The best fillers, compared.
Top pick: Polycell multi-purpose Polyfilla, 330 g tube – Highest score: 330 g ready-mixed tube at about £3.49, 4.6 from 14,595 reviews. Hard to squeeze, skins in the tube, and no depth on the listing. Best value: Sika SikaWall – Best filler per pound among tubs with several thousand reviews: 600 g at about £4.49, 4.4 from 5,464, listed to 9 mm by 25 mm. Not water resistant, and hard when thick. Updated 22 October 2026.
A filler, for a UK decorator, is the paste or powder you press into a static crack, screw hole or shallow dent so you can sand and paint. It is not a flexible bead for a joint that moves. You tell a suitable pack by the depth and width on the label, whether it says interior or exterior, and the surface you are filling. Fine-surface paste is for hairline cracks. Ready-mixed paste covers screw holes and modest cracks. Lightweight paste is for overhead work. Powder is mixed with water. Wood filler is separate if you may stain the timber. Those checks are in the [filler buying guide](/hub/fillers-adhesives-and-sprays/filler/sub/filler-buying-guide). A cure you can sand, and a lid that seals, matter as much as pack size. Ready-mixed paste skins if air gets into the tub. A thick layer can set too hard to sand by hand. Open a hairline slightly, leave a damp crack until it is dry, and sand as little as you can. Gypsum dust from plaster is construction dust.

Question 1 of 2
How big is the damage?
The Polycell multi-purpose Polyfilla tube, at about £3.49, is a ready-mixed white 330 g paste you squeeze onto a dry crack or screw hole. It is 4.6 from 14,595 amazon.co.uk reviews, and the first 50 texts describe small drilled holes, cracks and a finish that sands and takes paint on those small jobs. Several reviewers say it dries quickly to a solid fill, and repeat buyers treat it as the same tube they have used for years. The listing says it will not shrink or crack, which is a claim rather than a measured result, and the page does not state a maximum depth. The tube is hard to squeeze, and the paste skins or hardens inside even with the lid tight, so some people treat it as a single use. It does not always dry fully white, and one review says you should prime it or the filler shows through the paint. With that review count and the shelf price on 19 October 2026, it is the top pick in this set for a small repair, while a deep chase sits outside anything the listing specifies.
Pros
Cons
Best for: You want a small ready-mixed tube for dry screw holes and modest cracks, and you can squeeze a stiff tube.
Less suitable: You need a stated depth, a tub you will reopen for months, or a fill you will leave unprimed under a pale paint.
Specifications
Common questions
Is this Polyfilla ready mixed?
Yes. The listing says it is ready mixed, with a smooth creamy consistency, and that you should make sure the surface and the crack are dry before applying.
How big is the tube?
The unit count is 330 g. The shelf price in this file is about £3.49. Included components are the tube only.
Does the listing say it will not shrink?
Yes. A bullet says it will not shrink or crack. That is a listing claim. Reviews in the file also say the paste can harden inside the tube.
Palace fine surface filler is listed at about £1.25 as a ready-mixed white paste for shallow cracks and fine nicks, with deeper repairs in layers of no more than 3 mm. It is 4.6 from 2,247 amazon.co.uk reviews, and that same star line, model 68-4 and review text also sit on the Langlow listing B0G51LQMSN, so this is not a separate sample of 2,247. Reviewers praise the price, easy spreading and sanding on fine cracks, skirting, door gaps, walls and ceilings. Lids arrive open, split or leaking, the paste goes hard once air gets in, and some say the cure is grey rather than white. Left thick it is hard and dusty to sand, and one review says it was still shrinking after a few days. The water-resistance field says water resistant, while the use line is interior. At about £1.25 it is a cheap fine-surface tub when you stay at 3 mm a layer. It is not the best value in this set, because the review file is shared.
Pros
Cons
Best for: You are feathering hairline cracks and shallow nicks indoors, in layers of 3 mm or less.
Less suitable: You need a deep hole filled in one go, or you are treating this star rating as a sample independent of the Langlow page.
