Product based on silicic acid ethyl ester. After the capillary system is used, the building material absorbs this product, transporting it to deeper zones. With the aid of a neutral catalyst, the silicic acid ethyl ester reacts with the atmospheric humidity, suitably with the water absorbed by the capillary walls. The product has no hydrophobic additives, such as silicon-methane and silicone resins. During the reaction, a droplet effect may appear on the surface made, which is not related to the hydrophobic effect itself.

Features

• dries without stickiness, dust does not stick
• there are no byproducts that adversely affect building materials
• small molecules of the product allow for optimal penetration
• the newly formed binder is a mineral and therefore has an affinity with building materials
• the newly formed binder is acid-resistant and therefore resistant to rainfall
• it is a one-component system and therefore easy to apply
• the pores are not completely sealed, so the improved building material retains water vapor permeability

Application

The product is mainly used for restoration of stucco, natural stones or frescoes damaged by weather conditions. In addition, it can be used to strengthen other materials, such as terracotta or brick. It is suitable for all mineral and absorbent building materials which, after saturation with them, regain their original porosity and hardness.
