KEIM Silex®-OH-100 (Consolidant) is a colourless and solvent-free, silicate-based consolidant, further based on silicic acid ester (OH means "without water repellent).
Thanks to its excellent fluidity, KEIM Silex-OH-100 penetrates deep into the pores of building materials. The silicate reacts chemically with the moisture naturally present in the building material and atmospheric humidity to form silica gel and alcohol.
This reaction generally takes 4 weeks. After this period, only the silica gel remains in the building material, the alcohol has evaporated. Deposition of the mineral gel effectively consolidates the previously crumbly building material without impairing water vapour permeability.
