FIELD: process engineering.
SUBSTANCE: invention relates to production of boards or tiles for application to floors or walls both indoors and outdoors. Proposed method comprises stages described below. Board or tile with visible surface is fitted in place At least thin support board or support tile with thermal expansion factor higher than that of said first board or plate is fitted in place. Note also said thin support board or plate features good viscosity and crack resistance. Said board or tile is heated for gluing to said thin board or tile or visa versa with the help of suitable glue. Thus, assembly is made for cooling to ambient temperature to make thin bearing board or tile excites, owing to excellent heat expansion (contraction) factor, in board or plate glued thereto, the state of contraction starting from bottom surface of board or tile opposite aforesaid visible surface.
EFFECT: perfected method.
