The best structural pastes, compared.
Top pick: Vigorder Modelling Paste Best value: Mont Marte Modelling Paste 500 ml – About £13.05 for 500 ml, 4.6 from 1,159 reviews, the lowest white-tub price, with UK texts split on thickness. Updated October 2026.
Structural paste on amazon.co.uk is the thick acrylic medium UK shops also call modelling paste or texture paste. You knife it on so a painting stands up in relief. Quality is the body you need, the support the listing names, and whether you will paint the dry film. A title that says texture can be smooth white, flexible white, coarse sand, or metallic gold. Treat a wall as in scope only when that listing names walls. The [structural paste buying guide](/hub/painting-supplies/structural-paste/sub/structural-paste-buying-guide) orders those checks. They are not wall filler, not a wood-repair epoxy, and not a clear gel.

Question 1 of 2
What do you want the paste to do?
The Vigorder listing is a white acrylic modelling paste at £15.99, sold as high viscosity that holds its shape, with canvas, wood panels, and cardstock named as supports. The title says 850 g, the item weight says 800 g, and the volume field says 600 ml, and this extract does not reconcile those three lines. The star line is 5.0 from 1 review, and that single UK text says the tub is a useful size for canvas and mixed-media layers. A spec field says crack resistant, which is a listing claim rather than a test, and there is no water-resistance field. One review cannot tell you whether the body stays thick once the jar is open. You would be comparing a low shelf price against a size you still have to check on the live page. The 5.0 star line is not the top pick.
Pros
Cons
Best for: Someone comparing a low shelf price who will check the live size before buying.
Less suitable: A buyer who needs a large UK review sample or a single agreed volume.
Specifications
Common questions
Is the Vigorder tub 850 g or 600 ml?
The title says 850 g, the item weight says 800 g, and the volume field says 600 ml. The extract does not reconcile them.
How many reviews are on the listing?
The star line is 5.0 from 1 review. That review is from the United Kingdom and describes canvas and mixed-media layers.
Does the listing say it is waterproof?
No water-resistance field is printed. A spec field says crack resistant, which is a claim, not a test.
The Marabu tin is 100 ml of metallic gold structural paste, model 12020050084, at £10.30, and the listing calls it a creamy pastose paste for stretcher frames, wood, MDF, paper, and metal. The spec says water resistant and a bullet says weatherproof, with no UK outdoor test in the extract. The star line is 4.8 from 6 reviews. The one text in the extract is from Germany and praises the gold tone; none is labelled United Kingdom. It is mixable on the bullet, which does not say the gold stays unchanged if you add colour. At 100 ml it is a stencil tin, not a tub for building white relief across a canvas. The low shelf price is the gold effect, not a cheaper version of the 500 ml white pastes. The 4.8 star line is not the top pick.
Pros
Cons
Best for: A small metallic gold stencil paste, not a tub of white relief.
Less suitable: Building texture across a canvas, or anyone who needs a white ground.
Specifications
Common questions
Will this paint a white textured canvas?
It is 100 ml of metallic gold paste. It is not a 500 ml white modelling paste.
What does the listing claim about water?
The spec says water resistant. The bullet says weatherproof. There is no UK outdoor test in the extract.
Where are the written reviews from?
The star line is 4.8 from 6 reviews. The one text in the extract is from Germany and praises the gold tone. None is labelled United Kingdom.
The Liquitex jar is model 8916, 473 ml of professional flexible modelling paste, at £21.20, and the listing says it dries more slowly than other modelling pastes to a hard yet flexible film. The cure field says 24 hours. UK texts on thick work mention 48 hours in a mould and about 72 hours on larger pieces, so the field is not the thick-film wait. The star line is 4.7 from 881 reviews, and many UK texts use it for texture, knives, flexible moulds, canvas, and bottles. Two UK texts say the jar arrived already opened. A bullet says non-toxic and ASTM D4236, which is a US art-materials standard; this extract does not print a biocide warning. Coverage is given as 5–6 sq ft per 0.5 L. You are paying for a named flexible paste if you can wait out a thick layer and check the seal on arrival. It is the top pick in this folder. It is not the hard Liquitex modelling paste sold for rigid supports.
Pros
Cons
Best for: A named flexible paste when you can wait out a thick layer and check the seal on arrival.
Less suitable: A coarse-sand texture, a 100 ml gold effect, or a buyer who needs a same-day dry film.
Specifications
Common questions
Is this the hard Liquitex modelling paste?
The listing is model 8916, professional flexible modeling paste, 473 ml. It says the film is hard yet flexible and dries more slowly than other modelling pastes.
