Facade damage, wooden facades
The paint on wooden facades, as well as all other exterior painted surfaces, degenerates over time (see figure 1). Which allow
water to penetrate the wood and eventually destroy it. The more sunlight and/or water, the painted surface is exposed to the faster
the process. It is usually the worst at the bottom because all the water that hits the wall above the surface sooner or later runs down
there, but sometimes also because it splashes up from the ground or from plants nearby.
Picture 1. Paint that is degenerated.
Facade damage, plastered facades
Even plastered facades degenerates over time (see figure 2 & 3). The more water that ends up on the façade,
the faster it goes. Which means that finally the plaster is destroyed. First in the bottom, but often also at the
top. The more the plaster releases the more water comes in between plaster and wall, and the faster the
plaster releases further.
Picture 2- 3. Plaster damage. The plaster has come loose from the wall and are just joined together through the outer
layer of spray plaster. The surface bulges out a bit and if someone tests with a knife tip on the surface it goes through.
The stage before this is that it sounds muffled when knock on it with the knife, but the tip does not go through. When
it collides with perfectly healthy plaster, however, the sound is a lot less muffled.
