Coating knowledge: experience sharing of floor coating construction master

Core tip: floor paint has the characteristics of bright, true, beautiful, wear-resistant, waterproof, corrosion-resistant, etc., so now not only many public places are decorated with floor paint, but also some people in the home have begun to use it The construction process of floor paint has been introduced with you, but if not handled properly in the construction, there will be various problems What will happen in the construction of floor paint Problem, how to deal with it? We understand: 1 Floor color penetration refers to the phenomenon that when one kind of coating is applied with another color of paint, the bottom part penetrates into the surface coating and causes the surface coating to change color The main reasons for color penetration are: 1 Primer is not dry, 2 primer Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: floor paint has bright, real, beautiful, wear-resistant, waterproof, corrosion-resistant and other characteristics, so now not only many public places are decorated with floor paint, home furnishing Some people have started to use it I have introduced the construction technology of floor paint to you However, if it is not handled properly in the construction, there will be various problems What problems will occur in the construction of floor paint? How to deal with them? We understand: 1 Floor color penetration refers to a kind of coating When another color of paint is applied, the bottom layer part penetrates into the surface coating film and causes the surface coating film to change color The main reasons for color penetration are: 1 The primer is not dry, 2 The color difference between the primer and the top coat, 3 There is no primer or the base material contains colored substances, 4 There is organic pigment in the primer 2 The paint surface of floor paint is characterized by uneven color, spot, stripe and disordered color on the surface of the coating, which is mainly caused by insufficient mixing, uneven application and deterioration of paint components during construction 3 The problem of floor paint surface whitening refers to the phenomenon of surface coating whitening after the completion of construction There are several reasons: the humidity in the air is too high or the temperature is too low, the water vapor is frosted on the film, resulting in the release of amine in the curing agent, resulting in the white fog on the surface 4 The wrinkle of floor paint is caused by the difference of drying speed between inner layer and surface layer, the surface layer shrinks sharply and collapses upward, resulting in uneven wrinkles or irregular lines on the surface of the coating; the fisheye is the phenomenon that part of the coating film shrinks after the coating construction due to the presence of foreign matters on the surface of the coating or mixed with the coating, resulting in the uneven adhesion of the coating and the appearance of the coating surface; It is the phenomenon that many circular small circles or pinholes like the pores of leather are formed due to the rapid volatilization of solvent after coating, which makes the paint liquid too late to supplement 5 The floor paint is wrinkled and has pinholes The main reason for wrinkle on the surface of the film is that the drying speed of the inner and outer layers of the paint is inconsistent, which causes the surface to gather up the skin and pinholes When the curing agent is mixed with the paint, a large number of bubbles are generated in the paint due to mixing During the curing process, the bubbles continuously escape, leaving traces on the film and become pinholes 6 The uneven density of the base surface or the insufficient dispersion of fillers will lead to the appearance of circular holes on the ground, which are called circular holes The solution is to check the base surface carefully before construction If there is a problem, it needs to be handled carefully before construction of epoxy floor paint Select the filler with good dispersion and strengthen the management of material quality 7 The rough and cracking problems of floor paint refer to the appearance of granular substances with different sizes on the surface, which are mainly caused by the impurities and external dust in the floor paint that are not easy to dissolve The surface cracking is caused by the problems of raw materials and construction quality, which leads to the decrease of the adhesion of the paint layer and the phenomenon of peeling and cracking under the influence of external forces 8 Floor paint falling off, poor underfill fullness, falling off is due to the fact that the floor cracking has lost the original adhesion to the substrate, and under the action of external force, the coating becomes a small part or the whole peeling off from the surface: the insufficient underfill and fullness are mostly the problems of raw materials and the reasons for construction In a word, if we want to do well in epoxy floor paint, we must choose good materials and use professional construction team because specialty is the guarantee of quality 9 Too slow curing of floor paint means that the curing reaction of epoxy resin materials becomes slow at a very low temperature (10 ° C) Construction is absolutely prohibited below 5 ° C This phenomenon has a great relationship with viscosity The lower the temperature is, the higher the viscosity will be, so it will be more difficult to construct If the curing time is too long, the coating will be stained with dirt, sand and other spoils, and even the construction period will be delayed Another point is that adding solvent to the construction site will also cause slow curing, because the evaporation of solvent will take part of the heat away and cool the coating [focus on WeChat official account "paint net"; pay attention to surprises, scan code to see if your husband is selling paint..
