Primer and Primer H are two epoxy-based products that come in the form of two factory pre-dosed components: a resin part and a hardener part.
In order to ensure good adhesion between the substrate and the tile or resin flooring, the use of a bonding primer is essential. To further strengthen the bond, sand the primer with HN0.6-1.6 sand.
The most commonly used primer is FB67. It can be applied directly on dry, previously prepared concrete. However, in case the conditions on site do not allow to obtain a dry concrete, it is possible to apply a special primer for wet concrete substrate, the H primer.
