The best silicone sprays, compared.
Top pick: Soudal silicone spray 5-pack Best value: Soudal SP400 – Best price among single 400 ml cans that still have several hundred reviews: about £6.46, 4.5 from 615 reviews. Updated 22 October 2026.
A silicone spray is an aerosol that leaves a thin silicone film. In a UK home it is bought to cut friction and shed water on hinges, uPVC window gear, rubber seals and rails. People look for it when a door is stiff or a lock squeaks, often after a fitter has named silicone rather than ordinary oil. Cartridge sealant, tube grease and skin adhesive are different products. A water-based craft release belongs in its own row. What to look for is a named lubricant, a temperature line on that can, a straw or a controllable nozzle, and reviews that talk about hinges and seals. Those checks are set out in the [silicone spray buying guide](/hub/fillers-adhesives-and-sprays/silicone-spray/sub/silicone-spray-buying-guide). The film is not a gap filler and it does not restore cracked rubber. Do not spray a part you will paint, and do not use it on brakes, pedals or steering wheels. Under GB CLP these aerosols are typically extremely flammable and pressurised. Ventilate, and do not store the can above 50 °C.

Question 1 of 2
Where will you use it?
The Soudal five-pack is about £20.33 with 4.8 from 46 reviews, and the saved listing does not state millilitres per can. A bullet says a long attachment nozzle is provided, and the ten review texts mention window hinges, squeaky doors, patio doors and, in one case, a winter jacket. No repeated defect is named in those texts, which is a thinner record than the 615 reviews on the single SP400. The colour field says black and the usage line says automotive, construction and home repair, without a temperature. A 4.8 on 46 reviews does not outrank a 4.5 from 615 when you cannot see the fill. Buy the pack only after the live page states the millilitres and you actually want five cans.
Pros
Cons
Best for: Someone who has checked the can size on the live page and wants several Soudal aerosols at once.
Less suitable: A first purchase where you need a stated 400 ml fill and a large review sample.
Specifications
Common questions
How much is in each can?
The saved listing says five pieces and does not state millilitres per can.
Does the listing mention a nozzle?
Yes. A bullet says a long attachment nozzle is provided.
What do the ten reviews cover?
Window hinges, squeaky doors, patio doors and, in one review, winter jackets. No repeated defect is named.
The clear Soudal three-pack is three 400 ml cans, 1,200 ml in total, at about £13.69, with 4.7 from five reviews and no review bodies in the saved listing. The water-resistance field says waterproof and the colour field says clear. Suitable materials are not stated, unlike the black three-pack at about £13.58, which lists fabric, glass, metal and more. Five ratings without a captured comment cannot show whether a straw arrives or whether the film suits a hinge. At roughly £4.56 a can it looks cheap beside the about £6.46 single, but you are paying for fill you cannot judge from reviews. Buy it when you already know this Soudal spray and you want three clear-labelled cans, not when this is your first can.
Pros
Cons
Best for: A repeat buyer who wants three clear-labelled 400 ml Soudal cans and already knows the film.
Less suitable: A first can, or any comparison that depends on reading how the spray behaved.
Specifications
Common questions
What colour is the listing?
Clear.
Is it waterproof on the listing?
Yes. The water-resistance field says waterproof.
Are there review texts?
No. The star line is 4.7 from 5 reviews, and the saved listing has no review bodies.
Liqui Moly 3310 is a 300 ml spray at about £10.95, rated 4.6 from 3,287 reviews. The listing’s upper temperature is 250 °C, the only temperature figure among these ten products, and the compatible-material line says plastics and rubber. Water resistance is not stated, and the best-sellers rank sits in Automotive rather than DIY & Tools. More than one review says there is no long nozzle for thin seals, so a narrow door gasket is harder to hit than with a straw. The listed weight is 179 g, against 320 g on the Soudal 400 ml can, and you are buying 300 ml rather than 400 ml. Many texts in that review file are not from the UK, so the count is not a UK-only sample. It fits car rubbers and plastic panels when that 250 °C line is the reason you opened the page. It is a weak default for a uPVC lock if you needed a straw and the lowest price.
Pros
Cons
Best for: Car rubbers and plastic panels when you want the only stated upper temperature in this comparison.
Less suitable: A narrow uPVC seal where you need a straw, or a buyer comparing 400 ml cans on price alone.
Specifications
Common questions
What temperature does the listing state?
