Product information

Ronseal Anti Mould Paint resists moisture and steam and stops common mould growing on your walls or ceilings for up to six years. It’s ideal for kitchens, bathrooms, cellars and anywhere else that attracts mould.

  • Guarantee - Statutory
  • Suitable for use on Plaster
  • Surface Preparation - Make sure the room is above 10 °c and open doors and windows for extra ventilation. Put down dust sheets to protect anything you don’t want to get paint on. To prepare newly plastered walls - If you’ve recently plastered your walls or ceilings, they need to be left to dry for seven days. You will then need to seal the plaster before using the Anti Mould Paint. To prepare previously painted walls - If you already have mould, use mould killer to get rid of it. Don’t try and sand the mould off the wall otherwise you risk spreading the spores. Sand off any flaking paint so you have a smooth surface ready for painting.
  • Instructions for Use - Thoroughly stir the paint so the consistency is smooth. Pour the contents of the tin into a tray and coat your brush or roller. Wipe off any excess on the rim of the tray. Apply the first coat and wait four hours for it to dry. Apply the second coat and wait four hours for it to dry. If you can still see colour through the paint, apply more coats until the colour is no longer visible. Once you have applied the last coat, wait 24 hours before letting condensation build up in the room again.

Very reliable product.

Excellent. Covered the problem areas with a consistent thickness of paint. Only needed two coats as advertised. Great finish.

Product review

It does the job. Covers the mould and keeping that way

Maclad1888 - 5 / 5 - 03/02/2026

Brilliant product

Brilliant paint used in my bathroom ceiling to cover and kill mould.

red2410 - 5 / 5 - 01/02/2026

Good for damp patches

I bought this due to black spots on the bathroom ceiling. After treating, I used this paint, which dried so quickly, and so far no black spots have occurred.

Hope it does what it says on the tin

Have not used this Ronseal product before but painted on with good coverage and nice finish

Bugsysmum - 5 / 5 - 08/11/2025

Happy so far with this product

I used this product on an annoying mouldy area by the front door. The coverage was good & it was easy to apply & nice & smooth ready for the top colour. It hasn't been on long enough yet to comment on the resistance to mould, but I am hopeful

Zinsser

I bought this as an undercoat to cover an area that keeps getting black mould. Our house is 110 years old so I wanted something that would prevent the mould coming back after a few weeks. This stuff is great as am undercoat and the matte emulsion that I had bought for the walls went over the top beautifully. This size tin covered quite a small area - but that’s all I wanted it for. The paint itself is easy to use - not to runny - and one coat gave enough coverage to coat the mould on the wall that I wanted it to.

Stop Mold

I have to wait for next year if any mold appears. Paint is easy to apply

Morz - 5 / 5 - 01/08/2025

Moukd resistant paint

Easy application, good coverage, low odour, easy cleaning afterwards. Treated a small patch of wall behind the washer/dryer, looks much better and mould hasn't reappeared
