in the process of room decoration, the paint of wood products is an important construction link, and the quality of paint application has an important impact on the overall effect of the room. The following introduces several commonly used paints and their application methods:

first, nitro paint, including nitro varnish, nitro Matt varnish, nitro paint (mixed paint), etc

II. Alkyd paint, including alkyd varnish, alkyd paint (mixed paint), etc

nitrocellulose paint is a kind of paint widely used by customers at present, with good surface texture. Nitrocellulose paint and alkyd paint cannot be mixed. In decoration, the coating methods of varnish and mixed paint are basically the same

(1) first, apply putty on the painted surface for priming, polish and level with sandpaper after the putty is dry, and brush the first coat of paint (primer)

(2) after the second sandpaper grinding, brush twice with paint, and then polish with sandpaper. By analogy, the varnish shall be applied for at least 7-8 times; The mixed paint shall be applied at least 4-5 times

(3) "varnish grinding back" is the highest requirement for varnish application, and the price is relatively high. It should be applied at least 20 times, and then polished with sandpaper instead of cotton wire after the fifth or sixth time

in addition, there are some differences between varnish and mixed paint in the overall decoration procedure

the application of varnish is completed in two parts: after the carpenter closes, the primer is applied twice to prevent the dust from invading the wood grain during the construction of other projects, and the rest is applied after all other projects are completed

due to its strong coverage, the mixed paint can be applied after all projects are basically completed
