The best Pattex silicones, compared.
Top pick: Pattex AC411 acrylic for wood and parquet Best value: Pattex bathrooms and kitchens sealant, transparent, 50 ml – Best value for one short transparent joint without a gun: about £9.55, 4.4 from 141 ratings. Not the best price per millilitre. Updated 22 October 2026.
Silicone in a UK bathroom or kitchen is a flexible seal for a joint that stays wet. Decorator's acrylic fills a still gap you will usually paint. Packs under one logo are not one chemistry. A sanitary cartridge lays a new bead on a bath, basin or shower edge. A coating belongs only on a bead that is still stuck. A frame sealant is for a window perimeter. Acrylic for wood can still say silicone on the title, and that word does not make it a wet-room paste. Which family fits the joint is set out in the [silicone buying guide](/hub/fillers-adhesives-and-sprays/pattex-silicone/sub/pattex-silicone-buying-guide). Acetoxy cure smells of vinegar and suits glass and glaze. Neutral sheets name mirrors, some plastics and a higher movement class. Do not copy that class onto an acetoxy cartridge. A short tube is one tap if you have no gun. A full run needs a cartridge. Check the colour you pay for, because a colour field and a RAL code can disagree. Only the EN 15651 part named on the sheet applies.

Personal buying guide
Question 1 of 2
What are you doing?
Pattex AC411 is listed at about £9.48 with 5.0 from four amazon.co.uk ratings, and the only written review says ok. The title says acrylic silicone for wood and parquet, the material field says silicone, and the model line says ml 300 - Pino while the unit count is 1. The surface line is wood and the listing says waterproof. The November 2018 sheet is an acrylic dispersion for wood, paintable after about 4 to 6 hours, with movement up to 10 percent, and not for driving rain, high humidity or glass. Four ratings at 5.0 do not make this a bathroom silicone, and the title's silicone word does not override that sheet. The item weight is 1.54 kg, which does not by itself confirm a 300 ml cartridge. Laminate and an applicator are asked on the listing and not answered. Use it on a wood or parquet gap you will paint, and leave it off the bath.
Pros
Cons
Best for: You have a wood or parquet gap you will overpaint, and you have read the title as acrylic.
Less suitable: A bath, a shower, a window frame, or a purchase made because the title contains the word silicone.
Specifications
Common questions
Is it waterproof?
The listing sets water resistance to waterproof. The November 2018 sheet is an acrylic for wood, not for driving rain, high humidity or glass. Leave it off the bath.
Which surface does the listing name?
Wood. A question about laminate flooring is asked and not answered. The sheet is paintable after about 4 to 6 hours, with movement up to 10 percent.
Does it include an applicator?
The listing asks that and does not answer it. An applicator is not stated. The model line says 300 ml and the unit count says 1.
Across 1,157 amazon.co.uk ratings, the Pattex 1506138 cartridge is the 300 ml white anti-mould pack used on a sink edge, a bath or a shower cubicle. At about £14.07 in the 19 October 2026 file it is the top pick in this set when you are laying a new sanitary bead and you already have a gun. Reviewers describe a soft white paste that tools while it is fresh, and one cartridge was enough for a shower reseal. The written notes are from Italy and Spain, not the United Kingdom, so the stars are the global amazon.co.uk line rather than a UK panel. The listing does not state a water-resistance level. Shoppers who read the description as transparent received white, some nozzles were missing or already cut, and a 3x reading produced a single cartridge. The bead can yellow in the shower, some people replaced it after about a year or two, and one reviewer put the slower neutral cure at about two days.
Pros
Cons
Best for: You are laying a new white sanitary bead on a sink, bath or shower cubicle, and you will check the nozzle and the colour before you pay.
Less suitable: A plastic bath, natural stone, a loose bead you hoped to coat, a window frame, or a wood gap you will paint.
Specifications
Common questions
Can it be used in a bathroom?
The bullets name sinks, baths and shower cubicles, including wet rooms that get mould. That is a listing use, not a plastic-bath certificate. A plastic bath, natural stone and permanent immersion stay off this cartridge.
Is it waterproof?
The listing asks that and does not give a water-resistance level. Water resistance is not stated. Do not treat a blank cell as a waterproof claim.
What colour is it?
The colour field is white. Reviewers say some description text read as transparent. Check the colour on the page you pay for.
The Pattex bathrooms and kitchens tube, model 2721071, is 50 ml of transparent silicone at about £9.55, with 4.4 from 141 amazon.co.uk ratings. Reviewers use it for a short run around a stainless-steel sink, a shower leak, or a touch-up when there is no cartridge gun in the house. The listing says neutral, waterproof and mildew resistant, and the surface line is shower. The written notes are from Italy and Germany, not the United Kingdom. The bullet's neutral wording has not been matched to the 25 percent alkoxy sheet, so this tube is not that movement class. It is hard to press into one continuous bead, it dries out if air is left inside, and several people call the fill small for the price. It is the best value in this set when the job is one short joint and you will not buy a gun. Per millilitre it costs more than the 300 ml white cartridge, and it will not reseal a whole bathroom.
Pros
Cons
Best for: You need one short transparent bead in a bathroom or kitchen and you do not own a gun.
Less suitable: A full bathroom of new joints, a coat over an old bead, a window frame, or a wood gap you will paint.
Specifications
Common questions
Does this need a cartridge gun?
No. The box line is one 50 ml tube. It is the pack for one short joint when you will not buy a gun. It is hard to press into one continuous bead.
Is it for showers?
The surface recommendation is shower. The title is bathrooms and kitchens. The fill is 50 ml, so it is a short repair, not a whole bathroom of new beads.
Is it waterproof?
The listing says waterproof. The neutral wording on the bullet has not been matched to the 25 percent alkoxy sheet.
Pattex SL 620 copper, article 1536090, is about £11.73 on amazon.co.uk with 4.3 from 18 ratings. The colour field is copper and the model line says RAL 8004, and the written reviews, from France, Spain and Italy rather than the United Kingdom, say that colour matches a frame they could not find in a hardware shop. The surface line is window, the compatible material is metal, and the listing says water resistant. The model line says 300 ml and the unit count says 1 ml, so the fill has to be read on the live page before you treat about £11.73 as a full cartridge. There is no repeated fault in the six written notes. It is a frame sealant in this set when the live fill agrees with 300 ml. It is not a sanitary bath bead, and the 2018 sheet does not make it EN 15651-3.
Pros
Cons
Best for: You are sealing a copper RAL 8004 window frame and you will check that the pack is 300 ml.
Less suitable: A bath or shower, a coat on an old bead, a wood gap you will paint, or a fill you have not confirmed.
Specifications
Common questions
What colour is it?
The colour field is copper. The model line says RAL 8004. The title article number is 1536090. Written reviews say that colour matches a frame.
Is it for windows?
The surface recommendation is window. The compatible material is metal. The June 2018 SL 620 sheet is EN 15651-1 and EN 15651-2, not a sanitary EN 15651-3 paste.
How much is in the pack?
The model line says 300 ml. The unit count says 1 ml. Read the live fill before you treat about £11.73 as a full cartridge.
Pattex Re-New, model 2589876, is a white 280 ml cartridge at about £14.28, with 4.2 from 370 amazon.co.uk ratings. The listing says it renews a kitchen, bathroom or shower seal without cutting out the old silicone, and that you use it with a gun. Some reviewers report little smell, a self-smoothing spout, and a coat on a shower tray that had not yellowed for them. The written notes are from Italy and Spain, not the United Kingdom. The Henkel sheet that lists showers also says Re-New is not for showers, wet rooms or permanent damp, so those two lines have to be read together. In the review file the coat stays soft after 24 to 36 hours, crumbles where it is thin, and lifts in water or at the first clean. Spouts arrive wide or missing, and cartridges have turned up past their expiry. This is a coat for a bead that is still stuck, not a new joint in an empty gap.
Pros
Cons
Best for: You have a white sanitary bead that is still attached and only stained, and you will keep the coat dry for the hours the sheet asks.
Less suitable: A loose or leaking bead, a shower you cannot keep dry, an empty gap, or a first-time bath reseal.
Specifications
Common questions
Do you cut out the old silicone first?
The bullets say it renews seals without removing the old silicone, masking paper or spatulas. That is for a bead that is still stuck. A loose or leaking bead has to be cut out.
