水刷石是一项传统的外装工艺,传统作法多采用单一的中八厘石碴或小八厘石碴与水泥相掺调制石子浆。实际操作中感到,用中八厘石碴抹水刷石,和易性差,抹、压比较费力,石层比较厚,一般不低于12毫米,表面平整不易掌握,用料较多,表面显露石碴颗粒大,孔隙也较大;外观效果远看比较好,近看石碴显得不够紧密,施 Water brush stone is a traditional exterior decoration process. The traditional practice is to use a single medium of 8 PCT or small PCT. In practice, it is felt that brushing stones with water in the middle of the penalties of Shiji is not easy to use, and it is difficult to wipe and press. The stone layer is relatively thick, generally not less than 12 mm, and the surface is smooth and difficult to grasp. The material is used more often and the surface is exposed. Dendrobium has large particles and large pores; the appearance effect is far better viewed, and the stone worms are not close enough.
