      Winter paint construction precautions


       

           It is well known that paint is a very delicate and delicate building material. Once the temperature is too low, it will “strike”. Especially when the exterior latex paint is cracked during winter construction, it is necessary to strictly follow the product description when spraying paint. The temperature is carried out. In general, the environment of paint construction should not be lower than 5 °C, the commonly used mixed paint should be above 0 °C, and the varnish is not lower than 8 °C.


           The wall in winter is dry compared to other seasons, and the effort on the wall before the decoration is naturally different. For example, in the summer, because the air is humid, in order to make the wall dry as soon as possible, it is necessary to open the window for ventilation. However, if the window is ventilated in the winter, the paint and wallpaper will lose water and cause shrinkage deformation. Therefore, in winter, not only must the amount of "water replenishment" be given to the wallpaper, but also the wallpaper and wall coverings should be naturally dry. The following small series for everyone to analyze the winter paint construction considerations.

          Winter paint construction precautions


          
      1. Strictly follow the ratio of paint and curing agent provided on the label.

          
      Do not add or add more curing agent at will, otherwise it will cause defects such as bite bottom or cracking. When mixing the paint, it should be stirred evenly, filtered with a 200 mesh filter cloth, and defoamed for 15 minutes before being applied.

          
      2, should pay attention to keep warm

          
      The environment of paint construction should not be lower than 5 °C, the common mixed paint should be above 0 °C, and the varnish should be no less than 8 °C. Some owners are willing to install heating in the winter. Although the indoor temperature has increased, the outdoor temperature is still low. Under the strong opposition of excessively high and low temperatures, it is extremely easy to damage the paint surface.

          
      3, pay attention to the cleaning of the environment

          
      The winter temperature is low, the paint drying time is long, the contact time of the paint film surface with the outside air is relatively long, and the dust particles in the air easily adhere to the surface of the paint film to form a particle phenomenon (more obvious when the air is dry). Therefore, for better paint film effect, please pay attention to the clean environment before painting.

          
      4, the appropriate use of thinner

          
      The viscosity of the paint changes with temperature. When the temperature is lower, the viscosity will increase a lot, which will lead to an increase in the amount of diluent.

          
      5, ventilation of the window should be timely and appropriate

          
      Many owners think that when opening the window, it is necessary to open the window so that harmful gases such as formaldehyde can be dissipated as soon as possible. Xiaobian tells everyone that this is completely wrong. In fact, when to ventilate, when not to ventilate is very particular, opening the window is conducive to the volatilization and drying of harmful substances, but as mentioned above, the paint needs to be "warm", can not start too soon Freezing, premature ventilation allows outdoor cold air to come in, which can cause the paint to pulverize or even deteriorate. The wall paint that is not dry can be easily frozen, causing the wall to change color and peel after warming up.

          
      The door and window should be opened after sufficient drying, and should be selected at a warmer noon time. The ventilation time should also be vigilant and not too long. If you encounter a sudden drop in temperature, you should close the window as soon as possible to prevent the wall from shrinking and causing cracking.

          
      6, construction should pay attention to personal safety

          
      Due to the relatively dry climate in winter, it is easy to cause fire. Therefore, the decoration also needs to pay attention to fire prevention. Garbage chips, waste paper sheets, etc., which are easy to catch fire, should be removed in time, and paints and other items should be placed separately in a ventilated place such as a balcony. In addition, many people in the winter decoration will close the window because the weather is too cold, and the poor quality of the building materials, especially the paint, it is easy to easily emit toxic gases and flammable gases, which leads to unnecessary safety accidents in the interior decoration. It requires special attention.

          
      Winter paint construction sequence

           
      1. Remove dust and dirt from the surface of wood products and lines (wood base).

           
      2. Trim the defects such as burrs and flaws on the surface of the wood base layer, and polish them with sand skin to make the corners neat.

           
      3. Use oily putty (or transparent putty) to scrape, polish, and replenish the putty and polish it. (When using varnish, first make up brown eyes, nail holes, and do partial color repair work).

           
      4, apply the first paint, make up the putty, after polishing, remove the surface dust.

           
      5. Apply the second coat of paint, remove the surface dust after polishing, and grind the water with water sand to repair the part of the oil.

           
      6. Apply the third coat until the desired result is achieved.
