Painting, is there anything special about it? Just use a brush and paint away~ Can't you just roughly paint it? °³° If you start painting with such a casual mindset, there are many cases where you end up regretting it completely later. ^ ^; Just because you fail miserably doing it alone, saying Ah~ this is not for me. (¯―¯٥) It's better to hire someone after all. Don't think like that, if you watch this video carefully, anyone can do it without any failures. Even our moms can do it.ㅎㅎ It's a company famous for paint, Dulux. I will tell you about the 10 most common mistakes in painting revealed by experts from Dulux and how to fix those mistakes. Number 1. Blisters on the wall? When you start painting after buying the paint, it might be fun at first. You may have all seen paint like this before. It's a common thing. If there is moisture on the wall or if there is a lot of dust, grease, etc.

The probability of this happening is very high. You can't just cover it with paint randomly. You need to clean the surface and then paint it. The way to fix it, if the area is not large, is to completely remove the blister with a scraper, apply paint primer to the removed area, and then repaint it. However, if the area is large, there is no other way but to remove everything and start over. 2. Color bleeding. If you paint a light-colored paint on top of a slightly dark-colored paint that has already been painted, the color underneath may bleed through, making it look blotchy and different in color, which happens frequently. Alternatively, if the wall was originally a bit dirty or had something on it, it may happen for that reason. The way to fix it is that even if you paint it thickly, it often doesn't cover well, so before painting, be sure to apply a primer as an undercoat.

It is recommended to paint next. Do not think it's a hassle, and it's better to use a primer separately. 3. Orange peel phenomenon. I also call it the orange peel phenomenon. It's a phenomenon where the surface changes like an orange peel after painting. It often occurs when painting water-based paint on a contaminated surface, mainly due to wax or oil. Even if you paint before it dries, it will still turn out the same, so be especially careful to avoid greasiness on the surface when painting with water-based paint. If there is grease left on the brush, it can cause the same issue, so be careful of this as well. Do not use a brush that was used for oil paint to paint with water-based (acrylic) paint. If you have already started painting and it turns out like that, there is no immediate solution.

First, just leave it alone and let it dry well. There are wet cloths called waterproof cloths that are soaked in water. Please use a fine waterproof cloth, about 500 grit, to gently sand it. Make the rough surface smooth, then repaint it. Step 4. Filler marks are visible. When there is damage or a crack on the wall, filler (putty) is really useful, but if the finishing is not done well, it will show when painted. After applying the filler, let it dry completely for about a day before sanding. You should sand it until you can't feel anything smooth by hand with sandpaper. It's better to use a sanding block if possible. Sanding is physically much harder than you think. (◞‸◟；)

There is a lot of dust... Therefore, when applying filler, do not apply too thickly, but work as cleanly as possible, thinking of replacing it later. If the area where the filler is applied is wide, it absorbs the moisture of the paint a lot, so it becomes difficult if you just paint over it, making it stiff. In that case, mix about 10% of water to make it a bit thinner and apply it as a first coat. Then, paint over it again. Bubbles appear. Sometimes bubbles can form when painting. I once made a wooden table myself, and I experienced this when painting the top. Back then, I didn't know why it happened and thought, Did I buy cheap paint? (³⌓³)? But the problem was not that, it was directly related to the roller, according to the Dulux staff.

This mostly happens when painting with water-based paint using a roller, and it's because the roller type is wrong. However, if you only have a sponge, you have no choice but to control it well with a small amount of paint. The way to fix it is, like orange peel, if it doesn't work properly when painting, there is no immediate solution, so you have to let it dry well, then sand it with a damp cloth and paint. There are things like fiber that you can buy and use. Rollers with long fur are often used for painting things like bricks or stones. Rollers with medium fur are commonly used for general purposes like indoor walls or ceilings, and then the short ones are for smooth surfaces. It should be used gently, so keep that in mind, and it should be about 3 times smoother. When it shakes, it's like playing at a playground and wondering why the paint is old and where it was painted.

Have you ever been told that when you touch it, something like powder sticks to your hands?
Let's start with this. When the paint on the exterior is exposed to sunlight for a long time, it decomposes, and then the salt component, or something like that, comes out.
The proper way to solve this whitening phenomenon, as informed by the paint manufacturer, is to first remove the heavily coated parts as much as possible and then thoroughly wipe with a cloth before finishing.
Oh, this is an alkali system primer, an alkaline primer, but I really don't know the Korean version.
First, apply this red one, and then you can paint the desired paint.
In simple terms, it means applying a fair primer. If mold grows, it means mold is alive in the vents.
Everyone probably knows this, but the cause is moisture.

Now, no matter what, if you can't control the moisture, mold will keep growing. Fundamentally, you need to remove the moisture. Even so, first, to reduce the mold, use a product like bleach to clean it well, then spray an antibacterial product and let it dry. Next, there are mold-resistant paint products. If you apply such functional paint, it should be fine for a while. But ultimately, if you can't control the moisture, mold will win. For places like bathrooms, where moisture is common, you should open the door regularly or install a ventilation fan to regulate the moisture. If moisture builds up on the outside of the walls, you need to apply a coating to the entire wall to prevent mold from growing. This way, mold won't form. Especially for concrete or plaster walls that are still damp after 1 to 2 years, you need to apply a coating because.

Talking about Benz often leads to this.
Or sometimes, in the early stages, there may be a slight moment in the building, so what can you do? It looks so good, but the skewers...
Oh, because it's a common phenomenon in new houses, don't worry too much. Just say this: first, use a scraper to clean off the dust and dirt thoroughly.
After that, use it as a filler and fill in the rough areas on the wall nicely.
Be sure to sand it with sandpaper. That's all you need to do. This can be useful when fixing scratches or holes on the wall.
Sometimes, you may see wrinkles on the wall, which usually happens when the thick paint dries too quickly, causing the skin to wrinkle slightly overall.

Issues will arise. If you paint the second coat too quickly or something like that, it will turn out like this. Unfortunately, the way to fix this is not easy. Once it's done like this, it's difficult to fix only the damaged parts slightly. Therefore, the only way is to remove the rough parts well with a scraper, then smooth it out with sandpaper, and repaint the whole area. Lastly, when water splashes, it leaves marks. When painting in places like corners or exterior walls, if water splashes before it dries, marks will remain. This often happens in places like fences. In this case as well, the only way is to sand it thoroughly with sandpaper, smooth it out, and repaint it. Painting is not as easy a task as one might think. Without proper preparation, there is a high chance of failure during the process. I've been there too.

Knowing the parts where mistakes can happen in advance, and whether you are doing it now or not, will make a difference. If you remember the 10 things I just mentioned well, when you paint later, you will be able to do it without mistakes. The difference between a professional and an amateur is not much. It depends on how well you prepare for this task. When preparing for painting, clean thoroughly, put on masking tape carefully, and check ahead of time. If you do these things, you can do well like a pro. In the next session, I will tell you about how to paint like a pro without making mistakes, such as venting properly. Thank you from Cheongju.
