Properties/Benefits
Water primer, with high hardness and good resistance to water and chemicals.
It is acrylic-aliphaatic polyurethane and does not turn yellow.
It is applied as a primer on the pressed cement mortar and maintains its natural appearance, without darkening their hue or creating effects of wet surface after the passage of finished varnishes
