Why do painters recommend not applying primer? Is it unnecessary or just to save trouble?

The primer is the first layer of paint on the wall, and the topcoat is the last layer on the wall. The role of primer has also been described in detail above. Topcoats are mainly used for decoration and protection.

In the case that some owners in the north did not brush the primer, the ingots did not expose the problem, mainly because the north has less rain and a dry climate, and the probability of Fan Jian's moldy ingots is very low, and the foundation of the ingots, the uneven surface of the blank, and the coating of a layer of liquid foundation, immediately has the ability to repair the bridge, and the primer also has such a magical effect.

The primer consists of four parts: resin, filler, solvent and auxiliary. The difference between topcoat and primer is that the former has little or no filler added. Primers and topcoats are different.

Primer is a layer of the coating system that is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, provide anti-corrosion functions, etc. At the same time, it can ensure the uniform absorption of the topcoat and make the coating system work. If the topcoat is ***, you can do without the primer, which is not right, because the role of the topcoat and the primer is different, the topcoat pays more attention to the final decoration and appearance effect, while the primer plays the role of sealing the substrate and connecting the topcoat.

You can't directly brush the topcoat twice without priming. This is because both the primer and the topcoat are dry glue paints and usually need to be used together. The painter who came down told me"We don't need primer now, directly brush the topcoat twice, the effect is no, the outside construction site does this, mainly to help you save money, rest assured that there will be no problem, if it causes problems, you also come to us to repair, you say,"Because the primer is a type that can improve the adsorption of the topcoat; Moreover, the primer also has the functions of anti-corrosion and alkali resistance, so the primer should be brushed.

Under the action of the primer, it has the effect of moisture-proof and alkali-proof, improves the hiding power, and enhances the adhesion of the topcoat, so that the topcoat is more plump and has better performance in all aspects. That is to say, the standard of painting the wall, one bottom and two sides, is still necessary, and if something goes wrong, the painter will not be responsible. Here's the thing, it's very simple, it's to ask the decoration company to paint me with primer, because there is no primer in the list, so I need to pay.

Maybe in the later stage of the renovation, the money has been a little numb, and the additional project confirmation letter has been signed.

Brush the topcoat twice without priming it mainly to save time, many people think that the primer can be brushed without painting, in fact, as long as there is putty, you must brush the primer.

Because brushing the base paint oil and then painting the top paint will have an impact on the future repair, so it is not necessary.

There are several main reasons why painters recommend not painting primer:1The cost of primer can be eliminated.

Primers need to be purchased and applied separately and are also more expensive, which can be saved if you don't paint them. This is also a major factor for many owners and workers to consider. 2.

Adhesion between the paint and primer layers may be insufficient. If the adhesion between the primer and the paint is insufficient, it is easy to crack and fall off, which will affect the appearance and service life of the paint. Without priming, the paint is in direct contact with the substrate for better adhesion.

3.Primers can affect the breathability of paint. Some primers will weaken the air permeability and moisture resistance between the paint and the substrate, resulting in the paint being susceptible to moisture deterioration in a high humidity environment.

If you don't brush the primer, you can maximize the breathability and moisture-proof effect of the paint. 4.The paint itself has a certain anti-corrosion and isolation effect.

High-quality paints, especially some anti-corrosion models, have good anti-corrosion and isolation effects in themselves, and it is not necessary to brush the primer as the bottom layer for isolation. This can get the job done directly with high-performance paints. 5.

The construction process is simpler without priming. If there is no need to brush the primer, the construction process of the primer can be omitted, which greatly simplifies the construction process and reduces the difficulty of construction, which is also the consideration that the construction personnel tend to omit the primer. Therefore, considering factors such as cost, performance, and difficulty of construction, the paint union recommends that the scheme of not painting primer be selected in some projects.

However, if the paint performance requirements are high, or the substrate condition is poor, then brushing the primer is still a better choice to achieve better isolation and protection.

Hello, dear . Painters recommend not applying primer to ensure a good topcoat result. Because the primer is made of a thicker material, it has strong adhesion, if you accidentally brush too much or unevenly, it will affect the quality of the topcoat, and there will be problems such as blistering, peeling, and falling sails.

The primer may also react chemically with the topcoat, causing unwanted negative effects. If the paint properties of the primer and the topcoat do not match or cannot be well matched, it is easy to cause different degrees of air holes and cracking, which affects the surface decoration effect. If there are some special circumstances, the primer is still needed.

But before any painting task, it's best to consult with a professional worker and let them give advice based on the situation<>

Hello, glad to answer for you, the reason why painters do not recommend applying primer first when applying paint is that the use of primer may affect the final paint result. Primers are usually used to apply to surfaces in order to increase adhesion and reduce the absorption between paint and surface. However, it does not have weather resistance and aesthetic properties, and cannot effectively protect the surface.

