FIELD: manufacture of facing brick and ceramic blocks. SUBSTANCE: proposed method includes forming green brick, burning and soaking by dipping in 0.2-03-% aqueous solution of potassium methyl siliconate at mass content of silicon of 0.04-0.06%. Soaking is performed by wetting the brick and ceramic blocks for 4 to 8 minutes. Proposed method ensures absorption of water by mass of 6-7% at adhesive strength of mortar of 0.6 MPa. EFFECT: enhanced efficiency. 1 tbl
