How many times is it suitable to spray several times? Many people in the construction of true stone paint on the exterior wall, some of the molding once, but there are two molding, in the end is a good molding or two molding?
1. It is difficult to master the thickness of the coating by one-time molding, especially for the new sprayer, it is easier to cause construction defects.
2. The construction defects can not be overcome by one-time forming, but the second-time forming can take salvage construction to solve the problems caused by the previous process. Some of these defects are caused by the wall, some are caused by paint formulation, but the construction personnel may not understand these, if a molding then trouble will come, so the secondary molding can play a role in the construction risk of firewall.
3. One-time molding because the amount of paint is too large to eject is often not smooth enough, in the case of thinner true stone paint slightly inadvertently will flow. Secondary molding of less paint, fan atomization effect is good, easy to control, ejection is very flat, after a little grinding feel is much better.
4. Once molding can reduce construction risk and reduce cost. Sometimes the construction depends on the weather to eat, especially in the rainy season in the south, if the wall is not dry, or rain, in the situation of rush period may appear reluctant to work, if it is a formation after the discovery of paint whitening loss is large, if the first thin spray, dry after the paint did not whiten, basically no big problem In case of a slight whitening, the construction period can be covered if the construction period is delayed two times. Even if the construction period is too tight, then dry through the previous true stone paint on the follow-up moisture will play a blocking role, for the second construction of paint drying to buy time, such as the paint after the water will not bleach out.
5. Intuitively, many people think that the second construction consumes a lot of paint, the theoretical basis is that the second construction hit the hard wall twice rebound landing stone powder. But according to our experience, the amount of paint consumed is almost the same as that of the two construction. Because the thickness of a construction is not easy to grasp, often sprayed thick (because jerry-built material is intentionally sprayed not yo), the second construction atomization effect is good, the amount of paint is accurate, and then consider the secondary construction brings other benefits, the cost actually saved a lot.
6. According to our construction experience, for yellow, red, orange, coffee these colors in particular to the secondary shaping, otherwise it is easy to "flower" off.
In view of the true stone paint construction once formed or twice formed, read the analysis of the above six points should be more clear in the heart of everyone, hope that the finishing of the true stone paint knowledgeable to help you.
