Sika releases a reactive siloxane modified acrylic concrete stain.

Sika Corporation is proud to release SikaColor®-400 Opaque, an reactive acrylic solid color concrete stain that provides excellent physical properties intended to stain concrete or cement-based material. SikaColor®-400 Opaque has the capabilities to adhere to the concrete resulting in no pealing of the coating.
