Siloxane penetrates surfaces, forming a layer with water-repellent properties that also provides long-term protection against potential damage from UV radiation and salts. Siloxane is applied to surfaces twice using the wet-on-wet method. Before post-processing the surface with solvent-based substances, the siloxane must be allowed to dry for at least 48 hours.
Summary of properties
- Does not stain surfaces or cause colour changes.
- Suitable for use on all cement-based and brick surfaces.
- Single-component – easy to use.
- Treated surfaces must be dry on the outside.
- Water-repellent properties help prevent cold damage.
- Prevents access and deposition of chlorides and other corrosive salts to and on the treated surface.
- Forms a breathable layer that allows moisture to evaporate from the treated surface to ensure that the element is able to dry.
- Reduces penetration of moisture into the treated surface.
- Prevents the formation of mould.
- Protection of façades against damage caused by chlorides.
- Protection of bridges (VTT, SILKO research report).
- Protection of masonry and brick surfaces against the deposition of dirt and salts.
- Protection of exposed aggregate concrete against ingress of moisture.
Siloxane is not suitable for waterproofing surfaces, nor protecting them against gases or carbonisation. The extent of absorption depends on the structure of the treated surface and the presence of ice or water. Siloxane is not very effective in plaster.
