Is this product classified as Dangerous Goods for transport? → No; not classified as Dangerous Goods by road, rail, air (IATA), or marine (IMDG) under Australian and New Zealand criteria --- ## Product Overview Selleys No More Cracks Exterior Brick & Render Filler is a grey paste compound for repairing cracks in exterior masonry — brick, render, and everything in between. Made by Selleys, a division of DuluxGroup Australia Pty Ltd, it addresses one of the most persistent maintenance headaches in Australian homes and buildings: exterior masonry that cracks from weathering, thermal movement, and gradual settling. Selleys has been around for over 80 years. This guide covers everything you need to get a solid result — what the product does, how it works, how to apply it, how to store it, and what safety precautions matter. --- ## What This Product Is and What It Does No mixing. No guesswork. Selleys No More Cracks Exterior Brick & Render Filler comes pre-mixed and goes straight from the container to the surface. It's built for **exterior masonry** — outdoor surfaces that face full sun, rain, temperature swings, and whatever else the Australian climate delivers. It works on: - **Brick surfaces**: Cracks in the face of bricks or in mortar joints - **Render surfaces**: Cracked or chipped render — the cement-based coating applied over brickwork or blockwork The grey colour is deliberate. It blends with the tone of most unpainted masonry and render, giving you clean results before any painting or finishing goes on. --- ## Key Physical Characteristics Understanding the physical properties of this filler means you know what to expect from first application through to the finished repair. ### Colour and Appearance Grey, with a characteristic odour. The paste consistency gives you control — apply it, shape it, and smooth it to a clean finish before it sets. ### Specific Gravity Specific gravity sits at **1.01–1.05**. That's just above water, which tells you the filler has a workable, paste-like body — not so runny that it slides out of a crack, and not so stiff that it fights you on application. ### Viscosity Measured at **6,000–9,000 Poise (P)**, this filler is thick enough to stay where you put it — including on vertical surfaces like rendered walls — without sagging or running before it sets. ### Thermal and Chemical Stability The formulation is **thermally stable** and **non-combustible**, with solid chemical stability under normal working conditions. For a product that lives on an exterior wall through Australian summers, UV exposure, and seasonal temperature swings, that stability matters. The cured filler won't soften, break down, or crack again from heat alone. --- ## Practical Applications and Use Cases This product is suited to both trade professionals and DIY users tackling exterior masonry repairs. It's the right choice for: - **Hairline and moderate cracks in rendered walls**: Render cracks as buildings settle and seasons drive thermal movement. Press this filler in, restore a smooth surface, and it's ready for repainting. - **Surface cracks in brick faces**: Where bricks have developed surface cracks — not structural failure — this filler delivers a clean, protective repair. - **Mortar joint repairs**: Minor surface deterioration of mortar joints on brick walls is well within scope. One important boundary: this product is for surface crack repair, not structural repairs. Wide, stepped, or recurring cracks that suggest structural movement need a qualified builder or structural engineer to assess them before any surface repair goes ahead. --- ## How to Apply the Filler Always read the manufacturer's instructions on the product label. The steps below reflect standard practice for this type of exterior masonry filler. ### Surface Preparation Preparation determines whether the repair holds. 1. **Clean the crack**: Remove all loose material, dust, and debris with a stiff brush or vacuum. 2. **Make sure the surface is dry**: Applying to a damp surface undermines adhesion and shortens the life of the repair. 3. **Remove flaking or unstable material**: The filler bonds to a sound substrate. Strip away any loose render or crumbling brick first. ### Application 1. **Apply directly from the container**: No mixing needed. Use a filling knife or putty knife to press the filler firmly into the crack. 2. **Overfill slightly**: Apply a small amount proud of the surface — filler shrinks a little as it cures. 