FIELD: construction. ^ SUBSTANCE: invention pertains to the protective medium from contamination of the surface of fibrolite slabs and to a fibrolite slab with the given medium. The protective medium, which forms a super-hydrophilic anti-splash film after being deposited on the surface of the fibrolite slab, consists of the following components with the given percentage mass ratios: 0.1-10 pyrogenic silica, 2-10% spirit, 0.01-0.25% surface active substance, and water constituting the remaining percentage. The fibrolite slab has a super-hydrophilic anti-splash film, obtained by depositing the given protective medium on its surface with subsequent drying. The fibrolite slab can be obtained through preliminary deposition of a coating compound on its surface with formation of a coating and deposition after 10-60 s of the protective medium on the given coating, under half-dry conditions, with subsequent drying during heating. ^ EFFECT: infusion of resistance to contamination to the surface of the fibrolite surface, which can be retained for a long period. ^ 3 cl, 2 tbl, 3 ex |
