The bathroom is likely to suffer from condensation more than any other room in your property. This is because a large amount of moisture is produced when you shower or bathe. When water in the bathroom dries out, it evaporates into the air increasing the humidity level. If your bathroom is not well ventilated, this humid air lingers around preventing wet surfaces from drying out quickly.
Bathrooms contain surfaces which are particularly prone to condensation such as mirrors, single-glazed windows and metal window frames. This excess moisture is what causes mould infestations. Whilst small amounts of mould are harmless, if left untreated, prolonged exposure to mould can cause skin allergies and respiratory conditions to worsen.
If your bathroom is suffering from condensation, you will notice droplets of water on gloss painted window sills or black mould forming on the walls and ceilings.
In order to deal effectively with condensation in the bathroom, you must first reduce the amount of condensation and then tackle the mould.
This guide is split into two sections:
- How to Reduce Condensation in the Bathroom
- How to Remove Mould in the Bathroom
Reducing Condensation in the Bathroom
The best way to control and reduce condensation in bathrooms is with ventilation. Ventilators or extractor fans help reduce and eliminate surface condensation by exchanging stale air with fresh air. Ventilators stop musty air, mould growth and unwanted odours occurring in the bathroom. Bathroom ventilation is essential for good health, but it also plays a key role in improving the atmosphere of your whole home. This is because a well ventilated bathroom will reduce the amount of moist air circulating within the rest of your property.
Improving ventilation is an important step to preventing condensation and achieving a mould-free bathroom. Allow air to circulate throughout your property by keeping windows and doors open as much as possible. Cross-ventilating is the best method, opening windows at opposite corners of your home.
Ventilation systems are designed to be installed in areas that suffer from damp and mould-related issues such as bathrooms. Permagard’s very affordable Perma-vent Standard replaces moisture-laden air with fresh clean air, forcing contaminants to leave the home. Improved ventilation is the one of the most effective ways to control condensation and eliminate mould infestations in bathrooms.
Free ways to Avoid Condensation
Condensation can be controlled by you and for free. Simply changing your behaviour in the home can reduce the risk of condensation.
• Close the bathroom door when bathing/showering
• Open windows during and after bathing/showering to allow the moist air to escape
• Wipe down all surfaces, including bath units, windows sills and tiles to remove any excess moisture
• Avoid leaving wet towels on the floor as this will cause mould growth and create a musty damp smell
• Remove any mould you see immediately with mould wash concentrate to prevent further outbreaks
Other ways to avoid condensation:
Condensation is likely to occur if homes are under heated. Keep your homes above 15 Celsius at all times and this will help prevent condensation forming on outside walls.
Homes which suffer from severe condensation usually have poor insulation. It is important to make sure all of the rooms in the home are warm during the winter months, therefore increasing the temperature of cold surfaces.
Getting Rid of Mould in the Bathroom
A major mould infestation can cause damage to your home as well as your health. Bathrooms accumulate mould infestations more than other areas in the home as they are usually damp and poorly ventilated rooms.
Luckily, mould infestations are relatively easy to manage and treat providing you are proactive in your approach. Follow these steps:
A bathroom which welcomes constant light prevents mould infestations as mould cannot grow on well-lit areas. To improve the level of light in your bathroom, consider removing blinds and curtains which block out the sunlight and replace with opaque glass. If your bathroom doesn’t have a window, skylights or sky tube kits are recommended to increase the amount of natural light.
Wiping wet surfaces after use is a quick and easy way to prevent mould growth. Regularly clean the bath tub, the basin, the shower, the tiles and ceilings. Also, don't forget about the silicone corners around showers and baths. Mould tends to grow on wet surfaces and objects, therefore it is important that you clean surfaces underneath bathroom items including shampoo bottles, beauty products and soaps. Clean each product in turn and wipe dry to prevent mould growth.
Treat Tiles & affected surfaces with mould wash and anti-mould paint
You can remove mould from bathroom walls and ceilings by using an anti-mould wash and specially designed paint additives. These products combine to effectively kill off mould from problem areas and prevent it from coming back.
The mould wash concentrate is a fungicidal treatment designed to remove the mould from all bathroom surfaces. It works on tiles, as well as wood and painted surfaces. Start treatment by pre-washing the affected areas, removing any dirt and debris. Once the surface is clean and smooth, dilute the mould wash concentrate with water and wash the prepared surface with the liquid, using a sponge, brush or cloth. Wait for the liquid to dry thoroughly before applying another coating to badly soiled areas.
The next stage involves the anti-mould paint additive. This can be added to any paint type as well as tile grout and wallpaper paste. Simply add to your choice of paint and mix well. You can then paint over the affected areas in your choice of paint as per the manufacturer's instructions. The additive’s properties mean that the mould won’t return even in areas prone to condensation.
