Do the math how much it will cost you to renovate your home

1. Process problems.

During the construction, some workers did not follow the construction process in order to be lazy: first apply 1 putty leveling, then apply 2 times of putty, 2 times of primer, and 1 time of topcoat. Instead, it is directly leveled with 1 putty, 1 primer and 1 topcoat, which leads to the infirmity of the wall base, so that after a long time, the bottom layer will be loosened, resulting in problems such as latex paint falling off.

2. Indoor air humidity.

Some owners move in after the wall moisture is not dry, after the owners move in, it is inevitable to use water, resulting in an increase in indoor water vapor, and the combination of water vapor and wall latex paint will form wet latex paint, so that after a long time, the wall will begin to blister, mold, and even fall off in serious cases, so in order to avoid such problems, the owner should wait for the wall to dry before moving in, in addition to using dry powder paint as much as possible, so that the wall dries faster.

3. Material quality problems.

It may also be that there is a problem with the material itself, for example: the use of unqualified latex paint during construction, so that after construction, there will not only be problems such as latex paint bubbles and falling off, but also problems such as excessive formaldehyde, so it is recommended that when you choose latex paint, you should try to make a big brand and have quality certification products, so that the quality is more guaranteed.

The reasons why latex paint comes off are:

Problems with the contact surface of the substrate cause the latex paint to peel off.

When applying latex paint, the wall is not clean, and the workers do not polish and clean the wall, resulting in putty.

The latex paint on the layer does not adhere strongly.

Weather or environmental issues.

Causes the latex paint to peel off.

During construction or use, latex paint is in a humid environment for a long time, which will lead to excess moisture inside, and when the wind blows or the weather is dry, it will shrink and tighten, resulting in peeling.

The quality of the latex paint causes the latex paint to fall off.

The quality of inferior latex paint is unqualified, and it will fall off due to quality problems during use.

How to avoid latex paint from peeling off:

Before decoration, be sure to pre-treat the wall, polish it in advance and repair it with plaster to make the wall smooth.

During construction, avoid long-term excessive humidity in the room and water vapor in the air.

It can also cause the latex paint on the walls to peel off.

When purchasing latex paint, you must choose a qualified brand to avoid quality problems.

That's the disadvantage of winter renovations. If the putty does not dry thoroughly, brush the latex paint, which will definitely lead to cracks in the wall in the later stage. It's not a big deal, just make it up again.

1. If you want to eliminate the quality problems of the house construction, you can find a painter to repair the putty again, and then brush the latex paint. Dirty is for sure, you can find a newspaper mat and clean it carefully after repairing it.

2. There should be no cracks in the problem, unless it is a quality problem in the construction of the house.

3. I don't think you can get this compensation, the decoration company is a black-hearted ghost, and you still want to get the money back in his pocket?? Unlikely!!

In the place where it falls off, the base layer is cleaned and rolled early, first paste a layer of good cloth, kraft paper or newspaper on the wall, and then greasy the land stove and brush latex paint. The tension of the fiber is used to ensure the integrity of the paint film of the latex paint.

You can also remove the insulation board on the surface, or remove the cement wall, install a layer of gypsum board or "five-mile board" outside the insulation layer, and then make latex paint on it, which can remove all the irregular cracks, and the cracks are generally the joints between the plates, which are easier to deal with.

It is the use of elastic decorative materials. At present, there is a material called "elastic putty" in the method of wall substrate treatment, which can make up for the problem of wall cracks to a certain extent in a spare wheel.

This answer applies to most cases where the wall paint is peeling off.

Brushing latex paint wall peeling off is a relatively common phenomenon, and many people will encounter this situation in the process of home improvement. There are many reasons for this, it may be non-standard construction, poor quality of materials, damp environment, etc. No matter what the cause of the latex paint falling off, it needs to be dealt with in time to avoid greater losses.

