Paint the wall is to buy the paint yourself or the master buys it

Do the math how much it will cost you to renovate your home

If you do more homework, it is recommended to buy the paint yourself, and the materials and costs can be controlled by yourself, and the quality and expenditure are more guaranteed. But because there are many types of paints on the market, if you don't understand it at all, you should leave it to the master to buy. Because different brands have different internal formulations, the master and the paint shop have long-term cooperation, which is much cheaper than the paint bought by individuals, and the gap even reaches about 20%.

How to tell if paint is good or bad.

1. Packaging. **The paint package is well sealed, there is no leakage, if the package is rusted, it proves that the seal is not good or has been too long. Then carefully check whether the production date is within the expiration date.

2. Quantity. Different paint specifications are different, the weight is also different, it is recommended to take out each can and shake it, if you shake it up and hear the sound of "whoosh", it proves that the product is insufficient or volatile, it is not recommended to buy.

3. Contents.

Before use, observe the contents of the paint, the surface must not have crust, the paint liquid is transparent, uniform, and free of impurities.

4. Constructability.

The paint quality is good, the ratio is strictly in accordance with the requirements of the instructions, the feel is delicate, the gloss is uniform, and the color is uniform, and it has a good construction tolerance.

That's a very good question, as far as I know, I think it should be like this, and now it's all outsourcing companies that paint walls.

They send people, and they will carry out the work with paint, so don't prepare anything yourself, everything is prepared by the master, just negotiate it yourself.

The paint for painting the wall can only be bought by yourself, and this master is only responsible for the construction, and the raw materials must be prepared by yourself.

Painting the wall is a contractor, that is, the master buys, and the contractor cleans, that is, you buy it yourself, depending on the nature of your contractor.

It depends on whether it's half a pack or a full pack.

1. Paint can be painted on the wall.

2. The paint can not be directly brushed on the wall, when we use paint to paint the wall, we must do all the steps before painting the wall.

3. Before painting the wall, you must first use cement to lay the foundation, before you need to fill the putty, local dirty putty leveling, and then apply a layer of solid primer after the putty is smoothed for the second time, and then brush a layer of paint.

4. After adding another layer of putty, after continuing to grind, we will brush the paint for the second time, and then we can start to paint.

4. After adding another layer of putty, we will continue to grind the smooth worm stove, and then we will brush the paint for the second time, and then we can start to brush the paint.

The above figure is the number of layers of wall treatment, from the outside to the inside, they are the paint layer, the primer layer, the wall lining leveling layer, the grid cloth layer, the gypsum leveling layer, and the wall solid layer.

As you can see from the picture above, as long as your basic treatment is very smooth, the difference between painting and painting effect is not obvious, but if you choose materials and later maintenance, the following are the specific differences:

1. Painting: advantages: fast construction, good flatness, no poor texture, suitable for latex paint, smooth coating surface, high hardness, good cleanliness and easy cleaning;

Disadvantages: high cost of paint loss, troublesome maintenance in the later stage, and easy color difference after maintenance.

2. Paint: Advantages: soft color, good air permeability of coating, low cost, rolling texture and pattern on the paint surface, and easy maintenance.

Disadvantages: the process requirements for workers are relatively slow, the effect of large-surface roller coating is different from the whiskers in the yin corner and the light trough, there are texture differences, and the loss of paint is relatively large, which is not particularly affordable.

There are pros and cons to both modes of operation, but it is relatively better to spray.

The construction process of latex paint brushing is relatively simple, we can use a brush and roller to dip the latex paint and paint it on the wall;

The construction of spraying latex paint is much more complicated, which is through a booster pump, generally a plunger pump, to pressurize the latex paint to obtain high pressure and release pressure from a special nozzle, so that the latex paint is dispersed and atomized and applied to the wall at high speed.

The advantage of latex paint brushing is that the construction is convenient, the wall surface brushed out is very textured, and it is more convenient to maintain, and its disadvantage is that the flatness of the brushed wall is not the smoothness of spraying;

The advantage of spraying latex paint is that the construction is complex, and the wall surface sprayed out is more flat and shiny, and its disadvantage is that the requirements for the workers and masters are higher.

The construction efficiency of spraying latex paint is high, which is about 10 times that of brushing; The painted wall is very smooth, brush-free, and the coating lasts longer. High-pressure airless spraying, which uses high-pressure jet atomization, so that the paint particles can obtain strong kinetic energy to penetrate into the pores of the wall, so that the paint film and the wall form a mechanical occlusion, enhance the adhesion of the coating, and prolong the life.

Answer the latex paint spraying method, it requires a relatively high technical level and equipment, so the cost is high, and some environmental restrictions are not conducive to spraying construction, which is easy to cause decoration damage and is more inconvenient. The roller coating method, because it is manually operated, can save costs, but it needs to be combined with the craftsmanship of workers, so only a very professional construction worker is required.

Then compared with the spraying method and the roller brush method, the spraying method is sprayed out by the spray gun during construction, and it is controlled by the machine, so the paint film will be relatively thin, and several painting processes are required to achieve better results, so it is more expensive to paint. Moreover, it is more troublesome to maintain in the later stage, if there is a local need for maintenance, the painter basically will not bring a bulky spraying machine to repair, and the repair area is small and not suitable for spraying with a machine, so it can only be repaired by the roller coating method, but it is easy to cause a large color difference, which is very ugly.

Each has its own benefits, spraying is more uniform, but the later repair is very troublesome, the construction personnel can no longer drag the spray gun to repair, and the repair of a small area will be easy to appear color difference. As long as you polish it with sandpaper in the damaged area, and then use a brush to paint it, it is not easy to see the difference. However, the disadvantage of brushing is that it is slow and easy to leave traces of bristles.

Chenguang interior wall latex paint is water-based and environmentally friendly, moisture-proof and mildew-proof, dirt-resistant and stain-resistant. Generally, the home decoration is painted with roller, which is faster than brushing, and the traces left by the roller are not obvious; Compared with spraying, it is lighter than dragging a large machine back and forth.
