Some people say that you can paint the wall without a primer and use a topcoat both times, is that t

Wrong. The primer has alkali resistance and better adhesion than the topcoat, there is a lot of dust after beating the sand, the primer brush is more guaranteed for the quality for the first time, and the general topcoat has better stain resistance, and the adhesion is relatively poor.

The current construction requirements are one bottom and two sides, and only brushing the topcoat is a cut corner, and the sealing effect of the primer is usually not possessed by the topcoat.

It can be, but the topcoat is high, you don't want to do it, and the topcoat is relatively smooth, and the adhesion between the wall substrate may be lower than that of the primer, and the effect of the second topcoat is not as good as the bottom surface in terms of appearance and long-term effect.

Be sure to paint low, not just for money.

The wall is painted with latex paint, and it is OK to brush 1 or 2 deviations directly.

Well, in fact, primer usually refers to the paint with poor quality, which does not affect the overall effect at the beginning, and is economical and affordable.

Of course, there are a few exceptions, such as real stone paint or others, such a project values the degree of practicality, from the aesthetic layer is a little not very good, from a long point of view.

Yes! If your walls are already sanded, two coats of topcoat will do. Under normal circumstances, the paint will be left, you don't want the primer and topcoat to be left, right? And if you repair it later, only use the top coat.

Don't try to save trouble, it is best to brush the primer, the topcoat has a matching primer, the bottom layer has good oxidation and saltiness resistance after the primer is brushed, and the gloss of the entire wall will be more uniform after brushing the primer, and the visual effect will be better.

You can't apply topcoat twice without primer

In a paint system, the primer is the first layer to be painted. Its main function is to make the paint surface flat, thereby supporting the paint surface, making the paint surface look fuller and reducing the cost of decoration.

At the same time, it spikes energy savings. The topcoat is the last "gatekeeper" of the entire paint system. It reflects the gloss of the entire lacquer surface.

Hand feel, scratch resistance and other characteristics, so the quality of the topcoat directly determines the quality of the entire paint film.

The consequences of not priming it.

1. If you don't apply primer, you won't be able to seal the wall. Since the wall is alkaline, soaking in moisture, water, etc., will produce alkaline flowers. If the primer is not applied, the latex paint will be applied.

Cause damage. 2. If the primer is not applied, the adhesion of latex paint to the wall is very low. Applying latex paint after priming will enhance his adhesion.

3. Generally, the rough wall is uneven. Primers can fill these uneven parts of the wall, making latex paint easier to color.

Latex paint. It is not possible to apply the topcoat twice without priming. In the paint system, the primer is the first layer to be brushed, and its main function is to make the paint surface smooth, so as to support the top coat, make the paint surface look fuller, and reduce the cost of decoration.

At the same time, it also saves energy, and the topcoat is the last "gatekeeper" in the entire paint system, which can reflect the gloss, feel, scratch resistance and other characteristics of the entire paint surface, so the quality of the topcoat directly determines the quality of the whole paint film.

Can the surface be brushed twice without primer? Self-provided: Wall brush topcoat, literally understand, should be brush the wall solid, or scrape flat putty powder, can also understand that scrape twice water-resistant putty powder, brush twice wall odorless paint, topcoat, paint twice is not allowed.

The wall decoration of the new house is the most indoor space in the overall total area, and there are many special attention to the wall decoration, which is paid attention to, and the wall decoration is carried out in accordance with the order of steps, which can ensure that the resistance period and <>

Otherwise, it is very easy to have general product quality problems. Small defects in the wall, or interior decoration not in accordance with the order of steps, shoddy condition, is not allowed, no matter which procedure, in accordance with the relevant standards of engineering construction. Wall decoration two, wall decoration with several types of raw materials, each raw material has a different role, according to the questioner clearly put forward the problem, the front of the brush several times of topcoat, and then is to do the lowest layer of the wall architectural coating, on the wall to paint the wall solid, wall fixing glue, 108 glue, waterproof putty, upgrading goods, mainly used in the maintenance of walls, <>

Producing protective film on the wall, there is no doubt that the wall is not plastered with wall solid, and this kind of construction method is not standardized. Generally, if you want to achieve the effect of public standard home decoration, you must build at least one topcoat and then paint twice. If you use one less topcoat, you need to use one coat more often, i.e. three times all paint.

