What is the maximum single-layer repair depth? → 6mm; deeper repairs require multiple layers, each fully dried before the next\n2. Can it be used on moving or active cracks? → No; it cures rigid and is not suitable where substrate movement occurs — use Selleys No More Gaps® instead\n3. What are the dry times? → Under 2mm: 2–3 hours; up to 6mm: 24 hours (at approximately 23°C and 50% relative humidity)\n\n---\n\n## Product Overview\n\nSelleys No More Cracks™ Large Cracks & Holes is a ready-to-use, water-based acrylic filler built for serious surface repair. When standard fillers fall short, this one steps up — engineered for cracks and holes that need real performance. Manufactured by DuluxGroup Pty Ltd under the Selleys name, it bonds well and shrinks minimally across a broad range of interior and exterior surfaces: plaster, mortar, concrete, timber, and primed metal.\n\nMost fillers handle hairline cracks and cosmetic touch-ups. This one handles the tough jobs — gaps and voids that need genuine body, reliable bonding strength, and the versatility to work across multiple substrates. Whether you're a tradie on site or a homeowner tackling a weekend repair, No More Cracks Large Cracks & Holes gets you a professional result the first time.\n\n---\n\n## Key Features and What They Mean in Practice\n\n### Water-based acrylic formula\n\nNo More Cracks Large Cracks & Holes uses a water-based acrylic formula, delivered as a smooth, workable paste. That means real advantages from the moment you open the tub:\n\n- **Ease of application:** The smooth paste consistency spreads evenly with a filling blade or scraper. Working material into deep or irregular voids takes less effort and delivers a cleaner result.\n- **Cleanup:** Clean tools and surfaces with water before the product dries — no solvents needed.\n- **Low odour:** Water-based formulas produce far less fume than solvent-based alternatives. Interior use stays comfortable without heavy ventilation.\n- **Paintability:** Once cured, the surface takes standard interior and exterior paints without lifting or reacting. Your topcoat goes on clean and stays put.\n\n### Superior adhesion with minimal shrinkage\n\nThese two properties define what this product actually delivers on the wall. Adhesion is how well the filler bonds to the surrounding substrate — poor adhesion means fillers that pop out, crack at the edges, or let the topcoat down when you paint over them. Shrinkage is how much the material contracts as it dries. All fillers shrink as moisture leaves, but excessive shrinkage in a large repair leaves a sunken, uneven surface, or pulls the filler away from the edges entirely.\n\nFor repairs up to 6mm deep, this product holds its bond and maintains its volume through the drying process. Less sink. Less likelihood of a second application. A solid result the first time.\n\n### Multi-surface compatibility\n\nNo More Cracks Large Cracks & Holes performs across the surfaces you actually work on:\n\n- **Plaster** — the most common interior wall substrate in Australian homes\n- **Mortar** — brick joints, render, and masonry repairs\n- **Concrete** — floors, walls, and structural surfaces\n- **Timber** — interior framing, skirting, architraves, and joinery\n- **Primed metal** — note the requirement for priming; bare metal is not a suitable substrate\n\nThat range of compatibility makes this a practical, single-product solution for whole-of-house repair work. One tub, multiple surfaces, no compromises on performance.\n\n---\n\n## Dry Times and Repair Depth\n\nGetting the dry time right is the difference between a repair that lasts and one that lets you down. Sand or paint too early and you undo the work. Here's what to plan for:\n\n| Repair Depth | Approximate Dry Time |\n|---|---|\n| Under 2mm | 2–3 hours |\n| Up to 6mm | 24 hours |\n\nThese times are based on standard conditions — approximately 23°C and 50% relative humidity. Cooler temperatures, higher humidity, or poor air circulation will extend dry times. Do not apply below 5°C. At that temperature, the acrylic cannot cure properly, which puts both adhesion and long-term stability at risk.\n\nFor repairs deeper than 6mm, build up the filler in multiple layers. Let each layer dry fully before applying the next. Filling a deep void in a single pass traps moisture beneath the surface — that leads to cracking and unpredictable dry times.\n\n---\n\n## Suitable Applications\n\n### Interior use\n\nNo More Cracks Large Cracks & Holes handles the full range of interior repair work where damage goes beyond a hairline crack:\n\n- Filling holes left by removed wall anchors, screws, or picture hooks that have enlarged over time\n- Repairing cracked or broken plaster around door frames and window reveals\n- Patching damaged sections of rendered interior walls\n- Filling gaps and cracks in timber joinery, skirting boards, and architraves before repainting\n\n### Exterior use\n\nThis product is rated for exterior use. To get the best results outdoors, follow these steps:\n\n- **Prime the surface first.** Exterior substrates, particularly concrete and masonry, need priming before application to ensure the adhesion holds.\n- **Protect from rain until painted.