3 operating process
3.1 Process flow:
Grass-roots treatment → spray, brush glue → fill the gap, the local scraping putty → gypsum wall Patchwork →
Full of scraping putty → brush, spray the first pass → re-find the putty → brush, spray the second time pulp → brush, spray the exchange paste
3.2 Basic treatment: the surface of the concrete wall of floating sand, dust, pimple, etc. to remove the surface, the surface of the release agent, oil and other applications alkaline (caustic soda: water = 1:10) clean brush, and then rinse off the wall with water And the like.
3.3 spray, brush glue: putty in the concrete wall before the first spray, brush a glue (weight ratio of water: emulsion = 5: 1), pay attention to spray, brush to be uniform, not omission.
3.4 fill the gap, local scraping putty, water gypsum wall cracks and potholes will not flatten the injustice, and the wild putty net, to be putty after drying with 1 sandpaper polished, and the dust and other clean.
3.5 Gypsum board wall Patchwork: Application of caulking at the joints filled with putty, the paste layer of glass mesh or silk cloth, with cloth emulsion will be stuck in the patchwork, the stick should be Braba Straight, paste flat, and scraping plaster putty together.
3.6 full of putty putty: According to the different wall and the grass-roots level of living requirements of the different, the number of times and putty material is also different. The general situation is three times, putty with the ratio of weight ratio, there are two, one for indoor putty, the mixture ratio: polyvinyl acetate emulsion (ie white latex): talc or large white powder: 2% Methyl cellulose solution = 1: 5: 3.5; second is applied to the external walls, kitchen, toilet, bathroom putty, the mixture ratio: polyvinyl acetate emulsion: cement: water = 1: 5: 1. Scraping putty should be horizontal and vertical scraping, and pay attention to then and closing the first time when the putty to scratch the net, every time the dry putty should be grinding paper, will be putty grinding grinding dust will be cleaned up. If the surface layer to be painted with the color of the slurry, the putty should also be mixed with the appropriate amount of surface layer with the color of color coordination.
3.7 Brush, spray the first pass Pulp: brush, spray the door before the window should be the first circle with a row of brushes, such as the wall and ceiling for the two colors should be used in the color line at the line and brush 20cm wide To facilitate access Cha, and then a large area system spray. Brush, spray sequence after the roof should be the first wall, the first on the order after the next. Such as spray nozzle when the nozzle from the wall should be 20 ~ 30cm, moving speed should be smooth, so that uniform coating thickness. Such as the top plate for the groove plate, the first should be sprayed around the inner corners of the concave and then spray the middle plane, plasma live ratio and modulation methods are as follows:
3.7.1 Modulating lime slurry:
3.7.1.1 The lime block into the container by adding appropriate amount of water, such as ash and then the proportion of aging should be added in the water should be added. The mixing ratio is lime: water = 1: 6 (weight ratio).

5.2 finished brush (spray) pulp finished product should be done to protect the work to prevent other processes of product contamination and damage.
5.3 indoor pulp live repair, attention should be paid to the installation of electric switches, plugs, lamps and other electrical products and equipment, pipeline protection, prevent brush (spray) pulp caused by pollution.
5.4 To reduce pollution, should be preceded by a circle of the window with a row of brushes, and then a large area of live slurry application work.
5.5 Brush (spray) slurry should be completed before the surface layer of protection, to prevent fall caused by pollution.
5.6 The walls and floors of the oil workers shall be screened and protected before application.
5.7 Moving sprinkler, spraying machine and other construction tools is strictly prohibited on the ground drag, to prevent damage to the surface layer.
Attention should be paid to the quality of the pass
6.1 Brush (spray) slurry engineering or grass-roots level of the overall water content: concrete and plaster surface water-based and emulsion slurry, the moisture content of not more than 10%, to prevent peeling.
6.2 Brush (spray) Putty putty used in the project, should be solid and solid, not powder, skin and cracks. Use of water-resistant putty should be used when the paint is to be applied to the exterior wall, kitchen, bathroom, toilet, etc., and to the surface of wood floor.
6.3 brush (spray) slurry surface roughness: the main reason is the primary treatment is not complete, such as grinding uneven, not putty putty putty net, dry polished uneven, clean up the net, large white fineness is not enough, nozzle aperture, Causing the surface slurry particles rough.
6.4 pulp cracking: the main reason is the grass-roots dust did not clean up the wall uneven, putty thick or before the Road putty is not dry tightly followed by scraping two putty, which is putty dry after the formation of cracks to crack pulp pulp crack .
6.5 peeling: brush (spray) slurry layer is too thick, the amount of glue within the surface layer is too large, low-level glue less strength, dry, the surface layer of slurry to form a hard shell cracking cracking. Therefore, we should grasp the amount of glue within the pulp, in order to increase the bonding strength of pulp and grass-roots level, in the brush (spray) before the slurry brush (spray) a glue.
6.6 out of powder: the main reason is the surface layer of slurry in the amount of glue used, in order to solve the problem of powder out, in the first good slurry with some more emulsion to increase the amount of plastic, with the new slurry with the powder out Surface layer to re-brush (spray) a Road, this glue called "to a sweep glue" can.
6.7 anti-alkali, bite color: the main reason is the wall wet, or dry and wet wall inconsistencies; due to the rush time period pulp with each too tight, before the pulp did not dry on the spray under the slurry; After the fire furnace wall yellowing; also because the indoor running water, water leakage after the formation of water marks. The solution is to use warm winter heating or electric furnace, the wall drying, pulp can not be too many times with the live too tight, should follow a reasonable construction sequence.
6.8 flow fall: the main reason is the wet road, pulp and more difficult to dry glue, spray slurry thick and so on. Should be dry to the wall after the brush (spray) slurry, brush (spray) slurry is best to set someone responsible for the nozzle to move evenly. With a special person to master with pulp to ensure that the right mix.
6.9 through the end: the main reason is the grass-roots surface is too smooth or oil on the surface did not clean, slurry brush (spray) curing up, or because of poor consistency with the pulp when the pulp is too thin, sprayed several times is not covered. Spraying slurry from the wall 20 ~ 30cm, moving speed is uniform, do not leak spray and so on.
6.10 gypsum board wall cracks at the crack: the main reason is not required to install the gypsum board indwelling gap; suture to deal with sloppy, do not follow the rules paste glass mesh cloth, do not seriously capped with caulking to caulk. Resulting in putty dry shrinkage cracking.
6.11 outdoor brush (spray) pulp and paint or paint then Cha-color line is not clear: the main reason is poor technical quality, construction is not serious.
6.12 wrinkles, cracking: the main reason is not dry after the slurry brush caused by the pulp skin wrinkles, should strengthen the finished product
The process standards for industrial and civil construction of the general lime slurry, white pulp, can silver paste, polymer cement and other brush (spray) slurry project.
