Why does the floor paint come off after 12 hours of brushing? What is the remedy

If the floor paint falls off after 12 hours, it is likely that the ground is not well treated, and the base surface is not clean, which affects the adhesion of the primer, or it is possible that the paint quality is not good and the adhesion is not good. If the reason for the rejection of product quality is the ground treatment, such as the tile floor, if the paint is not sanded and directly rolled, it will also fall off, because it is too slippery. For the problem of falling off, see whether the scope of falling off is large, if it is recommended to renovate, if it is not large, you can use the method of repair.

1. Spraying and repairing method.

If you see that the damage to the floor paint is not too serious, you can better help the damaged ground to repair it through spraying and repairing.

2. FRP construction method.

The scope of application of floor paint is very wide, and the method of purchasing floor paint in different places is different, and the scope of application is in the long cracks such as expansion joints in building structures.

3. Point compensation method.

In life, the point repair method is more common, and it is also more in line with the small part of the floor paint scratch, the point repair method construction process is simple, easy to master, and the amount of raw materials is small.

4. Overall covering method.

For some factories and garages that are used, it is okay to choose the covering method, because this will not affect the overall aesthetics of the floor paint, and the covering is also very beautiful and beautiful, and the cost will not be very high.

If it is the whole delamination, it is likely that the base surface is not well treated, such as the base surface is wet, the base surface is uneven, the base surface strength is not high, etc., it is recommended to shovel off the coating, reprocess the base surface, and ensure that the base surface is dry and flat, no hollowing, cracking, oil stains, and the strength is not less than the C25 standard, so that the floor paint can be painted.

From your narrative, it's a situation where the ground is not clean 100 percent, and it is not sandpapered. In a situation like this, there is no remedy but to re-polish and re-brush. Good luck and happiness!

Summary. The floor paint construction unit should clean the ground to be constructed. If you encounter a ground with high flatness, sandblasting or sand treatment should be carried out to improve its roughness and facilitate construction.

2. The ground air drying time should not be too long, generally about 3-4 hours, and the construction should be started. The floor can also be dried at the same time.

3. When building the floor paint, the floor paint manufacturer should choose the material with high geological adaptability to its base layer and ensure that its adhesion can adapt to the material of the floor.

What is the reason why the floor paint falls off, and how does the oily floor paint fall off.

The floor paint construction unit should clean the ground to be constructed. If the ground with high flatness is encountered, sandblasting or sand treatment should be carried out to improve its roughness and facilitate the construction of the group. 2. The ground air drying time should not be too long, generally about 3-4 hours, and the construction should be started.

The floor can also be dried at the same time. 3. When building the floor paint, the manufacturer should choose the material with high geological adaptability to the base layer to ensure that its adhesion can adapt to the material of the floor.

This floor is more than ten years of ground, and the school corridor has peeled off the floor paint just made.

It should be that the roughness of the ground is not enough.

Stir the paint fully and evenly to avoid the color of the paint after construction caused by the delamination of the paint and the original color; 2.Pigments from metals and varnishes are required to be stored separately; 3.Iron drums cannot be used to hold highly acidic paints; 4.

Choose the foundation floor paint with good weather resistance, the quality of the floor paint must first meet the standard, and the next construction operation specification is an important part of ensuring that it is not easy to fade and yellow. In the construction process, the mixing is uneven, the density of several pigments in the compound paint is different, the heavy pigments gradually sink in storage, and the light pigments gradually float, if the use is not fully stirred evenly, it will not match the primary color after construction. Even if it did not fade and turn yellow at that time, it would fade and turn yellow after a long time after experiencing the exposure of sunlight in the hole.

Therefore, it is necessary to strictly follow the construction steps given by the floor paint manufacturer to carry out the construction.

Decoration floor paint is a very common operation, often used in the basement, in the process of painting there are many points that need attention, to operate step by step in accordance with the process, to be careful and serious, after the whole process is completed, we are concerned about the topic of how long can be done after brushing, the following will introduce to you what to pay attention to when brushing floor paint, floor paint brushing is about to be more than a long time.

