DUROSTICK DS-255 - QUARTZ SEALER PRIMER

Ready-to-use primer of a special acrylic base, without solvents, with quartz  aggregates, enriched with improving additives. It stands out for its strong  adhesion even on very smooth surfaces. It has excellent resistance to alkalis  while at the same time acting as a barrier to incoming moisture, protecting the  building from unwanted damage. It does not prevent the transpiration of  buildings. It is essential on surfaces where traditional plaster is difficult to  adhere to, such as extruded or expanded polystyrene placed for insulation on  building facades. Also ideal as a primer before the application of D-6 cement  mortar on the COOL ROOF THERMAL SEALING SYSTEM, as well as before the  installation of the pressed cement mortars DS-250, DS-254 IRON on tiles, marble  or mosaic and DS-252 FLEX on floors of marine plywood or thoroughly cleaned  sheet metal. In addition, suitable for substrates with underfloor heating.
