Frequently Asked Questions (FAQs)

How can I prevent yellow stains on my bathroom wall?

If you have determined that the issue is the ventilation and moisture in your bathroom, it is easy to fix.

You should install bath fans that are sized according to the volume of the bathroom so that they can make a minimum of 8 air exchanges per hour.

The fans should run while you bathe and for 30 minutes afterward to clear the moisture and humidity.

What causes bathroom walls to sweat?

Bathroom sweat is the condensation in the bathroom from water droplets forming on the windows, walls, and other surfaces when you bathe and from when the warm, damp air in the bathroom is cooled by these cold surfaces.

Warm air holds more moisture, and this results in heavier condensation, which is known as the ‘sweat’.

How do you stop condensation on walls?

To prevent condensation, it is important to open the bathroom windows and turn on your bathroom fans. Wet surfaces attract moisture, so you should wipe them to get rid of the excess water.

Also, vinegar is useful as a preventative agent to prevent mold, bacteria, and mildew from growing on surfaces.

You can spray the vinegar solution over the tiles and bathroom surfaces after taking a bath to keep your bathroom well-maintained and clean.
