High-quality render systems provide lasting protection

From June to November 2024, interior rendering work was carried out at St. Paulus Church in Hamburg. The renovation was urgently needed, as the old render had suffered severe damage. Cracks, moisture penetration and visual defects significantly affected both the structural integrity and the appearance of the church. Due to the heterogeneous composition of the masonry, which partially consists of mixed masonry, a specialised approach was required. The complex geometry of various structural elements – including the chancel apse, arches, and pillars – also demanded exceptional craftsmanship from the applicators.

MC cement-free plasters provide long-lasting protection and a high quality finish

A specially tailored system was used for the renovation, offering a durable and sustainable solution for the damaged building structure. To ensure long-lasting adhesion of MC’s cement-free render system, stainless steel ribbed expanded metal was first installed as a support in the masonry. The next step involved applying the bonding coat Exzellent STP 540, which ensured optimal adhesion to the mixed masonry. This was followed by the levelling render Elegant MRP, which evened out irregularities and created a uniform base for the subsequent render layers. The final render layer also consisted of Elegant MRP, which, thanks to its moisture-regulating properties, provided a resistant and stable surface. The finishing coat was chosen from the same product line to achieve a high-quality and aesthetically pleasing final appearance.
