STRiON:FORTIFY MAX
THE HIGHEST PERFORMING, EASIEST TO USE DENSIFIER ON THE MARKET. THE NEXT EVOLUTION OF THE STRION TECHNOLOGY.

Not only is it remarkably easy to apply, but it can be applied at temperatures as low as 25°F – and no rinsing is required, making it not only simple but also easy on the environment. It can be applied to freshly placed concrete and tilt-up construction slabs, and it can also be used on existing concrete surfaces and cementitious overlays as well.
