DuraSil P is a single component, water-based surface hardener based on potassium silicates. These silicates react with the calcium hydroxide within the concrete matrix to harden the concrete surface making the concrete surface dust free and easier to clean.

An advantage of potassium silicates over sodium silicates is a reduced tendency for the formation of white deposits on the surface from densifier pooling.
