the trick is to keep water out
PROTECTOSIL® WATER REPELLENTS
The penetration of moisture is the main cause for construction damage
Moisture is the root cause of almost all mechanisms that damage mineral building materials. Therefore, Protectosil® water repellents offer deep protection against the ingress of water and dissolved contaminants into the building structure, thus preventing damages. In addition to a clearly extended service life and a permanent representative look of buildings, Evonik’s professional building protection systems help reduce maintenance, repair and energy costs.
Protectosil® provides deep hydrophobing for permanent protection.
The porous nature of many substrates allows water and therein dissolved contaminants to penetrate via capillary suction into the pores. This may cause various problems such as corrosion of reinforcing steel, salt burst, or freezethaw damage. There is no doubt that by preventing water ingress into a structure, damage is drastically reduced.
Protectosil® water repellent products penetrate deep into the substrate and create the best long-term protection for a building.
Very alkaline substrates like concrete can be protected for a long period of time. Protectosil® water repellents meet the requirements of EN 1504-2 and have been tested according to NHWA #244.

Protectosil® offers deep protection that cannot be destroyed by UV exposure or abrasive load.
The protective action of Protectosil® lasts significantly longer than that of a coating.
Protectosil® water repellent products do not change the appearance of the substrate.
After treatment with Protectosil® the surface can be treated further, for example with a colored paint.
