How to get rid of mold in the house?

If mold is noticeable in your home, it is essential that you remove it and find the source of the moisture. Mold grows best in dark, damp, and cold places like kitchen cupboards, bathrooms, garden sheds, and such. Let’s see how to get rid of mold and mildew.

Finding the moisture area:

The first step in fixing a damp problem is identifying its source. After locating and addressing the cause of the mold, it is possible to eliminate it using an antifungal solution.

Scrub it down:

Mold and mildew can be removed in a number of ways, but one of the best and most obvious is to simply scrub it away.

Soap water, baking soda, vinegar, or another bleaching agent can be used to first soften the fungal growth. The affected area should also be cleaned regularly with a wet sponge or cloth.

Scrubbing the mouldy surface is an effective method of removing the fungal growth and making the stains easier to remove.

Maintaining an optimum level of humidity:

Maintain a relative humidity level in your home that is no higher than 50% at all times, even if it is as low as possible.

You can help keep the level at a manageable level by using an air conditioner or a dehumidifier. At a store that specializes in home improvements, you can get a meter to measure the amount of humidity in your house.

You should check the humidity more frequently than once a day because it fluctuates throughout the day.

Maintaining proper ventilation and sunlight:

Allow fresh air and sunlight in by throwing open the windows and doors. Light from the sun not only terminates molds and mildews but also stops more from growing, making it a potentially useful home remedy.

Tiling and grouting or painting:

Another effective method for preventing any kind of fungal infestation is to thoroughly clean the tiles and then seal the grout.

Mold and mildew can quickly spread through a home if certain conditions are met, including the presence of unfinished kitchen tiles and cracked bathroom floors.

An additional weapon against mold is antifungal paint, which can be applied to surfaces.

Final thoughts

Mildew and mold are not possible to eliminate with Kilz. If you have mold or mildew on your wall, you can cover it with Kilz. All of the stains can be effectively concealed in this manner. But on the other hand, it is not a primer or paint that actively terminate mold. So that it won’t be effective.
