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(shi)(shi)，可選用“手(shou)提(ti)切割機+0.2mm清(qing)(qing)縫(feng)(feng)片”進行清(qing)(qing)理。清(qing)(qing)縫(feng)(feng)深度要(yao)達到3mm以上(shang)，越深整體(ti)結構強度越高。清(qing)(qing)縫(feng)(feng)時(shi)(shi)，一定要(yao)保持石材的原貌，不要(yao)拓寬縫(feng)(feng)隙(xi)。縫(feng)(feng)隙(xi)盡(jin)頭處，不要(yao)切過了(le)。不要(yao)切串縫(feng)(feng)——就是(shi)不要(yao)沿著一條(tiao)縫(feng)(feng)清(qing)(qing)理時(shi)(shi)，不小心歪出去。
