Buying Guide – What Do You Need to Know About Anti Mould Paint?

Above we have listed some of the best anti mould paints on the market. Each offers something different, so there should be one to suit any problem.

As important as your choice of paint is, you should also consider the method that you use for applying it. Using anti-mould paint right can have great results. If not used properly, it won’t be as effective.

There is a lot of misinformation out there about anti-mould paints, mainly stemming from people using them incorrectly. So this is what you need to know about the best anti mould paints and how they work.

Does Anti-Mould Paint Really Work?

Anti mould paint does really work. It does more than just cover up the problem. Different paints use different methods, but most contain an agent that stops mould from growing. This effectively kills the mould before it starts to form on surfaces.

It is important to keep something else in mind though. You need to treat the source of damp that is causing your mould as well. The best anti mould paint can stop it from growing, but you need to address why it is growing in the first place. You need to fix the problem that is causing your damp to stop it from coming back, as well as treating your wall to stop the growth of mould.  

Should You Paint Over Mould?

Before applying your anti mould paint you should clean the wall and either remove the mould or allow it to dry. This will treat the wall and prepare it to be coated in the paint. Painting straight over the top of the mould itself won’t get as good results as cleaning the mould that is already there. This is especially the case if the mould is still damp and wet.

How Do I Stop Mould from Coming Through Paint?

You can stop mould from coming through your paint by using an anti-mould paint and addressing the cause of mould. Usually, the cause is going to be a form of damp. The first step is to diagnose what type of damp you have, this will help you to choose the correct damp proofing solution. Whether it is penetrating damp, rising, or condensation, the source needs to be fixed first. Otherwise, your protection against mould won’t work as well, because mould will still be forming.

After that, you need to treat the surfaces that had the mould to prevent it from coming back again. This is where your anti mould paint comes in. Each of these uses a different method or biocide to prevent the mould from growing. Whichever you use, removing the mould and then protecting your wall is the most effective way to stop mould from coming through the paint.
