What is the maximum depth for a single application? → 6mm; repairs deeper than 6mm require multiple layers, each allowed to dry fully before the next 2. How long does this product take to dry? → 2–3 hours for repairs under 2mm; 24 hours for repairs up to 6mm, based on approximately 25°C and moderate humidity 3. Can this product be used on moving or expansion joints? → No — use Selleys No More Gaps® instead; this filler is not suitable for surfaces subject to ongoing movement --- ## Product Overview Selleys No More Cracks™ Large Cracks & Holes is a ready-to-use, water-based acrylic filler built for repairing large cracks and holes across a wide range of interior and exterior surfaces. Manufactured by DuluxGroup Pty Ltd under the Selleys name — backed by 80+ years of performance — it addresses one of the most common headaches in home maintenance: getting a smooth, durable repair that holds firmly, resists shrinkage, and accepts paint cleanly. Where other fillers struggle with larger voids or varied surfaces, this one handles plaster, mortar, concrete, timber, and primed metal without switching products. Whether you're a DIYer tackling a weekend repair or a tradesperson who needs consistent results across different job sites, No More Cracks Large Cracks & Holes is built to get it right the first time. --- ## Key Features and What They Mean in Practice ### Strong Adhesion Across Multiple Surfaces Adhesion — the filler's ability to bond firmly to the substrate without lifting, cracking at the edges, or separating over time — matters more for large repairs than for hairline cracks. A bigger repair carries more surface area under stress and more potential to fail. No More Cracks Large Cracks & Holes bonds to plaster, mortar, concrete, timber, and primed metal. That range of compatibility means one product handles the variety of surfaces found in a domestic or light commercial setting, from a damaged plasterboard wall to a chipped concrete step or a dented timber architrave. ### Minimal Shrinkage Shrinkage is the enemy of any filler repair. When a filler dries, water evaporates from the compound. If the formulation shrinks significantly during this process, the repair sinks below the surface — and you're back to applying additional coats and sanding before a smooth finish is achievable. In severe cases, shrinkage causes cracking within the repair itself. This product is formulated to minimise shrinkage, which matters most for larger repairs. A repair up to 6mm deep — the stated maximum for a single application — is a substantial void, and controlling shrinkage at that depth is a genuine technical advantage. Less shrinkage means fewer coats, less sanding, and a more reliable result. ### Water-Based Acrylic Formula The water-based acrylic composition has practical advantages at every stage: application, cleanup, and long-term performance. Water-based products carry lower VOC emissions than solvent-based alternatives, making them safer in enclosed or poorly ventilated spaces. Cleanup requires only water — no mineral spirits, no solvents. The smooth paste consistency works easily with standard filling tools. Acrylic binders also add some flexibility to the cured repair, helping the filled area resist minor movement without cracking. That said, this product is not designed for surfaces subject to ongoing or significant movement — see Limitations below. --- ## Available Formats No More Cracks Large Cracks & Holes comes in four packaging options: - **230g Tub** — suited to small, targeted repairs where minimal product is needed - **450g Tub** — the right choice for a handful of repairs in a single room or area - **1kg Tub** — the most economical option for larger projects, multiple repairs, or trade use - **230g Tottle** — a squeezable tube format for more controlled dispensing, particularly useful for repairs in tight spots or where keeping things neat matters Match the format to the scale of the job. For a single cracked wall, the 230g tub gets it done. For a renovation spanning multiple rooms or exterior repairs across a building façade, the 1kg tub keeps you working without stopping to reorder mid-project. --- ## Application Guide ### Surface Preparation Good surface preparation is the foundation of a repair that lasts. Before applying No More Cracks Large Cracks & Holes, the surface must be: - **Clean:** Remove dust, loose material, grease, and any existing filler that has lifted or lost adhesion. A stiff brush or vacuum clears loose debris from cracks; a damp cloth handles surface dust. - **Dry:** The substrate must be free of moisture. Applying filler to a damp surface undermines adhesion and extends drying time unpredictably. - **Sound:** The edges of the crack or hole must be firm. If the surrounding material is crumbling or soft, address the underlying cause before filling. For primed metal surfaces, confirm the primer is fully cured and intact before applying the filler. ### Application Method 1. **Load the filler onto a filling blade or scraper.** A flexible filling blade gives better control for feathering the edges of the repair flush with the surrounding surface. 2. **Press firmly into the crack or hole.** Firm pressure ensures the filler makes full contact with the substrate and eliminates air pockets — air pockets cause the repair to hollow out or crack after drying. 3. **Scrape off excess material.** Draw the blade across the surface at a low angle to remove surplus filler and leave the repair as close to flush as possible. This reduces the sanding required after drying. 4. **Allow to dry fully before sanding.** Use fine-grit sandpaper once dry. Sanding before full drying drags and smears the filler rather than cutting it cleanly. 5. **Prime and paint as required.