Best patching plaster UK

Updated: October 2026

You want one amazon.co.uk listing for an indoor plaster repair, and the stars do not point at the same tub as the price per kilogram. The 4.8 cartridge has six reviews. The filler with 2,247 reviews is a shallow paste at £1.25. The cheapest plaster per listed kilogram is a powder you have to mix. This page matches each of the five kept listings to a job, and it says who should skip it. The full table, with scores, is the [indoor plaster comparison](/hub/paints-and-varnishes/plaster-indoor). Prices, stars and review counts are the amazon.co.uk figures from 21 October 2026. We did not lab-test the fillers. A qualifying purchase can earn a commission at no extra cost to you.

How this pick was chosen

The top pick is the highest amazon.co.uk star line among listings with at least 500 reviews. The best value is the lowest shelf price per listed kilogram in that same group. A 4.8 from six reviews can outscore both on a raw average and still fail the cut, because six opinions are not 2,000. Soudal is sold as 290 ml, so it stays off that kilogram line. The score starts from the star line times 20, which is why 4.6 becomes 92. The badge is withheld when the review count is under 500. If you have not yet decided between a nick, a patch and a whole wall, start with the buying guide.

Shallow repairs

Palace fine surface filler, model 68-4, is £1.25 for a 600 g ready-mixed tub, 4.6 from 2,247 reviews. All 50 texts stored for it are from the United Kingdom. The bullets keep deeper repairs to layers of no more than 3 mm, then sand and paint. UK reviewers use it on cracks and gaps around skirting and like the price. They also report leaking lids, a short date, a grey shade, and a cure that is hard to sand. The volume field prints 120 millilitres beside a 600 g unit count. Quote the 600 g title if you are comparing packs. This is the top pick for a shallow nick, a hairline that is already still, or a gap at a skirting. Skip it for a hole deeper than 3 mm in one go, a stated waterproof rating, or a knife in the box. A missing patch of skim is the powder or ready-mixed choice, if you will mix a small batch.

Patches you mix

Palace interior patching plaster, part 64-16, is £2.49. The title says 1.5 kg and the weight field says 1.42 kg. It is 4.5 from 571 reviews, with 50 UK texts in the file. The bullets describe a gypsum powder for interior walls and ceilings, mixed with water at 1:2.5, then sanded, painted or wallpapered. The listing does not give a single-coat depth and does not claim the powder is non-toxic. UK reviewers use it on ceiling holes and small losses of skim. Several say the mix went off in about 5 to 10 minutes. Palace's shop page says it sets within 2 hours. That is a set time, not an open-time promise. Some found it gritty or too hard to sand. Skip it if you want the lid back on tomorrow, if you are skimming a room, or if you need a stated non-toxic claim. One review says it is not a finish plaster.

Deeper paste, cartridge and kit

Sika SikaWall, model 480176, is £4.49 for 600 g, 4.4 from 5,464 reviews. The bullets allow plaster, brick and wood, up to 9 mm deep and 25 mm wide, indoors or outdoors if an outdoor repair is sealed with oil-based paint. The water-resistance field says not water resistant. UK reviews like a soft fill on dents and dislike a hard sand, sagging, smell, and tubs that looked half empty. The sheet says not to rework a depth over 9 mm in one pass, with about an hour between layers. Soudal Repair Express Plaster is a 290 ml cartridge at £9.12, 4.8 from 6 reviews. No gun is listed. The bullets say indoor walls and ceilings, sandable, shrink-free, and paintable in as little as 15 minutes. Treat 4.8 as a small sample, and buy it only if you already own a gun. The Polyfilla kit is £13.90 for a 396 g tube, a 3 inch scraper and a 120 grit block, 4.6 from 15 reviews, for holes up to 10 mm. Buy the kit only if you own neither a knife nor a block. Six or fifteen reviews do not outweigh two thousand on a shallow nick.

Common questions

Which listing has the strongest review sample?
SikaWall has the largest count, 4.4 from 5,464. Palace fine filler is next, 4.6 from 2,247, and it is the top pick because the badge uses the highest star line among listings with at least 500 reviews, not the biggest count alone. Palace powder has 571. The cartridge has 6 and the kit has 15, so their star lines are thin evidence.
Why is the £1.25 filler the top pick and not the 4.8 cartridge?
The cartridge is 4.8 from six reviews. The rule ignores that average until a listing has at least 500 reviews. Palace fine filler is 4.6 from 2,247 at £1.25, which is the highest star line inside that group. The cartridge can still be right for a small crack if you already own a gun. It is not the top pick on this page.
Which is the better price per kilogram?
Among listings with at least 500 reviews, Palace patching plaster is about £1.66 per listed kilogram at £2.49 for 1.5 kg. Palace fine filler is about £2.08 per kilogram at £1.25 for 600 g. SikaWall is about £7.48 per kilogram at £4.49 for 600 g. The cartridge is sold by the millilitre, so it is not forced onto that line. Waste from a fast set changes what you actually pay.
Can I use the fine filler on a deep hole?
Only in layers of no more than 3 mm, which is what the Palace bullets say, with each layer left to dry. A single plug deeper than that is outside the claim. For a hole up to 9 mm deep and 25 mm wide, SikaWall is the ready-mixed listing that prints that size. For up to 10 mm, the Polyfilla kit prints that size. None of those lines is a full-wall skim.
Is SikaWall waterproof?
The waterproof question on the listing is unanswered. The water-resistance field says not water resistant. Outdoor repairs are told to be sealed with an oil-based paint. Interior and exterior on the label is not a waterproof rating. Do not use it on a damp wall or in a permanently wet spot.
Does the Soudal tube include a gun?
No. Included components are one 290 ml cartridge. A gun is not listed. Soudal's own UK page says the filler can be applied with a gun or a trowel, which assumes you already have a tool. At £9.12, one of the two UK reviews in the file calls it not cheap. Budget for a gun if you do not own one.
