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拼花面積很大，縫(feng)(feng)隙(xi)較款時，可選用“手提切割機+0.2mm清縫(feng)(feng)片”進行清理。清縫(feng)(feng)深度(du)要(yao)(yao)達到3mm以上，越(yue)深整體(ti)結構強度(du)越(yue)高。清縫(feng)(feng)時，一定要(yao)(yao)保(bao)持石材的原貌(mao)，不(bu)(bu)要(yao)(yao)拓寬縫(feng)(feng)隙(xi)。縫(feng)(feng)隙(xi)盡頭處，不(bu)(bu)要(yao)(yao)切過了。不(bu)(bu)要(yao)(yao)切串縫(feng)(feng)——就是不(bu)(bu)要(yao)(yao)沿著(zhu)一條縫(feng)(feng)清理時，不(bu)(bu)小心歪出去。
