Made by Selleys, a division of DuluxGroup Australia Pty Ltd, it's designed for the real conditions Australian and New Zealand exteriors throw at buildings year-round.\n\nThe 500g format suits both trade professionals and DIY users who want a ready-to-use product with no mixing fuss. Interior fillers aren't built for this kind of work — this formulation is, handling the thermal and environmental stresses that exterior surfaces deal with constantly.\n\n---\n\n## Physical characteristics and what they mean\n\nKnowing how this filler behaves physically means you'll apply it with confidence and won't be caught off guard at any stage of the job.\n\n### Form and colour\n\nThe filler comes as a grey paste. Grey is standard for masonry repair because it sits close to the natural tone of concrete, render, and mortar. On unpainted surfaces, repairs blend in without much fuss. On painted surfaces, paint over the cured repair and you're done.\n\n### Specific gravity\n\nSpecific gravity sits between 1.01 and 1.05 — just marginally denser than water. For a filler, that means good workability and easy application. The lightweight formulation won't slump in deep or vertical cracks, so you get clean, controlled results.\n\n### Viscosity\n\nAt 6,000 to 9,000 Poise (P), this is a firm, workable paste. It stays where you put it on vertical and overhead surfaces without running or sagging, while still pressing easily into cracks and smoothing flush. That's the viscosity range that gets professional results on masonry repair.\n\n### Odour\n\nThe product has a characteristic odour typical of paste-based fillers. It's not a heavily solvent-based formulation, but good ventilation during application is always worth doing.\n\n---\n\n## Key technical features\n\n### Non-combustible formulation\n\nThis filler won't ignite or contribute to fire under normal conditions of use and storage. On exterior building surfaces — often near electrical conduits, gas meters, or other infrastructure — that's a real practical advantage. Storage is also straightforward, with no flammable materials requirements to deal with.\n\n### Thermal stability\n\nAustralian and New Zealand exteriors are hard on surfaces — intense summer heat, cold overnight temperatures, and everything between. This formulation holds its structural integrity through that full range without cracking, shrinking, or softening. The repair stays solid long after the job is done.\n\n### Chemical stability\n\nUnder normal storage and use conditions, this product won't degrade, separate, or react in ways that undermine performance. Seal it properly, store it correctly, and it stays in working condition.\n\n---\n\n## Suitable surfaces and applications\n\nThis product is formulated for exterior brick and render surfaces — the most common masonry substrates on Australian residential and commercial buildings.\n\n**Brick surfaces:** Settlement, thermal movement, and moisture ingress all cause cracks in mortar joints or through the face of bricks. This filler handles surface crack repair in those areas reliably.\n\n**Render surfaces:** Render over brick or block walls expands and contracts with every temperature cycle, making surface cracking one of the most common maintenance issues on Australian homes. This filler restores a continuous surface and stops water getting in before it becomes a bigger problem.\n\nThis product is for surface crack repair. Where cracks point to significant structural movement or building defects, get a professional structural assessment — no filler substitutes for that.\n\n---\n\n## Application guidance\n\n### Preparation\n\nGood preparation makes the difference between a repair that lasts and one that fails in the first season. Before applying:\n\n- Brush or vacuum out all loose material, dust, and debris from the crack.\n- Make sure the surface is clean and free from oil, grease, or loose paint.\n- The surface should be slightly damp but not wet — a completely dry or saturated surface reduces bond strength.\n- Widen very fine hairline cracks slightly with a scraper or crack tool so the filler has something to grip.\n\n### Application method\n\nApply the filler directly to the crack using a filling knife or putty knife. Press the paste firmly into the crack — full contact, no air pockets. Overfill slightly to account for minor shrinkage during drying. Once set, sand back flush with the surrounding surface.\n\nFor deeper cracks, build up in layers rather than filling in one go. Let each layer dry before applying the next. This eliminates surface cracking caused by differential drying rates between the outer skin and the interior of a deep fill — and it's what gets you a lasting result.\n\n### Finishing\n\nOnce fully cured, sand the repaired area smooth and paint to match the surrounding surface. On unpainted masonry, the grey tone matches most render and mortar finishes straight from the container.\n\n---\n\n## Storage instructions\n\nStore in cool, dry, well-ventilated conditions away from direct sunlight. Heat and sun exposure will dry out the paste prematurely in the container, cutting workability and shelf life short. After every use, seal the lid tightly.\n\nUnventilated sheds and vehicle boots in summer are not suitable storage environments — temperatures in those spaces can climb well above normal ambient levels.\n\n---\n\n## Safety considerations\n\n### Skin sensitisation\n\nThis product is classified as a Skin Sensitiser Category 1 under the Globally Harmonised System (GHS) of chemical classification, carrying hazard statement H317 — May cause an allergic skin reaction. This is the most important safety consideration for every user.\n\nSensitisation builds with repeated or prolonged skin contact, and once it develops, even minor future exposure can trigger a reaction. That applies to trade professionals using the product regularly and to DIY users who may not realise how cumulative sensitisation works. Protect yourself from the start.\n\n**Required PPE:**\n- Nitrile gloves — the right choice here; latex gloves don't provide adequate protection against the sensitising agents in this formulation\n- Safety glasses — protection against splashes during application\n- Overalls — to keep skin contact on arms and body to a minimum\n- Safety shoes — standard footwear protection for any construction-adjacent task\n\n### Dust precautions\n\nSanding cured filler generates fine particulate matter. Don't breathe the dust. Use a dust mask rated P2 minimum when sanding, and work outdoors or in a well-ventilated area wherever possible.\n\n### First aid procedures\n\n**Skin contact:** Remove contaminated clothing immediately. Flush the affected skin with running water for an extended period. If irritation or redness persists, seek medical advice.\n\n**Eye contact:** Wash eyes immediately and thoroughly with clean, running water, holding eyelids open during rinsing to ensure full flushing. Seek medical advice promptly if irritation continues.\n\n**Ingestion:** Do not induce vomiting. Seek medical attention. Keep the product container or Safety Data Sheet (SDS) on hand to show medical personnel.\n\n**Inhalation:** Move to fresh air immediately. If symptoms such as dizziness or respiratory irritation persist, seek medical advice.\n\n---\n\n## Transport and dangerous goods classification\n\nThis product is not classified as Dangerous Goods for transport by any of the following modes:\n\n- Road and rail (Australian Dangerous Goods Code)\n- Air (IATA Dangerous Goods Regulations)\n- Marine (IMDG Code)\n\nThis applies in both Australia and New Zealand. The product moves without special packaging, labelling, or documentation requirements — whether you're a trade professional restocking the van or a homeowner picking it up from the hardware store.\n\n---\n\n## Expert tips\n\n- **Don't apply in freezing conditions or when rain is imminent.** Frost or rain before the filler cures will undermine adhesion and shorten the life of the repair.\n- **Prime the repair area before painting**, particularly on porous render surfaces. Priming ensures an even paint finish and stops the repaired area absorbing paint at a different rate than the surrounding surface — that's the detail that separates a clean result from an obvious patch.\n- **For cracks wider than approximately 5mm**, use a foam backer rod as backing material. It reduces the volume of filler needed and improves long-term repair performance.\n- **Label partially used containers with the date opened.** It's a small habit that keeps you working with product in good condition and helps you get the most out of every container.\n\n---\n\n## References\n\n- Based on manufacturer specifications and Safety Data Sheet provided for Selleys No More Cracks Exterior
