Negative ion wall paint is a kind of wall paint that people choose more now. Next, let's take a good look at it. How to choose a barrel of anionic wall paint
How to choose a barrel of anionic wall paint? Check the opacity, because the paint 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 smaller 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 the coated substrate due to the adhesive force and the 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 depends on its viscosity. Viscosity refers to the viscosity of coating, which can be measured by coating viscosity measurement. Viscosity is an important index of coating performance and can have a great influence on storage stability, processability and film-forming performance of coating. Because the coating is easy to fall off too thin, but if it is too thick and easy to apply, 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 granularity and dispersion uniformity of the coating. Delicious directly affects the smoothness, gloss and air permeability of the coating surface. Generally, the finer the coating, the more expensive it is. Do you remember this selection skill of a bucket of negative ion wall paint? Construction steps of wall topcoat
Basic treatment: wipe with loose cement mortar on the clean wall. The crack area is usually covered with kraft paper tape and white latex. Generally speaking, light walls and non-load-bearing walls and other patches that require heat will better choose relatively small crack grids, slightly better textures and white latex walls or grids.
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 the shell can cut the hair, saving time and effort. Brush the interface agent evenly.
wall level: the wall plastering is uneven, and the error of the wall is less than 3mm, so it needs to be successful to realize the uneven wall. If the angle of yin and yang is not straight, you need to use gypsum directly
Batch putty: it is best to use high-density and high-strength putty, and the putty should be approved for three times. The first pass is usually thick because it involves leveling. The second and third times were thinner, mainly because the light was collected, so the wall looked smooth and flat. After three times of approval, the thickness of putty should not exceed 3 mm, otherwise it will crack easily.
Abrasive: Abrasive 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. After polishing, the wall must be thoroughly cleaned to avoid excessive dust and affect the adhesion of paint. The difference of protrusions is not more than 3 mm.
priming paint: the priming paint should have uniform 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: if the putty is finished, it may lead to defects. Under normal circumstances, you can only see clearly after cleaning 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 film thickness, feel and hardness. Choose a better tool. Brushing mainly deals with the edge, the indirect part of each roller and the direction of the pattern. Top coat can be wiped twice.
choosing a good type of wall paint and deeply understanding the construction steps will be the guarantee of wall decoration.
