Waterproof paper SAIT for manual wet sanding, is used for getting high quality surface. Elastic, tear-resistant base paper with anti-slip structure does not curl in water and does not require a long soak. Binder of synthetic resin protects the paper from the eruption of abrasive grain. The applied silicon carbide grain, evenly poured onto the paper substrate, ensures extremely uniform grinding, creating an ideal surface. Paper with grain sizes from Р220 to Р7000 is used for polishing and elimination of defects of any complexity.
