Renovation | Former ladies' convent Wasungen

More sustainability

The former monastery building is located directly on the main road in Wasungen and is now a real eye-catcher again. The façade shows the various developments during the building period and invites you to look around and linger in the beautiful garden. When listed buildings are preserved, utilised and managed again, a major goal is achieved - especially with a view to future generations.

Natural stone & exposed timber framework

Built almost 500 years ago for impoverished noblewomen, the ladies' convent in Wasungen, Thuringia, is currently undergoing extensive façade renovation. In addition to repairing the façades and thus ensuring protection from the weather, the main task is to comply with the guidelines for the protection of historical monuments.

The time-honoured building now houses the tourist information office, town museum and archive as well as the Thuringian Carnival Museum. The ground floor was always designed as a natural stone building, but has suffered extensive damage over the years due to weathering. As part of the refurbishment, the exposed timber framework had to be replastered, the badly damaged natural stone replaced and areas exposed to moisture and salt also plastered. The character of the building had to be preserved at all costs.

Rendering with a system

The different areas of the façade were renovated in different ways. The severely damaged natural stone masonry was completely repaired with a mineral plaster system: natural stone that had been heavily damaged by salt and frost was replaced, joints were removed in various areas, the substrate was cleaned and provided with a spray coating that did not cover the entire surface. Due to moisture and salt contamination up to a height of two metres, a restoration render system in accordance with WTA guidelines was used for the entire façade - with maxit san primer as a base coat and maxit san white as a finishing coat. The surface texture was adapted to the requirements of the building period.

In addition to the façade, a great deal of attention was paid to the exposed timber framing. It is important to render the timber framing in these parts to protect it from water damage. The timber framing was repaired and the existing rendering was retained. Natural stone was re-mortared and the base render was finished with maxit ip 390. In the end, the surfaces - both existing and newly plastered - were coated with maxit ip 316 fine lime plaster. Colour adjustments and design were carried out with silicate paints.
