4mm厚的GPU 彩砂自流平系统可以充分耐60℃的温度；
6mm厚的GPU 彩砂自流平系统可以充分耐70℃高温，且可以进行轻度蒸汽清洗；
9mm厚的GPU 彩砂自流平可以充分耐120℃高温且完全可以用蒸汽清洗，因此需要设计非常优秀的基层系统。
4 mm thick GPU colour sand self-leveling system can make full 60 ℃ temperature resistance;
6 mm thick GPU colour sand self-leveling system can be fully resistant to high temperature of 70 ℃, and can be a modest steam cleaning;
9 mm thick of GPU colour sand self-leveling can fully 120 ℃ high temperature resistant and can steam cleaning, so need to design very good system at the grass-roots level.
