保定市防水材料有限公司

Waterproof coating is a very popular decoration material in recent years. It is mainly used for waterproofing. But now, there are many kinds of waterproofing coatings on the market, and the development of the coating market is very fierce. Some merchants have to fish for water and sell some inferior coating products to consumers. If consumers do not understand the method of correctly identifying the good and bad coatings, it will be unavoidable. Now let me introduce how to identify the quality of waterproof coating.

第一：柔韧性的检测

First: flexibility detection

在平板玻璃上面涂刷防水涂料三到四次，厚度约为1.0-1.5毫米，待涂层实干后，用手去拉伸，看看是不是有弹性，再在一根直棒反复缠绕，看看是否出现裂纹甚至断裂。

On the flat glass, paint the waterproof coating three to four times, the thickness is about 1.0-1.5 millimeter. After the coating is done, it is stretched by hand to see if it is elastic, and then repeatedly wound in a straight stick to see if there is a crack or even fracture.

第二：粘结力检查

Second: inspection of bond force

如果是双组份的防水涂料，可找一块比较干净的水泥基面，然后涂刷三到四次，一周后用铁铲揭一下看是否牢固。

If it is a two-component waterproof coating, you can find a clean cement base, then brush it three to four times, and use a shovel for a week to see if it is firm.

第三：耐水性检查

Third: water resistance test

将涂料分多次涂刷在水泥块上，成膜厚度1.0－1.5毫米，放置7天，放入1％碱水中浸泡7天，不分层脱皮，不空鼓为合格。

Coating the paint on the cement block many times, the film thickness of 1 - 1.5 mm, placed for 7 days, put in the 1% alkali water soaked for 7 days, no delamination, no empty drum to be qualified.