** The filler must be fully dry and painted over before exposure to rain or sustained moisture. A dried but unpainted filler on an exterior surface is not a finished, weather-resistant surface.\n- **Avoid exterior timber prone to excessive water absorption.** Timber that regularly saturates — horizontal surfaces exposed to pooling water, or highly porous species — is not a recommended substrate for this product outdoors.\n\n---\n\n## Limitations and When to Use a Different Product\n\nKnowing when to reach for a different product is part of getting the job done right. Here's where this product's limits sit.\n\n### Not suitable where movement occurs\n\nThis is the most important limitation to understand. No More Cracks Large Cracks & Holes cures to a rigid finish. It is not designed to flex or move with the substrate. Cracks caused by ongoing structural movement — seasonal expansion and contraction, building settlement, or vibration — will reopen through a rigid filler. For those situations, Selleys recommends No More Gaps®, a flexible sealant built to accommodate movement.\n\nIf you're not certain whether a crack is active (still moving) or static (historical damage that has stabilised), monitor it over several weeks before filling. Mark the ends of the crack with pencil and check whether the marks shift or the crack extends. Filling an active crack with a rigid product means the repair will not hold.\n\n### Temperature restriction\n\nDo not apply below 5°C. This applies to both the ambient air temperature and the surface temperature of the substrate. Cold surfaces prevent proper adhesion and curing. Wait for the right conditions.\n\n### Exterior timber with high water absorption\n\nTimber species or conditions where the wood absorbs significant amounts of water are not appropriate for this product outdoors. Repeated swelling and contraction from saturation stresses the bond and will cause the repair to break down prematurely.\n\n---\n\n## Application Guide\n\n### What you will need\n\n- Filling blade or scraper (a flexible filling knife works best for pressing material into voids)\n- Fine sandpaper (for finishing once dry)\n- Primer (for exterior surfaces and bare metal)\n- Clean water (for tool cleanup)\n\n### Step-by-step process\n\n**1. Prepare the surface.**\nRemove all loose material, dust, flaking paint, and debris from the crack or hole. The filler bonds to a clean, sound substrate — anything that compromises that surface puts the repair at risk. For exterior surfaces or primed metal, apply the appropriate primer and let it dry fully before you start.\n\n**2. Apply the filler.**\nUsing a filling blade or scraper, press the filler firmly into the crack or hole. Work the material in — don't just spread it across the surface. Full contact with the substrate walls and the base of the void is what gives you the adhesion and the lasting result.\n\n**3. Scrape off excess.**\nDraw the blade across the repair to remove excess filler and leave the surface as flush as possible. Less material sitting proud of the surface means less sanding once it's dry, and a cleaner finish.\n\n**4. Allow to dry fully.**\nRefer to the dry time table above. This step is non-negotiable. Sanding or painting over filler that hasn't fully cured drags the material, leaves an uneven surface, and puts the adhesion of your topcoat at risk. Let it dry.\n\n**5. Sand smooth.**\nOnce fully dry, sand with fine sandpaper until the repair sits flush with the surrounding surface. Wipe away dust before painting.\n\n**6. Paint.**\nApply your chosen topcoat. For exterior repairs, painting over the filler is essential — it provides the weather protection the filler itself does not offer. A painted repair is a finished repair.\n\n---\n\n## Available Formats\n\nNo More Cracks Large Cracks & Holes comes in four pack sizes to suit the scale of your job:\n\n- **230g Tub** — ideal for small, targeted repairs\n- **450g Tub** — a practical mid-size option for single-room projects\n- **1kg Tub** — suited to larger repair jobs or trade use where multiple repairs are planned\n- **230g Tottle** — a squeezable tube format that gives you more controlled dispensing for precise application, particularly useful for narrow cracks\n\nChoose the right pack size for the job. It reduces waste and keeps the product fresh. Once opened, store with the lid firmly sealed.\n\n---\n\n## Storage and Shelf Life\n\nStore in a cool, dry location away from direct sunlight and frost. Do not allow the product to freeze — freezing permanently alters the consistency and performance of the acrylic formula. After every use, close the lid or cap tightly to prevent the surface from skinning over or the product drying out in the container.\n\n---\n\n## Safety Considerations\n\nAs a water-based acrylic product, No More Cracks Large Cracks & Holes carries a lower hazard profile than solvent-based fillers. Standard precautions still apply:\n\n- Avoid prolonged skin contact; wash hands thoroughly after use\n- Keep out of reach of children\n- In case of eye contact, rinse immediately with water\n- Ensure adequate ventilation when working in enclosed spaces, even with low-odour water-based products\n\nFor full safety information, refer to the Safety Data Sheet (SDS) available from Selleys or