How long do UK reviewers wait?
The cure field says 24 hours. UK texts on thick work mention 48 hours in a mould and about 72 hours on larger pieces.
What does the listing say about safety?
A bullet says non-toxic and ASTM D4236. ASTM D4236 is a US art-materials standard. This amazon extract does not print a biocide warning.
The Kreul Solo Goya tin is 250 ml of coarse-sand structural paste, model 85605, at £16.86, and it is meant to dry white, matt, and opaque with a sand-like surface. The dry-time field says 6 hours, and the bullets say you can dye it with acrylic and paint over it with acrylic or oil. The star line is 4.7 from 92 reviews, but the eight texts in the extract are not labelled United Kingdom. One German text says grains can fall off when you paint over them. The item weight is 125 g against a 250 ml volume, which is a light tin for the millilitres printed. This is the coarse-sand row, so a smooth white peak is a different product.
Pros
Cons
Best for: A small tin when the texture you want is coarse sand, not a smooth peak.
Less suitable: A smooth white ground or a buyer who only trusts UK-labelled reviews.
Specifications
Common questions
Is this a smooth modelling paste?
No. The listing calls it a coarse-sand structural paste with a sand-like surface.
Are the written reviews from the UK?
The star line is 4.7 from 92 reviews. The eight texts in the extract are not labelled United Kingdom. One German text says grains can fall off when you paint over them.
What dry time does the listing print?
The dry-time field says 6 hours.
The Mont Marte tub is 500 ml of white modelling paste, model MMAR23790, at £13.05 in this extract, and UK buyers use it for knife texture on canvas and, in one text, on scale-model houses. The star line is 4.6 from 1,159 amazon.co.uk reviews, the largest file in this set. Some of those UK texts say the paste holds peaks and builds in layers. Others say it is too thin for a dense shape on canvas, so the same tub is not a settled thickness. There is no dry-time field; one UK text says the directions claim about 30 minutes and a thin coat was still wet after 8 hours. One UK text also reports a broken lid. You get a large white tub at the lowest shelf price of the white rows, provided you can accept that UK buyers do not agree how thick it is. It is the best value in this folder.
Pros
Cons
Best for: A 500 ml white tub when you can accept that UK buyers disagree on thickness.
Less suitable: A sandy surface, a metallic gold, or a buyer who needs a stated waterproof rating.
Specifications
Common questions
How much paste is in the Mont Marte tub?
The listing says 500 ml, model MMAR23790, at £13.05 in this extract.
Do the UK reviews agree it is thick?
No. Some UK texts say it holds peaks on canvas. Others say it is too thin for a dense shape.
Does the listing state a dry time?
There is no dry-time field. One UK review says the directions claim about 30 minutes and a thin coat was still wet after 8 hours.
The Nicpro jar is 571 ml of white acrylic modelling paste, model MG-1114, at £16.99, listed as medium viscosity and not water resistant. The bullets name canvas and wood, and the spec also lists cloth, cardboard, glass, and ceramics. The star line is 4.6 from 359 reviews. Five of the first 50 texts are from the UK: they include stencil use and a good price, and one UK text describes an overpowering smell, a runny body, and a sticky film that was hard to smooth. Most written texts in the extract are from the United States, so the 359 count is not a British sample. There is no hour field for drying, only a quick-drying bullet. You are buying a stated 571 ml white tub after you have read that smell complaint and the not-water-resistant line.
Pros
Cons
Best for: A 571 ml white tub if you have read the UK smell complaint and the not-water-resistant line.
Less suitable: A waterproof paste, or a buyer who wants the written reviews to be mostly British.
Specifications
Common questions
Is the Nicpro paste listed as waterproof?
No. The water-resistance field says not water resistant.
What do UK reviews say?
Five of the first 50 texts are from the UK. They include stencil use and a good price. One UK text describes an overpowering smell, a runny body, and a sticky film that was hard to smooth.
How big is the jar?
571 ml, item weight 500 g, model MG-1114, £16.99 in this extract.
The second Kamenskaya listing is model 4745091131610, 500 ml and 721 g, at £21.99, and the surface field names canvas, paper, wood, and walls. The usage field says indoor. The extract prints both 'Is Waterproof: True' and 'Water Resistance Level: Not Water Resistant', and both stay. The cure field says 24 hours, and a bullet compares the body with a lighter self-hardening clay that firms as it dries. The star line is 4.5 from 219 reviews. Short UK texts call it easy to use; they do not describe mixing. One French text says it lost volume as it dried. Walls on the surface field are not a specification for a rented wall or a wet room. You would read the conflicting water lines before you relied on them.
