The facade reinforces as an effective remedy against cracks

Reinforcing fabrics are there to effectively cover existing cracks and prevent new material stresses. They are used when a new plaster is laid over an old one or a thermal insulation composite system is applied. But how can the fabric be connected to the ground? And can I be sure that my façade will never crack again?

Reinforcing facade: This function fills the fabric

It is not clear to everyone what a good-sized fabric laid on the facade should be good for. Here is the explanation: It absorbs the resulting tensile stresses when the cleaning system swells and fades over time.

Especially where different materials are stacked on top of one another, there are often such strong tensions that new cracks are created - or old cracks are transferred to a freshly applied plaster layer. The reinforcement decouples the working layers.

But the fabric does not work on its own: it is embedded in a so-called reinforcing plaster, which is applied relatively thinly. This material develops a certain flexibility and has a compensatory effect when tensions occur.

How effective is the facade reinforcement?

There is no 100 percent protection against cracking, but those who have their façade reinforced reduce the risk to a minimum. The reinforcement can also serve to provide different surfaces with a continuous layer of plaster, without having to install a joint.

For example, if wooden beams visible to the outside are to disappear seamlessly under a plaster, the use of fabric is definitely worthwhile. Otherwise, you have to take into account the impending cracks!

This is how the reinforcement of the facade works

When it comes to facade reinforcement, there are a few things to keep in mind: With our brief instructions, you can avoid the worst of fuddles and can look forward to a nice result:

  • Reinforcements can be applied over the whole area or over part of the area.
  • Apply about 10 mm of reinforcing plaster to the clean wall
  • Insert the fabric completely wrinkle-free.
  • Apply about 5 mm wet-on-wet with a smooth plaster over it.
  • The overlap of the webs should be about 10 cm.
  • For material transitions, lay 20 cm in the adjacent area.
  • Use glass grille strips on window and door openings.

Only when everything has dried well, a further treatment of the area may take place. Now you can decorate your façade with decorative plaster and paint it as you like!

Tips & Tricks

If you apply the second layer of reinforcing plaster, the first layer must not show any skin formation! So do not edit large areas, but proceed in sections.