** For best results — particularly on porous surfaces or exterior applications — prime the repair before applying the final paint coat. ### Drying Times Drying time varies with the depth of the repair: - **Repairs under 2mm deep:** Allow **2–3 hours** before sanding or painting - **Repairs up to 6mm deep:** Allow **24 hours** before sanding or painting These times are based on approximately 25°C and moderate humidity. In cooler temperatures or high humidity, drying will take longer. Do not apply the product below 5°C, as the curing process will be inhibited. For repairs deeper than 6mm, build up the product in multiple layers, allowing each layer to dry fully before applying the next. Trying to fill a very deep void in a single application increases the risk of shrinkage and uneven drying. --- ## Exterior Use Considerations No More Cracks Large Cracks & Holes works on exterior surfaces, but exterior applications require a few additional steps. **Prime the surface first.** On exterior surfaces, priming before application strengthens adhesion and helps the repair hold up against temperature variation and moisture cycling. **Protect from rain until painted.** Keep the repair dry until it has been painted over. The paint coat provides the primary weather barrier — an unpainted filler repair on an exterior surface is exposed to water ingress, which can soften or dislodge it. **Avoid exterior timber with high water absorption.** This product is not recommended for exterior timber prone to excessive water absorption. On such surfaces, repeated wetting and drying cycles cause the timber to expand and contract beyond what the filler can tolerate, leading to repair breakdown. --- ## Limitations and When to Use a Different Product No More Cracks Large Cracks & Holes has three clearly defined limitations worth knowing before you start. ### Temperature Restriction Do not apply below **5°C**. At low temperatures, the water-based acrylic formula will not cure correctly. The product may appear to dry on the surface while remaining soft underneath — or it may freeze before curing — resulting in a repair that won't hold. In cooler climates or during winter, always check ambient and surface temperatures before application. ### Not Suitable for Surfaces Subject to Movement This product is not designed for cracks or joints where ongoing movement occurs — expansion joints, junctions between two different building materials, or areas subject to structural flex. For these applications, a flexible sealant such as [Selleys No More Gaps®](https://www.selleys.com.au) is the right choice. Applying a rigid filler to a moving joint will result in the repair cracking again as the surfaces shift. ### Exterior Timber with Excessive Water Absorption As noted in the exterior use section, highly absorbent exterior timber is outside this product's recommended scope. The repeated moisture cycling in such timber creates stress that exceeds what this filler is formulated to handle. --- ## Storage and Handling Correct storage keeps No More Cracks Large Cracks & Holes ready to use whenever you need it: - **Keep the lid sealed tightly** after each use to prevent the product from drying out in the container. - **Store in a cool, dry location** away from direct sunlight and heat sources. - **Do not allow the product to freeze.** Freezing permanently damages the acrylic emulsion, making the product unusable. If it has been exposed to freezing temperatures, don't use it — the repair quality will be compromised. If a skin forms on the surface of the product in the tub after extended storage, remove it carefully before use. The product underneath remains workable if it has been stored correctly and kept away from temperature extremes. --- ## Safety Considerations No More Cracks Large Cracks & Holes has a comparatively low hazard profile as a water-based product, but standard precautions apply: - **Ventilation:** The water-based formula produces lower VOC emissions than solvent-based alternatives, but work in a well-ventilated space when applying any surface coating or filler. - **Skin and eye contact:** Avoid prolonged skin contact and keep the product away from eyes. If contact occurs, rinse thoroughly with water. - **Keep out of reach of children:** Store securely away from children, as with all building and repair products. - **Disposal:** Do not dispose of excess product down drains or into waterways. Allow small amounts to dry fully before disposing with general waste, or contact your local council for guidance on larger quantities. --- ## Tips for a Clean, Professional Finish - **Dampen highly absorbent surfaces slightly before application.** On bare plaster or old masonry, a light misting of water before application slows the initial absorption of moisture from the filler, improving adhesion and reducing the risk of the repair drying too quickly at the edges. - **Use a damp finger or brush to feather edges.** Around curved surfaces or irregular edges where getting a perfectly flush finish with the blade is tricky, a damp finger or soft brush smooths and feathers the filler before it sets. - **Sand lightly between coats on deep repairs.** When building up a deep repair in multiple layers, a light sand between coats helps the next layer bond properly and produces a flatter, cleaner final surface. - **Prime before painting repaired areas.** Even on interior surfaces, priming the repair before the final paint coat improves colour uniformity and prevents the repaired area from showing through as a dull or differently textured patch — a common issue known as "flashing." - **Inspect the repair after the first paint coat.** Minor imperfections often become visible once paint is applied. Check after the first coat dries, address any remaining low spots with a small amount of filler, allow to dry, sand lightly, and apply the second coat. --- ## References - [Selleys No More Cracks Large Cracks & Holes – Official Product Page, Selleys Australia](https://www.selleys.com.au/fillers/no-more-cracks-large-cracks-holes/) - [DuluxGroup Pty Ltd – Manufacturer Information](https://www.duluxgroup.com.au) - Based on manufacturer specifications and Technical Data Sheet provided (Selleys No More Cracks™ Large Cracks & Holes, Version 2, DuluxGroup Pty Ltd) ##
