Really stone paint white what reason, how to solve?

What reason is really stone paint white? How to solve? At present, the wall really stone paint is widely used in building exterior wall decoration, because really stone paint with other coatings do not have advantages. The outer wall really stone paint production process is simple, low cost and excellent performance, with environmental protection, high elasticity, non-stick dust, etc. Series of higher level development of broad prospects. With the popularity of really stone paint, some really stone paint products there are some common quality defects, such as whitening. Below is the fujian KeBao paint in really stone paint on the surface of the white outline. 'Really stone paint' the root cause of the 'white' phenomenon is decided by the factor of the system itself really stone paint material. As we know, really stone paint film thickness is usually thicker than the ordinary latex paint dozens or even hundreds, Emulsioni paint film thickness of about 20 - 30 microns, and really stone paint film thickness reach 2 - 3 mm) 。 In addition, really stone paint the molecular structure of the surface material is very dense, high weatherability, water vapor permeability. Thus, really stone paint is completely dry ( Measured the moisture content was less than 3%) , the glass transition time is relatively long. The survey found that the following reasons can lead to 'white' phenomenon in a really stone paint: ( 1) Spraying really stone paint, the air temperature is low, or high air humidity, the dry degree of coating and the lower level of vitrification coating moisture content is too high. In this case, if the paint, the moisture in really stone paint will evaporate more slowly. When the outside air temperature is low or when water vapor is bigger, really stone paint moisture condenses on the surface of paint film, causing surface appear white, sometimes white coating will soften. ( 2) Use do not conform to the requirements of paint, paint water resistance is poor, or paint brush, scrub insufficient number of leakage in the construction process, and lead to external water intrusion and surface become white. ( 3) Really stone paint formulation system defects, poor water resistance, not only causes white surface, and even cracking fall off. Based on the above reasons, it is recommended that the following measures are taken to prevent the occurrence of 'white' phenomenon: (stone paint 1) For poor drying or uneven wall, should choose series seal primer, epoxy coating must besmear is in place, not besmear brush or leakage, in order to increase the wall of water cut off. ( 2) Construction process, if the environment is not easy to cause pollution to really stone paint, as far as possible put off paint coating, in order to improve the drying and curing degree of really stone paint. ( 3) As far as possible use oily or high weatherability resin paint finish, and in the proper position is used, in order to increase the protection of really stone paint, to prevent the intrusion of external water vapor. True stone lacquer is one of the main material of the modern architectural coatings. When choice really stone paint, you must choose a good manufacturer.
