It is known to all who have done epoxy floor paint that the construction technology of epoxy floor paint is mainly divided into basic ground grinding treatment, primer construction, middle mortar layer construction, middle putty layer construction and top paint construction. Among them, the primer layer is directly in contact with the base floor, and its main function is to enhance the adhesion between the epoxy floor paint and the base floor and prevent the epoxy floor paint from peeling. Therefore, the quality of the base floor directly determines the amount of epoxy primer.
What is the amount of epoxy primer?
Ground strength is the key factor affecting the amount of epoxy floor primer. Generally speaking, we all require that the strength of concrete floor is greater than C25. If the ground is in good condition, the amount of primer per square meter is generally between 0.1 kg and 0.15 kg. But if the ground conditions are not good, such as sanding and loosening, then the specific dosage should be adjusted according to local conditions, according to the actual situation of the ground.
If the construction of epoxy floor paint is not in good condition and the amount of primer is not enough, the adhesion of epoxy floor paint after construction will be insufficient, and the quality problems of peeling and coating peeling will easily occur in the later use process
Therefore, when many customers call to ask the floor paint quotation, they are often impatient. Do they think that the price is not very simple? Why should we ask about the ground strength of the construction? In fact, it is closely related to the amount of primer we use.
Secondly, the situation of the ground also includes the degree of ground wear, which is also related to the amount of primer. If the ground is worn seriously, when pits, holes and cracks occur, it is better to repair them first and build a smooth ground, which is very helpful for us to control the amount of primer and the construction of epoxy floor behind.
High strength and smooth ground can save the amount of primer, so in order to accurately control the amount of primer, we need to invite professional floor construction team to the site to judge the situation of the ground, rather than blindly use according to the feeling, the amount of primer on different ground is not the same. Only when we accurately judge the situation on the ground can we remedy the problems and prescribe appropriate remedies. Generally speaking, the amount of floor primer is adjusted according to the actual situation of our ground. If it is not decided according to the actual situation, the epoxy floor coating will fall off and collapse afterwards. This primer also plays a connecting role and is very important for our whole floor project.
