Interior wall coatings in the country's total use of architectural coatings accounted for about 60%, it is a large number of wide-ranging building decoration materials. The inner wall coating varieties on the market have synthetic resin emulsion inner wall coating (commonly known as latex paint), water-soluble interior wall coating, polyethylene alcohol and water glass as the main film-forming substances, including a variety of modified economical coatings, colorful inner wall coatings including water-packed oil type and water-packed water type two. In addition, there are fiber-like coatings, imitation porcelain coatings, suede coatings and

ordinary putty construction methods: paint construction, the need to use putty to flatten the wall, general use of 821 plaster putty, can also be used cellulose white putty or 107 glue putty. The latter has been used less often, but the construction methods are mostly the same. First of all, the grass-roots dirt, oil traces removed, brush a diluted 107 glue, and so dry before applying putty. Stir the putty powder with water and use it well. Usually after the batch scraping two lanes are completed, the polishing is smooth. The plaster putty is used up within the specified time.
method of water-resistant putty: the grass-roots surface requires solid, clean, no oil pollution. Before batching putty, paint a back cover liquid at the base for backing treatment. Usually batch scraping two, do not need to scrape too thick, and strive for uniform. Water-resistant putty generally does not need special polishing, if there is a local need to repair can be gently polished, after grinding the surface dust in time to remove clean. Stainless steel or rubber scrapers should be used to avoid rust.
2 primer
in the past interior wall paint construction often does not need to close the primer. However, from the actual use of the process and foreign advanced experience, the use of closed primer to ensure the quality of the process has a great role.
3 must be constructed according to the construction method prescribed by the coating
in the inner wall coating, latex coating occupies a large proportion, usually using the construction method of roller coating and brush coating. In addition, you can also take spraying, smearing, scraping and other construction methods. It can be used alone or mixed. Roller coating construction operation is simple, non-professional construction personnel can operate on their own. Different kinds of rollers can be used to paint different patterns. When applying the roller, pay attention to the amount of suction on the wool roller. Can not be too much can not be too little, pulp must be appropriate and uniform. When rollers are applied to the wall, they are constructed in a bottom-up way so that they do not cause flow. When the paint of the wool roller is used up by 50%, it should be coated and then rolled, which is conducive to long-term construction operation.
