By sunny In the decoration process, the use of latex paint is extremely common, but many people have many misconceptions about latex paint, these ‘latex paint mistakes’ may lead to poor results or even rework. Below we will analyse in detail the common latex paint mistakes, and give the correct approach.
Misunderstanding 1: primer is not very useful, do not use can be
Many people believe that as long as the wall has been scraped putty, primer does not seem essential. However, this is not the case. Whether it is a new wall scraping putty, or old wall renovation scraping putty parts, must brush primer.
This is because most of the putties widely used nowadays are water-resistant putties, which are relatively alkaline. The primer has an anti-alkali effect, if you don’t brush the primer, putty alkali phenomenon is very likely to occur, which will lead to the wall becomes flowery, seriously affecting the aesthetic.
So, what is the correct approach? When mixing primer, add as little water as possible. And, after applying the primer, the interval with the topcoat afterwards should not be too short, preferably not less than 24 hours. If the interval is too short, even if the primer is applied, the putty may return to alkali. Therefore, in this part of the brush primer, must be strictly in accordance with the requirements of the operation, in order to avoid the subsequent emergence of a variety of problems.
Misunderstanding 2: The smoother the grass-roots treatment, the better
Most people are clear that before the construction of latex paint, the wall needs to be treated to ensure that the wall is free of bubbles, cracks, dust, etc., so that the effect of latex paint after construction will be smooth. However, many people fall into another misunderstanding, that the smoother the wall base treatment, the better.
In fact, the wall is too smooth is not good. If the wall is too smooth, or the presence of oil, the wall is easy to peel after painting, which will undoubtedly seriously affect the decorative effect. When the grass-roots level is too smooth, the adhesion of latex paint and the wall will be reduced, and it will be easy to appear peeling phenomenon over time.
The correct approach is to use just brush the grass-roots level bristle, which can increase the roughness of the grass-roots level, improve the adhesion of latex paint and wall surface. At the same time, use solvents to remove the oil stains, to avoid the oil stains affecting the coating effect of emulsion paint. Through such treatment, it can create good grass-roots conditions for latex paint construction and ensure the quality of the final decoration.
Misunderstanding 3: Layered latex paint can not be used again
After renovation, if there is some latex paint left, many people will put the lid on the bucket and put it in a cool and backlit place to save. But after a period of time, latex paint may appear layered phenomenon. Many homeowners see this situation, they think that the layered latex paint can not be used again.
In fact, this idea is wrong. As latex paint is a water-based solution, the phenomenon of layering is very normal. As long as the latex paint does not appear yellowing, mould, odour and so on, it can still be used normally after mixing it well, and it will not affect the final painting effect.
When storing latex paint, as long as you follow the correct method, put the lid on the bucket and place it in the right environment, even if there is delamination, there is no need to panic. When using, just use the mixing tool to fully mix the latex paint, you can continue to use for wall painting, both to save costs, but also to avoid waste.
Misunderstanding 4: hand feel white powder, paint quality problems
After painting the wall, with the hand may stick on the white powder, many people will be nervous when they see this situation, thinking that the paint has quality problems. But in fact, the fall of the ‘powder’ most of the dust on the wall. In the construction process, a lot of dust will slowly adhere to the wall, after touching the hand may appear similar powder phenomenon.
Encountered this situation, with a duster or clean towel to wipe off the dust can solve the problem. However, if the quality of latex paint is relatively poor, containing too much moisture, less emulsion, the wall may appear after one or two years after painting with a towel after the phenomenon of falling powder. But even with this type of paint, the powder will not come off when you touch it with your hands.
To avoid this, it is best to touch the emulsion paint by hand 24 hours after it is applied to the wall. If the construction temperature is below 5°C, this time should be extended to a week. In addition, before buying latex paint, it is best to ask the merchant about the grade of latex paint. Medium and high-grade paint generally speaking will not fall out of powder, but the lower grade of paint is less resistant to rubbing, more likely to fall out of powder phenomenon. Therefore, when choosing latex paint, according to their own needs and budget, choose the right grade of products.
