Why can transparent epoxy floor paint be torn off like paper?

Causes of peeling of epoxy floor paint:

1. Poor quality of epoxy resin material will lead to undurable ground, peeling, delamination, discoloration, cracking, etc.;

2. Failure to construct in strict accordance with standards and cutting corners will lead to undurable ground, peeling, delamination, cracking, etc.;

3. The ground is not made of moisture-proof layer, which will lead to epoxy floor bubbling and delamination;

4. If the ground is not cleaned, it will lead to delamination and peeling of the epoxy floor;

5. If the amount of epoxy material is too small, it will lead to the ground being exposed;

6. If the ground shrinkage joints are not repaired, it will lead to ground cracks;

7. Epoxy flooring will cause fading under the irradiation of the sun;

8. Construction in bad weather or environment will also lead to quality problems.

The 1:1 material is primed with a hardener and is transparent. 1:1 epoxy floor paint, actually epoxy polyurethane. The taste is relatively strong. In addition, because it needs to be covered with an extra layer than epoxy resin floor paint, it is now slowly no longer needed.

The primer has two functions, one is the sealing effect, the other is to connect the ground and the floor paint to better cooperate, generally there is no color of the transparent liquid, the top coat is generally made of more colorful, and the surface effect can be made in various styles.

Epoxy resin floor paint primer main uses:

1. Sealing and barrier function: the main functions of the sealing effect are reflected in: anti-pan alkalinization, anti-salting-out property, balanced and uniform water absorption of the foundation ground, and ensuring the uniformity of color and gloss of color paint or varnish after construction.

2. Enhance and strengthen the foundation ground: For the loose foundation ground and the old ground, after the grinding and vacing treatment, the primer is painted, and the epoxy resin primer has good penetration into concrete and terrazzo, etc., reinforcing the base layer and providing the adhesion of epoxy resin floor paint, so as to ensure the service life.

3. Improve the adhesion of the topcoat: balance the absorption degree of the base paint, so as to ensure the uniformity of the gloss and color of the topcoat, improve the decorative effect of the topcoat and prolong the service life of the topcoat.

Epoxy resin floor coating bottom, middle and top coat are indispensable in the project, each has its own duties, plays different roles and functions, so that the performance of the entire epoxy floor engineering can be brought into full play, whether it is from the performance, or aesthetics, economic aspects can meet the needs of customers.

The primer is not painted, or some of the paint is elastic, and you need to tear the color separation paper immediately after doing it.

Hello, I am helping you to inquire about the relevant information, give me a little time, and I will solve your doubts soon

Regarding the various problems of the wall, in fact, the causes are more complex, and it is not necessary that one symptom is one cause. It's like seeing a doctor, like a cough doesn't have to be a cold. Specific problems should be checked by experienced masters on site.

If the wall paint film is torn off like paper, it does not mean that the paint is not good, on the contrary, the wall paint that can be connected into a film has a higher emulsion content and better quality of the paint.

Regarding the various problems of the wall, in fact, the causes are more complex, and it is not necessary that one symptom is one cause. It's like seeing a doctor, like a cough doesn't have to be a cold. Specific problems should be checked by experienced masters on site.

If the wall paint film is torn off like paper, it does not mean that the paint is not good, on the contrary, the wall paint that can be connected into a film has a higher emulsion content and better quality of the paint.

If there is no external injury to the wall and the paint surface falls off in pieces, there are several possible reasons: 1. The quality and viscosity of the putty are not good; 2. The primer is useless or the quality of the primer is not good; 3. Apply primer if the putty is not dry, and apply the second time if the paint is not dry. If you want to avoid some common latex paint problems on the wall, you should avoid some common mistakes during construction, such as:

Don't use putty that is too bad; Each putty and latex paint should wait until the previous one is completely dry before applying it a second time; Latex paint can not be mixed with too much water (especially when the material package is out, the decoration company will try to save as much as possible); Use primer, don't paint directly, etc.