Pros
Cons
Best for: A sculpting paste when you will read the conflicting water lines before you rely on them.
Less suitable: An outdoor waterproof coating, or a buyer who wants one Kamenskaya row instead of two.
Specifications
Common questions
Can this listing be used on walls?
Walls are in the surface field. The usage field says indoor. That is not a specification for a rented wall or a wet room.
Is it waterproof?
The extract prints both 'Is Waterproof: True' and 'Water Resistance Level: Not Water Resistant'. Both stay.
How is this different from Kamenskaya dense white?
This model is 4745091131610 and 721 g. Dense white is 4745091131498 and 499 g. Both say 500 ml and £21.99 in these extracts.
The Kamenskaya dense white is 500 ml and 499 g, model 4745091131498, at £21.99, sold as a very dense white plastic mass for indoor canvas. The bullet says water resistant, while the usage field says indoor, so those two lines do not describe an outdoor coating. The cure field says 24 hours. The star line is 4.4 from 91 reviews. In this extract, one UK text says only 'HAPPY', and crack-resistance comments are mostly from the United States. US texts describe a smooth dense paste that sands and does not crack; those are not UK reviews. This is not the 721 g Kamenskaya jar, which shares the £21.99 shelf price and the 500 ml line. You would be choosing a dense white tub on a written slice that is mostly not British.
Pros
Cons
Best for: A dense white 500 ml tub if you accept that the written slice is mostly not British.
Less suitable: Someone who needs UK review text, or who thinks this is the 721 g Kamenskaya jar.
Specifications
Common questions
Is this the same jar as the other Kamenskaya listing?
No. This ASIN is model 4745091131498 at 499 g, sold as dense white. The other kept Kamenskaya ASIN is model 4745091131610 at 721 g.
What do the written reviews cover?
The star line is 4.4 from 91 reviews. In this extract, one UK text says only 'HAPPY'. Crack-resistance comments are mostly from the United States.
Does the listing say waterproof and outdoor?
The bullet says water resistant. The usage field says indoor.
The RICH listing is a white fine structural paste in a pail, title and weight 3.5 kg, at £41.95. The unit count says 3,500 ml and another line says 400 ml, so the extract does not tell you which volume is wrong. The material field says Clay, the viscosity field says medium, and the specific-uses field says inside, while bullets also say waterproof and weatherproof. The star line is 4.2 from 59 reviews. The texts in the extract are from Germany and Italy: several German texts say it can sit thickly on canvas, and several say it cracks as it dries and smells strongly. None of those texts is labelled United Kingdom. You would check the live size before treating £41.95 as a bulk buy, and you would not turn the German crack notes into a British trial.
Pros
Cons
Best for: A bulk white paste only after you have checked the live size and accepted non-UK review texts.
Less suitable: A small gold effect, a coarse-sand tin, or a price-per-litre claim.
Specifications
Common questions
How much paste is in the RICH bucket?
The title and the weight say 3.5 kg. The unit count says 3,500 ml. Another line says 400 ml. The extract does not say which line is wrong.
Are the crack and smell comments from the UK?
No. The texts in the extract are from Germany and Italy. Several German texts say it cracks as it dries and smells strongly. The star line is 4.2 from 59 reviews.
Does the listing say it is for indoor use?
The specific-uses field says inside. Bullets also say waterproof and weatherproof.
Each score is out of 100 on the nine amazon.co.uk listings kept in this comparison, snapshot 16 October 2026. Thirty-five points come from the star line, with a deduction when the file has fewer than 50 reviews. Twenty-five points come from what you can check on the listing: a body you can name, a volume that agrees with the title, and a water line that does not print both answers. Twenty points compare the shelf price with that check, inside this folder only. Twenty points come from the written reviews actually in the file, and UK texts count more than a German or US slice. This is not a laboratory test and it does not rank the wider UK aisle. Liquitex Basics, Winsor & Newton professional modelling paste, and Daler-Rowney texture paste are outside this set.
Amazon star line
35%The base is the stars divided by 5, times 35, rounded. Subtract 12 when the file has fewer than 10 reviews, or 4 when it has 10 to 49. A count of 50 or more takes no sample deduction. Marabu at 4.8 from 6 and Vigorder at 5.0 from 1 lose the under-10 deduction, so a high star line is not the top pick.
Listing you can check
25%A clear body and an agreed volume take the high end: smooth white, flexible white, coarse sand, or metallic gold. A clash of grams and millilitres, or waterproof beside not water resistant, takes the low end. RICH prints 3.5 kg, 3,500 ml, and 400 ml. Vigorder prints 850 g, 800 g, and 600 ml. Kamenskaya 721 g prints both water answers.
