Generally, latex paint does not brush the primer, can I brush the topcoat twice directly?

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. 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.

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.

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.

<> "No, if you brush it only once, it will affect the use time of the paint, and it may also cause peeling and peeling. In general, we apply primer once, topcoat twice, and after each layer of paint is dry, we need to sandpaper it. In addition, the brushing of latex paint can only be brushed more, try not to brush less in order to save money and crack it, although on the surface, only one brush of topcoat can shorten the decoration period.

However, the painting results are not very good, which means that they will need to be repainted later, and the budget is often higher than before.

What do you need to pay attention to in the construction of latex paint.

1. The wall must be dry. The new house needs to be naturally dried for more than 10 days after treatment, while the concrete wall needs to be naturally dried for more than 20 days, and the moisture content of the wall is lower. Paint should be stored in a cool, dry place above 0.

2. Refer to the relevant product manuals as much as possible for adding water. Too much water will reduce the gloss, film-forming and durability of the paint. The construction must be stopped if the temperature is lower than 5, the construction must be stopped if the air humidity is too high (higher than 85%), and the construction is strictly prohibited below 0.

3. The construction of the exterior wall should be stopped in rainy days. If it rains within 12 hours after the end of construction, it can be blocked to prevent rainwater from washing the cladding.

4. 107 glue is needed for fan ash. It is very likely that the wall will be powdered and moldy quickly, and the paint will peel off, so it is best to add some preservatives. Fan ash topcoat can only be applied after the fan ash surface has dried.

5. Unused paint should be sealed to prevent drying and waste, and workers should rinse it with water immediately after discharge.

Summary. Hello, there is no need to brush the primer after the latex paint is brushed, but the primer can be brushed before the latex paint, and the benefits are, 1. The sealing effect, the primer can effectively seal the base layer and make the wall base layer more firm. This kind of sealing effect can effectively alleviate the situation of "pan alkali" on the wall.

2.Filling, the primer also has the effect of filling the wall, which can make up for the fine cracks and improve the flatness of the wall. 3.

Cost-saving, primer is cheaper than topcoat, so applying primer before topcoat can save decoration costs.

I forgot to brush the primer, I brushed the latex paint for 10 years in the house, the new latex paint was more than 3 months, the wall was no problem, there were cracks before the repair was completed, and now I want to brush the latex paint once, and I can brush the latex paint after the primer.

Can you brush the latex paint after brushing the primer on the original latex paint, or brush the latex paint directly?

Hello. Apply latex paint directly.

Find a worker, repair it partially, and brush it as a whole.

Okay thank you, what to do with the amount of water in latex paint, hello, 5 to 1. Generally, the proportion of latex paint with water determines the quality of the wall painting effect, if the water is not suitable, it will cause the wall to crack and fall off in the later stage, if the water is too much, it will cause the paint to be too thin, and it will also affect the covering effect of latex paint, and it will not cover the cracks and protect the wall.

Dear, hello, latex paint can be brushed twice a day, under normal circumstances, latex paint needs to wait at least 4-6 hours before the next brush to ensure that the last paint has dried. Therefore, it is possible to apply latex paint twice a day, but the following recommendations need to be followed:1

Make sure the first brush is completely dry, usually 4-6 hours or more, depending on factors such as ambient temperature and humidity. 2.After the first coat has dried, a second coat of paint can be applied, but you need to make sure that the first coat of paint is not peeling, cracking or blistering.

3.After the second coat of brushing, wait at least 24 hours to ensure that the paint is completely dry and the best results are achieved. It should be noted that the time interval between applying latex paint depends not only on the drying time of the paint, but also on the ambient temperature, humidity and the state of the paint surface, so it needs to be adjusted according to the actual situation.

At the same time, when brushing latex paint, it is necessary to pay attention to good ventilation, avoid inhaling harmful gases, and use protective measures, such as wearing masks and gloves.