Specifications
Common questions
How thick can each layer be?
The listing says that for deeper repairs you apply layers of no more than 3 mm and let each layer dry. It is for shallow cracks and fine nicks.
Is it for outside walls?
The bullets describe interior surfaces, including plasterwork, render, skirting and timber-based structures. The water-resistance field says water resistant.
Are the 2,247 reviews only for this tub?
No. The same star line, model 68-4 and review text also appear on the Langlow pack listing B0G51LQMSN.
The Langlow title says a pack of two 600 g fine-surface tubes at about £2.50, while the brand field says Palace, the item type name says Langlow Fine Surface Filler 600 g, model 68-4, and included components say one filler. Item weight is 650 g against a 1,200 g unit count. It is 4.6 from 2,247 amazon.co.uk reviews, the same figure and the same review text as Palace B07XGMLGRX, and one review mentions £1.25, which matches the Palace shelf price. Those shared texts praise easy spreading on fine cracks and also describe split tubs, a grey cure, hard sanding and shrinkage. Pack language in the reviews is not proof this ASIN shipped two tubs. There is no 3 mm layer line on this listing, unlike the Palace page. It is a conflicting pack page that borrows another ASIN's reviews, not a second tested filler.
Pros
Cons
Best for: You already understand this is the same model 68-4 review file, and you will check how many tubs arrive.
Less suitable: You want a confirmed two-pack, or a star rating that belongs only to this ASIN.
Specifications
Common questions
Is this a two-pack?
The title says pack of 2. Included components say 1 x fine surface filler. Number of pieces is 2 and item package quantity is 1. Item weight is 650 g against a 1,200 g unit count.
Which brand is on the listing?
The brand field says Palace. The item type name says Langlow Fine Surface Filler 600 g, model 68-4, made by Palace Chemicals.
Is the star rating a separate sample?
No. It is 4.6 from 2,247, the same figure and the same review text as Palace B07XGMLGRX. Reviews mention about £1.25.
This kit is listed at about £13.90 as a 396 g Polycell Polyfilla tube, a 3 inch Decex scraper and a flexible 120 grit sanding block. The brand field says Decex. The listing says it fills holes up to 10 mm, indoors and outdoors, on plaster, masonry, concrete and brickwork, and that it is surface-dry in 1 to 2 hours. It is 4.6 from 15 amazon.co.uk reviews. Six United Kingdom reviews are in the file, and they are short: useful for cracks and crevices, easy, and as described. None of those six describes a repeated defect. A 4.6 on 15 reviews is not the same evidence as the 14,595-review Polycell tube at about £3.49, and you are paying for the scraper and block as well as the paste. It is a starter kit if you do not already own a scraper, and it is not the top pick.
Pros
Cons
Best for: You want one box with paste, a scraper and a sanding block for holes the listing puts at up to 10 mm.
Less suitable: You already own a scraper, or you are choosing on a 4.6 that rests on 15 reviews.
Specifications
Common questions
What is in the box?
One Polycell Polyfilla 396 g tube, one 3 inch scraper and one flexible 120 grit sanding block. The brand field says Decex.
Can you use it outside?
The listing says it fills holes up to 10 mm deep, indoors and outdoors, on plaster, masonry, concrete and brickwork.
How many reviews are there?
The listing shows 4.6 from 15 reviews. Six UK reviews are in the saved listing, and they are short.
Ronseal smooth finish filler is a white 600 g tub at about £7.24, described for small last-minute interior repairs on plaster, stone, concrete and wood. It is 4.5 from 3,894 amazon.co.uk reviews. In the first 50 texts, people spread it on small gaps and holes, and some say it sands with less effort than other fillers. Reviewers mention a small plastic triangle spreader in the pot, which helps a hairline and is useless on a larger hole. The title is one 600 g tub, while the number-of-items field says 12 and the number of packs says 2. Applied thickly it shrinks a little, sets so hard that hand sanding is difficult, and does not always dry white. It is wet enough to fall off a spatula, awkward on a ceiling, and the lid can arrive broken or fail to click shut, so the paste dries in the tub within months. It suits a modest interior hole when you can ignore the conflicting piece-count fields and keep the layer thin.
