Home decoration construction manual latex paint project

Introduction of latex paint dressings and tools:
dressing:
Anti-rust paint: Self-tapping on gypsum board to prevent rust.
Gypsum powder and white latex: After the two are mixed, they are given a crack in the wall to prevent cracking.
Bandages, kraft paper, indeed cloth: special anti-cracking treatment. Some walls have cracks over a large area, and they need to be fully clothed.
Interface agent: In front of the batch wall, glue to the wall surface, the purpose is: make the putty and the wall base layer more firmly.
Finished putty: The main component of the latex paint base layer. Make the wall evener.
Sandpaper: After the putty is approved, sand it with sandpaper. Make the wall evener. 360 sandpaper is generally used.
Separation paper: It is mainly to protect the wooden parts connected with the wall, prevent the putty from being sent to the wood, and prevent brushing onto the wood when painting.
tool:
Roller: The main tool of the roll coating process, which is divided into "long hair and short hair".
Wool brush: Auxiliary tool for roller coating process. Inside the internal corners and light channels, wool brush should be used where the roller cannot reach.
Airless Sprayer: Latex paint can also be sprayed. The spurt is more smooth, delicate, no color difference, and the construction is fast.
Latex paint construction process:
Construction process:
Inspection of the original building structure (to see if there is empty drums, severe uneven walls) - preliminary treatment of empty drums and severely uneven walls - anti-rust treatment of self-tapping on the gypsum board - Gypsum board seams on the wall surface, ceiling gypsum board seams crack prevention treatment - the wall of the yin and yang angle to straighten the line - a lot of batches of walls two to three times - No. 360 sandpaper grinding (must use light bulbs According to the polishing, after the inspection and acceptance by Party A, the paint is started (or the primer is applied once again) - the sandpaper on the wall base is printed and the pinholes are repaired. After the inspection and acceptance by Party A, the last paint is done. Acceptance process:
The quality control of latex paints mainly depends on the acceptance in stages. Only the acceptance of each item is passed. Finally, there is a quality latex paint project which is divided into four stages at least:

Before large-scale wall-pickling, initial treatment is performed on whether the wall surface has empty drums or serious irregularities.
After the worker polishes the wall surface, the grass-roots level is checked (flatness, verticality) before painting.
After the first pass of latex paint, the workers had to make replenishment work and wait for the completion of repairs before accepting it again.
Finished acceptance of latex paint. About latex paint interface agent:
The role of the interface agent:
The use of glue makes the putty and wall more solid.
Sweep dust off the walls to avoid emptying the putty and walls.
Interface agent types:
107 glue as the main component: As the main component of 107 glue is "polyvinyl formal" formaldehyde content is high, but was prohibited by the state's order.
With 801 glue as the main component: 801 glue is a substitute product of 107 glue, with low formaldehyde content, which is commonly used by many decoration companies.
Interface agent usage method:
After the painter enters the field, use a roller to roll 108 glue directly on the wall surface and top surface, and then add the putty. This putty is more solid with the grass roots.
The treatment of the old room wall:
Walls that need to be walled: The 888 paint is sure to be shoveled because he is not water proof, putty putty, it is peeling. Some of the real estate projects are ashed because they are poorly glued, water-resistant, and even environmentally unfriendly. The strength of the finished putty is relatively large, and it is possible to pick up the original base putty. For hollow areas with walls, empty the hollows.
What about the original latex paint? If the original wall itself is a latex paint, then look at the flatness of the grass, if you can, then you can paint directly on it. If the original wall surface roughness is not enough, you need to polish, brush the interface agent, and then grant putty and sanding.
How to do if there is a lot of cracks in the original wall? If there are many cracks on the wall, it is best to stick wallpaper, or use anti-cracking quality latex paint, at the same time on the wall crack at the place of a good cloth or full plasterboard.
Grassroots treatment process and precautions:
Process: Acceptance of the wall surface (Disposal of empty drums, severely uneven areas, first treatment) - Self-tapping of plasterboards for rust prevention (brush anti-rust paint) - Gypsum board joints, wall joints Prevent cracking at places and wall slots (supplement plaster, bandages) - All yin and yang corners are straight and flat on the top - approved putty two times - No. 360 sandpaper (using a light bulb to polish )
special attention items:

After the painter entered the site, he inspected the original wall surface and discovered problems such as emptying, cracking, etc., and dealt with it first.
Yin Yang corner to play straight line.
If you install a wooden finished baseboard, you must pay special attention to the flatness of the baseboard. If it is not flat, you cannot see it at that time. After the skirting board is installed, you can see a gap or a kick. The line is bent.
Special attention should be paid to the area near the lamp, near the lamp trough, under the spotlight, all kinds of modeling walls, and the entrance wall. Slightly uneven, it is easy to see and reduce the effect of decoration. Yin Yang angle construction notes:
1, yin and yang straight processing.