In terms of price, paint is much more expensive than topcoat. The multi-functionality of primer and topcoat has its own emphasis, and the actual effect of topcoat engineering construction is not smooth, which can improve the adhesion of paint;

The topcoat can penetrate into the interior wall putty powder layer to smooth and close the putty powder, so that the wall is not easy to alkali, canIt is reasonable to deal with the problems of wall paint blocking, falling off, and mildew points. After the painting operation, the coating film is fine and smooth, although the decorative art is strong, but there is no smoothing effect. Usually, the project has to be built many times, and a lot of raw materials are consumed before the surface layer can achieve a certain decorative effect.

No, there will be some cracking, and the color is not particularly good-looking.

I think of course it is possible to do without the primer, but also to apply the topcoat directly.

In the process before the decoration, it is best to brush the primer, which will be better or use putty. Then place the latex paint, which is better.

In terms of surface effect, it is possible to directly brush the topcoat on both sides; However, from a quality point of view, there is a great hidden danger in the practice of directly brushing both sides of the topcoat without primer.

Considering economic factors, the cost of some primers is higher than the cost of topcoat, and the design requirements of the house may not be too high. For this reason, they are not willing to spend more on this primer. This idea is wrong, no matter how good the topcoat is, it cannot replace the primer.

Because the primer mainly plays the functions of sealing, alkali resistance, enhancing the adhesion of the topcoat, and saving a certain amount of topcoat, if the primer is not made, it is easy to wrinkle and bloom after a period of time, and may cause the paint film to dry too quickly and cause topcoat cracking and waste of topcoat.

Latex paint is not brushed with primer, and it is not possible to brush the topcoat directly twice. The primer is the first layer of the paint system, which is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, provide anti-corrosion function, etc., and at the same time can ensure the uniform absorption of the topcoat, so that the paint system can play its best effect. Topcoat *** can do without primer, this statement is not correct, because the function of topcoat and primer is different, topcoat is more focused on the final decoration and apparent effect, while primer focuses on improving adhesion, anti-corrosion function, alkali resistance, etc.

That's what the primer does:

1. Sealing: Latex paint primer can play a sealing role and alleviate the alkali on the wall.

2. Adhesion: The emulsion content in the primer is high and the adhesion is strong. It can improve the adhesion between the latex paint film and the wall.

Applying a layer of sealing primer before applying the topcoat can not only save the decoration cost, but also have the advantage of getting twice the result with half the effort in the long run and the decorative effect. At the same time, the good adhesion of the primer makes the wall surface smoother, making the topcoat easier to apply and reducing the amount of topcoat used. In this way, the wall not only avoids paint sickness, but also helps to maintain the painting effect for a longer time.

It is necessary to brush the primer before brushing the latex paint, and you cannot brush the latex paint twice. There are several reasons for this:

1. If you don't brush the primer, it can't close the wall. Because the wall is alkaline, alkaline flowers are produced after being soaked in moisture and water, and if the primer is not brushed, it will cause damage to the latex paint.

2. If the primer is not brushed, the adhesion of latex paint on the wall is very low. Applying the primer and then the latex paint will enhance his adhesion.

3. The general rough wall uneven and pothole-filled primer can fill these uneven parts of the wall, which is easier when brushing latex paint.

To sum up, before painting latex paint, you need to brush the primer before brushing the latex paint. It can extend the service life of latex paint.

Some people generally take into account economic factors, and some primer costs are higher than the cost of topcoat, because they feel that their requirements are not too high, and they think that they can save and save, and the effect of directly brushing the topcoat twice can also be the same For this reason, they are generally not willing to spend more on this primer This idea is wrong, because no matter how good the topcoat is, it cannot replace the primer, because the primer mainly plays a role in sealing the alkali resistance to enhance the adhesion of the topcoat and save a certain amount of topcoat and other functions, if you do not do primer, After a period of time, it is easy to wrinkle and bloom the paint film, and may cause the paint film to dry too quickly and cause topcoat cracking and waste of topcoat; Generally, cement walls are also easy to return to alkali, strong alkalinity can lead to the chemical degradation of resin in the coating, accelerate the aging process of the coating film, reduce the service life of the coating, and now the decoration uses a lot of water-resistant putty and wall lining is also alkaline, the construction process of primer can play a significant role in the protection of the topcoat. In particular, the alkali-resistant primer has a strong penetrating effect, which can effectively seal the capillary pores of the substrate, so as to avoid the alkali and water-soluble salts in the substrate from seeping out of the surface with the migration of water through capillary action, and at the same time prevent the frosting and alkalizing, and protect the topcoat from chemical attack, and at the same time can avoid the excessive absorption of the porous base paint, improve the decorative effect of the topcoat, and save the amount of topcoat. There are many people who think that with cheap paint brushes below, good paint brushes outside, so as to save costs, such ideas are also very unscientific, and it is easy to have problems, and the general decoration company does more It is recommended that the primer must be done in the construction process, and it is necessary to paint evenly, so that it is possible to effectively close the wall, and it is not easy to decorate it once, and there is no need to save this expense, and ignore the future decoration effect Besides, the cost of wall paint accounts for a very small proportion in the entire decoration process, only That's it, but the decorative effect shown accounts for the entire decoration area At most Based on the above reasons, it is recommended to brush the primer!!

