Can cement waterproof coating be used directly with water? Do you need Gaza or cement?

If you don't know, please be careful, cheating!

There are two kinds of cement-based waterproof coatings with international product quality: one-component and two-component one-component water for direct use (water is not added casually, please find the product description when adding water); Two-component emulsion is generally prepared by the manufacturer according to the formula, and water is generally not needed (unless the weather is dry and the temperature is high and the emulsion is too thick). No matter it is a single component or a two-component one, Gaza and cement should be added, which will greatly reduce the waterproof performance of the waterproof coating.
