    2、湿度,指的是空气中水分的含量,一般用百分比来表示。如果有结露现象出现,说明空气的相对湿度达到百分之百。根据环氧地坪漆施工要求规定,当空气相对湿度高于85%时,是不能进行环氧地坪漆施工的,因为容易出现泛白、裂纹等弊病。(湿固化型聚氨酯涂料除外)。湿度不仅影响环氧地坪漆的施工,更是会影响地坪漆固化,湿度指数在过大的情况下才影响地坪涂装,它的影响往往大于人们的想象。湿度过高,会引起涂装表面结露,凝结的水会对固化剂造成破坏引起涂膜发白、失光、发黏、回黏等现象,大大降低表面装饰效果,严重时造成返工。特别无溶剂面漆,表干时间一般较长,在涂漆后马上下雨或在冬春季的傍晚涂漆都是有危险的。但有时因为业主要求工期,理想的天气条件不易出现,这时就需采取措施改善涂装小环境了,如开启空调加温和抽湿。
