Two-component epoxy primer with fillers. May be coloured with Mapecolor Paste.

Where to use: 

Primer SN has been specifically formulated to carry out preliminary priming treatments on surfaces before applying epoxy and polyurethane resin systems from the Mapefloor range, self-levelling cementitious mortars from the Ultratop/Ultratop Living range and of Ultratop Loft, to protect and coat civil and industrial floors, terrazzo floors and cementitious substrates in general.
