1.

ooze color bleeding problem is refers to in a film on the lacquer of another kind of color coated, the bottom part of the infiltration into the surface coating and makes the phenomenon of coating color on the surface. Main causes of bleeding is: 1 primer, 2 primers and paint color, 3 no color material is contained in the bottom of the substrate or coating, 4 primer containing organic pigments.

2, paint a flower problem refers to the coating on the surface of partial uneven color, appear spot mark, stripes and hue and disorderly phenomenon, the reason is mainly due to the construction process, construction paint is not fully mix, daub is uneven and coating components of metamorphism.

3, efflorescence on the surface of problem is refers to the construction work is completed, the surface coating of appear white phenomenon, the reasons are: the humidity in the air temperature is too high or too low, the water vapor frost in the film, causing the inside of the curing agent amine exhalation, produce white mist was concentrated on the surface.

wrinkle, corrugate fisheye problem is in the process of dry coating surface layer by layer and the difference between drying speed contraction tucked up top layer coating surface wrinkles uneven phenomenon such as linear or no rules; Fisheye coating after construction is part of the coating can be painted surfaces exist or uneven with coating foreign influence of coating adhesion have shrunk and reveal the coated surface phenomenon; Was due to the sharp volatile solvent paint after coating added to the paint liquid and form many round circle or like leather pores of needle holes.

5, wrinkling, pinhole problems

coating surface appear wrinkling phenomenon, the main reason is that paint to consolidate internal and external layer of surface layer caused by the drying speed is not peeling, pinhole because the curing agent is mixed with paint, in coating produced by mixing a large number of air bubbles, bubbles in the process of curing escape, leave a mark in the film as pinhole.

6, crater hole problems

the uneven density or filler dispersion deficiency will lead to the ground like a non-stick oil a circular hole, hole we called craters. Before the solution is the construction must be carefully check the base level, there is a problem need to take care of, then can be construction epoxy floor paint. Choose the packing with good dispersibility, and strengthen the management of material quality work.

7, rough, cracking problem

rough phenomenon refers to the surface in granular material with different size, the main reason is that floor coating is not easy to dissolve impurity is contained in and outside the dust caused by. Surface cracking phenomenon because of raw materials and construction quality problems, resulting in a decline in lacquer layer adhesion and under external force, peel cracking phenomenon.

8, fall off show the fullness of bad problems

lose falls off because the floor crack on the substrate under the action of external force, coating adhesion into pieces or whole zhang jie on the surface of the skin from physical phenomena: grinning and not enough fullness was probably the cause of the problem of raw materials and construction. In epoxy floor paint want do be sure to choose good materials and professional construction team for professional use is the guarantee of quality.

9, curing slow

is slow curing epoxy resin material in the special low temperature ( 10° C) Slow curing reaction. 5° It's absolutely prohibited construction C. The phenomenon and the viscosity has a lot to do, the lower the temperature, the higher the viscosity will be, then it will be hard. Curing time is too long will cause the coating with dust, sand and other stolen goods, and even slow down the time limit for a project. Still is in the construction site and the solvent can also cause curing slow, because the evaporation of the solvent will take away heat and cooling coating.