Does it need a gun?
Yes. The contents line says use it with a silicone gun. The spout can arrive too wide or missing.
Is it waterproof?
The listing says water resistant. Reviews repeat a soft cure and lift in water. The sheet lists showers and then excludes showers, wet rooms and permanent damp.
Pattex SL 620, model 2111579, is listed at about £10.35 for a cartridge whose bullet says building-industry maroon RAL 8007 and 300 ml. The colour field on the same amazon.co.uk page says red, the item weight is 145 g, and the rating is 4.2 from eight reviews. The only written note calls it brown silicone with a glossy finish. That file is too thin to judge a frame colour from, and the three colour words do not agree. Water resistance and outdoor use are asked on the listing and not answered. The June 2018 SL 620 sheet is a neutral glazing and facade sealant to EN 15651-1 and EN 15651-2, movement 12.5 percent, about -30°C to +120°C. It does not declare EN 15651-3, so this is not a bath silicone and it is not a +150°C product. Buy it only if the live page, the RAL code and the photo describe the same maroon.
Pros
Cons
Best for: You need a maroon frame seal and you will confirm RAL 8007 on the page you pay for.
Less suitable: A bathroom bead, a coat over old silicone, a paintable skirting, or a colour match you cannot check.
Specifications
Common questions
What colour is it?
The colour field says red. A bullet says building-industry maroon RAL 8007. The one written review calls it brown with a glossy finish. Confirm the live page, the RAL code and the photo before you pay.
Can it be used outdoors?
The listing asks that and does not answer it. Outdoor use is not stated. The June 2018 sheet is a glazing and facade sealant, about -30°C to +120°C, and it is not a +150°C product.
Is it waterproof?
The listing asks that and does not give a water-resistance level. Water resistance is not stated. The item weight is 145 g against a 300 ml bullet.
Sista Neue Fuge is an 80 ml white squeeze bottle at about £16.87, with 3.9 from 639 amazon.co.uk ratings, the lowest star line in this set. The listing says you apply it to the old kitchen or bathroom joint, with a self-levelling nozzle and no cartridge gun. Reviewers have turned a short stained joint white again without cutting it out, and the bottle is easier to cap than a cartridge. The written notes are from Germany, not the United Kingdom. The paste is runny, the nozzle is wide for a narrow gap, and the built-in smoother is too small to coat a bead, so people fall back on tape or a separate tool. One review cites a length claim that did not cover 3 m of kitchen. The bead stays soft for days, yellows after months, and the nozzle clogs after the first joint. At this price for 80 ml it is a short coat on a sound joint, not a bargain refill. Tool it with water, not washing-up liquid, and keep it dry for at least six hours.
Pros
Cons
Best for: You want to coat a short, still-attached white joint, tool it with water, and keep it dry for at least six hours.
Less suitable: An empty gap, a loose bead, a long kitchen run, or a joint you expected the built-in tool to finish.
Specifications
Common questions
Does it go on an old joint?
The bullets say apply it directly to the old joint, with no tools and no scratching. It is a coat on a sound bead, not a new joint in an empty gap. Tool it with water and keep it dry for at least six hours.
Does it need a cartridge gun?
No. It is a squeeze bottle with a self-levelling nozzle. Reviewers say the nozzle is wide for a narrow gap and the built-in smoother is too small to coat a bead.
Is it waterproof?
The listing says waterproof. The bead stays soft for days in the review file, and it can lift at the first clean. The sheet cites about 5 m at 1 mm. One review did not get 3 m of kitchen from the bottle.
Seven amazon.co.uk listings were scored on a 0–100 scale. Amazon stars and review count are 45 points. A 4.4 from 1,157 ratings sits at the top of this set. A 4.4 from 141 ratings stays high. A 5.0 from four ratings does not. Whether the listing states the duty is 25 points: a sanitary surface, a mould line, a coating instruction, a window colour or a wood job counts, and a blank water-resistance line does not. Price against this set is 20 points. A short no-gun tube at about £9.55 scores on price. An 80 ml bottle at about £16.87 does not. Listing faults are 10 points, so the four weights sum to 100. The score sheet deducts up to 15 points for a colour field that disagrees with the bullet, a unit count that disagrees with the model line, a review count under 15, a title that says silicone for an acrylic sheet, and a repeated cure or lift complaint. Those faults sit inside the 10-point block. The highest score is the top pick, for a new white sanitary bead when you already have a gun. The 50 ml tube is the best value for one short transparent joint when you will not buy a gun. It is not the best price per millilitre. Prices are the amazon.co.uk shelf prices on 19 October 2026. Written reviews in the files are from Italy, Spain, Germany or France. This is not a laboratory test.

