Remmers Funcosil FC is especially used for hydrophobizing impregnation of porous, mineral building materials. Funcosil FC is a special product for hydrophobizing impregnation of brick, clinker, sand-lime brick, silicate types of natural stone, e.g. OBERNKIRCHENER SANDSTEIN® and mineral render.
Features & Benefits
Early rain tight Remmers Funcosil FC is excellently suited for hydrophobizing mineral building materials. As opposed to conventional liquid products, Funcosil FC can be applied in just one working operation. Depending on porosity, the active ingredient penetrates into the substrate where it reacts and becomes a polysiloxane. The initially white layer disappears completely after approx. 10 to 20 minutes.
Funcosil FC has been designed so that the active ingredient penetrates as deeply as possible into the facade which provides optimal protection against the absorption of water and pollutants and therefore also damage caused by frost/de-icing salt. Funcosil FC’s water repelling effect takes longer to develop and is improved by rain.

![]() | Question:
Hi. I have a weather facing wall that is often hit by driving rain. It is made of brick which is currently painted. Can I use Remmers Funcosil FC on top of the current paint (making sure it is in a good state of course) before applying a new top coat of paint. Thanks p.s. if you have any suggestions for a better solution I would be happy to hear them. |
Answer:
Remmers Funcosil FC is a penetrating/impregnating solution that needs to soak into a bare, porous surface so cannot be applied over existing painted surfaces. If you are trying to provide more waterproofing protection to your exterior wall you would be better looking at re-painting the wall with something like Rust-Oleum Mathys Murfill Waterproofing Coating | |
