Interior wall coating is one of the most common decorative materials used in home decoration. It has many advantages such as convenient construction, hiding power (measured by opacity paper), strong color, scrub resistance and so on. However, problems may occur if the operation or handling is improper during the construction process.
1. Uneven color of the base layer The high and low temperature test chambers are of different color and are not treated, which will result in uneven color of the coating. It must be covered by a full putty or a primer; a coating with strong hiding power, according to the specified ratio Dilution, brushing according to the specified number can also avoid the phenomenon of uneven color; in addition, when choosing the paint, please pay attention to the same manufacturer, the same variety, the same batch of products, otherwise the color base will appear.
2, the surface is rough,
There are many reasons for this type of problem: for example, the base layer is untreated, clean, the used brush has sand, debris or the operating environment is not clean, dust and dirt fall on the newly painted paint, etc. .
Avoid measures: the base layer should be clean and flat. It must be put full of putty according to the requirements, and sanded with sandpaper. The used brush should be cleaned in time, carefully inspected, and the paint and environment should be protected from dust during construction.
3, the skin if the base layer is too smooth, or oily, dust, it is easy to make the paint adhesion is not strong, resulting in peeling phenomenon; In addition, the putty is not firmly bonded, the coating gel is large, forming a "outside focus" In the state of the coating film, the surface layer is also prone to cracking and peeling in the case of uneven temperature or humidity. The precautionary measure is to use a steel wire to smooth the base layer and clean it. The oil stain should be degreased with a suitable solvent and rinsed with water. When it is necessary to apply the primer, it is best to use the product matching the top coat. The coating should not be too thick, so as to cover the base layer without bottoming, the coating film is full and uniform, and the color is consistent; the different putty is selected according to different base layers, so that the bonding strength of the putty and the bonding strength of the coating can be adapted to each other.
In addition, it should be noted during the construction that the base layer must be dry before painting, and the finished parts should be protected in time without the need for finishing parts and finishing parts. &nb electronic balance sp; centrifuge & color wheel nbsp;
