If there is mildew on the wall, can it be repaired with latex paint?

Yes, with latex paint.

Brush directly on the moldy spots, apply it lightly, apply it again when it is dry, dry it, and smooth it out. In front of my house, there was a piece of wall skin on the balcony that fell off and used sunflowers.

Moldy Walls – There are several possible causes of moldy walls.

1. The wall is not dry during the decoration, so it can only be shoveled off and redone after the spring.

2. Next door to the wall is the bathroom, the wall waterproofing is not good, and the waterproofing of the bathroom is redone after being wet.

If there are uneven places, it is still necessary to polish off the paint surface to expose the putty layer, and then use putty to level and then make primer and topcoat in turn.

Dehumidification by air conditioning, enhanced ventilation and air convection, bleach spray (use with caution on colored walls), raising room temperature, and removing and repainting in local areas are all good methods, and sometimes a combination of these methods can be used. However, these methods can only treat the symptoms but not the root cause, because the brand of the paint determines the performance of the coating, and if you return to Nantian again next year, this phenomenon will be repeated.

Is the latex paint wall moldy, is it newly painted or is there a latex paint wall with a considerable history?

There is a liquid anti-mildew agent, you first have to brush the mold on the wall, brush it with soapy water + brush, brush off all the mold spots, and then do anti-mildew treatment. Don't look for toxic antifungal agents, because antifungal is not sterilization!

Finally, it is enough to brush the paint again and plant the anti-mold agent on the bottom layer of the paint.

Reason: This is caused by the cold of the wall, which is commonly known as the cold penetration, but it is actually the reason why the wall insulation is not done well. The wall insulation is not done well, it is a problem of building quality, in the north, a very important part of housing construction is the external wall insulation.

In general, measures are taken in the north to carry out thermal insulation treatment, and the main method is to sandwich insulation materials in the wall. Block the conduction of heat by the wall.

If the wall insulation is not done well, it will lead to cold penetration, and the phenomenon of cold penetration is mold, blackening, and hair growth on the indoor wall. The reason is that the indoor air is warm, the water vapor saturation is high, and the wall is not well insulated, so the wall is cold, and the water vapor will crystallize into water droplets on the wall, and the wall will become moldy and hairy when it is wet.

To avoid the hair of the wall, the main thing is to do a good job of wall insulation. But sometimes under the current technical conditions in our country, it is impossible to deal with it very, very well, if the indoor humidity is too large, even if the wall insulation meets the requirements, there will still be moldy and hairy phenomenon.

Therefore, if there is no serious problem with wall insulation, your best way is to open more windows to ventilate and reduce the indoor water vapor content, especially in the newly renovated house, the water vapor is particularly large, and you should let the air for a period of time to remove the moisture.

In short, the principle is one: do a good job of heat preservation; 2. Reduce indoor humidity; Three: more ventilation indoors.

1. Remove the moldy wall, be sure to thoroughly expose the cement substrate. Because mold grows back from the bottom.

2. Clean with a brush dipped in 84 disinfectant, brush hard, brush thoroughly, let 84 invade the wall, and completely sterilize.

3. Wash with clean water.

4. Dry, be sure to dry completely.

5. There are many kinds of sealing agents on the market, so you must choose one with good permeability and sealing. Identification method, try to brush a piece, watering after drying, if the water flow does not penetrate, it means that the closure is good, if it leaves an obvious watermark, it means that the emulsion used is sticky when exposed to water, and the effect is not good.

6. Batch putty, paint. Don't be superstitious about the so-called anti-mildew effect of latex paint, it is useless at all, it is not a concept.
