What surfaces is Selleys Wet Area Silicone compatible with? → Ceramic and porcelain tiles, glass, stainless steel, metals, laminates, rubber, concrete, acrylic, and most plastics including PVC and ABS; not suitable for PE, PP, or PTFE\n2. How long does it take to fully cure and when can the area get wet? → Cures at approximately 2mm per 24 hours; a standard 6mm deep joint takes around 3 days, and the area must remain completely dry until fully cured\n3. Why choose neutral cure over standard acetoxy silicone? → Neutral cure releases alcohol rather than acetic acid, producing far less odour and avoiding corrosion or staining on metals, mirrors, and natural stone\n\n---\n\n## Product Overview\n\nSelleys Wet Area Silicone is a 100% neutral cure silicone sealant built for the toughest wet environments, where moisture, mould, and movement test every seal day after day. Engineered for bathrooms, kitchens, and laundries, it forms a fully waterproof, flexible seal that holds up where lesser sealants give out. Whether you're resealing a shower recess, finishing around a kitchen sink, or sealing tile joints in a laundry, this product delivers a durable, long-lasting result, backed by a 25-year guarantee against peeling or cracking.\n\nThis guide covers everything you need to select, apply, and maintain Selleys Wet Area Silicone with confidence, from understanding what neutral cure means in practice, to choosing the right colour, to knowing exactly when your seal is ready for water.\n\n---\n\n## What Makes This a Wet Area Sealant\n\nNot all silicone sealants are interchangeable. Selleys Wet Area Silicone is specifically formulated for environments that face regular water exposure, humidity, and temperature fluctuation, the very conditions that cause inferior sealants to crack, peel, shrink, or grow mould.\n\n### Neutral Cure Chemistry\n\n\"100% neutral cure\" describes the chemical process by which the silicone hardens. Neutral cure silicones release alcohol as a by-product during curing, not acetic acid, the vinegar-smelling compound released by acetoxy cure silicones. That distinction matters in two ways:\n\n1. **Surface compatibility:** Acetic acid can corrode or stain certain metals, mirrors, and natural stone. Neutral cure silicone works safely across a broader range of surfaces, giving you professional results without the risk of surface damage.\n2. **Odour:** Neutral cure products produce far less odour during application and curing, a real advantage when you're working in an enclosed bathroom or kitchen.\n\n### Mould Resistance\n\nSelleys Wet Area Silicone incorporates a fungicidal additive that actively inhibits mould growth within the silicone itself. This isn't surface-level protection, it's built into the material. In wet areas where mould is a persistent problem, this formulation directly extends the working life of your seal and cuts down on maintenance.\n\n### Non-Shrink, Non-Crack, Non-Peel\n\nThese three properties define the long-term performance of the cured sealant. Silicone that shrinks pulls away from surfaces and breaks the waterproof seal. Silicone that cracks lets water in. Silicone that peels loses adhesion and fails structurally. Selleys Wet Area Silicone is engineered to hold its bond and flexibility over time, and that's what the 25-year guarantee is built on.\n\n---\n\n## Surfaces and Compatibility\n\nKnowing where this sealant works, and where it doesn't, protects your surfaces and ensures a lasting bond.\n\n### Compatible Surfaces\n\nSelleys Wet Area Silicone bonds reliably to a wide range of common wet area materials:\n\n- **Ceramic and porcelain tiles** — the most common application surface in bathrooms and kitchens\n- **Glass** — including shower screens and splashbacks\n- **Stainless steel** — sinks, tapware surrounds, and appliance edges\n- **Metals (general)** — compatible with most metal surfaces found in wet areas\n- **Laminates** — kitchen benchtops and splashback panels\n- **Rubber** — seals around rubber components or fittings\n- **Concrete** — laundry floors, utility areas, and wet room substrates\n- **Acrylic** — bath surrounds and shower trays\n- **Most plastics** — including PVC and ABS commonly found in plumbing fixtures\n\n### Incompatible Surfaces\n\nThree plastic types are not suited to this product: PE (polyethylene), PP (polypropylene), and PTFE (polytetrafluoroethylene, commonly known as Teflon). These plastics have very low surface energy, so sealants simply cannot form a reliable bond with them. Applying silicone to these surfaces leads to poor adhesion and eventual seal failure. Know your surface before you start.\n\n### Surface Testing Recommendation\n\nFor plastics not listed above, the manufacturer recommends testing adhesion on a small, inconspicuous area before completing the full application. This is standard practice with any sealant when working on unfamiliar materials, a quick check that protects the quality of your finished result.\n\n---\n\n## Available Sizes and Formats\n\nSelleys Wet Area Silicone comes in two formats to match different project scales and application methods.\n\n### Cartridge — 300g\n\nThe 300g cartridge is the right choice for larger jobs, sealing an entire shower recess, bath surround, or multiple sink joints. It requires a caulking gun to dispense. Caulking guns are widely available from hardware retailers and deliver controlled, consistent bead application, which matters when you're working on long, continuous joints.\n\n### Tubes — 75g and 90ml\n\nThe smaller tube formats are built for minor repairs, touch-ups, or single-joint applications where a full cartridge would be more than you need. Tubes are squeezed by hand, so no caulking gun is required. The 75g and 90ml sizes cover limited linear meterage and are best reserved for targeted applications rather than full room sealing projects.\n\n---\n\n## Colour Options\n\nSelleys Wet Area Silicone is available in nine colours, so you can match or coordinate the sealant with your existing tile grout, fixtures, and surfaces. A well-matched sealant is less visually prominent and gives the finished installation a cleaner, more professional appearance.