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拼花面積很(hen)大，縫(feng)隙較款時，可選(xuan)用“手提切割(ge)機(ji)+0.2mm清(qing)縫(feng)片”進行清(qing)理。清(qing)縫(feng)深度(du)(du)要(yao)(yao)達到3mm以上，越深整體結構(gou)強(qiang)度(du)(du)越高(gao)。清(qing)縫(feng)時，一定(ding)要(yao)(yao)保持石材的(de)原貌(mao)，不(bu)要(yao)(yao)拓寬縫(feng)隙。縫(feng)隙盡頭處，不(bu)要(yao)(yao)切過了。不(bu)要(yao)(yao)切串縫(feng)——就是(shi)不(bu)要(yao)(yao)沿著一條縫(feng)清(qing)理時，不(bu)小心歪出去(qu)。
