环氧地坪项目施工时，底漆层的涂布是环氧地坪施工过程中最基础的一步。底漆层处于地坪基面与环氧地坪涂层之间，这样可以增强环氧地坪涂层与地面的附着力。那么，可能有人会问环氧地坪底漆的使用量究竟多少才算合适呢?其实，环氧地坪底漆的使用量是受多种因素影响的。

In the construction of epoxy floor project, primer coat is the most basic step in the construction of epoxy floor. The primer layer is located between the epoxy floor coating and the base surface of the floor, which can enhance the adhesion of the epoxy floor coating to the ground. Then, some people may ask how much is the use of epoxy floor primer appropriate? In fact, the use of epoxy floor primer is affected by a variety of factors.

1、地面强度

1. Ground strength

影响环氧地坪底漆使用量的最主要因素是地坪施工基面的粘结强度，进而影响整体的强度。施工环氧地坪的时候一般要求混凝土地面的强度大于C25，较好的地面中底漆用量一般在0.05~0.2kg/m2，若地面强度过低，地面疏松，易起砂，则环氧地坪底漆的使用量则会根据实际环境跟情况而改变用量。

The most important factor affecting the use of epoxy floor primer is the bond strength of the floor construction base, and then affects the overall strength. In the construction of epoxy floor, the strength of concrete floor is generally greater than C25, and the amount of primer used in the better floor is generally 0.05-0.2 kg/m2. If the ground strength is too low, the ground is loose and easy to sand, the amount of primer used in the epoxy floor will be changed according to the actual environment and the situation.

此外，如果地坪施工基面强度低，但又没有涂布适当适量的环氧地坪底漆来增加地坪基面粘结强度，则环氧地坪质量较差。如果地坪上有叉车等重物时，环氧地坪就可能会连同环氧地坪基面一起被压陷拉裂。

In addition, the quality of epoxy floors is poor if the base strength of floor construction is low, but the epoxy floors are not coated with proper amount of epoxy primer to increase the adhesion strength of the base. If there is a forklift on the floor, the epoxy floor may be collapsed and cracked together with the epoxy floor.

因此，在环氧地坪施工时，一定要保证底漆的涂布量适量。如果地面整体强度过低，则可根据承重及强度要求选用环氧涂层，或者有条件的可重新进行地面改造。

Therefore, in the construction of epoxy floor, we must ensure that the amount of primer coating is moderate. If the overall strength of the ground is too low, epoxy coating can be selected according to the load-bearing and strength requirements, or the ground can be reconstructed conditionally.

2、地面磨损程度

2. Ground wear degree

新旧地面，当然磨损程度不一样，旧地面根据使用时间长短及各种承载使用程度的不同，其地面的损坏程度也跟着不一样，有时候地面会出现大面积的坑坑洼洼和裂缝等问题，因此在施工环氧底涂之前一定要对进行地面的修补，对裂缝及坑洞修复及地面平整度的控制都相当的有必要。在面对一个较新地面环境，其地面强度及平整度较好时，一般的用量控制在0.05~0.2kg/m2范围;而面对老旧地面，地坪专业技术人员会结合实际情况为您的地坪控制用料，考虑客户考虑不到的。

New and old ground, of course, the degree of wear and tear is different, the old ground according to the length of use and the different degree of use of various loads, the degree of damage to the ground is also different, sometimes the ground will appear in a large area of pits and cracks and other issues, so in the construction of epoxy primer must be before the ground repair It is necessary to control cracks and holes and control the surface evenness. In the face of a relatively new ground environment, its ground strength and smoothness is better, the general dosage is controlled in the range of 0.05-0.2 kg/m2; and in the face of the old ground, the floor professional and technical personnel will take into account the actual situation for your floor control materials, considering customers can not consider.