Pros
Cons
Best for: You have a small interior crack or hole on plaster, stone, concrete or wood, and you will keep the layer thin.
Less suitable: You are filling a ceiling chase, or you need the listing to confirm one tub rather than 12 items.
Specifications
Common questions
Where can you use this Ronseal tub?
The bullets say small, last-minute interior repairs on plaster, stone, concrete and wood.
Is the piece count one tub?
The title is 600 g. The number-of-items field says 12 and the number of packs says 2. Those fields conflict.
Does the listing say you can paint it?
The bullets do not say. The item type name calls it a ready-mix wall filler. Reviews describe painting after sanding.
Sika One Strike is listed at about £13.20 as a white 2.5 litre tub, while the size field also says 875 g and the weight field says 900 g. It is 4.5 from 937 amazon.co.uk reviews. Reviewers describe a very light, whipped paste that spreads easily, fills chases and ceiling work without the sag they report on heavier filler, and sands more readily than a dense ready-mixed paste. One reviewer sanded after about three hours. The listing itself does not state a maximum depth, so a deep fill is a review story rather than a printed limit. The repeated complaint is that a deep hole stays finger-nail soft under a dry crust, sometimes for weeks, and sanding can roll the surface into small balls. One review says the tub was under-filled against the 2.5 litre claim, and a reviewer who read the tub says it is not for structural use. It is the lightweight option in this set when you can wait for a deep fill to go hard.
Pros
Cons
Best for: You want a lightweight paste for overhead or chase work, and you will check that a deep fill has gone hard before you paint.
Less suitable: You need a hard structural fill, or you are buying on the 2.5 litre figure without checking the weight fields.
Specifications
Common questions
How much is in the tub?
The title says 2.5 litre. The size field also says 875 g, and the item weight is 900 g. Those figures are all on the listing.
Does the listing state a maximum depth?
No. The scraped bullets only name One Strike filler, 2.5 litre and Everbuild. Depth is not on this listing.
What do the reviews say about weight?
Reviewers describe a very light, whipped paste. Some deep fills stayed soft. That is review text, not a depth rating.
The Sika SikaWall all-purpose filler, at about £4.49, is a ready-mixed white 600 g paste the listing limits to 9 mm deep and 25 mm wide. It is 4.4 from 5,464 amazon.co.uk reviews. In the first 50 texts, people use it on plaster dents, interior masonry, wood window frames and concrete ledges, and they say a small repair dries and sands if you shape it before it cures. The bullets say interior and exterior, and they tell you to seal outdoor fixes with an oil-based paint, while the water-resistance field says not water resistant. Left thick, it sets too hard for hand sanding, and some reviewers say even an electric sander struggles. It is sticky, wet and heavy, so it sags, and it goes off quickly in the tub if the lid is not airtight. One reviewer would not use it outdoors because the dry finish looked transparent. At this price, with a stated depth and several thousand reviews, it is the best value in this set when you stay inside 9 mm and paint an outdoor patch with oil-based paint.
Pros
Cons
Best for: You are filling a dry crack or hole within 9 mm by 25 mm, and you will shape it before it sets hard.
Less suitable: You want a lightweight paste that sands easily when thick, or a filler you can leave outdoors without oil-based paint.
Specifications
Common questions
How deep can this SikaWall tub go?
The listing says gaps and cracks up to 9 mm deep and 25 mm wide. It is ready mixed and applied from the tub.
Can you use it outside?
The listing says interior and exterior, and says to seal outdoor fixes with an oil-based paint. The water-resistance field says not water resistant.
Can you paint it?
The listing says that when it is dry you can cover it with most paints, wood stains or wallpapers, and that it is sandable.
