Why does the waterproof layer turn white and powder?

Hello, we have also had such a situation on the wall of our house, and the main reasons for the summary are:

1. Reason: The base surface is very dry.

The weather was cold during construction.

There is no curing. 2. Treatment method.

Before construction, fully wet the base surface.

The construction temperature must not be lower than 5 and this temperature lasts for 8 hours or more.

In the construction of dry weather and high temperature environment, watering and maintenance measures should be taken.

In addition, to do the base surface treatment, the base surface should be guaranteed to be smooth, solid and clean, and there should be no looseness, oil stains, etc. If there are large holes that can be filled with water without leakage, of course, you still have to choose good domestic brands, such as Niu Yuan and Yuhong. Before construction, the base surface must be fully soaked with clean water, but there can be no open water.

The developer of the new house will do the closed water test before handing over the house, and the second-hand old house should be cautious about the closed water test, and it may leak downstairs in the process, even if there is no leakage, there is a high probability that it will resurge, and it must be waterproof after drying.

Problems with the formula.

Add water to your emulsion 1:1, the solids content of the liquid is too low, and in this way, you add 400 sand to your mortar, and still paint.

Is yours a waterproof paint or a waterproof mortar?

Waterproof coating, why add so much sand, and it does not thicken.

If it's a mortar, why is it brushed, I don't know what kind of product you're making.

This method must be whitish, the proportion of powder is up, or the solid content of the emulsion is up, the formula of the powder is optimized, and the waterproof leakage repair service with insurance is more reliable.

Guangdong Meiyibang Building Materials] Grassroots open water, waterproof material water, maintenance time is not enough to soak in water, maintenance during the rain, these four situations will cause the waterproof layer to be white because of additional moisture. In addition, uneven brushing will also cause whitish local areas due to excessive moisture.

In humid and low temperature weather, the waterproof layer dries for a longer time, once the reserved drying time is not enough, the waterproof layer is affected by the moisture in the air, and the waterproof layer will easily turn white.

The local slight whitish has little effect on the quality of the waterproof layer; However, if there is severe whitting and strength problems, it is necessary to remove and reapply.

Summary. Dear, the exterior wall tiles are painted with transparent waterproof, and now the wall paintings are white, which is a normal phenomenon, and it can be restored to transparency after drying, so don't worry too much. However, it should be emphasized that before construction, it is necessary to ensure that the exterior wall is dry and protected from rain.

Secondly, the transparent waterproof adhesive is film-forming waterproof, which is only suitable for general exterior wall tiles, porcelain tiles, cultural bricks, etc., and is not suitable for glazed tiles and metal surfaces. The construction temperature should be controlled in the range of 5-35, and the weather will be cooler, so remember to avoid low-temperature construction in winter.