1. Find the place where it fell off.

Before dealing with latex paint peeling, you first need to find the place where it comes off. You can gently press the wall with your hand, and feel the air or the cracks where you have already fallen off. If you find that the part of the wall bridge is relatively large, you can use a scraper to gently scrape off the loss, so as to avoid ineffective repair or unevenness.

2. Dispose of the place that falls off.

1. Wash. Clean the place that has come off and wipe off the dust and dirt around you. You can wipe it with a damp cloth and wipe it off with a dry towel.

2. Apply primer.

Use the same brand of primer to apply to the peeling part, the role of the primer is to make the peeling part and the original wall interface more solid and reliable, to avoid loosening.

3. Repair latex paint.

Apply the same color latex paint as the original latex paint to the primer, and try to make the painted area larger than the surrounding wall, so that the whole wall looks more uniform and beautiful.

3. Keep it dry.

After applying the latex paint, it needs to be protected from moisture, ventilated, and allowed to dry naturally. Usually, it needs to be left dry for more than 24 hours to ensure that the latex paint is completely dry before proceeding to the next step.

In short, dealing with latex paint peeling off needs to be careful and serious, through the above methods, especially before applying latex paint to choose a good brand and good materials, this phenomenon can be effectively avoided. At the same time, it is also necessary to pay attention to prevent the dampness of the room and the falling off of a wide range of walls, so as to avoid unnecessary losses to the residents.

Situation 1: Peeling of wall paint may be due to the surface being too smooth. If the original paint is varnish or powdery (with untreated colorant paint), the new wall paint will not stick to the surface.

Or it may be that the wood is rotten or the metal has rust spots, or it may peel off due to poor quality of wall paint. For small areas of wall paint peeling, you can first sand it with fine sandpaper, then apply putty, brush with primer, and then repaint. Extensive peeling must be scraped off and repainted.

x0d x0a situation 2: if the wall paint blistered, first of all, the bubble punctured, if there is water coming out, that is, there is moisture infiltration under the paint layer or behind the paint layer, after the sun, the water evaporates into steam, and the patent leather will be blistered. At this point, the blistering wall paint is removed with a hot air spray gun to allow the wood to dry naturally, then primed and finally repainted over the entire patched surface.

In the case of cracks in the wall paint, it is most likely necessary to remove the paint with a chemical paint remover or hot air spray gun, and then repaint it. If the fracture range is not large, then you can use a sanding block or wet and dry sandpaper to dip it in water to grind off the broken wall paint, and after the surface is polished and smooth, apply putty, brush with primer, and repaint.

Latex paint needs a suitable temperature when decorating, and generally needs to be constructed at an indoor temperature of about 15 degrees. If the temperature is too low, it will easily fall off.

Because the temperature in winter is relatively cold, when the latex paint is painted on the wall, it may freeze when it is opened, and the limb friend will not stick firmly to the wall and cover the locust.

It is because we did not have some adhesive in the hall when we were decorating, and secondly, because it was too dry, so it would lead to such a situation.

1. If the area of latex paint falling off is not very large, then only sandpaper is needed, and then the place that falls off is sanded, and then putty is used to coat it. And you must pick the best one in the purchase, the quality is guaranteed, and you can't just brush it once, wait for the first layer to dry, and then brush another layer, so at least two layers must be brushed, and the painting must be even, otherwise the wall will not look very balanced, resulting in the overall effect is not good-looking. 2. If the area is very large, then the entire wall can only be removed, and then polished again, the basic operation is the same, that is, the amount of work is large.

Reasons for this:

1. It may be because when the house was renovated, the quality of the latex paint purchased was not good, such as the adhesion was not strong enough, so even if the painting was successful at that time, and the effect was okay, but it would fall off after a long time.

2. Or when painting the wall at that time, the dust on the wall was not cleaned, and the adhesion was greatly reduced due to this reason.

3. Or because the home is humid all year round, and it is easy to seep water on rainy days, so it will affect the latex paint painted on the wall.
