Painting problems, painting problems, urgency

Wait for the varnish to dry and then paint red.

It may be due to the following reasons:

The primer does not dry thoroughly: the primer must be dried before the topcoat can be brushed, otherwise there will be problems in the interface between the topcoat and the primer, resulting in paint eating and unevenness.

Over-coating of the topcoat: Coating too thick can cause the topcoat to shrink when the surface dries, forming fish scales or cracks, and may also lead to uneven surfaces.

Improper painting tools: Using a low-quality brush or roller can result in uneven coating thickness and can also leave marks on the surface.

High ambient humidity: Painting in a humid environment can lead to poor adhesion to the paint surface and can also lead to uneven surfaces.

It is advisable to wait for the primer to dry before applying the topcoat, and make sure to use an appropriate brush or roller to avoid over-coating the coat. At the same time, pay attention to the ambient humidity and temperature to maintain a suitable working environment. If the problem persists, consider reapplying the primer and topcoat.

It could be due to the following reasons:

The primer is not dry: the primer is not fully dried, which leads to the mixing of the primer and the primer when brushing, which affects the quality of the topcoat.

Uneven dosage of jujube paint in the face liquid: When brushing the topcoat and making noise, the dosage of topcoat is uneven, resulting in inconsistent thickness of the paint in some areas and the formation of traces.

Improper choice of brush: the brush is of poor quality, the bristles of the brush are not soft enough, and it is easy to form burrs on the surface of the paint.

Solution: Wait for the primer to dry completely: Wait for the primer to dry sufficiently before applying the topcoat.

Control the amount of paint used: Know the amount of topcoat to cover the entire surface evenly.

Choose the right brush: Choose a ***, soft-haired brush that can reduce burrs on the surface of the paint.

Hope the above advice is helpful to you.

In the process of home improvement,PaintIt is a science, brushing well is undoubtedly the icing on the cake, if once the brush is not good, not only can not present the desired effect, but will waste materials! Let's analyze the common problems when painting for you, I hope you can guess the group to understand!

Frequently Asked Questions about Painting Operations:

1. Hand painted *** or spray painted?

Some home decoration uses oil mixing technology (the use of blended paint, etc.), for people who do not know much about construction, this practice seems to be easier than varnish, in fact, this construction practice is much more difficult than the varnish practice, pure as a test of the painter's craftsmanship. Workers with poor craftsmanship are prone to brush marks in their work, so in order to improve the quality of the project, many construction sites have recently begun to use the painting process for oil-mixed construction. The quality of this method is much better than that of manual work, but the disadvantage is that it is more wasteful of materials.

2. How many times do you brush the ceiling and wall paint?

Generally speaking, if the background color of the wall is relatively light, the ceiling and the paint on the wall can be brushed twice, but if the background color is darker and the paint color to be brushed is lighter, it should be brushed several times according to the degree of coverage of the paint color. However, it should be noted that it is not the more times the paint is brushed, the better, if the number of paint brushes is too much, there will be peeling and cracking.

3. What protective measures should be taken for the hardware when the painter brushes the paint?

We sometimes find that the painter paints the hardware installed on the wood products (such as door locks, hinges, etc.) when they are painted, and as a result, the owner will find that the surface of the hardware is corroded after moving in. Therefore, before painting, painters should put some single-sided tape tape on the parts that are easy to be painted, so as to protect the hardware.

4. How many times is the nitro varnish on the orange products of the wooden spike pants brushed?

Since the paint film of nitro varnish is relatively thin, the painter should brush it several times according to the situation, and generally should brush it at least six times. However, there is a premise that the painter should clean the surface of the paint before brushing each coat of paint to avoid the paint covering the foreign matter in the back.

Frequently asked questions about painting operationsThat's it for you to analyze here, I believe our introduction can help you! Finally, I remind you that when buying a brand of paint, you must choose a brand with good environmental protection and relatively stable quality.

I haven't encountered yellowing, I don't know if it's due to construction or weather.

Ventilation should be on a sunny and dry day, and normal weather is good; When it is cloudy, open the window ajar, and do not open the window for ventilation on rainy days.

Open the window in the morning and close it at night to prevent large temperature differences, or small cracks caused by rain, etc.

Even if all the paints emphasize their environmental protection, odorless, formaldehyde-free, etc., but that's just relatively little, definitely not nothing, don't be in a hurry to live, at least two months, serious gases slowly dissipate, and then release some in the next few months, even after living, there is still a little residual harmful substances slowly volatilized... It's still more than half a year! During this time you can clean every corner (there is absolutely dust you can't imagine), buy furniture, furnishing details, etc. (the smell of newly bought beds, sofas, etc. is also unpleasant).

It is recommended that the most affordable thing is to buy activated carbon, just simple activated carbon, put it in a carton to remove formaldehyde, expose it to the sun 2-3 times a month, and the affordable 7 yuan generation is about 50g. It is best to let it dry for half a year before moving in. The body is more important than everything!

If your paint and wall paint are done at the same time, then the wall paint may turn yellow, because there is a free ammonia in the furniture paint, which is soluble in water. Free ammonia will evaporate during the drying process of furniture paint, if you are painting the wall at this time, or if your wall has been painted but has not dried. The free ammonia will seep into the wall paint, causing it to turn yellow.

The paint is not good and is oxidized. There is a problem with the quality.

It's mainly toxic gases, so be careful.

The paint has not yet dried, and the color will be different if the temperature is different.

Many renovation owners will encounter such a problem: not long after the renovation of the new house, cracks appear in the walls. The cracking of the wall is serious, some of the large area of wall skin cracking, falling off, the situation is slight, there will be long linear cracks on the wall, not only not good-looking, but also often helpless, you can try to solve it with the following methods:

1. In the painting project, the joints are treated with foaming agent, which can make the joints of the building impermeable and impermeable. 2. Seal with special paper tape for paint, and finally seal the edge again with viscose yellow tape, which can effectively ensure the firmness and stability of the base layer and avoid cracking of the wall in the future. At this point, the owner can communicate with the painter during the renovation to ensure that the base treatment is in place to the greatest extent.

Third, there are also cracking problems caused by the shrinkage of putty in the later stage, when the first putty in the construction is not dry, immediately scrape the next putty, and then brush the paint, it is easy to cause the surface layer of the putty to crack after drying, it is very difficult to encounter a typhoon like now, especially to pay attention to prolonging the drying time of the wall after the first brush, continuous rainy days, the air is too humid, the wall is not easy to dry, if in order to rush the construction and hasty construction may leave sequelae, after the wall cracks, repair is more troublesome, First of all, the cracks should be scraped clean, then scraped again with putty, and then painted after drying. In addition, there is also the question of whether it will crack again after repair. Owners who are often on the construction site can also try to illuminate the wall with sunlamps to speed up the drying of the wall.

No matter how thick the paint is, you can't help when you wash the car, the rag or dun cloth is not washed, it can't be cleaned, there are impurities mixed inside, especially the electric car wash, it is easier to scratch the paint, this is not a solution, find a regular car wash, the code grinding is a good point, in fact, waxing is not good to laugh at the model family, and there are more sun lines.