The upper temperature rating is 250 °C. A lower figure is not in the saved listing.
Which materials are named?
The compatible-material line says plastics and rubber.
Do the reviews mention a straw?
Yes. More than one review says there is no long nozzle for thin seals.
The 3-IN-ONE 400 ml silicone lubricant is about £9.78 on amazon.co.uk, rated 4.6 from 2,383 reviews, which is the largest review count on a single can in this comparison. The compatible-material line names rubber, plastic, wood, vinyl and metal, and the review set includes sticking PVC doors, window runners, patio rails and locks. The manufacturer field says WD-40 Company and the part is 44015, with viscosity listed as low, so you are buying a light film rather than a grease that stays packed in a roller. Several reviewers say the straw was missing or would not stay in the nozzle, which matters on a lock keep where you do not want a cloud of spray on a white frame. There is no temperature figure on this listing. It is the top pick here for uPVC hinges and rubber seals because the sample is large and the materials are named, not because it is the cheapest can.
Pros
Cons
Best for: uPVC hinges, locks and rubber seals when you want the largest review sample on a 400 ml can.
Less suitable: A brake, a surface you will paint later, or a buyer who needs the lowest price and a straw that is certain to be in the cap.
Specifications
Common questions
Which materials does the listing allow?
The compatible-material line says rubber, plastic, wood, vinyl and metal.
Do reviewers use it on uPVC?
Yes. The review set includes sticking PVC doors, window runners, patio rails and locks.
Is a straw always in the box?
Not in the reviews. Several people say the straw was missing or would not stay in the nozzle.
This 3-IN-ONE listing is about £91.90 and the page does not agree with itself. The title says a pack of 2, while the included-components line and the volume block say 12 × 400 ml, 4,800 ml and 4.39 kg. The star line is 4.6 from 2,383 reviews, the same count as the single 400 ml can, and the 50 texts in the saved listing read as that single can rather than comments on a case. Materials on the spec line are metal, rubber and vinyl, with plastic and wood also in the bullets. Until you have confirmed how many cans will arrive, a price per can could be about £46 or about £7.66, and this file cannot finish that sum. Leave the row unless the live basket states one pack count in one place.
Pros
Cons
Best for: Only a buyer who has confirmed the can count on the live amazon.co.uk page before paying about £91.90.
Less suitable: Anyone comparing shelf prices, or a household that wants one 400 ml can.
Specifications
Common questions
Is this a 2-pack or a 12-pack?
The title says pack of 2. Number of items, packs and included components all say 12 × 400 ml.
Are the reviews about the case?
The 50 texts in the saved listing match the single 400 ml listing, not comments on a 12-can case.
What materials are on the spec line?
Metal, rubber and vinyl. The bullets also name plastic and wood.
Everbuild SILSPRAY is a 400 ml dry silicone lubricant at about £8.00, rated 4.6 from 67 reviews, and a bullet names mould making and release as well as windows, doors and home hardware. The eight review texts in the file are short: a garage door, metal hinges and a curtain track, with no repeated fault described. Origin is listed as the United Kingdom and the container is a tin of 0.4 litres. There is no temperature and no water-resistance line. Sixty-seven reviews is a modest count next to 615 on Soudal SP400 and 2,383 on 3-IN-ONE, so the 4.6 does not carry the same weight. Choose it when you want a dry-silicone claim on a mid-price 400 ml can. Look elsewhere if you need a large review sample or a stated temperature.
Pros
Cons
Best for: Hinges, a garage door or a light mould-release job when you specifically want a dry-film claim at about £8.00.
Less suitable: A buyer who wants either the lowest price with 615 reviews or the only stated 250 °C line.
Specifications
Common questions
Does the listing call it a dry spray?
Yes. A bullet says it is a dry silicone lubricant.
Is mould release mentioned?
Yes. A bullet names mould making and release.
What do the eight reviews say?
They are short. Uses named are a garage door, metal hinges and curtain track. No repeated fault is described.
Fuchoi C035uk is a water-based mould release at about £8.99, rated 4.6 from 25 reviews, and the material line includes water, additives, a hydrophobic agent and silsesquioxanes. The bullets describe resin, candle and soap moulds, not a hinge aerosol, and the application line is to shake, spray from 6–8 inches, brush the coat even, and wait about 60 seconds. Several reviewers describe two bottles, one spray cap and a brush, while the title says 200 g, so the pack you picture may not match the box. The date-first-available line is 12 March 2026, a short sales history next to the Soudal and 3-IN-ONE cans. Use it to help resin, candles or soap leave a silicone, metal, polyester, concrete or plastic mould. Do not buy it to free a uPVC lock.