The Sinto hole and crack filler is a ready-to-use white 5 kg pail at about £16.33. A bullet says repairs up to 1 cm, zero shrinkage and no cracking, with a full cure of 12 hours. It is 4.4 from 768 amazon.co.uk reviews. Of the first 50 texts, 23 are United Kingdom reviews: they call it easy to spread and sand, and one painter used it on walls, a ceiling and woodwork. Those same UK texts also report shrink, cracks and sag, lumps that made about half a tub unusable, and a pail that arrived open and spilled. The material field says silicone and the compatible-material field says plastic, while the bullets describe a filler paste, so those lines conflict. It is a large pail for a bigger area of static cracks if you accept that the zero-shrinkage bullet is disputed in the UK reviews, and if 1 cm is enough.
Pros
Cons
Best for: You have a larger area of static cracks within the stated 1 cm, and you will add another layer if it shrinks.
Less suitable: You want a small tube, or you are buying because the bullet says zero shrinkage.
Specifications
Common questions
How deep does the Sinto bullet go?
The listing says repairs up to 1 cm deep, with zero shrinkage and no cracking stated as a bullet. UK reviews in the file also report shrink, cracks and sag.
How long is the full cure on the listing?
The full cure time field says 12 hours. It is a ready-to-use paste in a pail.
What material does the listing name?
The material field says silicone and the compatible-material field says plastic. The bullets describe a hole and crack filler paste. Those lines conflict.
The Mollor kit is 150 g of white water-based wood putty at about £9.99, with a scraper, sandpaper and gloves listed in the bullets. The title says stainable. It is 4.3 from 211 amazon.co.uk reviews, and 16 United Kingdom texts were used from the saved listing. Those reviews say it is easy to apply and sand, and that it did the job on wood for several people. They also say it is too thin: it ran down a vertical hole and had barely set after 8 hours. It dries white, not a natural timber colour, and one review says paint did not cover it well. The listing itself warns that large areas may sink because it is water-based, and the special-features line says non-toxic, which is a listing word rather than a test. It is a small white wood-putty kit when you will paint rather than stain, and when the hole is not a deep vertical pocket.
Pros
Cons
Best for: You are filling a small defect in furniture or a door frame you will paint, and you can wait for a thin water-based putty to dry.
Less suitable: You want a stainable timber colour, a plaster skim, or a putty that stays in a vertical hole.
Specifications
Common questions
What is in the kit?
The bullets list wood putty, a scraper, sandpaper and gloves. The included-components field also names a nozzle extender and a wall repair patch.
Is it stainable?
The title says stainable. The colour is white. UK reviews say it is white rather than a natural wood colour, and one says paint did not cover it well.
Will a large fill sink?
The listing says that because it is water-based, large areas may sink after drying, and that you can apply another layer once it is dry.
Nine amazon.co.uk filler listings were scored on a 0–100 scale. Amazon evidence is 30 points, from the star rating, with a deduction when the count is small or when two ASINs share one review block. Listing fit is 35 points. A stated depth, a clear interior or exterior line, and a pack that matches the title score higher. Contradictory brand, weight, piece-count or material lines are deducted. Review outcome is 20 points. Reviews that describe a filled crack or screw hole score higher than a file that repeats a tub that will not sand, a soft core, or a lid that arrives open. Value is 15 points, from the shelf price in GBP against a pack a review says will do a small job. The lowest price does not score when the review file is shared or the depth is only a fine-surface layer. The highest score is the top pick. The best filler per pound among tubs with several thousand reviews, after hardness and the exterior paint line are already noted, is the best value. One of each. A 4.6 on 15 reviews is not scored as the best household filler. The about £1.25 tub is not scored as best value when its review file is shared with another ASIN. A bullet that says the paste will not shrink or crack is not scored as a measured result. Prices are the amazon.co.uk shelf prices on 19 October 2026. This is not a laboratory test.

Match the printed depth, the interior or exterior line, and the surface to a static crack you will sand and paint. A will-not-shrink bullet is a listing claim. A shared review file is one sample.