Respond to the internal corner line with plaster to find straight.
Yang angle straight with a ruler.
2, Yang angle anti-collision, bump treatment.
Consider making small rounded corners.
Make dark corners with cement mortar.
Or use metal bandages as a protective horn.
3, yin and yang corner guarantees Founder:
Many of the wall's inside corners are a lot worse, and if you use a straight line to make up for it, the wall may have to find a thick patch. If you find a thick patch, you will find problems such as emptying, falling off, etc., and the inside corner of the wall will no longer be repaired. It is 90 degrees, but it is very troublesome not to find straight.
The more scientific approach is to check the inside corner. If there are many mistakes, then there must be a high place. First knock down the high place and then hit the straight line. The inside corner is basically 90 degrees. Also straightened.
4, Yin corner brushing flowers:
Because the inner corner is painted at the end, there are times when the tone of the paint is reduced, not enough to brush the inner corner, and then paint is adjusted to cause a color difference. Or because the shade of the paint is too much water, there is a color difference with the large surface of the wall.
There are many situations where the top surface is painted white and the walls are of other colors, where the color meets is rough. In particular, the color of a wall is different from the color of other walls. The inside corners must pay special attention.
Treatment of surface smoothness of roof latex paint:
Nowadays, commercial housing has more cast-in-place roofs. The problem with cast-in-place roofs is that the top surface is very uneven and most of them fall down in the middle to form a pot bottom, and some of the top surfaces can be wrong at 4 to 5 centimeters; some have top surfaces. Like a wavy shape, it looks very ugly after being renovated or facing the light. There are no specific requirements for the top surface in the national standards. Because the top surface cannot be approved to be too thick, it is easy to crack and fall off, and a safety accident occurs. However, it is unattractive and very ugly, which seriously reduces the overall effect of decoration.
solution:
Full ceiling. The unevenness on the top surface can be effectively solved, but the cost is high and the height of the room is reduced. If it is not the top floor of the villa, it is not recommended.
Using plaster for repair, you can almost find a thickness of about 2cm. Basically solved the problem of top unevenness. Remember: You can't directly use the wall putty to find the fill, the most likely to crack, fall off. Gypsum board ceiling, wall gap treatment:
Gypsum board joints, gypsum board and wall joints should have a gap of about 3mm, used to prevent cracking. If there is no gap, then use a wallpaper knife to pull out a crack to prevent cracking. The specific construction process is: to open the seam with a wallpaper knife with no gaps 3mm gap - use gypsum powder mixed with white latex to fill the gap - paste the bandage (dead cloth or kraft paper) - approved putty - sanding - paint The circuit of the wall modification slotted: to use plaster fill, do not use cement mortar (cement mortar is not as tough as the plaster, easy to crack). If you use cement mortar to make up, you can't make up for the same level as the wall surface. You should make it slightly lower, and then use gypsum to make up for it. This will make insurance more. All gypsum board joints, plasterboard and wall joints. There are many painters who do not handle the joints on the inside of the lamp trough and will easily crack in the future.
Waterproof rate of latex paint, matters needing attention. - Note that the original paint:
Watering rate of latex paint:
Generally: 20% to 30%, up to no more than 40%. However, paints with heavy colors cannot be mixed with water (easily produce color differences).
Latex paint is mixed with water: it can cause the hiding power of the paint film to decrease, the color becomes lighter, the paint film powders off, the performance is reduced, and the paint surface loses light.
Less water: the pattern will become bigger and affect the appearance. If the water is not exchanged or the water is low, it can be solved by rolling it over again.
Color paint modulation method:
1, buy color fine back, the workers themselves manually adjusted.
2, the computer paint, adjust the paint, and then added to the white paint, the same color number, but more than mixed with heavy colors.
3, the computer directly out of finished paint, buy it back to direct construction.
pay attention:
Heavy paint, try not to dilute water, easy to produce color.
Adjust the color paint before filling with water, filling a bottle with a mineral water bottle, used during maintenance, basically no color. If it is mixed with water, the paint quality of the latex paint will be reduced, and it will become smelly after a while.
Brush paint usually brush several times? Do not use brush primer?
How does a decoration company define how many times to paint?
General decoration company's budget is marked with: Latex paint three times. In fact, most of them have brushed twice, so only to say that brush three times, because of which to find complements for it again, to find complement can not be considered, of course, because only partial use putty to find what.
General brush a few times?
General primer again, topcoat two times. Or brush the finish twice.
The role of primer:
Effectively prevent the infiltration of alkaline substances in the wall caused by discoloration of latex paint, but also can reduce the amount of topcoat used, while increasing the adhesion of latex paint, to avoid peeling.
Due to the humid climate in the south, the paint surface is easy to mold. Therefore, the southern region has more primers.
