nitro paint is simple and easy to construct, easy to repair after damage, with good yellowing resistance, but the film formation of a single time is thin, and the hand feeling is good after a certain number of times This is the first time to talk about wood paint Later, we will introduce its construction process in detail Today, we will talk about the coating method of latex paint First, select tools according to the situation: generally, there are three methods of painting: brush, roll and spray 1 Brush painting, brush painting is a commonly used construction method Advantages: relatively material saving, simple operation, easy operation, strong flexibility and strong adaptability to paint varieties, which can be used for general paint Disadvantages: the manual operation has relatively high labor intensity and low working efficiency, which is not suitable for quick drying paint If the operation is not skilled and the action is not agile, the paint film will also have defects of brush marks, sagging and uneven painting In short, the decorative effect of paint film is very poor Application: fast drying volatile coating 2 Roll coating, the method of using the roller made of wool or other materials and dipping the paint cloth on the surface Advantages: fast speed, suitable for large-area construction, workers construction efficiency is higher than brush coating Disadvantages: inconvenient corner repair, easy to blister, will appear as a pockmarked fish skin effect, do not like pockmarked people are not welcome Moreover, roller coating costs nearly 20% more materials than brush coating, which increases the cost Scope of application: all 3 Advantages of air spraying: fast construction speed Disadvantages: will leave a lot of bubbles on the wall, the effect is very poor Scope of application: outdoor 4 Advantages of high-pressure airless spraying: the high-pressure coating is delivered to the spray gun through the high-pressure hose, and the pressure is released through the spray gun to form atomization, forming a smooth and dense coating on the wall surface, with excellent film effect Disadvantages: it is not popular in China for the time being, but not in other areas Scope of application: the second is to clean the walls The treatment of new and old walls is different: 1 New walls: the water content is very high, so it's not suitable to paint immediately It's better to put them aside for one month before construction, otherwise it's easy to cause wall cracks 2 Old wall: first use wire brush and putty knife to clean the floating particles, garbage and oil on the surface, and then start after it is dry; if there are uneven parts on the wall, after cleaning and drying, first use putty to scrape it once, and fill the cracks There is such a saying in the decoration industry: "whether the paint works well or not, three points to see paint seven points to see painting" So how to effectively carry out painting operations, as the owner is still very necessary to understand 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,
