PLASTER MATERIAL FOR THICK COATING

摘要

An improved thick set plastering material is prepared by adding to a conventional plastering material a synthetic high molecular (organic) admixture and a mixed aggregate wherein the ratio of inorganic binder to the mixed aggregate is 1:1 to 1:4 by volume and wherein the mixed aggregate includes slag and an organic or inorganic lightweight spheroidal substance. Such a plastering material can be laid on with a coat thickness of 5 mm to 20 mm in a single trowelling as well as being possibly applied in successive coats or layers as fresh mortar.