Many primers have a strong hiding power and can effectively cover sandpaper, which is very useful for topcoats with poor hiding power.
The importance of latex paint replenishment:
Why do latex paints need to be repaired? After the putty is polished, the coarse grains in the putty are polished down to form a small pit. At the same time, the wall surface is formed with a line of sandpaper due to the use of sandpaper. Before the unpainted paint, these small pits and sandpaper were covered by polished powder and could not be seen. After ordinary workers brushed the paint, the pits and sandpaper were printed. Then use the light bulb to look for a patch again, you can put most of the sand eyes, sandpaper printed modified. Brush the last time the paint, the wall is close to perfect.
How to find supplements? Let workers use the light bulbs to carefully look for the wall and the top surface, especially the walls of the human eye to look directly at the visible range, near the lights, each modeling wall and other important locations. After the workers have been repaired, they must not be bothered as owners. They use light bulbs to inspect and find problems and promptly rectify the workers. Workers are not allowed to brush the last pass before they pass inspection. Some workers often say: "It is impossible to have no problems at all." Can not have this idea, find the problem, immediately seek compensation, as far as possible to achieve perfection, after all, it is not costly to find repair, survival and then repair it trouble. In fact, after the completion of the latex paint, there will be some pitting or sandpaper marks. At that time, that kind of idea can still be achieved.
Spray paint and brush paint comparison:
Spray paint: The paint machine is more expensive, and the general painter is not configured. The advantages of painting are: quick construction, good flatness, and poor texture. The disadvantages are: large paint loss, late maintenance trouble, because the late maintenance, the workers can no longer pull the painting machine over maintenance, can only use the brush, brush out with the texture of the spray is certainly different.
Paint: Construction is relatively slow. However, the varnish has a rolling texture and pattern and is easy to maintain. The disadvantages are: the effect of large-surface roller coating is different from that of the inside corner and the inside of the lamp slot, and there are texture differences. At present, many paint companies have promised to spray paintings for the owners free of charge, but they are basically not responsible for grassroots processing, and the primary treatment of latex paint is the most important because the grassroots problems directly reduce the final decorative effect of latex paint. Coupled with the relatively large loss of paint, I personally think it is not particularly affordable.
Special effect paint introduction: liquid wallpaper, texture paint:
What is liquid wallpaper? The so-called liquid wallpaper is: through a special tool to paint a variety of patterns on the wall surface. Because he is a paint, he calls it: liquid wallpaper. The advantages of liquid wallpaper are: it is more texture and level than ordinary latex paint, and its color is more abundant. Compared with ordinary wallpaper: no edge, blisters, no seams, long life and other advantages. The construction of liquid wallpaper is almost the same as the construction of latex paint, or as "special latex paint". The construction process is: primary putty putty, sanding, brush primer, knurling or printing.
Texture paint texture paint is similar to liquid wallpaper, but also requires professional tools. His sense of hierarchy is even more obvious. He uses spray guns or squeegees to make a variety of bumpy patterns on the wall. Some are: After making a pattern effect, spray paint again to achieve the final effect. Whether it is liquid wallpaper or texture paint, their basic treatment is the same as ordinary latex paint: approved putty, sanding, brush primer. The difference is that liquid wallpaper does not use a roller on the top coat but uses a special printing roller or a screen to print the pattern on the wall. Texture paint is a special spray gun to spray a special paint on the wall, so that the wall becomes uneven or use scraper and other tools to make the wall texture effect.

Ion-exchange resins are widely used in different separation, purification, and decontamination processes. The most common examples are water softening and water purification. In many cases ion-exchange resins were introduced in such processes as a more flexible alternative to the use of natural or artificial zeolites. Also, ion exchange resins are highly effective in the biodiesel filtration process.                                                           SY-007 is a sort o fcation exchange resin that has sulfonic group(-SO3H) in the styrene-diethylene benzene copolymer with 7% cross-linked degree.It is used mainly to soft hard water and produce pure  water,as well as used in the hydro-metallurgy and sugar producing and medicine and nosodium glutamate industry, it can be used as catalyzer and dehydrating agent.                                                                                           SY-206 is a sort of Anion Exchange Resin that has quaternary ammonium group[-N(CH3)3OH]in the styrene-diethylene benzene copolymer with 7% cross linking degree.It is used mainly to produce pure water and treat waste water and extract tungsten and molybdenum in biochemical product and hydro-metallurgy.                                                                                                                                                       SY-D301 is a sort of anion exchange resin thathas tertiary amine group[-N(CH3)2] in the styrene-diethylene benzene copolymer with macroporous structure.Itis used mainly to produce pure water and ultra pure water,especially suitable for the treatment of the water resource with highcontent salt and organic substance,as well as treat waste water which contains chrome and decolorize sugar solution and so on.
