How to choose a barrel of anionic wall paint How to choose a barrel of anionic wall paint to check the opacity, because the coating is expressed by the minimum uniform coating amount g/m2. The greater the weight, the smaller the hiding power, the stronger the hiding power and the less the amount of paint per unit area.
How to choose a bucket of anionic wall paint to see the adhesion? This indicates the degree of adhesion between the film and the painted surface, and the coated surface may expose the substrate or coat the substrate due to the adhesion and physical and chemical interaction between the film and the substrate. Poor adhesion of wall paint will affect the shape of the wall, because it is easy to fall off.
How to choose a barrel of anionic wall paint to see viscosity? Viscosity refers to the viscosity of paint, which can be measured by measuring the viscosity of paint. Viscosity is an important index of coating performance, which has a great influence on the storage stability, processability and film-forming performance of coatings. Because the coating is too thin and easy to fall off, but too thick and easy to smear, the viscosity of the coating material must be adjusted within a predetermined range.
How to choose a barrel of anionic wall paint depends on the fineness, which indicates the particle size and dispersion uniformity of the paint. Delicious directly affects the smoothness, gloss and air permeability of the coating surface. Generally, the finer the coating, the more expensive it is. Remember the selection skills of this bucket of negative ion wall paint?
Construction steps of wall paint base treatment: smooth the clean wall with loose cement mortar. The crack area is usually covered with kraft paper tape and white latex. Generally speaking, patches that need heat, such as light walls and non-load-bearing walls, will better choose white latex walls or grids with relatively small cracks and slightly better texture.
Brush the interface agent: the interface agent can improve the adhesion of the base layer and avoid the cavitation of the pressure-sensitive adhesive layer, because shells can be sheared, saving time and effort. Evenly brush the interface agent.
Wall level: the wall plastering is uneven, and the error of the wall is less than 3mm, so it is necessary to realize the wall unevenness successfully. If the angle of yin and yang is not straight, you need to walk directly with plaster.
Batch putty: it is best to use high-density and high-strength putty, and batch it for 3 times. The first pass is usually thick because it involves leveling. The second pass and the third pass are thinner, mainly because of good lighting, so the wall looks smoother and flatter. After three times of examination and approval, the thickness of putty should not exceed 3 mm, otherwise it is easy to crack.
Polishing: Polishing is a very important step in the painting stage. After polishing, the final paint effect is very good. Try using finer sandpaper. If the sandpaper is too thick, the sand will become deeper. The polished wall must be thoroughly cleaned to avoid too much dust and affect the adhesion of paint. The difference of protrusions is not more than 3mm.
Foundation: the foundation should have even brushes to ensure that all parts of the wall are brushes. If there is a lot of paint on the wall, it is best to add a little water to the primer to obtain a uniform coating.
Looking for supplements: the putty is used up, which may lead to defects. Under normal circumstances, you can't see clearly until you clean the paint again. I need to find a supplement now. Note that it needs to be softened and then wiped with more water to avoid the color difference between the other wall and the other wall. Brush coating: Do not add too much water, otherwise it will affect the thickness, feel and hardness of the paint film. Choose a better tool. The brush mainly deals with the edge, the indirect part of each roller and the direction of the pattern. The top coat can be rubbed twice.
Choosing a good type of wall paint and deeply understanding the construction steps will be the guarantee of wall decoration.
