Tips on How to keep Silicone Sealant Mould Free
All sealants will deteriorate over time, especially if there are given the right conditions.
The thing about bathrooms and showers is that generally speaking they present the perfect breeding ground for the mildew and bacteria that cause your sealant to go black, or become discoloured. These organisms especially thrive in warm, damp humid conditions, and once they get hold they just keep on multiplying.
Firstly, if you have silicone sealant that is already black and mouldy, and you don’t know if the sealant is top quality one, the likeliehood is (if it’s really bad) is that it’s probably a cheap one without an anti bacterial additive, or the sealant has not been cleaned regularly, or the location is not adequately aired.
If you have a problem with any of any one or more of the following: black mould on the tiles, the grout and/or the painted surfaces, the window coverings, the shower curtain etc, then in all probability there is a problem with ventilation. A common issue, is that people who open the window in the summer, stop doing this in the winter to save on losing heat which has cost them money in the first place to warm up the room. So what they do is keep the window shut! This means that you end up with a warm, damp humid room – the dream conditions for mildew, mould, and bacteria to have a field day, and can be sure that’s just what they’ll do!!
What’s the solution??
To start with have all the old silicone sealant removed by a reputable company like Glasgow’s ”Silicone King“, who replace all the silicone with a long lasting quality sealant.
You might think that is all you need to do, but you would be wrong!! After every shower you require to squeegee off all the standing water off all the tiles, shower door, and sealant, but be careful not to be too rough on the silicone sealant edges, as you may over time pull them from the surfaces to which they adhere. Get the family to make a habit of sqeegeeing the surfaces after every shower, it has the benefit of reducing the cleaning required!! Another tip after squeegeeing, is to use the towel you have just dried yourself with to get rid of any further moisture.
Silicone sealant also requires to be cleaned, just like your car, your kitchen etc. If you fail to clean the silicone sealant, then things that land on silicone like soap, shampoo, conditioner, and human body fat (this comes off the body when washing) will provide the conditions that mould, mildew and bacteria love to live off. Clean the silicone sealant with a good household cleaner. A good test to see if it’s clean is rub your finger along it when it’s wet – if it’s slippery, then it’s not clean – if it’s squeaky, then it’s clean!
Silicone Sealant and the correct type of Ventilation
Even if there is an opening window, you should have a humidistat fan fitted. A humidistat fan measures the amount of moisture in the air, and cuts in if it detects moisture above an unacceptable level. The humidistat fan will continue to run until such times as acceptable moisture levels have been reached. Ordinary fans on delayed time switches only cut in for a period of time, they do not take into account seasonal variations, whether the window is open or closed, nor do they know if the surfaces are clean and have been squeeged and dried off!!
So in short clean the silicone sealant regularly and fit a humidistat fan.