Price against that check
20%Price is judged inside this folder only, against the listing you can actually check. A 100 ml gold tin, a file under 10 reviews, or a bucket whose millilitres disagree cannot take the top of this block. Do not divide the RICH price by a litre. The best value is the lowest white-tub price among white rows with a large review file.
Written reviews in the file
20%UK texts count more than a star line whose written slice is German or American. A thickness split, an opened jar, or a smell note stays in the score as a limit. Mont Marte has the largest file, 1,159 reviews, and UK texts both hold peaks and call it too thin. Kreul, Marabu, and RICH have no UK-labelled text in the extract.
Name the body before the brand. Smooth white, flexible white, coarse sand, and metallic gold only share the search words. A clear gel, a wall filler, and a wood-repair epoxy are different products. The nine shelf prices below are the amazon.co.uk extracts, and they move.
Structural paste on amazon.co.uk is the thick acrylic medium UK shops also call modelling paste or texture paste. You knife it on so a painting stands up in relief. The nine listings in this comparison are artist pastes. They are not wall filler, not a wood-repair epoxy, and not a clear gel. A title that says texture can still be any of four bodies: smooth opaque white, flexible white, coarse sand, or a small metallic gold.
Marabu is metallic gold in a 100 ml tin at about £10.30. It is a stencil paste, not a 500 ml white modelling tub. The low shelf price is the gold effect. It is not a cheaper version of Mont Marte or Liquitex.
White paste lightens acrylic if you mix it in. Paint over the dry film if the colour must stay true. A clear gel is the other product. These nine listings are opaque pastes, not that gel.
Will not crack is a bullet, not a test. Liquitex states 24 hours and UK texts on thick work mention 48 hours and about 72 hours. Paint a skin-dry film and the layer underneath is still wet. Wash tools before the paste dries. Do not spray it.
Body comes first. Smooth opaque white, flexible white, coarse sand, and metallic gold are different pastes, even when the title only says texture. In this set the smooth white rows are Mont Marte 500 ml, Nicpro 571 ml, and Vigorder, whose grams and millilitres do not agree. Flexible white is Liquitex 8916, 473 ml, which the listing says dries more slowly to a hard yet flexible film. It is not the hard Liquitex paste sold for rigid supports. Dense white Kamenskaya is 499 g.
Match the volume to the job, and only where the listing agrees with itself. 100 ml, the Marabu gold tin, is a stencil. About 500 ml is a canvas tub: Mont Marte 500 ml, Nicpro 571 ml, and both Kamenskaya jars. Liquitex is 473 ml. Kreul is 250 ml and the item weight is 125 g. RICH is titled 3.5 kg, the unit count says 3,500 ml, and another line says 400 ml, so do not turn £41.95 into a price per litre. Vigorder prints 850 g, 800 g, and 600 ml. Those three lines stay unresolved.
Three typical situations, each with a recommendation from this comparison.
You want a named flexible film and you can wait out a thick layer. Liquitex model 8916 is 473 ml at about £21.20, with 4.7 from 881 reviews. The listing says hard yet flexible. UK texts on thick work mention 48 hours and about 72 hours. It is the top pick in this folder, and it is not the hard Liquitex paste for rigid supports.
You want about 500 ml of white paste and you can accept that UK buyers disagree on thickness. Mont Marte is about £13.05, with 4.6 from 1,159 reviews, the largest file here. Some UK texts hold peaks. Others call it too thin. That split is why it is the best value and not the top pick.
Sand, gold, or a bulk bucket only share the search words with the white tubs. Kreul Solo Goya is 250 ml of coarse sand at about £16.86, with a 6 hour field and 4.7 from 92 reviews. The written texts in the extract are not labelled United Kingdom. One German text says grains can fall off when you paint over them.
The top pick in this folder is Liquitex flexible modelling paste, model 8916, 473 ml, at about £21.20, with 4.7 from 881 reviews. The listing says a hard yet flexible film and a 24 hour cure field, and UK texts on thick work still mention 48 hours and about 72 hours. The best value is Mont Marte 500 ml at about £13.05, with 4.6 from 1,159 reviews, the lowest price among the white tubs with a large review file, and UK texts disagree on thickness. Marabu at 4.8 from 6 and Vigorder at 5.0 from 1 are not the top pick. These nine listings are not a ranking of every modelling paste in the UK.
Mont Marte Modelling Paste 500 ml
About £13.05 for 500 ml, 4.6 from 1,159 reviews, the lowest white-tub price, with UK texts split on thickness.