3. **Smooth the surface**: Use a damp tool or finger to bring the filler flush with the surrounding surface before it starts to set. 4. **Let it dry fully**: Drying time varies with repair depth, temperature, and humidity. For deeper repairs, work in multiple layers — each one fully dry before the next goes on. ### Finishing Once dry, sand the repair smooth if needed, then prime and paint. Because the filler is grey, painting is the standard approach to a uniform finish, especially on coloured or previously painted surfaces. --- ## Storage and Care Instructions Store this product correctly and it'll be ready to use whenever you need it. - **Cool, dry, ventilated conditions**: Heat and humidity alter the filler's consistency and degrade performance. - **Away from direct sunlight**: UV exposure and heat will dry out the paste in the container. - **Lid sealed tightly after every use**: Air contact skins over the surface and eventually dries out the paste. Replace the lid firmly every time. - **Never let it freeze**: Freezing breaks down the formulation and destroys workability. --- ## Safety Considerations Read this before you start. ### Skin Sensitiser Classification This product carries a **Skin Sensitiser Category 1** classification and the hazard statement **H317 — May cause an allergic skin reaction**. Repeated or prolonged skin contact can cause sensitisation. Once sensitised, even minor contact can trigger a reaction. The practical implication: even if you've used this product before without any reaction, the risk builds with repeated exposure. Wear PPE every time, not just occasionally. ### Recommended Personal Protective Equipment (PPE) | PPE Item | Purpose | |---|---| | Nitrile gloves | Prevent skin contact with the filler | | Safety glasses | Protect eyes from splashes during application | | Overalls | Protect skin and clothing from contact | | Safety shoes | Protect feet if the product is dropped or spilled | ### Avoiding Dust Inhalation Avoid breathing dust — particularly during surface preparation, sanding dried filler, or cleaning out a crack. Use a P2 dust mask as a minimum when generating dust. ### First Aid Procedures If exposure occurs: - **Skin contact**: Remove contaminated clothing immediately. Flush the affected skin with running water for several minutes. Seek medical advice if irritation develops or persists. - **Eye contact**: Wash eyes immediately with clean, running water for at least 15 minutes. Seek medical advice promptly. - **Ingestion**: Do not induce vomiting. Seek immediate medical attention and bring the product container or label. - **Inhalation**: Move to fresh air immediately. Seek medical advice if dizziness, coughing, or breathing problems occur. ### Transport and Dangerous Goods This product is **not classified as Dangerous Goods** for transport by road, rail, air (IATA), or marine (IMDG) under Australian and New Zealand criteria. No special handling requirements apply. --- ## Expert Tips and Best Practices - **Work in moderate temperatures**: Apply when temperatures are between 10°C and 35°C. Extremes affect drying time and adhesion. - **Dampen deep cracks before filling**: A light mist of water inside a deep crack improves adhesion and slows initial drying slightly, which reduces shrinkage cracking. - **Use multiple thin layers for deep repairs**: Never fill a deep crack in one pass. Let each layer dry fully before adding the next — it reduces shrinkage and produces a more stable repair. - **Prime before painting**: Apply a suitable primer to the filled area before the topcoat. It locks in adhesion and gives you a seamless finish. - **Check repairs seasonally**: Exterior masonry moves. Inspect repaired areas each year — particularly after winter — and touch up where needed. --- ## Troubleshooting Common Issues ### The filler is cracking after drying Too much material was applied in a single pass. Let the first layer cure fully, then apply a second layer to address remaining depth or surface shrinkage. ### The filler is not adhering to the surface The surface was damp or dusty at the time of application. Strip out the repair, let the surface dry completely, clean away all dust and loose material, and reapply. ### The repaired area is visible after painting Sand the repair back to a smoother finish. An additional skim coat of filler before repainting may help. Always prime the filled area before the topcoat. ### The filler has dried out in the container This happens when the container is left unsealed or stored in warm or sunny conditions. Dried filler can't be reliably reconstituted. Seal the lid tightly after every use and store the product correctly. --- ## References - [Selleys No More Cracks Exterior Brick & Render – Selleys