\n\n| Colour | Typical Use Case |\n|--------|-----------------|\n| Clear | Glass, transparent surfaces, or where the substrate colour should show through |\n| White | Standard white tiles, white fixtures, most bathrooms |\n| Off White | Slightly warmer white tiles and grout tones |\n| Ivory | Cream or ivory-toned tiles and fittings |\n| Light Grey | Light grey grout and contemporary tile schemes |\n| Mid Grey | Medium grey tiles and modern bathroom palettes |\n| Dark Grey | Dark tile joints and charcoal-toned bathrooms |\n| Charcoal | Near-black tile schemes and dark fixture surrounds |\n| Black | Black tiles, dark feature walls, and contrast applications |\n\nWhen in doubt, clear is a versatile choice that suits most surfaces without clashing.\n\n---\n\n## Application Guide\n\nFollow these steps and you'll achieve a clean, durable result.\n\n### Step 1 — Surface preparation\n\nSurface cleanliness is the foundation of a strong bond. Before applying Selleys Wet Area Silicone:\n\n- Remove all existing sealant completely. Old silicone prevents new silicone from bonding to the substrate, and there are no shortcuts here.\n- Clean the joint area thoroughly to remove soap scum, grease, mould, and dust.\n- Allow the surface to dry completely. Silicone applied to wet or damp surfaces won't cure correctly or bond reliably.\n\nWhen removing old silicone, a silicone remover product or a sharp blade gets the job done, followed by a wipe-down with methylated spirits or isopropyl alcohol to clear any remaining residue.\n\n### Step 2 — Cutting the nozzle\n\nFor cartridges, cut the nozzle at a 45-degree angle. The size of the cut determines the bead width, so match the nozzle opening to the width of the joint you're sealing. Cut tube tips the same way.\n\n### Step 3 — Applying the sealant\n\nApply the sealant in a single, continuous bead along the joint. Keep consistent pressure and speed to produce an even bead width. Avoid stopping and restarting mid-joint where possible, as this can create visible overlaps or gaps in the finished result.\n\n### Step 4 — Tooling the joint\n\nWithin 5 to 10 minutes of application, tool the bead smooth using a wet finger or a silicone spatula. This presses the silicone firmly into the joint for a stronger bond, produces a smooth, concave finish, and removes excess material.\n\nWet your finger or tool with water or a small amount of dish soap to stop the silicone from sticking during tooling. Work quickly. Once the surface skin begins to form, tooling becomes harder and can tear the bead. Keep your sections manageable and tool as you go.\n\n### Step 5 — Curing and water exposure\n\nSelleys Wet Area Silicone cures at approximately 2mm per 24 hours. A standard joint that is 6mm wide and 6mm deep takes around 3 days to cure fully through its cross-section. Thicker applications take proportionally longer. The area must stay dry until the sealant is fully cured.\n\nExposing the seal to water before full cure can wash out or disrupt the uncured silicone and undermine the seal's integrity. Plan your application timing so the area gets the full cure period before returning to use.\n\n---\n\n## Maintenance and Longevity\n\n### Routine cleaning\n\nOnce cured, the silicone surface handles standard bathroom cleaning products without issue. Avoid abrasive scrubbing pads or harsh solvent-based cleaners, as these can degrade the silicone surface over time and reduce the effectiveness of the built-in mould-resistant additive.\n\n### Monitoring the seal\n\nEven with a 25-year guarantee against peeling or cracking, a quick annual inspection is worth doing. Look out for discolouration or mould growth on the surface, lifting or separation from the substrate at the edges, and cracking or tearing in high-movement areas.\n\nSurface mould can often be treated with a mould remover product without replacing the sealant. Structural breakdown, such as lifting, cracking, or separation, means the old sealant needs to come out completely and the joint resealed properly.\n\n### When to reseal\n\nWhen a sealant has peeled away, cracked, or separated from the surface, resealing is essential to stop water getting in behind tiles, into wall cavities, or under flooring. Water damage in these areas is expensive to fix. Act when you first see the signs, because early resealing is always the more cost-effective move.\n\n---\n\n## Safety and Handling\n\n### During application\n\nKeep the work area well ventilated. Neutral cure silicone produces far less odour than acetoxy products, but good airflow during application and initial curing is still the right call. If silicone contacts skin, remove it with a dry cloth before it cures, then wash with soap and water. Keep the product out of reach of children during application and until fully cured.\n\n### Storage\n\nStore unused product in a cool, dry location away from direct sunlight and extreme temperatures. Seal cartridges and tubes after use. Cartridge nozzles can be plugged with a nail or purpose-made cap to stop exposed silicone from curing in the nozzle. Check the packaging for the specific expiry date.\n\n### Disposal\n\nDon't dispose of uncured silicone down drains. Allow any waste silicone to cure fully before disposing of it in general waste. Empty cartridges can be disposed of in line with your local council guidelines for hard plastics.\n\n---\n\n## Common Issues and Solutions\n\n| Issue | Likely Cause | Solution |\n|-------|-------------|----------|\n| Sealant not adhering | Surface was wet, greasy, or contaminated | Remove, clean thoroughly, allow to dry completely, reapply |\n| Mould appearing on surface | Surface mould from external contamination | Treat with mould remover; internal mould resistance remains fully intact |\n| Bead tearing during tooling | Tooling performed too late after application | Work in smaller sections; tool within 5 minutes of application |\n| Sealant skinning before tooling is complete | Hot or dry conditions accelerating cure | Work in shorter sections; tool immediately after each section |\n| Colour mismatch | Incorrect colour selected | Test colour in an inconspicuous area before full application |\n| Sealant not curing | Applied over existing silicone or incompatible surface | Remove fully, clean thoroughly, reapply to bare substrate |\n\n---\n\n## References\n\n- [Selleys Wet Area Silicone – Official Product Page, Selleys
