Neodur Varnish PR is a suitable coating for sealing on porous surfaces and concrete floors to prevent dust formation. It is an ideal primer for cement based surfaces, such as pressed cement mortars, which are to be covered with polyurethane varnishes Neodur varnish and Neodur varnish W.
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
