SKU: N/A Category:


  • Ready-to-use primer of special acrylic base, without solvents, with quartz aggregates, enriched with improving additives. It is distinguished for its strong adhesion even on very smooth surfaces. It has excellent resistance to alkalis while at the same time acting as a barrier of incoming moisture, protecting the building from unwanted damage. It does not prevent the perspiration of buildings.
    It is necessary on surfaces where traditional cast plaster is difficult to adhere to, such as extruded or expanded polystyrene that is placed for insulation on the facades of buildings. “Prevents” possible detachment of plasters on interior and exterior surfaces from seismic vibrations as well as shrinkage of insulating materials.
