Top pick in this set
Zinsser Perma-White matt white, 2.5 litres, is the top pick because it has the strongest listing score among tins with at least 500 reviews: 4.7 from 521, at about £39.53, about £15.81 per litre. The title says self-priming interior matt, with a listed dry time of 1 hour and a full cure of 24 hours. One parents' bedroom painted in 2014 still showed only modest mould after about 11 years. That is a long report, not a promise for every wall.
The white is a cold, slightly blue white. One reviewer said it did not adhere over Zinsser Gardz, and bare drywall still needed a sealer and extra coats. Mould came back after a few months for someone who cleaned with vinegar first. Amazon's coverage field is 12.5 m² for the whole tin. Zinsser UK talks about 10 m² per litre per coat. The anti-mould paint buying guide keeps that split. It is a poor shortcut for a cubicle.
Best value on price per litre
The Ronseal white matt 2.5 litre tin is the best value in this set. At about £34.19 it works out at about £13.68 per litre, with 4.5 from 854 reviews. That is listing arithmetic from 19 October 2026, not a lab ranking. Mould stayed away for months, including a first winter, when the instructions were followed. A minority needed extra coats. Ronseal's six years are a brand condition if you leave the film as the top coat. They are not our finding.
A bullet says LARGE 25L SIZE. The size field is 2.5 litres. Tins arrived leaking, and one review title reports severe peeling after 9–12 months. A shower cubicle will leave paint unused. A ceiling plus the walls around it is where the price per litre makes sense.
The tin people already know
Ronseal's 750 ml white matt tin is about £19.21, about £25.61 per litre, with 4.5 from 4,020 reviews, the largest file here. One room stayed clear for about six years until it was refurbished. A wardrobe on an outside wall was still clear after three years. An en-suite ceiling lasted about 1.5 years, and mould returned after about eight weeks on a wet outside-wall larder.
Several reviews call it thin or runny, and two coats are how people finished the colour. One ceiling of about 6 m² needed more than the tin delivered. The attribute table says Spray and Exterior. The item is a liquid tin with a brush, and indoor/outdoor says Indoor. Do not buy it as an aerosol. Ceiling jobs are on anti-mould paint for bathrooms.
The £15.99 tins
Polar and Mould Solve both sat at about £15.99 for 500 ml, about £31.98 per litre, the joint highest price per litre in the set. The shelf price is what makes them look like the budget choice.
Polar has 4.4 from 1,670 reviews. Reviewers describe a thick film and a small shower or toilet cubicle in two coats. A water stain still showed after three coats in one review, and small patches returned after about a month on cold walls that stayed damp. Features say 5 year protection. A bullet says up to 10 years. Another calls it damp proof paint, while the title is anti-mould paint.
Mould Solve is 4.6 from 29 reviews, too small to set beside Ronseal's 4,020 or Zinsser's 521. It is the only listing here with a VOC figure, 25 g/l, and coverage of 4.6 m² for the tin. Use it only for a small patch where you want that VOC line.
Common questions
What is the best anti-mould paint in this set?
For a large humid job, the top pick is Zinsser Perma-White 2.5 litres, 4.7 from 521 reviews at about £39.53. That is the strongest star line among tins with at least 500 reviews. It is not a lab test. If you need the lowest price per litre, the Ronseal 2.5 litre tin at about £13.68 is the best value instead.
Is Zinsser better than Ronseal because 4.7 is higher than 4.5?
4.7 from 521 is a stronger star line than 4.5, and that is why Zinsser is the top pick. Ronseal's 750 ml tin has 4,020 reviews at 4.5, so you have a much larger sample of ordinary ceilings, including returns on wet walls. Higher stars on a smaller file are not a guarantee of eleven mould-free years. One Zinsser review reports modest mould only after about 11 years. One Ronseal review reports a return in about eight weeks on a wet larder wall.
Which tin is the best value?
The Ronseal 2.5 litre tin at about £34.19, about £13.68 per litre, with 4.5 from 854 reviews. The 750 ml Ronseal is about £25.61 per litre, and both 500 ml tins are about £31.98. Best value means that sum, not the lowest number on the shelf.
Can I trust Mould Solve's 4.6 from 29 reviews?
You can trust it as a small, early file. Reviewers liked two coats on tiny areas and several refused to judge the long term. You cannot set 29 reviews beside Ronseal's 4,020 or Zinsser's 521 and call the stars settled. The stated VOC of 25 g/l is the clearer reason to look at this tin.
Ronseal 750 ml or 2.5 litres?
Choose 750 ml for a ceiling, knowing Ronseal rates it at 4–5 m² with two coats and that one review lost coverage on about 6 m². Choose 2.5 litres when the area is closer to the maker's 13–16 m² with two coats, and when you want about £13.68 per litre rather than £25.61. The 2.5 litre listing's 25L bullet is wrong. The size field is 2.5 litres.