Yes, but the overall effect will be better after using the primer.

Is it really good to decorate with only a layer of primer instead of topcoat in order to save money? In the decoration process, wall painting is an indispensable process. Primer and topcoat are both wall paints, what exactly is the difference between the two?

I believe that it is also a question for many owners, and now the decoration sister will explain the difference between the two in detail.

Is it okay to brush the topcoat twice without priming?

Some people generally take into account economic factors, because they feel that their requirements are not too high, and they think that they can save and save, and the effect of directly brushing the topcoat twice can be the same, based on this reason, they are generally unwilling to spend more on this primer.

1. This idea is wrong, because no matter how good the topcoat is, it cannot replace the primer, because the primer mainly plays the functions of sealing, alkali resistance, enhancing the adhesion of the topcoat and saving a certain amount of topcoat.

2. The general cement wall is also easy to return to alkali, strong alkalinity can lead to the chemical degradation of the resin in the coating, accelerate the aging process of the coating film, reduce the service life of the coating, and now a lot of water-resistant putty and wall lining are also alkaline in the decoration, and the primer can play an obvious protective role in the topcoat during the construction process. In particular, the alkali-resistant primer has a strong penetrating effect, which can effectively seal the capillary pores of the substrate, so as to avoid the alkali and water-soluble salts in the substrate from seeping out of the surface with the migration of water through capillary action, and at the same time prevent the frosting and alkalizing, and protect the topcoat from chemical attack, and at the same time can avoid the excessive absorption of the porous base paint, improve the decorative effect of the topcoat, and save the amount of topcoat.

3. It is recommended that the primer must be done in the construction process, and it must be evenly painted, so that it is possible to effectively close the wall, and it is not easy to decorate it once, and there is no need to ignore the future decoration effect in order to save this expense. In addition, if you do not brush the primer to close the base layer, it is very troublesome to renovate the wall in the later stage, and in the end you still need to brush the primer, so that the cost is even more, and it also consumes people's energy, time, etc., and the cost is higher in general. Therefore, it is not advisable to brush the topcoat twice without brushing the primer, and you must brush the primer and choose a relatively good quality primer, so as to really solve the problem of the wall at the source.

New house decoration, at least a few materials to use, the role of each material is not the same, the wall decoration is more complex, especially prone to small problems, in the decoration process, according to the construction process, to buy the right materials, in order to ensure the quality of decoration. The questioner asked the question: can I not paint the primer, but can I paint two topcoats?

The following is a detailed analysis and answer for readers' reference. The wall decoration of the new house is also the largest space in the overall area, and the wall decoration has a lot of exquisiteness, and there are a lot of exquisiteness, and the wall decoration in accordance with the process order can ensure the durability of one year, otherwise it is easy to have common quality problems.

There are small flaws in Metepu, or there is no decoration in the order of the process, there is a situation of cutting corners, it is absolutely not possible, no matter which plan, the construction according to the relevant standards can be. According to the questioner, brush the primer twice in front, and then do the matep primer, fix the metep to paint the wall, metep fixing glue, 108 glue, interface agent and other updated products, mainly used to protect metep, form a protective film on metep, one thing is certain, metep will not paint the wall solid, this construction method is not standardized.

A process of METEP decoration, as the questioner said, do not brush METEP primer, like this case, it is very rare, this is decoration, there is not much difference, vulgar to say, decoration METEP is less, brushing primer is a must, METEP is the first in decoration, it is solid, applied to the wall of METEP fixing glue, barrel emulsion, has a certain penetration function, has a good wettability for gap treatment.

Wall fixing glue, can better fill the gaps of wall cracks, avoid small decoration, new cracks in the cracks, wall fixing glue brush three times, paint once the wall is firm, it has a process of filling and penetration, dry you can see, wall decoration base, at least three times to paint on the line. For example, gypsum powder should also be wiped smooth to increase the cost of decoration, that is, gypsum powder should be wiped smooth on the ground, even if it is smooth, there is no problem.
