Paint knowledge: teach you to check whether the paint project is qualified

Core tip: decoration is a very distressing project for the majority of owners, but when it comes to painting, you can celebrate it first, because the hardware of your home is finally finished Although painting is the last process of building construction, it is not careless at all There are many things that need to be handled carefully by painters The following is the Scripture from experienced teacher Fu When there are problems in the process of painting, it can be used as a reference to try not to affect the overall appearance of the wall 1、 Construction process of applying emulsion paint 1 First, clean the base layer, which is not greasy Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: decoration is a very distressing project for the majority of owners, but when it comes to painting, you can celebrate first, because the hard decoration of your home is finally finished Although painting is the last process of building construction, it is not careless at all There are many things that need to be handled carefully by painters The following is the Scripture from experienced teacher Fu When there are problems in the process of painting, it can be used as a reference to try not to affect the overall appearance of the wall 1、 Brush latex paint construction process 1 First, clean the base, scrape and repair the putty, and then grind it flat 2 Fully apply putty and polish it Repeat this operation twice 3 Apply the primer, and after it is completely dry (about 10 days), apply the first coat of paint 4 Check if there is any place that needs to be repaired and make up; paint again 5 Polishing II Solutions to problems encountered in painting The wall surface engineering at home is very important However, when painting the wall surface, a little carelessness may cause serious problems How to avoid these difficult problems and how to save them? Immediately follow Xiaobian to learn how to deal with it 1 Sagging problem: this phenomenon often occurs at the interface (edge angle) between surfaces, where the paint film is thicker than other surfaces Cause: generally, the first is excessive dilution of paint; the second is too much painting at one time Solution: the coating should be diluted in strict accordance with the proportion; when brushing, the coating should be applied quickly and evenly, and at the same time, the coating thickness should be well controlled If local sagging is found, it should be immediately smoothed with a brush; when selecting a brush, pay attention to the hardness of the brush, and the brush hair should not be too long or too soft; if it is spraying, if sagging is found, it can be polished with sandpaper after the paint film is dry, and then painted 2 Problem of poor covering power: normal painting, but the color of the wall base can still be seen, or the overall color is always uneven Reasons: the difference between the primer and the top coat may be too large; the paint is excessively diluted, and the paint film is too thin; the wall base is concave convex surface, usually the convex surface paint film is too thin; the bright red, bright yellow color part, dark color and bright color (such as dark blue, bright red, bright yellow, bright orange, etc.); the wall paint product itself has poor covering power Solution: use the middle layer paint or primer which is similar to the color of the top coat, but slightly lighter; control the dilution ratio; use the roller construction effect is better; for some colors or wall base, the number of layers of the top coat should be increased appropriately 3 Cracking problem: linear, multi angle or indefinite cracks are generated on the wall Reasons: one time painting is too thick or not dry and repainted; the wall base is too loose or rough; the construction temperature is too low; the paint primer does not match the top coat Solution: the affected paint film can be removed; one time construction paint film shall not be too thick; the first paint film shall be completely dry before recoating; suitable primer can be used to seal the wall base; considering the roughness of the inner wall wall base, it is recommended to buy products with good flexibility for brushing; when the wall base temperature is lower than 5 ℃, construction brushing is not allowed; primer and finish paint shall be Matching 4 Peeling and peeling: there are many twists and turns in the paint film until peeling and peeling occurs Causes: the cleaning of the base course is not thorough, the wall surface has floating ash and stains; the adhesion between the coating and the putty is not enough; the adhesion of the putty is poor, or the coating film is not enough, and the water resistance of the base material is poor Solution: the base course shall be cleaned thoroughly; good indoor sanitary conditions shall be maintained during construction; the viscosity of the coating shall be appropriate, and each layer of paint film shall not be too thick, and direct sunlight and strong wind shall be avoided 5 Blistering problem: the film is raised, blistered or cracked Causes: the water content of the wall base is too high, and the paint film is bulged due to the pressure when the water diffuses outwards; the waterproof treatment in civil engineering is poor, which leads the water to enter the base on the other side of the wall through cracks or unpainted base surface; there is water leakage, and the paint film is damaged when the water diffuses Solution: remove all blistering and peeling parts If the problem is caused by the putty on the wall base, remove the putty and re scrape it with a suitable putty Construct in strict accordance with the requirements of the construction specifications to ensure that the waterproof layer of the wall base is well done Repair the cracks on the wall base before construction to ensure that the moisture content of the wall base meets the construction requirements It can be used in some areas Add paint layer to prevent rainwater infiltration 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,
