Keim Silan 100 is a solvent free, silane-based water repellent for use on all mineral substrates, particularly suitable for concrete, where carbonation resistance is required.
Concrete carbonation is caused by carbon dioxide in the environment reacting with the calcium hydroxide in the cement paste, causing the pH to drop to a point where reinforcing steel can start to erode. The speed of this process is determined by the quality of the concrete.
The features listed below give you a quick snapshot of what Keim Silan 100 offers:
Substrate Preparation
