Owners who have renovated new houses should know that more paints are used in wall decoration. Paints have good decorative effect and high cost performance and become the most popular wall materials. However, there are many types of paints on the market. Let's introduce the types of paints. .
The liquid paint is in the form of a viscous liquid and is mainly used for oil-soluble paints for materials, metals and water-soluble paints for ceilings and walls. It should be noted that oil-soluble paint must be brushed on the bottom layer of paint.
The shape of solid paint is jelly-like, but it is liquid after being brushed on the wall, and then becomes jelly-like, and the shape is relatively solid and not easy to flow. Solid paint is thicker than ordinary paint, and its adhesion is very strong, which is convenient for primer bonding.
Many wooden furniture also need to be painted. The more commonly used wood lacquer is nitro varnish, which is a transparent lacquer composed of many materials, which is prepared from nitrocellulose, alkyd resin, plasticizer and organic solvent. It belongs to volatile paint, which is characterized by faster drying and softer gloss.
1. Base layer treatment, the purpose of the base layer treatment of the coating project is to first remove the peeling, loose and bulging places on the wall surface, and remove the dust, dirt, mortar and other sundries remaining on the surface of the base layer.
2. Repair the putty, before painting Zhuoyue latex paint, you need to repair the putty. Putty is a kind of thick paste coating, which is an indispensable product in the construction process of paint stucco. Use water gypsum to level the bumped depressions on the wall and other places. After drying, use No. 1 sandpaper to smooth the protrusions, and clean up the floating dust attached to it.
3. In the construction process, the paint is firstly brushed on the wall behind the top plate. When painting the wall, it should be up and down first, and then the wall dust should be wiped off with a cloth. Emulsion paint is generally brushed in proportion, diluted with water and drained evenly. After drying, the putty is replenished and cleaned.
4. Apply the second coat of emulsion thin coating. The construction process is the same as the first time, but it is not advisable to add water to prevent the bottom from being exposed. After drying, use fine sandpaper to polish off the small bumps and brush hairs on the wall. It is best to clean it. clean. In this way, all the matters of the coating construction process can be completed by repeating the construction process until the third time.
1. Wall decoration should first be checked at the base level. Clean and check whether there is dust, oil, impurities on the surface of the base layer, whether the base layer is firm and firm, whether the base layer has cracks, whether it is flat, vertical, and whether it is dry.
2. If the basic treatment is qualified, the basic layer is the guarantee of the appearance and durability of the coating. The cracking of the putty layer and the coating layer caused by the basic factors (such as cement mortar or wall cracking) is a common disease. Treating cracks in the base layer with bandages is a common method for interior wall finishing construction. If the original white wall uses inferior glue, it should be reinforced with an alkali-resistant primer, and the powdered wall should be removed. The wooden board is closed to avoid deformation and color penetration of the board surface.
3. Patching the bandage to ensure the flatness and firmness of the interface around the patch is the key point of patching. Apply two layers of bandage to reduce cracking in the paint layer.
4. If the flatness of the base layer is not enough, it is necessary to scrape and level the local uneven parts first; however, when the deviation of the flatness of the base layer exceeds 8mm, the putty cannot be used for super-thick leveling, and cement mortar should be used for leveling. Smooth the sanding putty to make sure the base layer is roughly flat.
5. The first fully scraped putty construction in coating construction strives not to reveal the bottom, not to leak scratches, and to leave no traces of joints. The second layer of fully scraped putty is generally scraped twice and survived. The time between each putty layer scraping and coating should not be too long, and the thickness of the putty is 1~3mm.
6. If the color latex paint is used, the latex paint should be fully stirred in advance. Uneven stirring will lead to uneven distribution of the color paste in the latex paint. After painting on the wall, the color of the entire wall will be blurred, and the overall effect will be greatly affected.