If you apply paint directly to the primer, it can cause the following problems:1The absorbent nature of the primer can make the paint thinner and can lead to uneven color.

2.The paint doesn't adhere well to the base paint because the paint doesn't have a dry surface to stick to. 3.

If there is a problem with the paint, such as peeling, then the primer will also lose its protective effect. So, while primer can increase the adhesion of the surface, when you want to paint a surface, we recommend first making sure that the surface is clean and free of defects, if there are defects, you should fix them first, and finally apply the paint carefully to get the best paint result. The above is my reply, I hope it can help you!

Hello dear, happy to answer for you. The main reasons why painters recommend not painting primer may be the following: time and cost:

The primer takes a certain amount of time to dry before the topcoat can be applied, which requires additional time and cost. At the same time, the primer also needs to be purchased and handled separately, which increases the cost and difficulty of the work. Simplify your work:

Priming can indeed increase the adhesion and smoothness of the film during construction, but if the surface is in good condition, the paint finish is not too bad, and the use of high-quality exterior paint, the primer may be dispensed with. Environmental protection: The primer contains a certain chemical composition, so the use of the primer may cause some pollution to the environment.

There are new exterior paints that already have excellent adhesion and durability and can be used without primers. The above are some possible reasons, it should be noted that the situation will vary depending on the region, working environment, travel and other factors, and the construction should be carried out according to the specific situation. During the construction process, it is recommended to work with a professional painter to decide whether a primer is needed according to the actual situation.

Hello dear, the reason why the painter recommends not to brush the primer is that the primer belongs to a special coating, and its main role is to enhance the adhesion and durability of the coating. Primers generally use a separate product, which is different from the primer part of the paint. If a primer is applied to the paint, an interface between the primer and the paint is formed, which can affect the adhesion and durability of the coating, and even cause the coating to peel off or crack.

In addition, primers and coatings are used in different ways and requirements. The construction of the primer needs to consider its own performance characteristics, such as drying time, selection of thinner, etc., while the construction of the coating needs to consider its own performance characteristics, such as coating thickness, drying between the two parts, etc. If the primer and paint are mixed, it may affect the quality and effectiveness of the coating.

Therefore, the painter recommends not to brush the primer to accompany the paint, but to choose a special primer product and apply it in accordance with its use requirements to ensure the quality and effect of the coating.

Good afternoon, dear, the reason why painters do not recommend applying primers is because primers can sometimes be counterproductive in certain situations. Primer is a pigment applied to a surface, mainly used to fill uneven parts of the surface and improve surface adhesion. The primer usually needs to be topped with a topcoat to achieve the final finish.

However, in some cases, brushing the primer can cause the following problems:1Increase the painting time and cost of Qing Bu Xun:

Priming requires additional time and cost, which adds time and cost to the overall painting process. 2.Increase the thickness of the paint:

The primer increases the thickness of the coating, which can affect the gloss and texture of the surface. 3.Produce color deviation:

The color of the primer and topcoat can not match, which can lead to color deviations. 4.Flakiness, cracking and other problems:

If the adhesion of the primer and topcoat is insufficient, problems such as peeling and cracking may occur, which may affect the coating effect. Therefore, the painter recommends that during the actual construction process, decide whether the primer needs to be painted on a case-by-case basis to ensure the best coating effect.

Dear, because the paint is very thick when painting, it is about two millimeters to three millimeters for a long time, and there will be no paint loss, so there is no need to brush the primer in general. On the one hand, it has an impact on its sealing effect, and on the other hand, it is difficult to guess that the amount of construction on both sides is more when brushing, and it is also more labor-intensive for painters. It is better to stick to the wall cloth or brush latex paint from the following two perspectives:

1. Aesthetics: From the perspective of aesthetics, the wall cloth is slightly better. It is a material that uses cotton cloth as the base cloth and applies printing or embossing on the base cloth, so it has a strong three-dimensional effect, and can create an artistic atmosphere in the bedroom, which is suitable for various styles.

Whereas, latex paint has a single color, and the most common is white. 2. Practicality: From the perspective of practicality, wallcovering and latex paint have their own advantages.

If it is a professional master to lay the wall covering, it is no problem to use it for 10-15 years, even in the humid south, the life span can reach 10 years. However, excessive humidity is prone to mold and produces an annoying odor. The practicality of latex paint is very strong, and even if it is stained in the later stage, it can be wiped with a damp rag.

In the event of a major stain, simply apply another layer to the surface.
