In home renovations, paint can be a very big project. It looks like a very simple painting or spraying process, but the real attention is very wide. In particular, the wall is often a large area of ​​paint, once the substrate has not yet been cleaned, or improper paint brushing techniques, it will easily lead to foaming, peeling, peeling, etc. of the paint, which not only loses the appearance but also may cause inconvenience to life. . Next Xiaobian will introduce painter acceptance items and paint construction procedures.
Painter acceptance matters
1. Whether the surface of furniture oil is saturated or not. Make sure there are no blisters, no cracks, and that the paint thickness is uniform and consistent in color.
2. Whether the surface of the furniture varnish has the same thickness, the paint surface is saturated, clean, and there is no particle.
3. Whether the emulsion paint on the wall surface is smooth and uniform, there is no hollowing, blistering, cracking phenomenon.
4, wood and plaster ceiling paint is generally latex paint, the surface should be flat, there is no crack at the board junction.
5. Whether the connection of the ceiling angle line is smooth, there is no obvious misalignment and deformation.
6, wallpaper patchwork is not accurate, no tearing phenomenon. Patterned texture patches should be accurate and error-free.
7. Whether there is no pollution on the wall or no stains.
Paint construction process
1, paint must use high-quality paint. During construction, clean the site and minimize human activities and dust processes.
2, check the cleaning of the grass-roots level, can be used to gently polish the surface burr 400# sandpaper, clean with a clean towel, check whether the surface of the panel stains, damage can be used.
3, all panels and lines should be done after the transparent putty and primer again. After the substrate is cleaned, a transparent putty can be applied. According to the type of the panel, brushing or direct squeegeeing can be applied. The transparent putty can be applied twice. After being coated for 4 hours, it can be ground and polished. The putty should be thin and uniform.
4, putty polished, transparent primer, transparent primer and special clear transparent bottom and curing agent, thinner ratio of 1:0.3:0.8 to 1. The transparent primer should be brushed or sprayed with 200# filter before use and brushed twice. After 4 hours of drying, polish with 400# sandpaper.
5, putty polished, transparent primer, transparent primer and special clear transparent bottom and curing agent, thinner ratio of 1:0.3:0.8 to 1. The transparent primer should be brushed or sprayed with 200# filter before use and brushed twice. After 4 hours of drying, polish with 400# sandpaper.
6. When spraying process is adopted, the site shall be cleaned, and the ground shall be sprayed with dust in a small amount and sprayed evenly.
Kind of paint
1, according to the paint form (powder, liquid)
2. According to the mechanism of film formation (transformed, non-converted)
3, according to the construction method (brush, roller, spray, dip, shower, electrophoresis)
4, according to the drying method (normal temperature drying, drying, moisture curing, steam curing, radiation curing)
5, according to the use of hierarchical points (primer, middle paint, topcoat, putty, etc.)
6, according to the film appearance points (varnish, paint; no light, flat light, matt, high light; hammer paint, embossed paint ...)
7, according to the use of points (auto paint, ship paint, container paint, aircraft paint, home appliances paint ... ...) Marine paint can also be divided into anti-rust coating, anti-corrosion coating, anti-fouling coating, weathering coating according to the characteristics of the use of the site and the application environment , heat-resistant paints and boat primers, hull lacquer, deck lacquer, sign lacquer, oil tank lacquer, battery lacquer, ballast tank paint, ammunition tank paint, living tank paint, and other special function paints.
8, according to paint film performance points (anti-corrosion paint, insulating paint, conductive paint, heat-resistant paint ... ...)
9, according to the film forming material points (alkyd, epoxy, chlorinated rubber, acrylic, polyurethane, ethylene, ...) Each of the above classification methods have their own characteristics, but no matter what kind of classification method can not paint the specific All are included, so there is no unified classification method in the world. China's national standard GB2705-92 uses a classification method based on film-forming substances in paints.
Editor's summary: About the painter's acceptance matters and the paint construction process are introduced here, and I hope to help everyone. If you want to know more about yourself, you can follow the information on this site.
