Overhead work with a traditional tube sealant and caulking gun is awkward and imprecise at the best of times. This product pairs proven silicone chemistry with aerosol application to solve that problem directly.\n\nClassified as a \"sealant packed as an aerosol\" (SDS) and carrying product code 100628 under the Selleys division of DuluxGroup Australia (SDS), this is a specialist tool, not a general-purpose product. It's engineered for roofing maintenance and gutter repair where precision dispensing and immediate adhesion matter.\n\n## Technical specifications and composition\n\n### Chemical formulation\n\nThe active formulation contains Trans-1,3,3,3-tetrafluoroprop-1-ene at 1-2.5% by weight, with the balance comprising proprietary ingredients confirmed as non-hazardous or below reporting limits (SDS). This fluorinated propene is the aerosol propellant, chosen for its non-flammable properties and better environmental profile compared to traditional hydrocarbon propellants.\n\nThe silicone polymer matrix forms the sealing component that cures on contact with atmospheric moisture. Its non-hazardous nature in cured form means the safety documentation stays focused on practical, confident use (SDS).\n\n### Physical properties\n\nThe product comes in a 100g aerosol container (barcode 9300697125859) (SDS), delivering roughly 15–25 linear metres of bead depending on application thickness. Continuous propellant pressure means no pumping, no hand fatigue, and consistent bead width from first use to last.\n\nAs a pressurized container, it operates within specific temperature thresholds. Never expose it to temperatures above 50°C (SDS). That limit protects both the propellant system's vapour pressure characteristics and the structural integrity of the canister under heat.\n\n## Hazard classification and regulatory status\n\n### GHS classification\n\nUnder Australian GHS 7 criteria administered by Safe Work Australia, Selleys Ezi Press Roof & Gutter is not classified as a hazardous material based on the intrinsic properties of its chemical constituents (SDS). The low-toxicity silicone and propellant system perform reliably and safely when used as directed.\n\nThe product carries an Aerosols Category 3 classification with the signal word \"Warning\" and hazard statement H229: \"Pressurized container: may burst if heated\" (SDS). This addresses the physical nature of all pressurized aerosol systems, not chemical toxicity, and reinforces the importance of temperature control during storage and use.\n\nNo Poison Schedule classification applies under Australian therapeutic goods regulations (SDS), confirming that standard safety precautions are sufficient for consumer use.\n\n### Dangerous goods transport classification\n\nFor transport and regulatory compliance, the product is classified as Dangerous Goods Class 2.2, a non-flammable, non-toxic gas category (SDS). This classification governs transportation under both the Australian Code for the Transport of Dangerous Goods by Road & Rail and New Zealand NZS5433 standards (SDS).\n\nHazchem Code 2YE gives emergency responders immediate guidance on hazard type and appropriate response (SDS). Emergency Response Guide number 49 provides detailed incident management protocols for this specific dangerous goods classification (SDS).\n\n## Application guidelines\n\n### Surface preparation\n\nThe handling procedures confirm that normal use conditions require only natural air exchange for adequate ventilation (SDS). This product is designed for outdoor or well-ventilated environments, which is exactly where roofing jobs happen. Standard substrates including metal, tile, concrete, and EPDM need only to be clean and dry before application. On unfamiliar surfaces, run a test application on an inconspicuous area first to confirm compatibility.\n\n### Dispensing technique\n\nThe aerosol format gives you control that tube sealants can't match. Depress the valve with steady, consistent pressure and the propellant does the work. No squeezing, no plunger, no hand fatigue during long gutter runs or multiple roof penetrations. The result is cleaner beads and more consistent output.\n\nBecause the canister stays pressurized throughout its service life, bead width stays consistent from first use to final depletion. No uneven flow, no air pockets disrupting material delivery.