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(hua)面積很(hen)大，縫(feng)隙(xi)較款時(shi)，可選用(yong)“手提切割機(ji)+0.2mm清縫(feng)片(pian)”進行清理(li)(li)。清縫(feng)深度要(yao)達(da)到(dao)3mm以(yi)上，越(yue)深整體結(jie)構(gou)強度越(yue)高。清縫(feng)時(shi)，一(yi)定要(yao)保持石(shi)材的原貌，不(bu)(bu)要(yao)拓寬(kuan)縫(feng)隙(xi)。縫(feng)隙(xi)盡頭處，不(bu)(bu)要(yao)切過了(le)。不(bu)(bu)要(yao)切串縫(feng)——就(jiu)是不(bu)(bu)要(yao)沿著一(yi)條縫(feng)清理(li)(li)時(shi)，不(bu)(bu)小心歪出去。
