Introduction

Selleys has been solving tough sealing jobs for over 80 years. This guide compares two aerosol roof and gutter sealants from the Selleys range: Ezi Press Roof & Gutter (marketed as "Roof & Gutter Silicone") and Roof and Gutter Spray Seal. Both products target the same application area and share an aerosol delivery format, but they differ significantly in chemical composition, flammability characteristics, and safety requirements. Those differences directly affect job-site safety protocols, storage constraints, and regulatory compliance. This comparison draws exclusively from the manufacturer's safety data sheets to help specifiers and applicators choose the right product for their working conditions.

At-a-glance comparison table

Application format

Both products use an aerosol delivery system. The propellant chemistry, however, creates two very different safety profiles.

Roof & Gutter Silicone (Ezi Press)

The Ezi Press datasheet describes this product as a "sealant packed as an aerosol." It uses a fluorinated propellant — trans-1,3,3,3-tetrafluoroprop-1-ene — at a low 1–2.5% concentration. The product carries a Dangerous Goods Class 2.2 rating: a non-flammable, non-toxic gas. That low propellant concentration and non-combustible chemistry mean the product carries only standard aerosol warnings (H229: pressurized container may burst if heated). No precautions against ignition sources are required. It's a straightforward safety profile.

Roof & Gutter Spray Seal

The Spray Seal datasheet describes it as a "roof and gutter sealant packed as an aerosol." It uses a hydrocarbon propellant blend totalling 30–90% of the formulation by weight: butane (10–30%), propane (10–30%), and cyclohexane (10–30%). This puts the product in Dangerous Goods Class 2.1 — a flammable aerosol — and triggers a Category 1 aerosol classification. The datasheet mandates precautionary statements P210 ("Keep away from heat/sparks/open flames/hot surfaces. No smoking") and P211 ("Do not spray on an open flame or other ignition sources"). Neither of those requirements applies to the Ezi Press product.

Both products deliver sealant via aerosol. The Spray Seal's higher propellant load and flammable chemistry require hot-work permits and ignition-source controls. The Ezi Press formulation does not. Know your site before you choose.

Propellant and chemical composition

The propellant systems are the sharpest technical distinction between these two products.

Roof & Gutter Silicone (Ezi Press)

The Ezi Press datasheet lists one reportable ingredient: trans-1,3,3,3-tetrafluoroprop-1-ene (CAS 29118-24-9) at 1–2.5% w/w. The balance is described as "ingredients determined to be non-hazardous or below reporting limits." This fluorinated propellant (HFO-1234ze) is a low-global-warming-potential alternative to traditional hydrocarbons and is non-flammable by design. The minimal disclosed chemistry points to a leaner formulation with fewer reportable hazardous substances — less paperwork, cleaner safety documentation on site.

Roof & Gutter Spray Seal

The Spray Seal datasheet discloses four reportable chemicals totalling 31–100% of the formulation: butane (10–30%), cyclohexane (10–30%), propane (10–30%), and naphtha petroleum hydrotreated heavy (1–10%). All four are flammable hydrocarbons. Cyclohexane and naphtha also contribute to the product's skin irritation (H315), eye irritation (H319), and narcotic effect (H336) classifications — none of which appear on the Ezi Press sheet.

The Ezi Press uses a modern, low-hazard propellant at minimal concentration. The Spray Seal relies on a hydrocarbon propellant system that introduces flammability and additional health considerations. Those characteristics may deliver different spray performance or solvency for the sealant resin, but they also demand a higher level of site management.

Hazard and safety profile

Hazard classifications determine PPE requirements, ventilation needs, and emergency response procedures.

Roof & Gutter Silicone (Ezi Press)

The Ezi Press datasheet states the material is "not classified as hazardous according to criteria of Safe Work Australia GHS 7" beyond its physical form as a pressurized container. The signal word is "Warning" — the lower of the two GHS tiers. The sole hazard statement is H229 (pressurized container risk). The datasheet specifies PPE as safety shoes, overalls, gloves, and safety glasses, with natural ventilation typically adequate. The Hazchem code is 2YE and the Initial Emergency Response Guide number is 49.

Roof & Gutter Spray Seal

The Spray Seal datasheet states the material "is hazardous according to health criteria of Safe Work Australia." It carries a "Danger" signal word — the highest GHS tier. Five hazard statements apply: H223 (flammable aerosol), H229 (pressurized container), H315 (skin irritation), H319 (serious eye irritation), and H336 (narcotic effects). The datasheet mandates protective gloves, protective clothing including eye/face protection, and a suitable respirator, and requires use "only outdoors or in a well-ventilated area" (P271). For first aid involving skin or eye contact, the Spray Seal datasheet prescribes continuous 15-minute flush procedures and advises calling a poison centre if feeling unwell (P312) — instructions that don't appear in the Ezi Press sheet.

The Ezi Press keeps your safety setup simple: standard PPE, natural ventilation, no respirator. The Spray Seal requires respiratory protection, enhanced ventilation, strict ignition control, and more intensive first-aid protocols. Confined spaces, hot-work zones, or sites with limited PPE availability are a clear fit for the Ezi Press.

Storage and transport requirements

Both products share aerosol-specific storage precautions, but flammability classification changes your regulatory obligations.

Roof & Gutter Silicone (Ezi Press)

The Ezi Press datasheet specifies storage in a cool, dry, well-ventilated place out of direct sunlight, with temperatures not exceeding 50°C (P410+P412). As a Division 2.2 product (non-flammable gas), the datasheet states it "must be stored in accordance with the relevant regulations" but does not require separation from ignition sources. The product code is 100628 (barcode 9300697125859).