Misunderstanding 5: The more expensive the latex paint, the better the effect of brush out
Many people think that the wall effect after the construction of latex paint is only related to the quality of the latex paint itself, and feel that the more expensive latex paint, the better the effect of the brush out. But in fact, the wall effect after the construction of latex paint is affected by the quality of the latex paint itself and the double impact of the construction process. Like a ‘good horse’ needs to be equipped with a ‘good saddle’, and then good latex paint, if there is no good construction technology, it is difficult to play the maximum effect.
The higher the grade of the paint, the higher the content of emulsion and other raw materials, the higher the requirements of the construction process. If the construction process is not pay attention to, such as adding water in the wrong proportion, grass-roots treatment is not in place, the interval time does not meet the requirements, in fact, more likely to appear on the wall brushing the phenomenon of flowers.
Therefore, before the construction, must require the construction personnel in strict accordance with the product description of the construction requirements for construction. In particular, attention should be paid to the amount of water, grass-roots treatment and the interval time marked in the product description of the three requirements. Only to ensure that the construction process meets the standard, in order to let the latex paint to play the best effect, to create a beautiful wall.
Misunderstanding 6: Qualified latex paint is environmentally friendly
Judge whether the latex paint is qualified and whether environmental protection, the use of different national standards. Many consumers think that as long as the latex paint is qualified is environmentally friendly, this is a misunderstanding. Only through the national green ten ring certification of latex paint is truly environmentally friendly products.
So, how to identify whether the latex paint through the green ten ring certification? Only through the green ten ring certification of latex paint products will be affixed to the surface of the corresponding label, consumers can check whether there is this label when purchasing. At the same time, you can also ask for a test report from the National Coatings Quality Supervision and Inspection Centre to check the VOC (Volatile Organic Compounds) and other indicators.
The lower the value, the more safe and environmentally friendly products. China’s environmental labeling certification standards require that the VOC content of the wall paint after removing water to be less than 80 g / litre. Therefore, in the purchase of latex paint, be sure to carefully check this information, choose a truly environmentally friendly products.
Misunderstanding 7: Scrub resistance index is high, the wall can be towel scrubbing at will!
Many people have a misunderstanding of the number of times the latex paint scrub resistance, that the number of times the scrub resistance index is high, the wall can be scrubbed with a towel at will. But in fact, the number of latex paint scrub resistance is to use a special machine brush in the paint surface wipe test out, rather than with a towel this material tool to test out the results.
If you use a towel to rub the wall as hard as rubbing clothes, there is a possibility that the paint film will be rubbed, even if the number of times of scrub resistance is very high latex paint may fall powder. Therefore, not because of the high number of times the latex paint scrub resistance to use a towel to vigorously wipe the wall.
The correct approach is to use a wet towel to wipe off the stain with normal vigour if it appears on the wall. If the stain exists for too long, the bad quality of the paint may penetrate, it is not good to remove. Therefore, in daily life, to clean up wall stains in a timely manner, to keep the wall clean and beautiful.
Misunderstanding 8: doors and windows open wide to disperse odours
Although latex paint belongs to the water-based paint, environmental performance is excellent, but many owners still like to use the windows and doors wide open. They do this for the purpose of accelerating the drying of the wall, the second is to disperse the paint odour. It seems to be a two-for-one approach, but in fact it is not.
Especially in the northern dry areas, if the paint drying time is too fast, latex paint in a short period of time rapid water loss, it is easy to cause the wall cracking. Once the wall cracked, and finally had to rework, which will not only increase the cost of decoration, but also delay the progress of decoration.
The correct approach is to open the window a small slit, in order to ensure that the premise of indoor ventilation, so that the wall in 1 – 2 days time to dry completely appropriate. This will ensure that the walls dry normally, but also to avoid the problem of cracking due to drying too quickly.
In the decoration process, we must avoid these ‘latex paint mistakes’, in accordance with the correct method of operation, in order to ensure that the latex paint construction effect is good, to create a beautiful, environmentally friendly, durable wall. I hope you can avoid these minefields in the decoration, and successfully complete the decoration project.
