What should I do if the freshly brushed primer is bulging?

The drum of automobile paint should be removed from the paint surface of the bulge, done anti-rust treatment, and then filled with putty, and then waited for the putty to dry thoroughly, then polished and smoothed, and finally sprayed with paint. If there is a bulge in the car paint, the quality of the car paint or the operation of the paint repair, you can make a claim, it is best to go to a regular professional repair shop or 4S shop for appraisal and find a professional to deal with it.

It can also be caused by rust on the metal under the paint after being wet. If the paint bulging is not dealt with in time, not to mention the impact on the appearance, the bulging area will slowly expand, and finally lead to the paint cracking and falling, which will damage the body, repair trouble, and expensive.

There are generally 4 reasons for the bulge on the wall:

Reason 1: Generally, the wall foundation at the bulge is not well treated, one is that the construction is not clean and floating, and then the wall is oily or waxy things, reason 2: the construction is not standardized enough, the wall base layer is not dry on the latex paint surface layer, it may also be caused by the original cement layer is not cleaned before scraping putty.

Reason 3: The material itself is not good, such as putty glue problem.

Reason 4: The interior of the wall is damp.

The specific steps are to shovel off the blistered part of the cement wall, seal the bottom with a primer, dry and then scrape the putty, and then polish, primer and topcoat. If you want not to affect the aesthetics, you should spray (brush) the entire blistered wall at the end, because of the newness, the texture will be poor.

Specific steps: 1) Shovel off the blistered part and see the cement wall.

2) Use a sealing primer to seal the bottom first, and then scrape the putty after drying.

3) Then sand, primer, topcoat.

4) If you want not to affect the appearance, you should spray (brush) the entire blistered wall at the end, because of the new age, the texture will be different.

Recently, the phenomenon of bulging walls after painting at home may also be due to the problem of internal dampness, and the fundamental solution is to knock off the wall at the bulge and re-dispose of it. The specific steps are to shovel off the blistered part of the cement wall, seal the bottom with a sealing primer, scrape the putty after drying, and then polish, apply primer and topcoat.

If you want not to affect the appearance, you should respray or brush the entire blistered wall at the end.

If the wall is damp, it is easy to bulge, that is, hollow, and it is easy to fall off. You'll have to shovel out the hollow parts of the wall, and then repaint and paint the topcoat. Another possibility is that you didn't apply the primer, which is actually a very important procedure.

Chenguang primer has excellent alkali resistance and strong adhesion, which can avoid the contact reaction between the alkaline cement surface and the topcoat. In my house, we have both: I haven't applied a primer, and I haven't kept it dry.

Because it is close to the bathroom, the wall is often exposed to moisture, and it has already fallen off before it arrives for a year. After shoveling, repaint, make sure that the paint is dry thoroughly each time.

It is the bottom layer of putty that is not firm The reason for depowdering is to shovel off from the new stucco.

This is what is often referred to as a hollow drum in architecture. should be knocked out and re-plastered.

If it is more serious, you need to remove the wall and redo it, brush a little more alkali-resistant primer, and then paint the topcoat. If it's very small, repair it with a topcoat, but this is more troublesome. It is recommended to eradicate and redo it to avoid the problem of panalkali after a long time.

The primer is not well treated, it needs to be removed and repainted, at present, the home decoration is very popular is the mineral coating, which does not contain solvent additives in latex paint, does not contain any chemical harmful components, and the environmental protection coefficient is excellent, and it is very popular in Europe and the United States. The construction is convenient and can be partially repaired.

Shovel, redo, brush with alkali primer, then finish coat.

The main reason is that the base layer is not handled well, the interval between sprays is a little short, the solution is the bubble that has just been bulged, you press it immediately, and it can be glued, and it will not be visible when it is dry, and it will not affect the quality!

It depends on how it is bulging with the cement inside, if that is the case, it is a construction problem, it is not a big deal, the drum is snatched away, and the plaster or cement is used to make up the putty in the brush

It could be caused by the walls being too dry!

Clean up the bulging place!

Re-squirting is fine!

There are two possible reasons why there are several bulges on the walls after 4 months of latex paint:

1. The possible reason is that there is a layer of cement floor in the house, and the wall will "eat" the water;

Second, it may be that the water ran through the water during the renovation.

Treatment: Knock off the hollow drum part and repaint the wall, pay attention to the need to wet the wall the day before painting. The thickness of the painting should not be too thick.

This situation should be caused by a damp wall, and if the wall is wet, then it means that there is a leak in the pipe somewhere in the room adjacent to it. If there is a bathroom next door, then there is a greater possibility of water leakage in the bathroom.

If you want to do interior wall insulation, this does not matter, if you scrape putty directly on it, it will not be long before it will bulge!

If there is a bulge on the wall, it is generally because the wall foundation at the bulge is not treated well or the inside of the wall is damp, so the wall at the bulge is knocked off and re-treated.
