The worst of latex paint determines the effect of the whole home, the choice of latex paint can not be sloppy, and then we will introduce the precautions for the purchase of latex paint and brush latex paint, I hope it will help you.

First, the environmental protection of wall paint.

Wall paint is used in a large area of the home, accounting for as much as 80% of the total area. The correct way to choose environmentally friendly wall paint is to check the test report of the wall paint to check whether the VOC content, free formaldehyde content and heavy metal content of its environmental protection indicators are in line with the national standards, without losing whether the pungent smell is emitted.

Second, how to choose the color of wall paint.

The choice of wall color is very important, and it should be selected according to the specific room, for example, the wall paint color of the bedroom should be soft and warm, such as orange, pale pink, etc. When choosing a wall paint, there are color card comparisons, the color of the color card is not actually the color of the wall paint on the wall, and after the four walls are painted, the color of the wall will be darker than the color card color. Therefore, it is recommended that consumers choose a color number that is slightly lighter than the color they should choose when choosing a color in the color card.

1.Formula for calculating the construction cost of latex paint.

Formula 1: Saleable area.

The actual number of areas.

Labor cost of one square = actual labor cost;

Formula 2: The actual area.

50 square = the number of paints purchased by the bird;

Formula 3: Number of barrels purchased for topcoat = painting area.

Painted area per barrel.

2. The number of barrels purchased for primer = the area of brushing.

Painted area per barrel.

2.Unit price of latex paint construction.

1. Scrape porcelain: scrape twice in two times, 3 yuan; Scrape twice in a row, yuan; Put a thick scrape again, 2 yuan.

2. Scrape putty: scrape twice, 3 yuan; Single scrape for the second time, 2 yuan.

3. Painting: 3 yuan; Add primer and charge 1 yuan.

4. Repair: a small amount of repair, free of charge; Extensive repair, 25 yuan per hour.

5. Protection: a small amount of protection, free of charge; Massive protection, 25 yuan per hour.

6. Gypsum line whitening: flat double-layer, 2 yuan; Semi-circular with pattern, 4 yuan.

7. Shovel wall: shovel putty or melamine, yuan square.

8. Grinding: 2 yuan square.

9. Main material: latex paint 260

240 yuan. 10. Toning: 20

30 yuan. 11. Auxiliary materials: a number of sandpaper, 1 roller 10 yuan, 1 brush 4 yuan, etc.

1. Odorless is environmentally friendly.

Many people judge the safety of latex paint by smelling it, believing that latex paint with low odor or no odor is environmentally friendly. This is a big misunderstanding. Because odorless coatings can be achieved by adding fragrances or using low-odor materials, odorless paints are not always environmentally friendly and non-toxic.

The most professional way to judge the environmental protection of latex paint is to see whether its environmental protection indicators meet the standards. There are three key environmental indicators of latex paint: VOC, free formaldehyde, and heavy metals.

2. Heavy packaging and ignoring the inside.

It is very necessary for consumers to always look at the packaging of latex paint when buying it. However, it should be noted that the coating with good packaging is not necessarily of good intrinsic quality. In order to attract customers, some manufacturers make a big fuss about the packaging of the product and deliberately exaggerate the efficacy of the product's hail chain tremor.

Therefore, it is recommended that consumers should pay attention to other aspects in addition to looking at the source of product packaging, such as checking the detailed inspection list of the product.

3. The color card is exactly the same as the color of the wall.

Many consumers think that the color of the paint on the color card is exactly the same as the color of the wall, which is a misunderstanding. Because of the reflection of light, etc., after the four walls of the room are painted, the color of the walls will look darker than the color card. The color that consumers see on the color chart is often different from the actual color of the paint on the wall.

4. Do not estimate the amount of paint used in advance.

Many consumers do not estimate the amount of paint used in advance, for fear of buying less paint, and always buy more when purchasing. This may cause a waste of materials, increase the cost of home improvement, and at the same time, the accumulation of too much paint will also have a certain impact on construction safety. Therefore, it is recommended that consumers must look at the area of the construction area before construction, so as to estimate the amount of materials purchased.

The easiest way to estimate the amount of paint used is: the amount of paint required to apply a cavity (l) = (the area of the wall that can be painted per liter of paint).

5. Focus on quality and ignore quality.

When many people buy latex paint, it is easy to fall into the misunderstanding of heavy and ignoring quality. Some people think that the higher the ** of the paint, the better, so when choosing to find the most expensive to buy, but the experimental results show that this is not the case. On the other hand, in order to save money, the lower the purchase, the better, so that the money is saved, but the wall quality and indoor environment will be worrying in the future.

Therefore, it is recommended that you try to pay attention to the quality of latex paint in addition to consideration, and generally choose a reputable one.

1. Observe the aqueous solution: it is generally milky white and has a very thick texture. You can stir it with a brush and see if there are any lumps.

If not, it means that it is of good quality and you can buy it with confidence. Also, remember to look at its brushing. Using high-quality latex paint, the brushed wire is very long and not easy to break.

2. Smell the smell with your nose: If the smell is not pungent, or there is almost no smell, it means that its quality is very good, otherwise it is a defective product, and it is not recommended to buy it. Although it is cheap, it has a lot of toxic substances and may have certain effects on your health after use.

3. Quantity: If it is a first-class latex paint, the weight should be heavier. You can also shake the barrel with your hand.

If it makes a sound, it means that the viscosity is not enough. It is not recommended for everyone to buy. If its size is 5 liters, then the weight should be around 15 pounds, and if it is 18 liters, then the weight is 50 pounds.

When purchasing latex paint, you should choose environmentally friendly, non-toxic and tasteless, the first latex paint will form a thick elastic oxide film, pay attention to the feel, the first latex paint is very smooth and delicate, and the real latex paint will be very scrub-resistant.

Consider its adhesion, consider its taste, consider its safety index, consider the problem of later discoloration, and consider its environmental protection.

4. It can be constructed on the wet wall after the new construction, and the allowable humidity can reach 8-10%, and it does not affect the cement to continue drying.

5. Non-toxic. Even if the construction is carried out in a room with poor ventilation conditions, it will not bring harm to the construction workers.

6. It is convenient to modulate and easy to construct. It can be diluted with water, constructed with a brush or a pen, and cleaned with clean water after the tool is used up, which is very convenient.

7. Do not ignite. Because the coating is an aqueous system, there is no risk of disaster.
