How do you paint over mould?

Painting over mould might seem like a quick fix but you can bet your last biscuit that it’s going to keep coming back. Again, and again and again…

First of all, DON’T.

Painting over mould might seem like a quick fix but you can bet your last biscuit that it’s going to keep coming back. Again, and again and again. But don’t worry, correctly getting rid of mould is actually really simple.

We asked some of Leyland SDM’s storemanagers to put their heads together and share their top tips to for banishing mould for good, which is exactly what this blog post is about.

(If you’re after general DIY top tips – find them here.)

What happens if you paint over mould?

Yes, it’s possible to paint over mould but doing so won’t actually get rid of it. All our experts agree that it causes more problems in the long term. Untreated mould nearly always comes back and can spread across the affected area to other parts of the premises.

What’s more, painting onto mould can be very difficult. The mould itself acts as a barrier between the paint and the wall. So not only would the paint not apply properly, the finish would look shoddy too. Nobody wants shoddy walls.

Add this to the costs of having to repeatedly cough up for new paint when the mould grows back, and the negative effects of mould on your health, then it’s clear to see that our experts are right – it pays to do it properly.

Get the tools to take on mould!

Like any job, you need the right tools. Pick up some the appropriate supplies that will help you remove the mould. At Leyland SDM, we stock a number of mould cleaners and anti-mould paintsthat are designed with this specific job in mind.

IMPORTANT: While warm soapy water does an okay job removing mould from walls, anti-mould sprays are designed to kill mould instantly AND help protect your surfaces against mould coming back.

We also recommend picking up a disposable dust maskand some rubber gloves. Mould spores can cause allergic reactions if touched or inhaled so ensure you are protecting yourself.

Finally, you’ll want to pick up a tin of quality anti-mould paint.

Anti-mould paint is formulated with acrylic resin to create a water-resistant barrier on your walls. This prevents moisture soaking through the paint and into the surface where mould can grow.

Leyland SDM’s quick guide to removing mould

SPRAY – Apply your mould spray liberally to the affected area and leave it on there for as long as it says on the bottle.

WIPE – Thoroughly wipe down the area with a cloth, until all of the mould has been removed. Our experts recommend using a j-cloth for this.

Repeat these steps until all the mould is gone.

WASH – With a clean cloth and water, wash and wipe down the area to remove any residue that may have been left behind. Now leave it dry completely before painting.

PAINT – Apply a couple of coats of your anti-mould paint. Make sure each coat is fully dry before adding the next.

How to stop mould from coming back

You don’t need to spend lots of money on dehumidifiers, or repaint your whole place with anti-mould paint. There are some quick, easy and cost-effective ways to deter mould.

One of the easiest ways to prevent mould is to ventilate your rooms are properly. Try keeping internal doors open to allow air to circulate, or let in some fresh air for 10-15 minutes each morning.

If you live in a property that has poor, consider a moisture absorber. Moisture absorbers are fantastic bits of kit that will help remove water vapour from the air, reducing the chances of mould.
