Modelling paste vs gel medium

Updated: October 2026

You are about to buy a clear gel because the title said texture, or a white paste so the colour stays bright. Modelling paste vs gel medium is that mix-up. Paste in this comparison dries opaque and lightens a colour you mix into it. Gel dries clear, or leaves only the texture particles in it. None of the nine amazon.co.uk rows is a clear gel. Prices stay on our [Structural paste](/hub/painting-supplies/structural-paste) comparison. The order of bodies is on the [modelling paste buying guide](/hub/painting-supplies/structural-paste/sub/structural-paste-buying-guide). Peter F. read those listings on 16 October 2026 and did not dry a gel beside a paste. A qualifying purchase can earn a commission at no extra cost to you.

What each one dries like

Jackson's Art Blog, on 13 July 2026, puts the difference in one place: gels dry clear or leave only their texture particles, while pastes stay closer to how they looked wet and are stiffer and more opaque. It is a UK explanation of the mediums, not a test of these nine jars. Cass Art says gels are transparent and pastes are almost completely opaque. Golden tubs are not in this amazon set. Choose paste when the film should stay opaque, and you will paint it afterwards or accept a lighter tint. Choose gel when the colour must stay clear. A heavy gel can hold a mark. It does not become a white modelling paste because the mark is tall.

Colour, peaks, and grit

White modelling paste lightens acrylic if you stir the colour in. Paint over the paste when it is dry through if the hue must stay true. A gel that dries clear does not add that white. It can still change gloss. It will not turn the painting chalky the way a white paste does. Coarse sand paste is not a gel with grit. Kreul Solo Goya dries white, matt, and opaque, so the ground goes pale and sandy. Marabu is already metallic gold, not a clear gel that leaves an underpainting untouched. A paste that UK buyers call too thin will not hold a ridge even though it is opaque. Less white still lightens.

When a flexible support wants both

Hobbycraft's note on Daler-Rowney texture paste says that on a flexible surface you mix that paste with impasto gel and increase the gel as the layer gets thicker. That is not a 50/50 recipe for Mont Marte, Nicpro, Vigorder, or Kamenskaya. Jackson's also mentions a 50/50 mix on the hard Liquitex modelling paste, a different SKU from the flexible jar in this set. Use that mix note only when the support moves and the note names the paste you bought. Liquitex Basics is limited to non-flexible supports. The flexible Liquitex paste here is a different product, and its how-to still talks about thin layers dried slowly. Layer steps are on the how to use modelling paste page.

None of these nine is a clear gel

Every row in this comparison is a paste. Liquitex model 8916 is flexible modelling paste. The spec item form says Gel. That word is a form field, not a clear gel medium. The listing still describes a hard yet flexible film. Do not buy it when you wanted a transparent gel. Both Kamenskaya jars are texture pastes, neither of them clear. Kreul dries opaque. Marabu is metallic gold. RICH is a white fine structural paste whose volume lines disagree. If the colour must stay true, this set does not contain your gel. Buy a clear gel, from a listing that says it dries clear, if the colour has to stay unchanged.

Common questions

Which one dries clear?
Gel medium dries clear, or leaves only its texture particles, as Jackson's Art Blog described on 13 July 2026. Modelling paste stays closer to how it looked wet and is more opaque. White paste in this set dries white or off-white. Marabu dries metallic gold. Kreul dries as a white sandy film. None of those is a clear gel.
Will modelling paste change my acrylic colour?
Yes, if you mix a white paste into the colour. The hue lightens. Paint over the dry film when the colour must stay true. A clear gel does not add that white. It can still change the sheen. Marabu is already gold, so mixing it is not the same as tinting a white ground.
Can a heavy gel hold peaks like paste?
A thick gel can hold a mark. It still dries clear or shows only its particles, which is a different result from an opaque paste peak. Cass Art treats Golden pastes as almost completely opaque and gels as transparent. If you need a white ridge you will paint later, the paste is the body. If you need the colour to remain itself, the gel is the body.
Is Liquitex 8916 a gel because the form field says Gel?
No. Model 8916 is professional flexible modelling paste, 473 ml. The item form field says Gel, and the listing still describes an opaque-style modelling paste with a hard yet flexible film. It is not a clear gel medium. The hard Liquitex paste for rigid supports is a different product again.
When would I mix paste with gel?
When the maker of that paste says so for a flexible support. Hobbycraft's line is about Daler-Rowney texture paste: add impasto gel and increase the gel as the layer gets thicker. That is not a universal 50/50 for the nine amazon rows. A 50/50 note on Jackson's hard Liquitex paste is a different SKU from 8916.
Is coarse sand paste a gel with grit?
No. Kreul Solo Goya is a coarse-sand structural paste that dries white, matt, and opaque. The grit sits in a paste, so the surface goes sandy and pale. A clear gel with sand would leave the colour under it more visible. This comparison does not contain that gel.
