Material selection class: Tips for paint purchase skills
At the end of the year, as the saying goes, the plan of the year lies in spring. When the new year is approaching, many people take advantage of this time to paint the walls and want a new look for the new year. After brushing, there is still time to smell. So how to buy paint? Do you value price, word of mouth or function when choosing paint? Regardless of the price, good quality is the last word. Let's follow the editor to pay attention to the purchase skills of paint.
1. Common paint problems
1. Faded wall
From the beginning, the brightly painted walls were bright and moving, and they became dull or whitish in a short period of time. Was the dilution ratio wrong, or did you buy inferior products?
2. Stimulate the smell
I bought the unheard of paint at a low price, and after opening it exudes a strong irritating smell, which makes people feel uncomfortable and dizzy.
3. Paint toning
I don't like pure white walls, I have chosen a certain color on the color card, and let the merchants paint on the wall after toning, but the color is different from the color on the color card
Second, distinguish the focus
When buying paints, consumers do not understand the paint industry, they may think that the more expensive the quality of the paint products, the better the quality of the paint purchase, resulting in spending money but buying inferior products.
1. Good quality is the last word
Some people buy paint products, in order to save money they will buy low-cost unknown products, the money is saved, but the quality of the wall and the safety of the indoor environment in the future are difficult to guarantee. No matter how high or low the price is, the quality of the paint is the last word, and we must choose green products with environmental protection marks.
2. Standard is more important than brand
Big-brand coatings are more popular than small-brand products, and their credibility and praise are relatively high. Nevertheless, the brand's reputation can only be used as a reference condition for purchase. What is more important is the quality, environmental protection and cost-effectiveness of the coatings.
3. Environmental protection is not singular
The environmental standards of the paint are judged as VOC, free formaldehyde, heavy metal indicators and the actual space air quality after painting, which is not determined by a single condition. The odor of the paint can be removed by additives and cannot be used as a judgment standard.
3. Principle of color selection
According to the color tendency and people's subjective feelings, we divide the hue into warm and cold tones. Generally speaking, red orange yellow and other visually diffusive are warm colors, and blue, purple and green are visually shrinking. It is a cool color, and black and white gray is a middle color.
1. The color of the living room is suitable for both warm and cold
The living room is the most central place in the whole house. It can be used in a large area in cold and warm colors, and will look personalized. The choice of color tone should be matched with furniture. Neutral colors are relatively easy to match and can also meet the needs of people of different ages.
2. Local warm colors should be used on the bedroom wall
The bedroom needs to be quiet and casual, generally use light warm colors, such as beige, orange, etc., the dark part of the bedroom with better lighting can reflect the personality of the room, but to avoid bright colors such as red and purple, too bright colors are not Good for sleep quality.
3. The two extreme dining and kitchen spaces for dining, kitchen and bathroom are suitable for warm colors such as red and orange. Bright colors can stimulate the brain and promote appetite. The reflection of light can also make food look more attractive; the cool color effect of the bathroom space is more Good, it can make the space look bigger visually.
Fourth, paint purchase skills
When buying paint, consumers cannot judge the quality of paint by more professional testing methods, so they can only use some simple and intuitive tips to observe the quality of paint.
1. One look, two smells and three stir
Take a look at the paint for precipitation and agglomeration; second, smell if it smells and irritates; use a wooden stick to mix up the paint, and the high-quality paint will be fan-shaped when flowing down, with good leveling.
2. The color of the color card is not accurate
Due to the small display area of ​​the sample color on the color card, the color will be darker after being painted on the wall than on the color card. Please pay attention when choosing the color. The color on the color card may be slightly different from the actual one. The actual color of the paint shall prevail.
3. Environmental protection
Experience stores will provide paint samples. You can observe the gloss, feel, smell, etc. of the sample. The bright color and strong decoration are better. The sample with a white surface and a pungent taste is a poor quality product.
V. Pollution detection methods
A well-painted house cannot rely on the nose to determine whether there is pollution and the level of pollution. It uses a simple method to detect indoor formaldehyde pollution in order to remove formaldehyde and return you to a safe home.
1. The formaldehyde self-test box The formaldehyde self-test box is a simple detection method to determine the indoor formaldehyde content through the formaldehyde reaction. According to the color comparison of the solution, the color scale card shows indoor formaldehyde pollution, but it can only be used as a transitional method, and there is no accurate data support.
2. The volume of household formaldehyde detector is only the size of a water cup, which is suitable for general household use. Using the latest imported electrochemical sensor and high-precision operational amplifier chip, real-time detection of indoor formaldehyde concentration, when the indoor formaldehyde concentration exceeds 0.1mg / m3, the screen will change color and flash and send out an alarm.
3. The formaldehyde testing agency employs a formaldehyde testing agency to conduct testing, which is more suitable for large organizations such as enterprises and units. It is best to entrust a professional organization to do an environmental testing before the new company or new office is settled, to avoid affecting human health. The testing organization and the governing organization cannot be the same, and their qualifications are checked to avoid fraud.
