In recent years, wall decoration materials have been vigorously developed, and more and more environmentally friendly and newer wall decoration materials have attracted more attention and use. The wall paint is one of them. It is mainly used for the coating of architectural walls, plays a role in decoration and protection, makes the wall more beautiful and tidy, and also plays a role in protecting the building wall surface and prolonging the service life. The next small series for everyone to introduce the purchase of wall paint Raiders.
Wall paint purchase guide
1, view the report
The front of the general wall paint will be marked with the name, trademark, net content, composition, use and precautions. Pay attention to the production date and shelf life, each brand of latex paint labeled shelf life of 1 year to 5 years, as far as possible to buy products with a production date closer.
2, rocking sound
The sound of regular brand latex paint is generally not heard, and it is easy to shake the sound, which proves that latex paint lacks viscosity.
3, can open detection
A look at the water solution, high-quality latex paint is more viscous, milky white liquid, no hard block, uniform after mixing, no odor. Second, look at brushing, take a brush sticky point latex paint, can hang a long wire and continue to fall evenly as well; three try feel, touch with your finger, genuine latex paint should feel smooth and delicate.
4, smell smell
Most non-environmentally friendly coatings have a pungent odor and smell a pungent odor in the paint.
Wall paint acceptance error
1, hand touch off powder quality problems
When checking the wall paint, you usually touch the wall with your hand. Sometimes when the hand touches the wall, many particles will fall off. At this time, many people think that it must be a problem with the paint or construction. However, powder off the wall does not necessarily have to be a problem with the paint. During the construction process, dust will adhere to the wall. After the construction, the powder will fall off. In fact, these are just dust, and they can be solved simply by wiping them off with a clean towel or tweezers.
2. The smoother the wall, the better
Wall paint construction generally adopts two methods: roller coating and spraying. The smoother the spraying construction, the better. However, for roller coating construction, roller-printed walls will always have roller stamps. If the wall is particularly smooth, it may be caused by adding too much water to the paint, which will instead reduce the coating's adhesion and reduce the paint's ability to protect the wall. After the roll coating is applied, look at the knurled print on the wall for evenness and detail.
Wall paint features
1. High hiding power: refers to the minimum amount of paint that is used to uniformly apply the paint to the black and white grid so that the black and white grid is no longer present, expressed in g/m2. The greater the weight is, the weaker the hiding power is, and the stronger the hiding power is, the less the amount of paint per unit area is used.
2, good fineness: refers to the size of the paint particles and the uniformity of the dispersion. Fineness size directly affects the smoothness, gloss, and water permeability of the coating surface. In general, the finer the paint, the more expensive it is.
3, strong adhesion: that the adhesion of the coating and the grass-roots level, the coating and the surface being coated by the physical and chemical interaction between the degree of fastness, the surface can be painted bare wood can also be painted substrates. The wall paint with weak adhesion is easy to fall off, affecting the appearance of the wall.
4, strong viscosity: refers to the viscosity of the paint, you can use the paint viscosity measurement instrument measurement, viscosity is an important indicator of the performance of the coating, for the storage stability of the coating, construction performance and film performance can have a great impact. If the paint is too thick, it will not be easily painted, but it will be too thin and easy to fall. Therefore, the viscosity of the paint must be controlled within a certain range.
Editor's summary: On the wall paint selection Raiders introduced here, I hope to be helpful to everyone. If you want to know more about yourself, you can follow the information on this site.
