Durable renovation of damaged organic overlay renders with mineral renders within ETICS

In Germany alone, a facade surface of several million square meters is in need of renovation. This also includes facade surfaces that have been provided with an external thermal insulation composite system. Systems with insulation thicknesses of 4 - 8 cm and coatings of synthetic resin renders are particularly prone to damage. In combination with different processing techniques, the materials used are the typical cause of the most frequent damage patterns.
