Restoration Plaster System


When masonry is just slightly moist, often a restoration with KÖSTER Restoration Plasters is enough to dry the wall and stop damage from occurring. In this case, the old plaster has to be removed from the wall and the joints raked out. All loose particles have to be removed to provide a stable and absorptive, open-pored surface. Priming with KÖSTER Polysil TG 500 optimally prepares the masonry for the application of KÖSTER Restoration Plaster.

KÖSTER Polysil TG 500 hardens the substrate as well as reduces the mobility of salts. Masonry repairs are carried out with KÖSTER Repair Mortar Plus. Before the application of the main plaster coat, a plaster key made from the chosen KÖSTER Restoration Plaster mixed with KÖSTER SB-Bonding Emulsion is applied to provide a larger surface area and to ensure an optimal bond to the substrate.

KÖSTER Restoration Plaster allows the masonry to dry without damage. KÖSTER Restoration plasters are open to diffusion and are hydrophobic. Salts remaining in the wall are absorbed by the KÖSTER Restoration Plasters so the salt doesn’t effloresce to the surface and doesn’t cause damage to the plaster or paint.

KÖSTER Restoration Plasters are available in different varieties (grey, white, fast and light). KÖSTER Restoration Plaster 2 White is often used in older buildings without subsequent painting. KÖSTER Plaster Coat creates a very smooth surface and can be applied when desired to meet architectural needs. KÖSTER Restoration Plasters can only be painted over with breathable (open to vapour diffusion) paints such as KÖSTER Silicon Paint White or KÖSTER MF1.

System Components:
