The best Soudal silicones, compared.
Top pick: Trade multi-purpose white 2-pack Best value: Trade multi-purpose white 3-pack – Best price against a pack count the specification agrees with, for ceramic, glass and wood: about £12.30, 4.4 from 33 ratings, title and specification both say three. Updated 22 October 2026.
Silicone sealant in a UK cartridge is a moisture-curing paste for a joint that moves or stays wet: a bath edge, a tiled splashback, a window perimeter or a roofline. Paint does not stick to the cured bead, so the colour you gun is the colour that stays. Neutral low-modulus silicone is the usual choice for uPVC, many plastics and frame perimeters. An acetoxy cartridge smells of vinegar while it cures and is a poor match for PVC. A fungicide line on a general tube is a weaker claim than a sanitary silicone for a shower that stays humid. A moving frame wants a high-movement low-modulus class. Buy clear or white to match the joint, because you cannot paint the bead later. Count the tubes in the box against the title before you compare a pack. A photo that shows more tubes than the specification is not a saving. Keep standard silicone off marble and granite, and off the edge seal of a sealed glazing unit.

Personal buying guide
Question 1 of 2
Where is the joint?
The white trade 2-pack is about £9.80 with 5.0 from four ratings, and two very short reviews say it works and that the price beat a local supplier. Neither review describes a joint, a smell or a cure time. The title says 2 pack while the package-quantity field says 1, and the specification leaves the item count blank. The listed weight is 760 g. Bullets name a fungicide and ceramic, glass and wood, and no applicator is listed. A perfect star line on four ratings is not the same evidence as 118 ratings on the white Silirub LMN. It is a small white multipack only if two tubes are in the box and the joint is ceramic, glass or wood rather than uPVC.
Pros
Cons
Best for: A small white spare for ceramic, glass or wood after you confirm two cartridges arrived
Less suitable: Ranking by stars alone, uPVC frames, and a first tube when you want a large review sample
Specifications
Common questions
How many cartridges does the listing state?
The title says 2 pack. The specification does not state the number of items or the unit count. The package-quantity field says 1. The manufacturer part is 121643_X2. The listed weight is 760 g.
Does the listing say whether it is paintable or for outdoors?
The listing shows questions on outdoor use, whether an applicator is included and whether it is paintable, and it does not record an answer. No applicator is listed.
What water resistance and materials are named?
Water resistance is stated as waterproof, under other special features. Materials named are ceramic, glass and wood. A bullet says it contains fungicide to resist mould growth. The cure is not named.
Clear Silirub LMN is a single 300 ml cartridge at about £8.54, rated 4.7 from 67 reviews. The title says neutral silicone, and the surface list includes pipe, gutter, tile, sink, tub, window and door. Reviewers used it on polycarbonate roof caps and called the result waterproof, and one used it on an aluminium splashback. The specification states a full cure of 24 hours, while one review says it dried quite quickly and wiped clean once cured. It still smells a bit while drying, and that reviewer opened a window. Another buyer could not yet say whether it had stopped corrosion. The materials field only says silicone, so this row does not print the PVC line that the white LMN listing does. It suits a clear bead on glass, metal or a roof cap when white would show, at a similar price, with a smaller review sample than the white tube.
Pros
Cons
Best for: Clear joints on glass, aluminium, gutters and roof caps where a white bead would show
Less suitable: A job that needs PVC printed in the materials line, natural stone, and a white colour match
Specifications
Common questions
How many cartridges does the listing state?
The title is a single 300 ml cartridge. The specification says number of items 1 and unit count 300 millilitres. The manufacturer part is 114573.
Does the listing name the cure?
Yes. The title says neutral silicone. The materials field only says silicone. A fungicide is not named.
What water resistance is stated?
Water resistance is stated as water resistant. The specification states a full cure of 24 hours. Surfaces named include pipe, gutter, tile, sink, tub, window and door.
The white trade 6-pack is about £21.28, the highest price in this set, with six items in the specification and 4.6 from 32 ratings. This listing alone states a maximum gap of 30 mm, a tensile strength of 750 pounds per square inch, initial hardening in 7 minutes and a full cure of 24 hours. A reviewer used it on a shower and a bath. Others call it reliable and easier than a cheaper paste, though one report says a strong smell lingered after the job. The listing does not name the cure, and the matching Soudal Trade Multi-Purpose sheet is acetoxy with a skin nearer 20 minutes, so the 7-minute line stays a listing figure rather than a sheet figure. The seven reviews recorded do not repeat a leak or a short count. You pay for more cartridges, not a higher movement class.
Pros
Cons
Best for: A store of white cartridges for glass, metal, wood and ceramic tile when the box contains six tubes
Less suitable: A single bath reseal, uPVC frames, and a per-tube price worked out before the tubes are counted
Specifications
Common questions
How many cartridges does the listing state?
The title says 6 pack. The specification says number of items 6. The manufacturer part is 121643_X6. Unit count is not stated.
Does the listing say whether it is for windows?
The listing shows questions on windows, other colours and whether it is waterproof, and it does not record an answer. The water-resistance field says waterproof. The cure is not named.
What gap and materials are named?
This listing states a maximum gap of 30 mm and a tensile strength of 750 pounds per square inch. Bullets name glass, metals, wood and ceramic tile. A bullet says it contains fungicide.
The clear trade multi-purpose title says 6 pack and the price is about £12.95, with 4.6 from 32 ratings, but the specification says number of items 1 and the unit count is 1. The listed weight is 310 g, which sits with a single cartridge rather than a six-tube box. Bullets still cite a fungicide and ceramic, glass and wood, and the eight reviews recorded praise easy application without describing a failed joint. The only negative note is that one buyer found cheaper alternatives. The listing does not name the cure, and outdoor, colour and paintable questions are shown without an answer. Until you count the tubes, dividing about £12.95 by six is not a saving. Treat the row as an unclear clear cartridge, not as a confirmed six-pack.
Pros
Cons
Best for: A clear bead on ceramic, glass or wood after you have confirmed how many tubes are in the box
Less suitable: A per-tube price based on six cartridges, and uPVC frames

The white Silirub LMN 300 ml cartridge is listed at about £8.20 on amazon.co.uk and carries 4.5 from 118 ratings, the largest sample in this set. The title names neutral silicone, and the materials line names wood, metal, PVC and glass, which is the perimeter job a low-modulus tube is bought for. One reviewer sealed a leaking bath-to-tile joint and reported a skin after about 30 minutes and a set within 24 hours. Another warmed the tube and sealed external van trim without reporting a leak. The bullets promise a non-vinegary scent, yet a reviewer still found the smell strong, so a low-odour claim is not a no-odour result. Cleanup is messy because the paste is not water-based, and one review says a bead discoloured and could be rubbed off. It is the top pick when you want one named-neutral 300 ml tube with a large UK sample, though the listing does not name a fungicide and this is not a sanitary silicone.
Pros
Cons
Best for: White movement joints on uPVC, wood, metal or glass, and a bath-to-tile edge when a sanitary silicone is not required
Less suitable: Marble or granite, the edge of a sealed glazing unit, and a humid shower that needs a named sanitary fungicide
Specifications
Common questions
How many cartridges does the listing state?
The title is a single 300 ml cartridge. The specification says number of items 1 and unit count 300 millilitres. The manufacturer part is 123207.
Does the listing name the cure?
Yes. The title says neutral silicone. The materials line names wood, metal, PVC and glass. A fungicide is not named on the listing.
What water resistance is stated?
Water resistance is stated as water resistant. One reviewer sealed a bath-to-tile joint and reported a skin after about 30 minutes and a set within 24 hours. That is a listing review, not a sanitary rating.
The brilliant white trade multi-purpose 3-pack is about £12.30, and both the title and the specification say three items, with 4.4 from 33 ratings. Bullets name a weathertight flexible seal, a fungicide, and ceramic, glass and wood. Reviewers describe a creamy paste that works with masking tape and a rubber shaping blade, and they call the colour a very bright white. On a hot day it goes off quickly and can drag if you pause. One reviewer could not yet say how long it lasts or whether the fungicide holds. The listing does not name the cure. Soudal's Trade Multi-Purpose sheet for this family describes an acetoxy sealant and does not treat PVC as a reliable substrate, so this pack is the best value here for ceramic, glass and wood when you want three tubes, not for a uPVC frame.
Pros
Cons
Best for: Ceramic, glass and wood joints where a bright white general silicone with a fungicide bullet is enough and you want three cartridges
Less suitable: uPVC frames, natural stone, and a job that needs the word neutral printed on the listing

The title says 3 pack. The specification says number of items 3 and unit count 3. The manufacturer part is 121643_X3. Title and specification agree.
Does the listing say whether it is paintable or for windows?
The listing shows questions on windows, other colours and whether it is waterproof, and it does not record an answer. No yes or no is stated in the bullets or the specification. The water-resistance field says waterproof.
What materials and fungicide are named?
Materials named are ceramic, glass and wood. A bullet says it contains fungicide to resist mould growth. The cure is not named on the listing.
This brilliant white Silirub LMN listing is the only one in the set whose bullets name a low-modulus neutral cure and ISO 11600 F&G 25 LM. The specification says three tubes and 900 ml, at about £17.03, with 4.4 from 26 ratings. Materials named include PVC-u, plastics, masonry, metal, wood and most glass types. Reviewers who received the paste say it does what the wording on the tube says and that it cleans up across a range of jobs. One reviewer says the photo showed four tubes and only one arrived, at about £15 for that single tube, which removes the multipack saving. The title does not state a pack count in a clean form. Read it when you want the movement class printed on the listing, and skip the photo until the parcel matches the three-tube specification.
Pros
Cons
Best for: uPVC and glazing perimeters when the parcel matches the three-tube specification
Less suitable: Buyers who trust the main photo for a tube count, natural stone, and a secondary seal on insulating glass

Does the listing name the cure?
Yes. The title says low modulus neutral cure, and a bullet says neutral cure. A bullet also names ISO 11600 F&G 25 LM. A fungicide is not named.
What materials are named?
The listing names PVC-u, plastics, masonry, metal, wood and most glass types. Water resistance is stated as water resistant. One review says the photo showed four tubes and only one arrived.
The clear trade 3-pack is about £12.31, with the title and the specification both saying three, and it has 4.1 from only eight ratings. Two reviewers say the photo shows four tubes and the parcel contained three, and that the short count removes the saving. One review used it on a conservatory roof in full sun and said it was still doing the job at the time of writing. Bullets include a fungicide and ceramic, glass and wood. The listing does not name the cure. Eight ratings are a thin sample beside the 118 on the white Silirub LMN. Price it as three clear tubes for ceramic, glass or wood, not as the four-tube picture, and not as a neutral-cure frame sealant.
Pros
Cons
Best for: A clear joint on ceramic, glass or wood when you have counted three tubes in the parcel
Less suitable: uPVC frames, shopping from the main photo, and treating eight ratings as a large sample

Eight amazon.co.uk listings were scored on a 0–100 scale. The method file checks four things and then lists deductions. It does not print point values. Amazon stars and review count are 40 points. A thin sample under 10 ratings, and especially under 5, is scored down even when the stars are 5.0. Whether the listing names the cure, and whether it names ISO 11600 F&G 25 LM, is 25 points. Whether the title, the specification and the reviews agree on the tube count is 15 points. Price in GBP against the count that agreement supports is 10 points. A six-pack title with a specification of one item is not priced per tube. Listing faults are 10 points, so the five weights sum to 100. Those faults are a cure the listing does not name, a photo or title count the reviews dispute, a package-quantity field that contradicts the title, and a smell, drag or discolouration the reviews record. The method file does not set a numeric cap on that block. The 10 points only reduce a score. They are not an award. The highest score is the top pick. The best price against a pack count the specification agrees with, for ceramic, glass and wood, is the best value. One of each. This order is the listing order. It is not a laboratory test.
Amazon stars and review count

The method file lists these faults beside the four checks and does not print a point cap. The weight of 10 brings the sum to 100. These points only reduce a score. They are not an award.
Match the cure to the substrate, then the colour, then the tube count. A fungicide bullet is not a sanitary silicone, and a marketplace photo is not the pack count.
Soudal silicone on amazon.co.uk, in this set, is a cartridge sealant in two families. Silirub LMN is a low-modulus neutral-cure building and glazing silicone. The other rows are multipacks titled Trade Multi-Purpose construction sealant silicone. UK buyers use them on a bath, a tiled joint, a window perimeter or a roofline. The quality check is whether the cure matches the substrate.
A title that says construction does not make a trade multipack neutral. The Trade Multi-Purpose sheet is acetoxy and lists PVC among substrates with no good adhesion. Read the cartridge.
Paint does not stick to silicone. Standard silicone stains marble and granite. Tool the bead before the skin forms. Silirub LMN's sheet puts the skin at about 7 minutes.
Reviews on more than one listing say the photo shows four tubes and fewer arrive. A six-pack title with a specification of one item is not six tubes. Count the box.
Neutral low-modulus silicone, such as Silirub LMN, is the listing to read for uPVC, many plastics and frame perimeters. The trade multipacks do not name the cure. The matching Soudal sheet is acetoxy, smells of vinegar while it cures, and does not treat PVC or concrete as reliable substrates. Ventilate while that family cures. ISO 11600 F&G 25 LM appears in the bullets of one brilliant white listing only. The other neutral titles name neutral silicone and do not print that class on the listing.
These listings are clear or white, including brilliant white. Colour is final because paint does not adhere. A fungicide bullet on a general tube is a weaker claim than Stay Fresh or Trade Sanitary for a shower that stays humid, and those sanitary products are not in this comparison. Soudal sizes joints at 5–30 mm, width about twice depth. One white 6-pack listing states a 30 mm gap. The others do not. Price a pack only after the title, the specification and the parcel agree.
Three typical situations, each with a recommendation from this comparison.
You are sealing uPVC, wood, metal or glass and you need the word neutral on the listing. Silirub LMN white 300 ml is the top pick at about £8.20, 4.5 from 118 ratings, with wood, metal, PVC and glass named. It is not a sanitary silicone, and one review found the smell stronger than the low-smell bullet.
You want three white cartridges for ceramic, glass or wood, with a fungicide bullet, and the title and the specification both say three. The trade multi-purpose white 3-pack is the best value at about £12.30, 4.4 from 33 ratings. The listing does not name the cure. The matching Soudal sheet is acetoxy and is a poor match for PVC.
White would show, and you want one clear 300 ml tube with neutral in the title. Clear Silirub LMN is about £8.54, 4.7 from 67 ratings. Reviewers used it on polycarbonate roof caps and an aluminium splashback. The materials line says silicone and does not name PVC.
The top pick is Silirub LMN white 300 ml at about £8.20. It is a single cartridge, 4.5 from 118 amazon.co.uk ratings, the largest sample here, and the title names neutral silicone. The materials line names wood, metal, PVC and glass. A bath-to-tile review cites a skin after about 30 minutes and a set within 24 hours. The smell can be stronger than the low-smell bullet, cleanup is messy, and no fungicide is named. The best value is the trade multi-purpose white 3-pack at about £12.30, 4.4 from 33 ratings. The title and the specification both say three, and a bullet names a fungicide for ceramic, glass and wood. That listing does not name the cure. Soudal's Trade Multi-Purpose sheet for this family is acetoxy and does not treat PVC as a reliable substrate, so it is not the uPVC tube. This order follows the listing scores. It is not a laboratory test.
