Limestone paint rain from the drum how to solve

Limestone paint is a powder sand wall coating, the coating has a certain water absorption.Product formula absorbent, is a very important quality assessment indicators. But if the site construction control properly, there will still be rain and other quality problems.

【Formula water absorption test】

【Rain performance test】

【Permeability test】

More than a rain, water, water detection, Yu-painted limestone paint product performance to meet the quality requirements. However, in the construction, but also to grasp the construction node precautions, otherwise, there is still water problems. In this regard, Yu painted stone technical team experience is summarized as follows:

1. The facade of the external wall (such as railings handrails, windowsill, parapet wall to the top and other parts), must be used thin coating scraping way, the main material twice the amount of control in the 0.8-1.2kg / m2.

2. All construction surface, must be in the first limestone main material close to completely dry (25 ℃, humidity ≤ 85%, about 12h) before the second batch of coating.

3. Install the "drainage tube" in the water pipe to avoid direct erosion of the dry surface.

4. Artisan stone for the company's products unified terminology, is strictly prohibited the use of "artisan stone putty" or "limestone putty" and other words, which can easily mislead customers or construction workers as a putty approved.

5. In low temperature and high humidity environment construction (such as the basement and other parts), should be used thin batch, many times the way construction.Above for the limestone coating water quality problems of node control methods. Three points of material seven points work, strengthen management, intentions to do, it will be the perfect effect of limestone paint and quality reflected.
