However, a developer told us that the plaster facade is made of synthetic resin and is therefore not absorbent and more weather-resistant. Accordingly, it does not need to be painted in the future.
Hello!
More weather-resistant than what? At best, you can infer that it needs to be painted less often. The paint on my car is also not absorbent – does that mean I no longer have to wash it?
By the way, Google says:
An essential factor is the formation of dew when the temperature of the plaster surface falls below the outside air temperature (at night due to the radiation of heat into space; regularly visible on cars). Since drying occurs only slowly on water-soaked synthetic resin plasters, a climate more favorable for algae and fungi develops.
Step 1 – Application
Apply WeberAlgenentferner generously to the facade surface and let it work. Clean the facade surface using a high-pressure cleaner with the addition of WeberFassadenrein – let dry. If necessary, apply WeberAlgenentferner again and let dry.
Step 2 – Application
Apply two coats of WeberTon additionally equipped with biocide in the desired color tone with a painter’s brush, brush, or paint roller.
Step 3 – Application
The correct painting consistency is achieved by adding clear water. Primer: paint WeberTon renotherm diluted approx. 15-20% with clear water. Top coat: paint WeberTon renotherm diluted approx. 5-10% with clear water.
Just ask the developer to show you such an older facade!
Best regards
