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拼花面(mian)積很大，縫隙(xi)較款時，可選用“手(shou)提切割機+0.2mm清(qing)縫片”進行清(qing)理(li)(li)。清(qing)縫深度要(yao)達(da)到3mm以上，越深整體結構強(qiang)度越高。清(qing)縫時，一定要(yao)保持石材的原貌，不(bu)(bu)(bu)要(yao)拓寬縫隙(xi)。縫隙(xi)盡頭處，不(bu)(bu)(bu)要(yao)切過(guo)了。不(bu)(bu)(bu)要(yao)切串縫——就是不(bu)(bu)(bu)要(yao)沿著一條縫清(qing)理(li)(li)時，不(bu)(bu)(bu)小心歪出去。
