Interior wall paint engineering technology bottom!

First, materials and appliances necessary
paint, fillers, high stools, footplates, putty trays, rollers, brushes, pens, small paint buckets, sandpaper, rubber scrapers, putty grooves, wipes, cotton wire, half a large bucket and so on.
, operating conditions,
1, the surface should be basically dry, the grass-roots water content should not be greater than 10%.
2, dusting operations have been completed, cross-wall pipes, holes, yin and yang corners, such as the early processing of

.
3, doors and windows should be installed in advance.
4, large-area construction should do a good job before the model, experience qualified before large-scale construction.
, quality requirements
water-based paint coating project quality requirements in line with the "building decoration project construction quality acceptance norms" (GB50210-2001) provisions.
Fourth, process
seal treatment→ repair the wall→ the first scrape putty, grind flat→ the second scrape putty, grind flat →brush the first paint→ make-up putty→ grinding→ brush The second time the paint → grinding flat (light) → brush the third paint
5, construction process
1, scraping putty before spraying on the concrete wall, brushing a glue (water: emulsion for 5:1) to spray evenly, there must be no omission.
2, full of putty, scrape putty should be vertical scraping, that is, the first putty horizontal scrape, the second putty vertical scrape. Pay attention to press and close the putty to scrape clean, each putty dry after applying sandpaper polishing, putty grinding and dusting.
3, paint the first time paint, brush should be up and down. After drying to make up the putty, to make up the putty dry after polishing with sandpaper. After 1 day, brush a second time.
4, in the second operation should not be applied back and forth many times, in order to avoid the release of the first paint film, or the appearance of significant paint brush painting marks, affecting the quality.
5, in the third paint construction, pay attention to the coating cover, in order to keep track of and adjust the tightness of the coating, to ensure the uniformity of the paint color.
, finished product protection
1, the first to clean up the surrounding environment, to prevent dust and affect the quality of painting.
2, shall not pollute the window sill, doors and windows, glass and other completed sub-projects.
3, after the completion of the painted wall, to be properly protected, not to touch, pollution of the wall.
, safety measures
1, all workers should strictly implement and avoid safety operating procedures, strengthen occupational health and safety awareness, on the shelf construction to wear personal protective equipment. Pay special attention to wearing a seat belt.
2, the outer frame should be used before the inspection and maintenance of the entire frame, acceptance of qualified can be used.
3, on scaffolding construction, tiles and small workers should be placed in a place that is not easy to fall, so as not to leave the air to hurt people.
4, construction shall not appear three-dimensional cross-operation.