\n\n### Coverage and yield\n\nThe 100g fill volume (SDS) delivers coverage that depends on bead dimensions. For typical roofing applications using a 5–6mm bead, expect roughly 15–20 linear metres per canister. Fine detail work with a narrower bead extends coverage further, while larger structural seals use material faster. Plan your job accordingly.\n\n## Storage requirements\n\n### Temperature controls\n\nStore in a cool, dry, well-ventilated location away from direct sunlight (SDS). The 50°C maximum storage temperature (SDS) is a firm limit. Exceed it and propellant vapour pressure can compromise container integrity, creating a rupture risk.\n\nIn Australian conditions, that threshold is reachable inside vehicles, sheds, or poorly ventilated storage areas during summer. Professional applicators should monitor storage area temperatures and move inventory during heat waves to stay well within the 50°C safety margin.\n\n### Container management\n\nKeep containers closed when not in active use and inspect regularly for propellant loss or valve issues (SDS). An aerosol canister's valve is its only barrier against material degradation and propellant escape, so treat it accordingly.\n\nStore away from foodstuffs (SDS) and incompatible materials detailed in Section 10 of the full safety documentation (SDS). Keep away from ignition sources and heat (SDS), standard practice for any pressurized container, even with a non-flammable propellant (Class 2.2) (SDS).\n\nAs a Division 2.2 Non-Flammable, Non-Toxic Gas under dangerous goods regulations (SDS), storage must comply with the relevant Australian and New Zealand regulations governing compressed gas products (SDS).\n\n## Personal protective equipment\n\n### Required protection\n\nThe prescribed PPE is safety shoes, overalls, gloves, and safety glasses (SDS). This combination covers the primary exposure routes: skin contact during application, eye exposure from overhead work, and foot protection on construction sites.\n\n### Glove selection\n\nNitrile rubber gloves are the recommended choice for intermittent contact with uncured sealant (SDS). Keep in mind that glove performance depends on thickness, quality, and the specific nitrile formulation, factors that vary between manufacturers. The documentation acknowledges this directly, noting that end-users should validate glove suitability for their specific working conditions (SDS).\n\nFor extended application sessions, double-gloving or rotating glove sets maintains barrier integrity. Uncured silicone can gradually permeate thin glove materials during prolonged contact.\n\n### Hygiene practices\n\nWash hands before smoking, eating, drinking, or using toilet facilities (SDS). This prevents inadvertent ingestion of uncured sealant residues that accumulate on hands during application. Wash contaminated clothing and protective equipment before storage or reuse (SDS).\n\n## Emergency response procedures\n\n### Inhalation exposure\n\nIf inhalation exposure occurs, remove the affected person from the area without creating additional casualties (SDS). This is particularly important in confined spaces or at height, where rescue requires proper training and equipment. Once clear, remove contaminated clothing and loosen remaining clothing (SDS).\n\nKeep the person comfortable, warm, and at rest until full recovery (SDS). If effects persist, seek medical advice (SDS). The low toxicity of both the propellant and silicone components means aggressive intervention is rarely needed, but always err on the side of caution.\n\n### Skin contact\n\nSkin or hair contact requires immediate removal of contaminated clothing and thorough flushing with running water (SDS). If swelling, redness, blistering, or irritation develops, get medical assistance (SDS). These symptoms indicate either allergic sensitization or prolonged contact, both of which warrant professional assessment.\n\n### Eye contamination\n\nEye contact requires immediate irrigation with water (SDS). Seek medical consultation after any eye contamination incident, regardless of apparent symptom severity (SDS). Eye tissue damage isn't always immediately visible, and prompt treatment delivers the best outcomes.\n\n### Ingestion\n\nIf ingested, rinse the mouth with water (SDS). Do not induce vomiting. Give the patient a glass of water to drink (SDS). Never give anything by mouth to an unconscious patient (SDS). If vomiting occurs naturally, provide additional water and seek medical advice (SDS).\n\nThe protocol against induced vomiting reflects the physical properties of silicone sealants: regurgitated material entering the respiratory tract can cause aspiration pneumonia. Providing water dilutes gastric contents and supports natural elimination.