Separate the pack by the job before the logo. A new bath bead, a coat on a stuck bead, a window frame and a paintable wood gap are different pastes. A waterproof field is not a shower certificate, and a mould line does not fix damp.
A sanitary silicone is the paste for a new bath, basin or shower bead. A coating is only for a bead that is still stuck and sound. A loose or leaking bead has to be cut out. A window perimeter takes a frame sealant. A skirting you will paint takes an acrylic, even when the marketplace title still says silicone. Acetoxy cure smells of vinegar and suits glass and glaze. The acetoxy pressure-pack sheet excludes plastic baths, natural stone, paint, permanent immersion and food contact.
Re-New and Neue Fuge coat a bead that is still stuck. A loose or leaking bead has to be cut out. Neue Fuge is tooled with water, not washing-up liquid, and kept dry for at least six hours.
AC411's title says acrylic silicone. The sheet is acrylic for wood, not a shower paste. The 50 ml tube says neutral, and that word has not been matched to the 25 percent sheet. SL 620 is not a sanitary sealant and not a +150°C product.
Acetoxy paste is the wrong chemistry for natural stone. The pressure-pack sheet also excludes plastic baths, paint, permanent immersion and food contact. A fungicide does not fix a leak or black mould from damp.
A new bath or basin bead needs a sanitary silicone. A yellow but attached bead is the only job for Re-New or Sista Neue Fuge. A window perimeter is SL 620. A skirting you will paint is AC411. Acetoxy smells of vinegar and suits glass and glaze. Neutral sheets name mirrors, some plastics and a 25 percent movement class. Do not copy that class onto an acetoxy cartridge. The 50 ml listing says neutral, and that word has not been matched to a sheet code.
Re-New lists showers as a use and then excludes showers, wet rooms and permanent damp. Neue Fuge is an 80 ml coat, tooled with water and kept dry for at least six hours, with about 15 months of storage on its sheet. SL 620 storage is about 18 months. Match RAL 8007 or RAL 8004 to the frame. The colour field on the RAL 8007 listing says red, and the copper unit count says 1 ml against a 300 ml model line. The 50 ml tube is one tap if you have no gun.
Three typical situations, each with a recommendation from this comparison.
You are laying a new white bead on a sink, bath or shower cubicle and you already have a gun. Pattex 1506138 is the top pick: 300 ml at about £14.07, 4.4 from 1,157 ratings. The listing does not state water resistance. It is the wrong pack for a plastic bath, natural stone or a loose bead.
The bead is attached and only stained. Pattex Re-New is the coating cartridge at about £14.28, 4.2 from 370 ratings, and it needs a gun. The sheet lists showers and then excludes showers, wet rooms and permanent damp. A loose or leaking bead has to be cut out.
You need a copper frame seal and you will check the fill. Pattex SL 620 copper is about £11.73, 4.3 from 18 ratings, and the colour field agrees with RAL 8004. The unit count says 1 ml against a 300 ml model line. It is not a bath silicone.
The top pick is Pattex 1506138, the white 300 ml anti-mould cartridge at about £14.07, with 4.4 from 1,157 amazon.co.uk ratings. The listing names sinks, baths and shower cubicles. Water resistance is not stated, nozzles go missing, and reviewers report yellowing. The best value is Pattex 2721071, the transparent 50 ml tube at about £9.55, with 4.4 from 141 ratings, for one short joint when you will not buy a gun. It is not the best price per millilitre, and the neutral wording is not matched to the 25 percent sheet. AC411 is the lowest shelf price, at about £9.48, and does not receive the best value award.
Pattex bathrooms and kitchens sealant, transparent, 50 ml
Best value for one short transparent joint without a gun: about £9.55, 4.4 from 141 ratings. Not the best price per millilitre.
