Epoxy floor paint is a kind of high strength, wear-resistant and beautiful floor. It has many advantages, such as seamless, solid texture, good resistance, anti-corrosion, dust-proof, easy maintenance and low maintenance cost. It can be used to design a variety of epoxy floor paint construction process solutions according to different requirements. However, there are also consumers will encounter poor hardness after the construction of epoxy floor paint, what is the reason?环氧地坪漆硬度不好的原因大致有三点：
There are three reasons for the poor hardness of epoxy floor paint:
1. The quality of the selected epoxy floor paint materials is problematic. Guanglei floor paint manufacturers remind us that we must not greedily seek cheap floor paint materials without quality assurance.
2. The proportion of curing agent and diluent is problematic. For example, when the proportion of curing agent decreases, the hardness of floor paint will be low. In the use of floor paint materials, materials must be formulated strictly in accordance with the proportions.
3. Construction temperature, if the weather is too cold, the floor paint is in a solidified state, the main paint of curing agent and diluent can not be well mixed, and the hardness of natural floor paint will also be low. 测试环氧地坪漆漆膜硬度的方法：
Method for testing film hardness of epoxy floor paint:
To test the film hardness of epoxy floor paint, a set of Chinese advanced drawing pencils with 18 grades of 6B, 5B, 4B, 3B, 2B, B, HB, F, H, 1H, 2H, 3H, 4H, 5H, 6H, 7H, 8H and 9H are needed. From 6B to 9H, the hardness of pencil increases gradually.
A. Pencil processing. Cut off the pencil rod to expose the lead core 3 mm. The pencil is perpendicular to the sandpaper and rubs in a circle on the sandpaper to make the end face flat and the edge clear and sharp.
B. Push pressure. Starting from 6B, make pencil and epoxy floor paint 45 degrees, then press with appropriate force, with lead core continuously limited, push speed is 1cm/s, each hardness label should scrape 5 routes, each scrape a lead core to grind, to ensure that the lead core face is flat before each scrape, sharp edges.