\n\n### Poison information access\n\nFor poisoning incidents, contact a physician or the Poisons Information Centre: 131 126 in Australia or 0800 764 766 in New Zealand (SDS). Have the product container or label on hand when seeking medical advice (SDS), as it gives treating physicians the precise formulation and hazard information they need.\n\n## Spill and release management\n\n### Small spill response\n\nSmall releases call for full protective equipment to prevent skin and eye contamination while avoiding gas inhalation (SDS). If it's safe to approach, isolate the leak source (SDS). Increase ventilation to disperse any propellant accumulation (SDS), especially important in partially enclosed work areas like attic spaces or covered porches.\n\nThe \"if safe to do so\" qualifier matters. Reaching an aerosol canister on unstable roofing or scaffolding may create greater hazards than the spill itself. Make the call based on actual conditions.\n\n### Large spill response\n\nMajor releases require clearing all unprotected personnel from the affected area immediately (SDS). Where safe access allows, isolate the leak source and increase ventilation to accelerate propellant dispersion (SDS). If the release reaches crops, sewers, or waterways, notify local emergency services straight away (SDS).\n\nThis environmental notification requirement reflects regulatory obligations under Australian and New Zealand environmental protection legislation. Chemical releases that may affect ecosystems or water quality must be reported, even when the released material is classified as non-hazardous.\n\n## Fire response\n\n### Suitable extinguishing media\n\nIf the product becomes involved in fire, water fog (or fine water spray where fog systems aren't available), alcohol-resistant foam, standard foam, dry agents (carbon dioxide or dry chemical powder) are all appropriate (SDS). This broad compatibility reflects the non-flammable nature of the propellant and the low combustibility of cured silicone.\n\n### Combustion hazards\n\nThe product is classified as combustible material (SDS). It won't readily ignite, but it will burn when exposed to sufficient heat. During burning or thermal decomposition, toxic fumes may be emitted (SDS). Firefighters must wear self-contained breathing apparatus and suitable protective clothing when any risk of exposure to vapours or combustion products exists (SDS).\n\nPredictable decomposition products include carbon monoxide, carbon dioxide, and potentially fluorinated organic compounds from propellant breakdown.\n\n## Best practices and expert guidance\n\n### Valve maintenance\n\n\"Do not pierce or burn, even after use\" (SDS) is more than a safety warning. The valve mechanism is what keeps the product ready to work, and disassembling or modifying it breaks the pressure seal. After each use, wipe the valve clean and replace the cap to prevent cured silicone from blocking it.\n\n### Temperature awareness during application\n\nStorage temperature limits are clear, but applicators working on dark roofing surfaces in summer need to think about surface temperature too. A metal roof can reach 65–70°C on a hot day, well beyond the 50°C canister limit (SDS). Keep the canister in shade or a cooled tool belt during application. Setting it directly on a hot roof surface is a risk that's easy to avoid.\n\n### Container disposal\n\nDisposal is listed as \"Pending manufacturer confirmation\" (SDS), meaning standard dangerous goods disposal protocols apply. Empty aerosol containers must not be incinerated or punctured (SDS), because residual pressure remains even in seemingly empty canisters. Dispose of through appropriate hazardous waste collection systems that handle pressurized containers.\n\n### Accessibility requirements\n\nKeep the product out of reach of children (SDS). In domestic settings, that means storage at height or in locked cabinets. On professional work sites, maintain sealant inventory in designated chemical storage areas with clear signage and controlled access.