我们在外檐装修施工中,在没有白水泥的情况下,采用水泥砂浆抹灰面层压白灰膏、再刷白灰浆的工艺,取得了良好效果。这种施工工艺的操作,是在抹上面层水泥砂浆后,先不起靠尺,不上干水泥,随即在砂浆表面压上薄薄一层(约0.5～1.0毫米厚)白灰膏。这样,既不降低砂浆强度,同时使灰膏借水泥强度附着牢固并保持白色。若水泥面初凝后出现花脸现象,可采用生化石灰块加食盐过细罗灰浆(有条件可用大
In the construction of exterior decoration, in the absence of white cement, the use of cement mortar plaster surface laminated white plaster, and then brush the white mortar technology, and achieved good results.
