In home decoration, paint is an indispensable product, and there are more and more paint products on the market. However, when it comes to shell powder paint, I believe everyone will not be unfamiliar, but everyone We don’t know much about it, so let’s introduce to you the characteristics of shell powder paint and how to apply shell powder paint.
1. Characteristics of shell powder coating
1. Odor elimination function
Calcium compounds are often used as deodorants in daily life, so shell powder can be effective against indoor smoke, infants, patients, pets, mold and indoor odors. It has the removal effect, especially the adsorption effect on the carbon monoxide and floating dust emitted by smoke indoors.
2. Antibacterial and bacteriostatic effects
The specially fired shell powder film has strong antibacterial and bactericidal effects on Escherichia coli, and is also effective against Salmonella and Glucobacter yellows. It not only has high-performance antibacterial properties, but also has antiseptic and tick-proof functions.
3. Anti-static properties
Shell powder coating is made of specially treated natural multi-microstructured shells as raw material. Its composition is 100% calcium, so it has good anti-static properties.
4. Unique "water breathing" function for regulating air humidity
The calcined LTS shell powder itself has a high-strength porous structure, so it has a good water breathing function. Under low pressure and high humidity conditions, the wall will not Condensation occurs, and in dry conditions, the moisture stored in the wall can be slowly released. Therefore, its breathing function is a regulator of indoor humidity, preventing condensation and the generation of microorganisms, so it is known as a "breathable" paint.
2. How to apply shell powder coating
1. How to apply shell powder coating? Surface treatment of the substrate. In order to make the coating firmly adhere to the surface of the substrate to be painted, the surface of the substrate must be treated before painting. The treatment method varies depending on the properties of the substrate. Generally, cast iron or thick steel is usually sandblasted or shot blasted; thin steel substrates need to be degreased, rusted, and phosphated; the wood surface needs to be polished, bleached, grease removed, and sealed (to prevent paint from penetrating into the deeper layers) ; The surface of new concrete needs to be treated with zinc chloride solution because it contains alkali precipitates; the surface of old concrete should be cleaned of surface loose matter and mildew.
2. How to apply shell powder coating? Scratching putty, if there are any unevenness on the workpiece, you can apply scraping putty (prepared from film-forming substances and a large amount of fillers) in whole or in part. The oxidized and dried putty should be scraped multiple times, and it should not be too thick each time, otherwise it is easy to produce surface. It may not dry out or may shrink and crack over time. After each scraping, it must be fully dried and smoothed with dry or wet sandpaper. Workpieces with high quality requirements should use as little putty as possible.
3. How to apply shell powder coating? Apply the topcoat. The number of coats of topcoat can be determined according to the quality requirements of the work and the specified thickness (generally the coating is required to be uniform and of moderate thickness). Rinse and apply. For new houses with putty base, as long as the walls are flat, clean and free of blistering, mildew, powder loss, etc., rinse and apply. For paint walls with blistering, mildew, cracking, and powder loss, Procedures such as eradication, filling, and polishing must be carried out according to the construction requirements of shell powder. Once the normal wall construction requirements are met, it can be painted. Before rinsing, the original paint wall must be cleaned to ensure there is no floating dust. At the same time, it must be rinsed twice, with a thin layer applied the first time to allow the shell powder to penetrate into the wall, and then rinsed a second time. For secondary decoration of walls, the treatment should be based on the specific conditions of the wall.
4. How to apply shell powder coating? Latex paint wall: If the wall surface is blistered, powdery, or efflorescent, it must be shoveled off. The removed wall surface should be treated with putty primer according to the construction requirements of shell powder. The putty primer must be treated well before construction can begin.
If it is a newly renovated house and there are no problems with the walls, shell powder construction must be carried out by spraying; if you want to extend the service life of the wall, you can polish off the original latex paint base and apply a second layer of putty (shell powder partner) and then add the shell powder.
5. How to apply shell powder coating? Wallpaper: Since wallpaper requires a cured base film, the wall will harden and solidify. The treatment method is to remove the original base film, make a base (putty base or shell powder companion) on top, and then apply shell powder; save The cost-effective method: You can directly re-make a second primer (putty primer or shell powder companion) on the base film without shoveling, and then brush or spray shell powder, but the service life of the wall will be affected to a certain extent.
The above is all the knowledge about the characteristics of shell powder coating and how to apply shell powder coating introduced to you today. If you want to choose a good product, you must first learn more about the relevant knowledge of the product. This is very important. This is a crucial step. I hope the above article can help you.
