1、排除水分
1, out of the water
施工塑胶跑道混凝土含水率应小于5%，应排除水分后方可进行涂装。排除水分的方法有以下两种：可以加强空气循环，加速空气流动带走水分可以促进混凝土中水分进一步挥发，或者用脱水减湿剂、除湿器或引进室外空气方法除去空气中的水汽。
Plastic runway construction concrete moisture content should be less than 5%, should be excluded from moisture before painting. The following two ways out of the water: can enhance air circulation, accelerate the air flow away moisture can promote concrete water further volatile, or dehydration dehumidifying agent, or the introduction of outdoor air dehumidifier air moisture removing method.
2、除碱
2, in addition to alkali
对于PH值大于8的地面，一般用酸洗法：用质量分数为10~15%的盐酸清洗混凝土表面待反应后，用清水冲洗并配合毛刷刷洗。
The pH value of more than 8 of the ground, the pickling method generally used: the mass fraction of 10~15% hydrochloric acid cleaning the surface of the concrete to be after reaction, rinse with water and with the scrub brush.
3、不平
3, uneven
平整度较差或过于光滑宜采用机械方法：用喷砂或电磨机清除表面突出物和松动颗粒，并破坏毛细孔、增加附着面积，以吸尘器吸除砂粒、杂质、灰尘。对于有较多凹陷应用塑胶与石英砂或细胶粒配成砂浆或腻子填平修补。
Smoothness is poor or too smooth and appropriate uses mechanical methods: sandblasting or electric grinder to remove surface protrusions and loose particles, and destroy Mao Xikong, increased attachment area, with cleaner suction sand, impurity and dust. For application of plastic and quartz sand or fine particles mixed into the mortar or putty to fill the patch more depression.