Pros
Cons
Best for: Demoulding resin, candle or soap from a mould you can brush.
Less suitable: uPVC hinges, locks, rubber door seals and any job that needs a solvent silicone film.
Specifications
Common questions
Is this the same as a workshop silicone aerosol?
No. The material line includes water, and the bullets describe mould release for resin, candles and soap.
How does the listing say to apply it?
Shake, spray from 6–8 inches, brush it even, and allow about 60 seconds to dry.
What pack do reviewers describe?
Several say two bottles, one spray cap and a brush. The title says 200 g.
The black Soudal three-pack is also 1,200 ml, at about £13.58, with 4.6 from 11 reviews and no review texts in the file. The compatible-material line is wide: fabric, glass, jewellery, leather, metal, paper, plastic, porcelain, stone and wood. That list is catalogue breadth, not a record that each surface was tried, and jewellery or paper is a strange reason to buy a solvent aerosol. The other three-pack is clear at about £13.69, so colour is the practical difference on the page, not a large price gap. Eleven ratings without comments is still a small sample next to 615 on the single SP400. It is a black-labelled spare-can buy if you already use this spray, and a weak first purchase if you wanted to read how it behaved on a door.
Pros
Cons
Best for: A repeat buyer who wants three black-labelled 400 ml cans and has already used the spray.
Less suitable: A first purchase, or a job where you needed review comments on hinges or seals.
Specifications
Common questions
How does this differ from the other three-pack?
This listing’s colour field is black. The other three-pack’s colour field is clear. Prices are about £13.58 and about £13.69.
Which materials are listed?
Fabric, glass, jewellery, leather, metal, paper, plastic, porcelain, stone and wood.
Are there review texts?
No. The star line is 4.6 from 11 reviews, and the saved listing has no review bodies.
Soudal SP400 is a single 400 ml aerosol at about £6.46 on amazon.co.uk, with 4.5 from 615 reviews, and the bullets say the can sprays at any angle. Several of the 50 reviews praise an attached nozzle, and others say the straw was missing or would not fit. You should check the cap before you try to lay a thin line along a seal. The technical block prints a one-hour cure-time field, which is catalogue language on a solvent aerosol, not a bead that skins like bathroom silicone. The surface line runs from pipe and brick to bath, worktop, sink and window, and there is no temperature figure. Among the single 400 ml cans here it is the best value, because the shelf price is the lowest and the review count is large enough for the straw complaint to show up more than once.
Pros
Cons
Best for: A first 400 ml can for hinges and window hardware when you want the lowest shelf price with several hundred reviews.
Less suitable: A job that needs a stated temperature, a guaranteed straw, or a water-based mould release.
Specifications
Common questions
Does the listing say it sprays upside down?
The bullets say the aerosol can be used at any angle (360 degrees).
What surfaces does the listing name?
The surface line lists pipe, door, brick, bathtub, countertop, sink and window.
Do the reviews mention the straw?
Yes. Several of the 50 reviews praise an attached nozzle, and others say the straw was missing or would not fit.
Two 400 ml Soudal aerosols are listed as 800 ml together at about £9.91, so you are paying about the price of one 3-IN-ONE can for two tins if both are the fill the title states. The star line is 4.3 from 19 reviews, and the saved listing holds only four short positive texts, which is too small a sample to show a recurring fault or a recurring success. The listing names fabric, glass, metal, plastic and rubber, and the water-resistance field says waterproof. Viscosity is low and the colour field is black. You are buying a spare can beside the one in use, not a better-documented product than the single SP400 at about £6.46 with 615 reviews. Leave it if you wanted review detail rather than a second tin.
Pros
Cons
Best for: A spare 400 ml Soudal can as well as the one you will open, once you accept a thin review file.
Less suitable: A first can, if you want hundreds of reviews before you trust the straw and the film.
Specifications
Common questions
What is the total volume?
The unit count is 800 ml, from two 400 ml cans.
Which materials are listed?
Fabric, glass, metal, plastic and rubber.
How many review texts are in the saved listing?
Four. They are short and positive. The star line says 19 reviews.
