Waterborne, dispersion primer with Nano Priming Technology. The application of this exceptional solution consist in use of two dispersions with different particle sizes, including one of nanometric dimensions. Due to this composition the primer excellently penetrates, fills and anchors in the pores of the substrate. It reinforces the substrate structure, limits and smoothes out absorbability, unifies in respect of colours, improves adhesiveness of facade paint and insulates finishing coat against the impact of substrate factors. Reduces to a considerable degree the use of facade paint.