1. What should I pay attention to when brushing floor paint.

1. First of all, if the floor paint has been painted, the doors and windows of the workshop should be opened to maintain good ventilation, and during the maintenance period, personnel should not wear hard shoes to walk around to avoid the ground being bumped. In addition, it is necessary to pay attention to fire prevention measures.

2. Secondly, when brushing the floor paint, all the operating tools should be placed on the designated frame for easy access, and sharp tools or parts should not be used, once it falls, it will cause great damage to the ground paint.

3. When the floor paint is used normally, if you want to place large objects or machines on the floor paint ground, lay a thick rubber cushion on the ground to avoid direct contact between the feet of the machine and other metals on the ground, thereby crushing or scratching the ground.

4. In the daily use of the floor paint floor, if the ground is damaged, it should be repaired immediately with the paint, otherwise it will be contaminated with debris or oil stains inside the damaged floor for a long time, resulting in the peeling off of a large area of paint on the floor. In addition, if you want to clean the floor on a large area, you can use soap, detergent or water to clean it, and do not use strong acid cleaners, otherwise it will corrode the floor.

Second, how long does it take to finish the floor paint.

1. In different temperature environments, the drying time of floor paint is also different. If the current temperature is between 20 and 25 degrees, the drying time is about 2 to 3 days, which can reach about 80% to 90% of the cure, and by the fourth day, it can reach dryness.

2. If the temperature is relatively low, in winter, the drying time will be postponed, and it may take up to 4 to 5 days to completely dry. Relatively speaking, the time to dry in the summer will be pushed forward, and it will not take 3 days, but it will take 1 or 2 days to dry out. Therefore, it is necessary to determine how long it will take to dry according to the change of climate, humidity and temperature.

The above is what to pay attention to when brushing floor paint, how long does it take to brush floor paint, I hope it can help you understand how long it takes to brush floor paint, more decoration knowledge, decoration company evaluation, decoration cases, please continue to pay attention.

With the improvement of people's living standards, floor paint is widely used by people. When it comes to floor paint, many people will not feel unfamiliar, in fact, many friends have a better understanding of floor paint, but read a lot of Bina consumers are very fond of floor paint, but there will always be some problems in life Next, we will introduce it to youHow to remove floor paint

1.Grind the ground with a grinder.

The first common machine treatment. Use a grinding or polishing machine to remove the old epoxy paint film. This method is relatively common and commonly used.

The second is solvent paint removal. We all know that lye has a corrosive effect, the old floor paint is generally difficult to remove the hollow and bulging shell part, the use of lye to make the old paint film fluffy, compared with the stiff paint film is easy to remove. If you think that the use of lye is more corrosive, there is also a very useful magic weapon on the market - paint stripper.

This is also a solvent, which can effectively dissolve the paint film, and when this solvent is applied to the paint surface, the paint film can be removed with less effort.

The third is the less common method of using flame to remove old paint film. When the original epoxy floor paint and primer are relatively sticky, if the scraper or machine is forcibly used, it is likely to cause damage to the base layer and affect the implementation of the floor project in the future. Therefore, we can use the flame to slowly heat up, use the principle of thermal expansion and cold contraction, make the old paint film soft, expand the bubbles, and then use scraper machines and other tools to remove the paint film.

2.Use a variety of tools.

If you want to make a new floor, removing the old epoxy floor paint is the first step. Royal Flooring has rich experience in floor construction, which can help customers bring different floor space design. In the process of floor renovation, there will be all kinds of "troubles", but different worries, these "troubles" will be handed over to the royal floor to deal with, such as removing the floor paint film of the old ground, Sakura Chi actually chooses different tools according to the site situation to remove, some are because of the bad paint used before, resulting in easy hollowing out of the shell; Some are caused by not paying attention to humidity, temperature and other factors during construction; Others are not used in a reasonable way during the construction process, which reduces the service life of the floor.

2. How to deal with cracking of floor paint?

1.Cause of cracking.

