As time goes by, problems such as wall aging, hollowing, peeling, cracking, and powdering gradually appear. These wall problems that appear on the paint film can easily mislead consumers that there is a problem with the quality of latex paint. However, latex paint is only the last step in the complex wall construction process. The complete wall construction includes: base cleaning, wall reinforcement, waterproofing, joint treatment, base leveling, primer application, and topcoat application. , problems with any of the processes may lead to various wall problems in the future. Let’s learn about it with Kannami Paint!
1. Cleaning the base layer
The floating dust and oil stains on the base layer of the wall will affect the adhesion of the construction materials. Therefore, it is necessary to remove dust, scum, etc. before construction, wash the oil stains with detergent, and sweep away the surface dust after drying.
2. Wall reinforcement
Regardless of whether the material of the base wall is old or new, there may be varying degrees of powdering problems on the surface, which will lead to weak bonding of construction materials and eventually large-area delamination on the wall. At this time, the wall reinforcement needs to be painted on the base wall so that it can penetrate into the tiny holes in the wall to strengthen the base surface and enhance adhesion.
3. Waterproofing treatment
Water vapor penetrates and corrodes the wall, causing large areas of mold, efflorescence, and even shedding on the wall. In order to block the intrusion of water vapor and protect the wall, it is essential to paint a waterproof barrier. In addition to wet kitchens and bathrooms that require overall waterproofing, some locations that are prone to water vapor intrusion also need to be waterproofed, such as the walls facing water in the bathroom and the top ceiling of the building.
4. Seam treatment
Due to improper treatment after wall grooving, or building settlement and other reasons, the wall will crack, seriously affecting the aesthetics of the wall. When the cracks are too large, they may also affect the structural safety of the house. These cracks need to be filled with special inlay paste before subsequent wall construction.
5. Base leveling
Leveling is a very important step in wall construction, which is directly related to the final painting effect. When leveling the wall, choosing inappropriate materials can easily cause interlayers. Generally, first use gypsum or cement putty to level the bottom layer. Next, you need to refine the surface of the base layer and scrape the putty on the surface layer to make the surface of the base layer more beautiful. exquisite.
6. Apply primer
The putty layer is usually very alkaline. In order to prevent efflorescence, it is necessary to apply primer. The sealing property of Kanamax primer can block the precipitation of alkaline substances, and its good permeability can penetrate into the internal structure of the substrate, which can reinforce the loose and weak substrate, improve the adhesion between the topcoat and the wall, and avoid The wall surface peels off, which helps maintain the painting effect for a longer period of time.
7. Applying topcoat
Applying topcoat is the last process of wall construction. A good topcoat can provide a delicate and textured paint film. Good weather resistance can ensure that the color of the paint film lasts for a long time and is as beautiful as new. . At the same time, environmental protection is also very important for topcoats. The harmful substances released by topcoats are related to the health of residents and will affect the occupancy time. Have you learned it?
