How to use interior paint

First, confirm that the substrate meets the painting requirements before painting;
Second, it should be painted between 5°C and 35°C, and the air humidity required for coating should be less than 85%;
Third, select suitable construction methods and suitable construction tools, and carry out construction operations according to the recommended construction technology;
Fourth, control the coating interval, after the recoating time is reached, the next coating can be carried out. Too short recoating time will cause the bottom layer to dry slowly, causing wrinkles and other problems; one-time brushing should not be too thick.
Fifth, do not mix with organic solvents, acids, alkalis, oils and other chemicals.
Sixth, maintain air circulation during construction, and keep the paint away from direct sunlight and heat sources.
Seventh, in order to avoid contaminating the skin and eyes or inhaling excessive paint mist, please use masks, gloves and other protective equipment.
Eighth, if the eyes are contaminated, wash them immediately with plenty of water and ask a doctor for treatment.
Ninth, place it out of the reach of children.

The process of interior paint

1. Before scraping putty, spray and brush a piece of glue on the concrete wall (water: emulsion is 5:1) to spray evenly without any omissions.
2. Fully scrape putty. When scraping putty, scrape horizontally and vertically, that is, the first time the putty is scraped horizontally, and the second time the putty is scraped vertically. Note that the putty should be scraped off when rubbing and closing the head. After each putty is dry, it should be polished with sandpaper, and the putty should be smoothed and the floating dust should be wiped off.
3. Apply the paint for the first time, first up and down when painting. After drying, replenish the putty, and polish it with sandpaper after the replenishment putty dries. After 1 day, you can paint a second time.
4. During the second operation, it is not advisable to paint back and forth multiple times to avoid loosening the first paint film, or there will be significant paint brushing marks, which will affect the quality.
5. In the third coating application, pay attention to the hiding power of the coating, so as to grasp and adjust the tightness of the coating at any time to ensure the uniformity of the color of the coating.

Common sense of buying interior paint

1. Try to buy from a regular store or specialty store with a high reputation. 2. Recognize the marks on the product packaging, especially the factory name, factory address, product standard number, production date, expiration date and product instruction manual when purchasing.
It is best to buy products from companies that have passed ISO14001 and ISO9000 system certification. The product quality of these manufacturers is relatively stable.
3. Purchase products that meet the standards of "GB18582-2001 Indoor Decoration Materials and Interior Wall Coatings of Hazardous Substances Limits" and obtain environmental certification marks.
4. When purchasing, pay attention to observe whether the product packaging container is damaged or bulged.
When buying, you can shake it to check whether there is cementation. Paints with these phenomena cannot be purchased.
5. Generally, most shops cannot open cans on the spot to check the inherent quality of the products, so consumers must ask for valid vouchers such as the purchase invoice and construction instructions when buying.
6. Before use, open the can to check whether the paint has delamination, sinking, agglomeration and cementation.
If the paint is still in an uneven state after stirring, it cannot be used. Negotiations should be made immediately to the shop where you bought it.
7. Coating construction is also a very important link. The construction must be carried out in strict accordance with the requirements of the product construction manual, and attention must be paid to the matching of the bottom, middle and surface of the coating.
8. The construction environment should be ventilated. If the product has requirements for the construction environment, it must be carried out according to the requirements.
