Sometimes it is the old wall paint that gradually detaches itself from the substrate, but in some cases a new coat of paint also peels off: This is not a pretty sight – and certainly not a basis for another coating. If you are in the same boat, you certainly need to know how to fix chipped paint on wall.
First you should find out what the peeling of the wall paint is, then it is time to take appropriate countermeasures. One thing is certain: there is a lot of work ahead of you!
Why is my old wall paint peeling off?
In the case of older paints that have lasted for many years, the suspicion is obvious that something in the wall has changed. Perhaps moisture has accumulated inside, which, together with the associated efflorescence, pushes the paint off the wall.
It may also be due to the fact that there are simply too many layers of paint on the wall and the different tensions over the years lead to chipping. Take a close look at the wall, scan it and possibly use a moisture meter.
You can no longer save the peeling wall paint, but the wall can! Moisture damage must be repaired urgently so that no mold forms, but the old coating should give way in any case.
Remove leafy wall paint: Here’s how!
A leafing wall paint must be removed, it can usually no longer be strengthened. Especially if the wall already bears too many layers of paint, a new coat of paint is no longer possible without removing the old paint.
Depending on the level of difficulty and adhesive strength, work with the following tools and equipment to get the paint off the wall:
- Hand spatula
- Wire brush
- Grinding sponge
- Milling machine
- Hot air hairdryer
Protect your eyes and respiratory tract with appropriate protective mask and goggles during this work. This stops splinters and dust from entering your lungs or other sensitive areas.
The freshly painted wall paint peels off – what now?
If a freshly painted wall paint peels off again, then something is wrong with the substrate. Either it was too absorbent or too little absorbent, too smooth, too moist or too crumbly. The problem with the paint layers that have become too numerous can also take effect here again.
So, unfortunately, you were happy too early and should remove the wall paint at least at the leafing places, in order to then prepare the substrate accordingly for the repainting.
Tips & tricks
If only a small area is affected by the peeling of the wall paint, stick an adhesive tape on the still adhering areas and peel it off at a steep angle with a jerk. This will help you find out if there are any other vulnerabilities.
Repairing paint defects
Painting defects are a real plague for all painters. In most cases, it is possible to repair the drain marks, bubbles, exfoliated areas or cracks, which are often due to a poorly prepared substrate. Simply equip yourself with the necessary tools and suitable color and follow this guide step by step!
Fix paint defects
With a well-prepared surface, the painting is guaranteed to succeed, that’s no secret. If instead it was poorly prepared or not prepared at all, the result leaves much to be desired. However, there are no magic tricks in DIY either, so do not let your head hang, but have patience and correct the mistakes. All is not yet lost, with the right tools, unsightly spots on the wall are quickly a thing of the past.
You will need to prepare some tools and materials such as:
- Paint rollers
- Crepe tape for masking
- Levelling compound
- Adhesive primer
- Personal protective equipment
- Protective mask
- Painter’s suit
The list here is not exhaustive. Personal protective equipment must be adapted according to the work to be carried out.
1. Remove traces of expiration
In most cases, traces of expiration are quickly noticed. They arise either because the paint does not hold and rolls off the substrate, or because the roll has been poorly wrung out or is too full of paint.
If the paint rolls off the wall, stop painting immediately! You were lucky that you noticed the damage in time: wipe off the paint, sand the substrate slightly and apply a universal primer.
In case of paint forms drain marks when drying, you can only sand off the drain marks until they are gone. Be sure to always wring out your paint roll well in the second layer and not absorb too much paint at once.
2. Repair exfoliated areas
It is only a very small part of the wall peeled off? Lucky again! If instead the whole wall peels off, a lengthy work awaits you.
To repair a small spot, grind the affected area to make the error disappear as much as possible. Then apply a thin layer of leveling clay with a spatula, roughen the area slightly, and then apply an adhesive primer.
If your entire wall is peeling off, you can only use the scraper to first remove everything and then grind the wall to create a uniform surface! Peeling paint should never be painted over, as the new color would not hold either. Do not take any risks and start with the bare ground from the beginning. Apply a primer first, then your color.
3. Eliminate bubbles
Bubbles often form on the paint when it is too damp or too warm in the room. If there are too many bubbles, you need to completely sand the wall. The best way to do this is with an electric sander, with which the dry paint can be easily removed. Before repainting, apply a primer that is suitable for your wall.
4. Repair visible stripes
You can see exactly how you painted with the paint roll from the stripes? This is indeed not very aesthetic. But it often happens with semi-gloss or cheap colors. But don’t worry, there’s a solution here as well:
- Choose matte color
Matte colors have the advantage of concealing small defects, as they do not reflect light reflections. They are ideal for ceilings, but also for bedrooms, offices or living rooms. You can do without cross-painting, as the light streaks are virtually invisible in matt paint. However, you should not forget that matte paint is only easily washable.
- Paint with semi-gloss paint
If you prefer to paint with semi-gloss paint, be sure to cross the line, from top to bottom and from left to right, on squares of about 1 m². Most colors only need one layer because their texture is so creamy that the color spreads perfectly, which is not the case with cheap satin colors. They are low in pigment, they require two thick, uniform layers that are applied crosswise.
However, silk matt paint has the advantage of being washable.
- A good alternative: velvety matt paint
With velvety matt paint you kill two birds with one stone! It can be washed off just as well as silky matt paint and conceals stripes just as well as matte paint. In addition, even with velvety matt paint, it is not necessary to cross over!
Fixing damaged wall paint can be exhausting. But you can do it faster if you know how to do it properly. With filler and wall paint to the new wall! With the simplest craftsman skills, an old wall covered with cracks can look like new again.
