PSB Deep Penetrating Primer 10l Wall primer for absorbent and porous surfaces, indoors and outdoors. Added to adhesive mortars, it protects them against cracking. Coverage: 0.05-0.2 l/m2; Advantages: Deeply penetrating – penetrates the substrate structure, reaching its deeper layers, which effectively strengthens the material from the inside and stabilizes its structure. Universal – suitable for indoor and outdoor use, on absorbent and porous surfaces. Evens out and reduces the absorbency of the substrate – ensures even absorption of paints, plasters, finish coats and adhesives. Strengthens the structure of the substrate – increases its load-bearing capacity and durability, preventing dusting and crumbling. Increases the adhesion of subsequent layers – guarantees better binding of paints, mortars and plasters. Makes wallpaper removal easier during renovation – speeds up and facilitates renovation work. Increases flexibility and scratch resistance – extends the durability of finished surfaces. Economical – yield 0.05–0.2 l/m² ensures low consumption over large surfaces. Application: Priming of absorbent and porous substrates (aerated concrete, concrete, cement boards, gypsum boards, plasterboards, gypsum, cement and cement-lime plasters), primer for paints, plasters, wallpapers, screeds, leveling and self-leveling floors, putties, adhesives, ceramic tiles, acrylic and mineral plasters, protective coating for screeds.
