with a slope away from the house wall.

Looked closely: the height of the plinth plaster

The official recommendation applies to apply the plinth plaster at least 30 centimeters above the ground. Most building bases, however, are justifiably a bit higher.

50 to 100 cm in height are not uncommon, because after all, the rainwater usually splashes higher than just 30 centimeters. That is why we advise you to plan the plinth of your house a little more generously and perhaps set it off in a nice color.

A base coating consists of these layers

Finally, we would like to inform you about which layers a base coating usually consists of. So you have an idea of ​​how complicated the design of this outside wall area is.

  • At the very bottom, of course, is the actual wall surface.
  • An insulating material is attached to it, which also repels water.
  • Next comes an adhesive or a filler (€ 5.70 on Amazon *).
  • A reinforcement, which usually consists of fabric, is placed on top.
  • Many craftsmen apply a primer to it for better durability.
  • Now the plinth plaster finally follows as the penultimate layer.
  • The finish is the base color, which should also be very robust.
If your base is protruding, the protruding surface needs special protection. Cover them with metal sheets or apply a special protective coating.
