General knowledge of coating: surface treatment of base course for construction of epoxy self flowing flat paint

It is suggested that the self leveling coating is a solvent-free, self leveling, particle dense, thick paste epoxy floor coating It has the advantages of high cleanliness, green environmental protection, high gloss, strong and wear-resistant paint film Before the self leveling construction of epoxy, the base surface needs to be cleaned It has certain requirements for the base surface, such as: the strength must reach C25, the ground needs to be flat, and the water should be cut off, there should be no ponding, and it also needs to be clean and dense In order to meet these requirements, base treatment has become an indispensable process Generally, large area of concrete base surface is ground grinded by ground grinding machine, and small area or wall corner is grinded by ground grinding machine 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 Home of coatings: self leveling floor coating is a solvent-free, self leveling, particle dense thick paste epoxy floor coating It has the advantages of high cleanliness, green environmental protection, high gloss, strong and wear-resistant paint film Before the self leveling construction of epoxy, the base surface needs to be cleaned It has certain requirements for the base surface, such as: the strength must reach C25, the ground needs to be flat, and the water should be cut off, there should be no ponding, and it also needs to be clean and dense In order to meet these requirements, base treatment has become an indispensable process Generally, the ground grinding machine is used to grind the large area of concrete base, and the manual grinding is used for small area or wall corner to ensure that the ground surface is free of cement slag and other attachments; if the ground is relatively smooth and the hardness and strength are also relatively good, the sand blasting machine is used to grind the whole surface to form a uniform rough surface, which is conducive to coating adhesion If the ground is flat, acid washing and mechanical methods are generally used Acid pickling method is generally used to deal with oily ground First, clean the concrete surface with salt Hydrochloric acid concentration of 10-15% is suitable When there is no bubble on the ground, wash it with a large amount of water It can also be used with a brush Acid washing method can effectively remove the mud layer, and the roughness of the ground will become more meticulous The mechanical method is suitable for the larger use of the site Firstly, the particles on the ground surface such as sand blasting machine or electric mill shall be removed to increase the adhesion area of the surface, and then the sundries shall be removed by vacuum cleaner If there are pits on the surface, it can be repaired with epoxy mortar or putty Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
