  Heilongjiang latex paintYellow with brush marks, roll marks how to solve
  Wall yellowing is more common in light-colored coatings。
  Reason: The base material of the wall is too alkaline or has not been fully dried,The chemical reaction between the alkaline component and the film will cause the film to turn yellow.When the construction environment temperature is too high or the paint film is exposed to sunlight,Easy to cause paint film yellow;The raw materials used for coating are poor in weather resistance and chemical resistance,Yellowing easily;The paint film life is too long,Aged and yellowed under the influence of climate。
  Prevention: In order to avoid paint yellowing, we should choose products with good weather resistance for external walls, if it is high temperature conditions, special high temperature paint should be selected。In addition, before construction, it is necessary to ensure that the wall base is dry, PH < 10, and the anti-alkali sealing primer must be painted after scraping the putty to ensure that the alkaline substances of the wall will not penetrate into the paint film。

  Treatment: The yellowing of the paint film is an irreversible reaction, and the treatment of yellowing of the paint film can only be repainted in accordance with the construction requirements of the specification with strong weather resistance and strong chemical resistance。

  After drying, the paint film is not smooth, brush marks and roll marks are obvious, and not beautiful。
  原因:1.The construction temperature is too high, the wind speed is too high, and the paint film dries too fast;2.Substrate absorption capacity is strong, the paint film does not have enough leveling time;3.Improper selection of construction tools;4.The product itself has poor leveling。
  Prevention: In order to prevent roll marks and brush marks, we must choose high-quality latex paint and carry out construction in strict accordance with the requirements of the manufacturer。In the construction to avoid high temperature, strong wind weather, the substrate absorption is too strong to use a good sealing primer, and choose the right construction tools。
  Treatment: To treat the paint film roll marks brush marks must be completely dry after grinding and smoothing, and then use a good smooth latex paint specification to repaint。When using rollers, make sure that the wool length of the rollers meets the requirements of the type of latex paint used。
