Paint knowledge | painting the perfect wall paint construction strategy

Core tip: wall painting is a very important part of home decoration and the last step of wall construction Good wall paint construction can not only bring a bright appearance to the home, but also cover up the defects of concealed project construction The following decoration net will explain in detail all aspects involved in the construction of wall paint, and teach you to paint a super perfect wall Materials and tools should be prepared in all aspects before the formal painting on the wall The preparation of wall paint construction mainly includes material preparation, tool preparation and working environment Let's take a look at the preparations to be done before painting the wall paint 1 Material preparation Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: wall painting is a very important part of home decoration, but also the last step of wall construction Good wall paint construction can not only bring a bright appearance to the home, but also cover up the defects of concealed project construction The following decoration net will explain all aspects involved in the construction of wall paint in detail, and teach you to paint a super perfect wall Materials and tools should be prepared at the right time Before the formal painting on the wall, preparations should be made in all aspects The preparation of wall paint construction mainly includes material preparation, tool preparation and working environment Let's take a look at the preparations to be done before painting the wall paint The materials needed for wall painting mainly include cement mortar, interface agent, putty powder, wall paint, etc First, prepare the materials to be used, and then according to the product description, modulate according to different proportion After preparing the required materials, don't forget to check whether the tools for painting are complete Common tools for wall painting include color paper, kraft paper, roller, brush, putty knife, sandpaper, etc Tools preparation In addition, the tools that may be used include blade, paint spray gun, ink bucket line snapping, fiber mesh, high stool, scaffold board, broom, wiping cloth, etc The temperature and humidity of the construction site shall be appropriate, and the sanitary conditions, light conditions and ventilation conditions shall be good In order to paint the most perfect wall, family friends had better construct in a more suitable environment Attention shall be paid to the process flow of wall painting After the preparation work is done, the construction of wall paint can be started To paint a perfect wall, you need to follow a certain technological process and brush step by step Next, let's see the specific steps of wall painting, what are the key points of painting, and what should be paid attention to Each step has its own operation method and construction requirements When painting the wall, each step should be done well according to the specific requirements At the same time, it also explains in detail the two steps of anti cracking treatment and wall leveling in the wall paint construction, so that everyone can understand the wall paint construction more clearly When decorating, after measuring the advantages and disadvantages of various painting methods, choose the most appropriate painting method according to your own preferences Choose When processing, the place with cracks on the wall is generally pasted with kraft paper tape and white emulsion Generally, non load bearing walls such as light body walls and thermal insulation walls need to be pasted with cloth When pasting, try to choose a better quality wall cloth and white emulsion or grid cloth, and the grid cloth will have a better anti crack effect How to level the wall? How to level the wall? Wall leveling also affects the final effect of the whole wall painting No matter it's a new house or an old house, the wall can't be completely flat, and the internal and external corners can't be completely vertical Therefore, the uneven part of the wall should be leveled with plastering plaster, so that the error of the wall does not exceed 3mm If the internal and external corners are not straight, they also need to be plastered and straightened with a guiding rule How to avoid problems and how to save them when they occur? Let's learn about the common problems and causes of wall painting and the solutions to the problems It is mainly due to the excessive dilution of the paint and the excessive amount of painting at one time
solution: the paint shall be diluted in strict accordance with the proportion; when brushing, the thickness of the coating shall be grasped, and the coating shall be brushed quickly and evenly If local sagging is found, the brush shall be straightened immediately, and the redundant paint shall be removed The hardness of the brush shall be appropriate, and the bristles shall not be too long and too soft For spraying, if sagging is found, the paint film can be polished with sandpaper after drying, and then painted The reasons for this problem may be that the contrast between the primer and the top coat is obvious; the paint is excessively diluted and the paint film is too thin; the base of the wall is concave convex surface, usually the convex surface paint film is too thin; the dark and bright colors (such as dark blue, bright red, bright yellow, bright orange, etc.) of the wall top coat have 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 coating layers of the top coat should be increased appropriately The cause of the problem may be too thick or not dry and repainted at one time; the wall base is too loose or rough; the temperature is too low during construction; the paint primer does not match the top coat Crack problem
solution measures: remove the affected paint film; ensure that the paint film is not too thick in one construction; ensure that the front paint film is dry before recoating; if necessary, seal the wall base with a suitable primer; for the internal wall wall base with large roughness, it is recommended to use products with good flexibility; when the wall base temperature is lower than 5 ℃, the wall emulsion paint can not be constructed; the primer and the finish paint should be matched The main reasons are that the base course is not cleaned, there are floating ash and stains, the coating and putty are not sufficiently bonded; the putty adhesion is poor, or the coating film is not enough, and the water resistance of the base material is poor Peeling and peeling The main causes are that the water content in the wall base is too high, and the pressure will blow up the paint film when the water diffuses outwards; the poor waterproof treatment in civil engineering will cause the water to enter the base on the other side of the wall through cracks or unpainted base surface, or there is water leakage, which will damage the paint film when it diffuses Foaming problem
; Before construction, the cracks on the wall base shall be repaired to ensure that the moisture content of the wall base meets the construction requirements If necessary, the paint layer shall be added in the local area 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,
