清理縫隙若縫隙<0.2mm對于縫隙極小的石材拼花，清縫環節，基本上不允許使用機械進行操作。如果采用手提切割機和清縫片等設備，一方面易造成縫隙切割放大;另一方面會產生很高的熱量，導致崩邊等問題，破壞整體裝飾效果。手工清理。選用精工刀片，很薄的那種。有些地方，甚至需要用到更薄的剃須刀片來進行清理。清縫時，速度要慢，避免拼花細節處的破壞。清縫完成后，用大功率的吸塵器，將縫隙處的灰塵吸走。若縫隙>0.2mm拼(pin)花面積很大(da)，縫(feng)隙較款時(shi)，可(ke)選用“手提切割機(ji)+0.2mm清縫(feng)片”進行清理(li)。清縫(feng)深度(du)要達到3mm以(yi)上，越(yue)(yue)深整體(ti)結(jie)構強度(du)越(yue)(yue)高(gao)。清縫(feng)時(shi)，一(yi)定要保持石(shi)材的原貌(mao)，不(bu)(bu)要拓寬縫(feng)隙。縫(feng)隙盡頭處，不(bu)(bu)要切過(guo)了(le)。不(bu)(bu)要切串(chuan)縫(feng)——就是不(bu)(bu)要沿著一(yi)條縫(feng)清理(li)時(shi)，不(bu)(bu)小(xiao)心歪出去。