Do you have any other questions? The order ends automatically after 24 hours, and if I'm helpful to you, I look forward to your like.

Check it first, start 2 times putty, whether there is latex paint, how much to putty, generally 12-15 packs of putty plus 1 barrel of Longma latex paint, which is the key to ensuring the strength and toughness of the bottom putty, especially the poor quality putty.

If it is not easy to figure out, then use a gray shovel to shovel it to see how the strength of the putty is, if it is very poor, you can easily shovel it to the mortar surface without drenching water, indicating that the bottom putty is indeed not enough, too loose, poor strength, and should be shoveled off. Shoveling putty generally does not damage the line pipe.

If only the last layer is easy to shovel (because the last layer of putty is always only water, easy to polish, the strength should be poor, and it should be soft), then shovel off the last layer of putty, sweep away the floating ash on the wall, re-batch the better putty, and do the primer topcoat at the back.

Generally, it is not autumn and winter, it is recommended that the putty is finished, left for a week to dry thoroughly, and then painted. Wait at least 24 hours after each brush before you can move on to the next one. If there is still moisture in the wall, the surface of the paint film dries first, and the moisture will be difficult to come out, and it will be heated into water vapor, and the paint film will be easy to detach.

An introduction to epoxy resin floor paint.

Epoxy floor paint is a floor paint produced using a mixture of epoxy resin and hardener.

Epoxy resin floor paint has the characteristics of strong acid and alkali resistance, wear resistance, pressure resistance, impact resistance, mildew resistance, waterproof, dustproof, anti-slip, anti-static, electromagnetic wave and so on, with bright and diverse colors and easy cleaning. It adopts a one-time coating process, no matter how large the area, there is no connecting joint, and it is also a dust-free material, with the characteristics of beam width, strong adhesion, wear resistance, and strong hardness.

Epoxy resin floor paint is widely used in electronics factories, machinery manufacturing plants, hardware factories, pharmaceutical factories, automobile factories, hospitals, aviation, aerospace bases, laboratories, offices, supermarkets, paper mills, chemical plants, plastic processing plants, textile factories, tobacco factories, candy factories, wineries, beverage factories, meat processing plants, parking lots and other surface coatings. At present, it has been accepted and used by many domestic manufacturers.

Pay attention to things quietly: avoid construction under low temperature and high humidity conditions; After the two-component material is mixed, it should be applied in a short time; After the coating is completed, it should be fully passed before it can be put into use; According to the flatness of the substrate and the requirements of the use of rubber and brightness, the coating thickness is determined. The worse the flatness of the ground, the thicker the coating system is used, the greater the coating load, the thicker the coating should be, if the coating is too thin, it is easy to be damaged during use, such as the ground on the first floor also needs to do a good job of waterproof treatment.

The surface is smooth and flat, and the gloss is semi-glossy and matte, and a variety of colors are available; **Reasonable: Solvent-free, solvent-free epoxy floor coatings at the same price.

Epoxy resin is a general term for organic polymer compounds containing two or more epoxy groups in the molecule, and their relative molecular weight is not very high except for a few exceptions. The molecular structure of epoxy resin is characterized by the presence of active epoxy groups in the molecular chain, which can be located at the end, middle or in a cyclic structure of the molecular chain. Because the molecular structure contains active epoxy groups, they can cross-link with various types of curing agents to form insoluble, non-meltable polymers with a three-way network structure.

Epoxy resin is a component of epoxy floor paint, and the two belong to the inclusion relationship.

That's because a lot of solvent is added to dilute it, and if there is no miscalculation, it should smell very strong. If you have enough money, you will add an active diluent, and the smell will be much smaller, but the cost is huge.

The chemical reaction is viscous when mixed together. After a long time, it was dry. Got it?

If it is abnormally thin, it means that your paint has been in the water (thinner) for many days, which means that it is fake, because the thinner is always much cheaper than the paint.

It may be that the thinner has been added too much...
