FIELD: chemistry.
SUBSTANCE: seam composition for the seams of adjacent wall slabs includes nanocrystalline cellulose, water, filler, binder and thickener, the content of nanocrystalline cellulose sufficient to improve the resistance to cracking of the suture composition upon drying, the diameter of the nanocrystalline cellulose is less than 60 nm, the content of nanocrystalline cellulose is from 0.05 to 0.15 wt %, based on the total weight of the composition, and the thickener content is from 0.3 to 0.5 wt %, based on the total weight of the composition. The invention is developed in subclaims.
EFFECT: elimination of the formation of cracks in different thicknesses of the material.
