Amino paint is generally in baking, spraying amino paint. The paint solvent we use should not be too strong or it will wrinkle. It should be tested in advance. Spray paint is best if a small amount of paint is used. If a large amount of paint is used,
it is recommended to use a real high chlorinated topcoat. Good brightness, good hardness, good anti-counterfeiting.
Polyester paint is generally used for color steel tile. If there are special requirements, water-based coatings can be used. At present, almost all wall coatings are water-based coatings. It is suggested that Fuya waterborne coatings should be used in
Beijing. When buying, you should be optimistic and show that you are buying. At present, the color steel tile used in the market adopts the thermoplastic spraying process. Polyurethane film has excellent weather resistance. However, it can not withstand
acid and alkali corrosion, and its service life is 12-14 years (made by Baosteel), and the paint film is powdered.
Our suggestion must be twice. Why twice? Can't you do it again? The cost of two passes is also high. In the market of topcoat spraying,
the most basic requirement is that the covering plate surface or primer shall not leak, which is the most basic requirement. If the primer can be seen exposed after spraying the top coat, it means that the top coat is too thin and needs to be sprayed
more slowly and carefully, or spray again in the opposite direction. Note that it is best to reverse the direction, as some corners of the wave crest are difficult to spray, so that it can be completely sprayed.
2. As long as there is professional
construction technology, the film thickness must also fully meet the requirements, there is no possibility of any problems. Why do some flake and burst soon after painting? One is that the products are not professional enough; the other is that some treatment
of the roof before construction is not in place and the spraying is too thin
