How long does it take to paint the waterproof paint with the newly plastered cement mortar on the ki

The newly plastered cement mortar on the kitchen wall should wait until the newly plastered wall is completely dry before doing waterproofing. The general drying time of cement mortar and the drying time of wall moisture penetration are generally best after a week. If time does not allow, the minimum should not be less than 48 hours, and the premise of ensuring smooth indoor air is also ensured.

The coagulation time is divided into initial and final coagulation. When the concrete first loses plasticity, it is called initial setting, and when the concrete completely loses plasticity, it is called final setting.

Generally speaking, the setting time of concrete is related to the setting time of cement. For ordinary cement, the initial setting is not less than 45min, and the final setting is not later than 10h. Concrete is about the same.

However, today's concrete is often mixed with some mixtures and admixtures, which will affect the normal setting time, especially admixtures. There are many varieties of concrete admixtures, such as coagulants and quick-setting agents, etc., which can extend or shorten the setting time.

Generally speaking, if the coagulation time is too long, it will not have much effect on the strength in the later stage. The strength of concrete is mainly related to the water-cement ratio and the amount of cement. However, if the setting time is too long, and the concrete is accidentally injured during this time, it is difficult to say that the strength of the concrete will not be reduced.

1 to 2 days The cement mortar on the wall is dry!

It depends on the weather and it's fine 24 hours now.
