Remmers Funcosil SL is effective over a wide range, especially as an impregnation agent for natural stone and lime based natural stone in particular. Reactive, oligomer siloxane solution for water repelling impregnation of mineral building materials. The product was especially developed as a water repelling treatment for natural stone and limestone in particular (e.g. shell limestone).

Because of its low molecular structure in the packaged state, Remmers Funcosil SL has very good penetration capacity and reacts chemically in the building material in the presence of humidity to become a water repelling, UV-lightfast and weather resistant material - polysiloxane.

After application, the active ingredients are deposited on the walls of capillaries and pores as a macro-molecular layer that does not essentially influence water vapour diffusion capacity. Uneven absorbency of the substrate can lead to differences in the amount of impregnation agent that is absorbed which in turn may lead to differences in colour.

Remmers Funcosil SL reduces the absorption of water and pollutants which are found in the form of water soluble acidic atmospheric gasses (SO2, NOx). Infestation of natural stone surfaces with micro-organisms is reduced by the impregnation and frost/de-icing salt resistance is improved. Energy loss is also reduced because the building material is protected against moisture penetration. Building material surfaces impregnated with Remmers Funcosil SL also have much less tendency to soil.