1) The floor is exposed to sunlight or long-term wind blowing, and the floor is dry and shrinking, resulting in cracking of the paint film;

2) The paint film cracks due to the expansion of the floor due to moisture or the floor squeezes each other after expansion and fatally causes the paint film to crack;

3) The moisture content of the floor is too high;

4) The balance of the floor blank is insufficient after drying, and the internal stress is not eliminated.

2.Solution.

1) A small amount can be properly repaired and waxed.

2) In severe cases, it can only be smoothed out after painting.

3) When the number of blocks is small, it can be partially replaced.

3.Precautionary measures.

1) Choose the right paint and the corresponding material, so that the paint film adhesion is the best.

2) The moisture content of the floor is qualified.

3) The tightness of the pavement is appropriate.

The above content is the content brought to you in this issue, in fact, when you buy floor paint, you must choose the most environmentally friendly type of floor paint, so that you can protect our earth.

Summary. Dear, hello, I am glad to answer for you what to do if the floor paint is swept off lightly 1, the ground grinding is not in place, some floating cement is not wiped off, resulting in paint off 2, epoxy primer construction is not in place, less epoxy primer is used, resulting in the adhesion between the epoxy floor paint coating and the cement floor is not firm. Here's how to fix it:

1. When polishing the ground, all the floating sand and crusting cement should be polished off 2. Increase the amount of epoxy primer.

Dear, hello, I am very happy to answer for you what to do if the floor paint is lightly swept away, what to do is 1, the ground grinding is not in place, some floating cement is not erased, resulting in paint off 2, epoxy primer construction is not in place, less epoxy primer, mold takes the lead to epoxy floor paint coating and cement floor adhesion is not firm. The solution is as follows: 1. When polishing the ground, all the floating sand and shelled cement should be polished off 2. Increase the amount of epoxy primer.

It's a water-based floor paint that sweeps off.

Because the water-based paint celery chiral slag paint film is softer than the closed one, the main component is water and some, mineral composition, its solvent is water, so after drying, we wipe with water, sometimes water-based paint will appear, peeling and other phenomena.

How to deal with this.

It can only be solved by repainting. Because fading depends on many factors, such as spraying process, time, ambient temperature, etc., water-based paint is relatively hydrophilic and easier to mix with water, so it will also peel off. Once there is a problem of fading or discoloration, guessing that there is no way to remedy it except for repainting.

Therefore, there are many precautions before and after the construction of water-based paint, and the coating formula of the suitable site is very important. There is also the process of stirring the water-based floor paint material to ensure uniformity and uniform speed, and the stirred water-based floor paint material should be quickly constructed, so as to avoid the problem of fading and discoloration caused by color precipitation after being placed for a long time.

Summary. 1. Remove the position of the floor paint peeling off with a shovel, and then polish the ground again after shoveling. 2. After grinding and smoothing, then apply curing agent on its surface.

Pay attention to the application of the curing agent evenly, especially in the crevices. After the curing agent has dried thoroughly, the cement floor is then coated with cement repair material. 3. Stir the cement repair material evenly, and then apply it to the cement floor, and the repair will be completed after it is cured.

1. Remove the position of the floor paint peeling off with a shovel, and then polish the ground again after shoveling. 2. After grinding and smoothing, then apply curing agent on its surface. Pay attention to the curing agent should be applied evenly, especially the wax reed is the gap position.

After the curing agent is completely dry, then apply cement on the cement floor as a repair material. 3. Stir the cement repair material evenly, and then apply it to the cement floor, and the repair will be completed after its solidification and purity are balanced.

The reason for the peeling and peeling of floor paint 1, product quality factors, the poor quality of the product itself, resulting in insufficient adhesion of primer. Cause peeling, delamination and other phenomena. In this case, Qingshan should choose the primer produced by the regular qualified manufacturer.

2. Improper selection of primerIf the primer is not selected properly, it is necessary to choose a coating variety with good chain sleeve and good adhesion. 3. If the surface of the coated object is too smooth due to the lack of experience of the construction personnel or improper on-site treatment, it will lead to the loss of adhesion between the topcoat and the primer. The surface of the coated object should be sanded first.