Ten amazon.co.uk silicone spray 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 volume, a materials line, and a form that matches the job score higher. A title that disagrees with the pack count, or a millilitre field left blank, is deducted. Review outcome is 20 points. Reviews that name a hinge, a lock, a seal or a mould score higher than a star line with no review text. Value is 15 points, from the shelf price in GBP against a can whose size is stated. The lowest price per tin does not win when the review file is empty or the pack count is unresolved. The highest score is the top pick. The best price among single 400 ml cans that still have several hundred reviews is the best value. One of each. A waterproof bullet is a listing claim, not a measured film. A temperature from another brand’s sheet is not copied onto a row that leaves the field blank. The one-hour field on a solvent aerosol is not a sealant cure. Prices are the amazon.co.uk shelf prices stored for 19 October 2026. This order is the listing score, not a laboratory test.

A silicone spray in this UK category is an aerosol that leaves a thin silicone film. It is used to cut friction and shed water on hinges, uPVC window gear, rubber seals, rails and light mould release. Shoppers are mostly householders with a stiff door or a squeaking lock, often after a window fitter named silicone rather than ordinary oil. Cartridge sealant, silicone grease in a tube and skin adhesive are not this category.
A cartridge does not film a hinge, and multi-purpose oil is the wrong film for rubber. Soudal and 3-IN-ONE both warn off paint. Soudal excludes brake drums and discs.
One 3-IN-ONE row is titled as a pack of 2 and also says 12 × 400 ml at about £91.90. The Soudal five-pack does not state millilitres per can. Confirm the live page before you treat either as a bargain.
Use a thin film and wipe. Do not copy −40 °C to +200 °C from a Soudal or 3-IN-ONE sheet onto a listing that leaves temperature blank. Liqui Moly 3310 is the only row here with a printed upper rating, 250 °C.
A solvent aerosol is for hardware and rubber. A heavier grease is for loaded metal. A penetrant is for a seized thread. A water-based release is for resin and candles. 3-IN-ONE and Soudal name rubber, plastic and light metal, and both warn off paint. Soudal’s sheet excludes brake drums and discs. 3-IN-ONE excludes pedals and steering wheels. Reviewers of Soudal SP400 and 3-IN-ONE repeatedly mention a straw that is missing, loose or hard to aim. Soudal’s sheet says spray from about 20 cm.
Soudal’s UK sheet of 20 April 2022 and the 3-IN-ONE professional sheet both state −40 °C to +200 °C. Those amazon.co.uk rows in this set leave temperature blank, so the sheet figure is not written into the table. Liqui Moly 3310 states 250 °C as an upper rating only. Everbuild’s file has no temperature line. Reconcile pack count with the technical block: the about £91.90 3-IN-ONE row says 2 in the title and 12 × 400 ml in the spec, and the five-pack does not state millilitres.
Three typical situations, each with a recommendation from this comparison.
You want a thin film on sticking PVC doors, window runners, patio rails and locks, and the largest review sample on a single 400 ml can. 3-IN-ONE is the top pick: about £9.78, 4.6 from 2,383 reviews, with rubber, plastic, wood, vinyl and metal named. Several reviews say the straw was missing. There is no temperature on this listing.
You want a stated temperature for door rubbers, sunroof channels and plastic panels, and you will stay off brakes and pedals. Liqui Moly 3310 is 300 ml at about £10.95, 4.6 from 3,287 reviews, with an upper rating of 250 °C. Reviews say there is no long nozzle. Many of those texts are not UK reviews.
You need a water-based release for resin, candles or soap, not a workshop aerosol on a hinge. Fuchoi is about £8.99, 4.6 from 25 reviews. The bullets say shake, spray from 6–8 inches, brush, and wait about 60 seconds. The title says 200 g. Reviewers describe two bottles, a cap and a brush.
The top pick is the 3-IN-ONE 400 ml silicone spray at about £9.78: 4.6 from 2,383 amazon.co.uk reviews, with rubber, plastic, wood, vinyl and metal named, and reviews that cover PVC doors, runners, patio rails and locks. The straw is missing or loose in several reviews, and this listing has no temperature figure. The best value is Soudal SP400 at about £6.46, a single 400 ml can at 4.5 from 615 reviews. That is the lowest single-can price here with several hundred reviews. The bullets say it sprays at any angle. Straw complaints show up more than once, and the one-hour field is not a sealant cure. This order is the listing score, not a laboratory test.
Soudal SP400
Best price among single 400 ml cans that still have several hundred reviews: about £6.46, 4.5 from 615 reviews.
