SILICON IMPREGNATION REPOL S 4
- open to vapour diffusion
Ready-to-use, single-component, transparent, solvent-based facade impregnation agent with very good alkali resistance based on an oligomeric siloxane. Forms a hydrophobic surface, where salt efflorescence, moss growth and the formation of mould are reduced and the cleaning capability of the surface is improved. Tested surface protection system as per EN 1504-2. Repol Silicon Impregnation S4 reduces the moisture absorbency of the exterior wall and thus lowers its thermal conductivity – this has a positive effect on the heating costs.
0.2 - 0.5 l/m² per coat depending on the absorbency of the substrate