A filler is the paste or powder you press into a static crack, screw hole or shallow dent so you can sand and paint. Caulk is for a gap that moves. Expanding foam fills a cavity. Powder filler is mixed with water. None of the tubs and tubes in this table is a powder. Coat depth on a powder sheet, and when a lightweight paste is the overhead choice, are set out in [ready-mixed or powder filler](/hub/fillers-adhesives-and-sprays/filler/sub/filler-ready-mixed-or-powder).
A fine-surface tub is the wrong buy for a deep chase. Palace limits deeper repairs to layers of no more than 3 mm. SikaWall states 9 mm deep and 25 mm wide. One Strike's listing states no depth. The 75 mm figure is on the data sheet, and some reviews describe a soft core.
Painting while the core is soft, or believing a will-not-shrink bullet that reviews contradict, leaves a crack you have to fill again. Sinto's bullet says zero shrinkage. UK reviews on that pail report shrink, cracks and sag.
Palace and the Langlow pack-of-2 title share one 4.6 from 2,247 block and model 68-4. That is not two samples. A loose lid skins ready-mixed paste, so the rest of the tub is lost.
Read the depth and width on the listing before the pack size. Palace says layers of no more than 3 mm. SikaWall says up to 9 mm deep and 25 mm wide. The kit listing says holes up to 10 mm. Sinto's bullet says repairs up to 1 cm. One Strike's amazon.co.uk listing states no depth. The data sheet says up to 75 mm in one application and excludes plastic and metal. That sheet figure was not proved by the reviews, and some reviews describe a soft core.
A cure you can sand matters as much as the tub size. UK reviews on SikaWall, Ronseal and Palace include fills that were too hard to sand once a thick layer had cured. Ready-mixed paste skins if the lid does not seal. Score the review file before the shelf price. Polycell 330 g is 4.6 from 14,595 reviews at about £3.49. The scraper kit is 4.6 from 15 reviews at about £13.90.
Three typical situations, each with a recommendation from this comparison.
You want a small ready-mixed tube for dry screw holes and modest cracks. Polycell multi-purpose Polyfilla is the top pick: 330 g at about £3.49, 4.6 from 14,595 reviews. Reviewers sand and paint small jobs. The tube is stiff, the paste skins inside, and no maximum depth is printed.
You are skimming a room of hairline cracks, rather than buying a 5 kg pail. Palace fine surface filler states layers of no more than 3 mm, at about £1.25, for interior nicks. The 4.6 from 2,247 reviews is shared with the Langlow listing, so it is not the best value in this set. Keep each layer thin.
You are filling timber you may stain. The Mollor kit is 150 g of white wood putty at about £9.99, 4.3 from 211 reviews, with a scraper, sandpaper and gloves. The title says stainable. UK reviews say it dries white and can run on a vertical hole. Test a patch. Do not fill gaps between floorboards with wall paste.
The top pick is the Polycell multi-purpose Polyfilla 330 g tube at about £3.49. It is 4.6 from 14,595 amazon.co.uk reviews. Reviewers use it on screw holes, cracks and drilled holes, and small jobs sand and take paint. The tube is hard to squeeze, the paste skins inside, and the listing states no maximum depth. The best value is Sika SikaWall, 600 g at about £4.49, 4.4 from 5,464 reviews, listed to 9 mm deep and 25 mm wide. The listing says interior and exterior if you seal outdoor fixes with oil-based paint. It is not water resistant, and a thick fill sets too hard to sand. The Palace tub at about £1.25 is not best value here, because its 2,247-review file is shared with the Langlow listing. A 4.6 from 15 reviews on the scraper kit is not scored as the best household filler. This is not a laboratory test.
Polycell multi-purpose Polyfilla, 330 g tube
Highest score: 330 g ready-mixed tube at about £3.49, 4.6 from 14,595 reviews. Hard to squeeze, skins in the tube, and no depth on the listing.
Sika SikaWall
Best filler per pound among tubs with several thousand reviews: 600 g at about £4.49, 4.4 from 5,464, listed to 9 mm by 25 mm. Not water resistant, and hard when thick.
