Abstract

Apparatus for impregnating a porous article comprising a first support (16) for the article, a first cover (10) arranged to seal against the support to form an impregnation chamber, means for applying reduced pressure to the upper part of the first cover, means (4) for raising and lowering the first cover, passage means in the support for supplying impregnant to the impregnation chamber and removing it therefrom, a second support (15) adjacent the first support, conveyor means for moving the article from the first support to the second support, a second cover (11) arranged to cooperate with the second support to form a second treatment chamber, means (5) for raising and lowering the second cover, and means for treating the article with fluid in the second treatment chamber to effect washing of the article and/or curing of the impregnant in the pores of the article. Preferably the apparatus includes a third support (16) to form a third treatment chamber and means (6) for raising and lowering the third cover (12), the conveyor means being arranged to move the article consecutively from the first support to the second support and then form the-from the second support to the third support, and the second chamber being a washing chamber and the third chamber being a curing chamber. The invention also provides a method of impregnating porous articles in which excess impregnant is removed by centrifugal force and/or gas blast and in which curing of impregnant in the pores is effected by gas at a temperature in the range 60-130`C.
