At present, there are many types of paints on the market, how should we choose to buy paint ? Let's take a look at the precautions for buying paint and the construction process of paint technology.
Notes on buying paint
1. The brands in the paint market vary greatly, and the prices are also very different. Here I want to remind everyone that when buying paints , do n’t be greedy, be sure to choose the brand ’s products, so as to ensure the safety of yourself and your family. .
2. We can see that there are green words on many packages of paint. I naively believe that the product is green. Look at the product quality inspection report; observe whether there is corrosion or leakage at the seam of the iron drum. Phenomenon; pay attention to whether the explicit sign on the iron drum is complete.
3. If you choose imported paints, then you need to choose products with Chinese signs and instructions, to distinguish whether it is environmentally friendly paint, because non-environmental protection paints, because VOC, formaldehyde and other harmful substances exceed the standard, most of them have pungent The peculiar smell can cause nausea, dizziness, etc. Therefore, consumers are reminded to choose carefully if they smell an irritating smell when purchasing.
4. Before you buy, you can open the paint bucket and test it yourself. If there is serious delamination, it indicates that the quality is poor; agitate gently with a stick. After lifting, the paint stays on the stick for a long time and covers evenly, indicating good quality; dip a little in your hand and wait for it to dry. It is better to wash it with clean water; twist it gently with your hands, the more delicate the better.
Paint process construction process
1. If it is an old house renovation, then the original grassroots need to be removed. Before scraping the ash, check the original base with a 2 meter ruler. If the error exceeds 5mm, use talc and white cement or gypsum powder to level.
Second, the alkyd varnish must be painted on the base layer of the wooden board, jointed with wood glue powder or putty, and then kraft paper or a special bandage should be attached.
3. For the first putty, you can use a 1-1.5m ruler to scrape, and find the verticality and flatness of the yin and yang angles through the ink line.
4. After the first putty is completely dry, you can start to scrape the second putty. The second time putty is mainly to deal with the wall to ensure that the wall is smooth and flat.
Fifth, the third putty is mainly for local repair. You can use the side illumination of a 200-watt light bulb to check the flatness and make repairs.
6. After applying the primer, use the primer to adjust the putty to make up and polish, and then start the topcoat.
7. The topcoat can be applied by brushing or spraying. If brushing is used, it should be applied from top to bottom, first vertically and then horizontally, firstly after the ceiling and then on the wall, and there should be no obvious brush marks or flow. If spraying is used, special spraying equipment must be used.
8. After the first coat is completely dried, you can start to apply the second coat, at least two hours apart. The construction of latex paint should be carried out at a temperature of more than 10 degrees Celsius, and the doors and windows should be sealed to prevent air circulation, and the windows should be opened for ventilation after two hours of painting.
9. After finishing the second coat, you can check and accept it to ensure that there are no scratches, sagging, orange peels, etc. on the wall.
