For the repair of masonry damaged by moisture and salt, particularly following the installation of a horizontal barrier, the application of KÖSTER Thermal Restoration Plaster is highly recommended. This is effective for all levels of moisture and salt content within the masonry. Additionally, it enhances the insulation value of the masonry and serves as a preventative measure against mold growth. The use of approx. 50% high-quality renewable raw materials make this plaster ecologically sustainable in several aspects.
Before commencing repair work, loose material and salt efflorescence must be mechanically removed. The substrate should then be primed with KÖSTER Polysil TG 500, which hardens the substrate and reduces the mobility of salts. Masonry repairs are carried out with KÖSTER Repair Mortar. Before the application of the plaster coat, KÖSTER Restoration Plaster Key is applied to increase the surface area and to ensure an optimal bond to the substrate.
KÖSTER Thermal Restoration Plaster is applied in a layer thickness of up to 3 cm. Immediately afterward, KÖSTER Glass Fiber Mesh is embedded into the surface. After a minimum of 60 minutes, the second layer of KÖSTER Thermal Restoration Plaster is applied in a layer thickness of max. 2 cm. For surface smoothing in interior areas, KÖSTER Hydrosilicate Adhesive SK can be applied in a layer thickness of up to 2 mm. KÖSTER Thermal Restoration Plaster can only be painted over with breathable (open to vapor diffusion) paint such as KÖSTER Renovation Paint White. In case of deviating layer build-up, please contact our Technical Service.