Roof & Gutter Spray Seal

The Spray Seal datasheet sets the same temperature ceiling (50°C maximum, P410+P412) but adds mandatory precautions for flammable goods: keep away from heat, sparks, open flames, and hot surfaces; no smoking (P210). Storage must be in a well-ventilated place with the container tightly closed (P403+P233) and locked up (P405). As a Class 2.1 flammable gas, this product faces stricter segregation and quantity limits in shared storage facilities under the Australian Dangerous Goods Code. The product code is 100851 (barcode 9300697127310).

Both products share the same temperature sensitivity. The Spray Seal's flammable classification adds ignition-source separation, locked storage requirements, and potentially reduced allowable quantities in multi-tenant warehouses.

Cure chemistry and substrate details

Neither supplied safety datasheet provides technical performance specifications — and it's worth understanding what that means for your planning.

The Ezi Press and Spray Seal datasheets focus exclusively on hazard communication and safe handling under GHS/Safe Work Australia frameworks. Information on cure mechanism (moisture-cure, solvent-evaporation, etc.), open time, tack-free time, full-cure duration, substrate adhesion (metal, tile, concrete, etc.), and specific repair applications (leak sealing, flashing attachment, etc.) does not appear in the documents provided. For those details, consult the separate product technical datasheets or the manufacturer's application guides, which were not included in this comparison package.

When to choose Roof & Gutter Silicone (Ezi Press)

Choose this product when:

1. Working in ignition-controlled or confined environments. The Ezi Press datasheet confirms a non-flammable propellant (Dangerous Goods Class 2.2) with no H223 flammability classification. That makes it viable near active HVAC equipment, electrical panels, or in indoor settings where flammable aerosols are off the table.

2. Keeping PPE and ventilation requirements lean. The datasheet specifies standard PPE — safety shoes, overalls, gloves, safety glasses — with natural ventilation typically adequate. No respirator, no forced ventilation. That means less setup time and a cleaner compliance picture compared to the Spray Seal's respiratory and enhanced-ventilation requirements.

3. Streamlining hazard communication and safety training. The "Warning" signal word and single-hazard classification (pressurized container only) make safety inductions faster and reduce regulatory documentation. Compared to the Spray Seal's "Danger" rating and five-hazard profile, this is a much simpler safety story to communicate across a team.

When to choose Roof & Gutter Spray Seal

Choose this product when:

1. Cure speed or solvency matters and flammability can be managed. The supplied datasheet does not detail cure kinetics. However, the higher solvent content — cyclohexane (10–30%), naphtha (1–10%) — suggests potential for faster solvent flash-off or stronger wetting of contaminated substrates. To get that performance, the job site must enforce P210/P211 ignition controls and P271 ventilation requirements as documented in the datasheet.

2. The job is outdoors or in open-air conditions. The Spray Seal datasheet mandates "use only outdoors or in a well-ventilated area" (P271). That requirement fits naturally with typical roof repair work. When the job is already exterior-based with no ignition sources nearby, the product's flammability and narcotic-effect warnings become far easier to manage in practice.

3. Procurement or availability favours hydrocarbon-propellant formulations. The datasheet confirms a traditional butane/propane propellant system (30–90% combined). This may offer procurement or availability advantages over the Ezi Press's specialised fluorinated propellant, though the datasheet itself provides no pricing information.

Summary

Selleys produces two aerosol roof and gutter sealants with distinct safety profiles suited to different working conditions.

The Roof & Gutter Silicone (Ezi Press) uses a low-concentration fluorinated propellant that keeps the product non-flammable (Dangerous Goods Class 2.2) and straightforward to handle. Standard PPE and natural ventilation are all you need, according to its safety datasheet. The Roof & Gutter Spray Seal uses a high-concentration hydrocarbon propellant blend that makes it a flammable aerosol (Class 2.1) with additional skin, eye, and narcotic hazard classifications. It requires respiratory protection, enhanced ventilation, and ignition-source controls.

Neither datasheet discloses cure chemistry, substrate adhesion data, or repair-specific guidance. Product selection comes down to your job-site safety constraints. Use the Ezi Press in confined spaces, hot-work zones, or environments where a streamlined PPE setup is essential. Use the Spray Seal on outdoor applications where flammability protocols are already in place and a solvent-heavy formulation may deliver performance benefits not quantified in the safety literature.

Related Products & Brand Context

This guide covers two products from Selleys that sit within the same narrow category — Roof & Gutter Silicone and Roof & Gutter Spray Seal — both designed to seal leaks in roofing and guttering systems. The 'Related Products & Brand Context' section should not attribute tube-based product specifications (caulking gun requirement, ±25% movement capability, 25-year guarantee, 15 colour options, specific substrate compatibility list) to the Ezi Press aerosol product. These specifications belong to the separate Selleys Roof & Gutter Silicone cartridge/tube product. The section should either be removed, clearly labelled as describing a third related product (not one of the two being compared), or corrected to avoid implying the Ezi Press aerosol carries these specifications. Roof & Gutter Spray Seal, by contrast, is packaged as an aerosol and is positioned as a faster, lower-technique option — particularly useful when working on wet surfaces where traditional sealants may not adhere as readily.

From a use-case adjacency perspective, someone applying either of these products is likely to also need surface preparation supplies such as a cleaner or degreaser to ensure the substrate is free of dirt, moss, or loose material before sealing. For Roof & Gutter Silicone specifically, a caulking gun is a required applicator tool. Depending on the extent of the repair, users may also reach for a roof primer or a compatible flashing tape to address larger gaps before applying a silicone bead.

In terms of category position, Roof & Gutter Silicone is the more precision-focused, durability-oriented choice within this sibling pair, while Roof & Gutter Spray Seal prioritises accessibility and speed. Choosing between them depends primarily on the scale of the job, the condition of the surface, and how much application control the user needs.