\n\n## References\n\n- Source PDF: SELLEYS_EZI_PRESS_ROOF___GUTTER-AUS_GHS.pdf (canonical)\n\n---\n\n## Frequently asked questions\n\nWhat is Selleys Ezi Press Roof & Gutter: A silicone sealant in aerosol format for roofing and guttering\n\nWhat is the product code: 100628\n\nWhat is the barcode: 9300697125859\n\nWho manufactures this product: Selleys, a division of DuluxGroup Australia\n\nWhat type of sealant is it: Silicone-based sealant\n\nWhat is the application method: Aerosol pressure system (no caulking gun required)\n\nWhat is the container size: 100g aerosol canister\n\nIs a caulking gun required: No\n\nWhat surfaces is it designed for: Roofing and guttering applications\n\nIs it a general-purpose sealant: No, it is a specialist roofing and guttering product\n\nWhat is the propellant used: Trans-1,3,3,3-tetrafluoroprop-1-ene\n\nWhat concentration is the propellant: 1-2.5% by weight\n\nIs the propellant flammable: No\n\nWhy was this propellant chosen: Superior environmental profile over hydrocarbon propellants\n\nIs the cured sealant hazardous: No\n\nIs the product classified as hazardous under Australian GHS 7: No\n\nDoes it carry any hazard classification: Yes, Aerosols Category 3\n\nWhat is the signal word: Warning\n\nWhat is the hazard statement code: H229\n\nWhat does H229 mean: Pressurized container may burst if heated\n\nIs the H229 classification about chemical toxicity: No, it relates to physical pressure hazard only\n\nDoes it have a Poison Schedule classification: No\n\nWhat is the dangerous goods transport classification: Class 2.2\n\nWhat does Class 2.2 mean: Non-flammable, non-toxic gas\n\nWhat is the Hazchem Code: 2YE\n\nWhat is the Emergency Response Guide number: 49\n\nWhat transport standards apply in Australia: Australian Code for Transport of Dangerous Goods by Road & Rail\n\nWhat transport standard applies in New Zealand: NZS5433\n\nWhat is the maximum storage temperature: 50°C\n\nWhat happens if stored above 50°C: Propellant pressure may compromise container integrity\n\nCan it be stored in a vehicle during Australian summer: No, temperatures may exceed 50°C\n\nHow should it be stored: Cool, dry, well-ventilated location away from direct sunlight\n\nShould it be stored near food: No\n\nShould it be kept away from ignition sources: Yes\n\nDoes the canister maintain consistent pressure throughout use: Yes\n\nDoes bead width stay consistent from first use to last: Yes\n\nWhat is the approximate coverage for a 5–6mm bead: 15–20 linear metres per canister\n\nWhat is the maximum estimated coverage: Approximately 25 linear metres for fine detail work\n\nWhat PPE is required: Safety shoes, overalls, gloves, and safety glasses\n\nWhat glove type is recommended: Nitrile rubber gloves\n\nAre nitrile gloves suitable for extended use: Validate suitability;

This product falls into the **Home & Garden > Sealants & Caulking** category, and more specifically within Selleys' roofing silicone line, as indicated by its placement at `selleys.com.au/products/sealants/roofing-silicone/`. Within that hierarchy, it is positioned as an outdoor, weatherproof sealant rather than a general-purpose or interior-grade product — a distinction that matters when choosing between sealants for different parts of a home.\n\nThe knowledge graph context for this product does not surface explicitly named sibling sealants from the Selleys range, so direct product-to-product comparisons within the Selleys sealant family cannot be drawn here. What is clear is that Roof & Gutter Silicone occupies a specialised niche: its neutral-cure, 100% silicone formula sets it apart from acetoxy-cure silicones or acrylic sealants that may not tolerate long-term UV exposure or metal substrates such as Colorbond as reliably.\n\nFor someone using this product, several adjacent product categories are worth considering. Because the sealant is applied to roofing, guttering, and flashing materials — including metals, PVC, and cement sheeting — surface preparation products such as primers or cleaners suitable for those substrates would typically be needed before application. A caulking gun is required for dispensing the cartridge, and masking tape is commonly used to achieve clean sealant lines around flashing joints and downpipe connections. For the solar pool heating and polycarbonate roofing applications this product supports, compatible fasteners or mounting hardware from related trade categories may also be relevant.\n\nIn terms of category position, Roof & Gutter Silicone is differentiated from general-purpose silicones by its 25-year durability guarantee, drinking-water approval, ±25% movement capability, and zero-slump formula — characteristics aimed at professional tradespeople and serious DIYers tackling outdoor weatherproofing rather than routine indoor gap-filling.\n<!-- nor-3601:relationships-end -->\n",
