Consolidant based on ethyl silicate and additives in an inert solvent mixture.

The special solvents allow optimal absorption of the active ingredient through the capillaries of the stone material until it reaches the healthy core of the stone. Here, following a chemical reaction with atmospheric humidity, it transforms into silica gel which then acts as a binder for the loose material without producing any saline by-products. BIO CPA does not alter the breathability of the substrate or reduce its water vapour permeability, does not change the colour of the treated materials and is highly resistant to UV rays.
