TYROLIT Densifier 3 is a concrete densifier and surface hardener. It is used after the grinding steps (and before the polishing steps), in order to give the floor its final mechanical properties. Densifier 3 consists of mixed silicates which densify the mineral surfaces and have a dust-binding effect. The resistance of the floor to mechanical loads and abrasion is improved by hardening and densification. The resistance of the floor to water absorption is also increased.
