Abstract
An improvement in the treatment of anodic oxidized aluminum surfaces with subsequent sealing with hot water or steam. The improvement comprises either an intermediate treatment or a combined treatment with the sealing of the aluminum surfaces at temperatures of from 150 DEG C to 100 DEG C with a solution of dextrin. The treatment prevents the formation of sealing films without impairing the anodic oxide coating or the quality of the after-sealing.
