Abstract: The use of new homogeneous highly water-repellent mortars has favored the design of new render and plaster systems, compatible with most of the surfaces on which they are used (lime, gypsum, cement, stone, brick...), in restoration and new construction. The non-salt transporting designed system with very high vapor transmission is applicable in the case of surfaces having a high moisture and salt content according to the case studies in the EU COMPASS Project.
This system is based on the application of two layers of mortar, both homogenously treated to be made water-repellent and colored in bulk (render/plaster-set) with high performance under the harshest of conditions. Other previous treatments of consolidation and water-repellent may also optionally be applied.
This system has proven itself to be both useful and versatile in more than 300 historic buildings and new constructions completed in 2004 and 2005.
