Can this product be used on exterior surfaces? → Yes, with mandatory priming before application and paint protection from rain until fully sealed with a paint coat --- ## Product Overview Selleys No More Cracks™ Large Cracks & Holes does what it says. This ready-to-use acrylic filler is built for repairing significant surface damage: cracks, holes, and voids across a wide range of interior and exterior surfaces. Manufactured by DuluxGroup Pty Ltd under the Selleys name, it handles damage that standard fine-crack fillers simply can't touch, while staying straightforward enough for any confident DIYer to pick up and use successfully. This is a water-based acrylic paste. It applies smoothly, cleans up with water, and bonds to surfaces through a combination of mechanical adhesion and acrylic polymer chemistry. It works on plaster, mortar, concrete, timber, and primed metal, covering the vast majority of surfaces found in residential and light commercial settings. Knowing what this product is, how it works, and where its limits are is the foundation of getting professional results every time. --- ## Key Features and What They Mean ### Adhesion across multiple surfaces What defines No More Cracks Large Cracks & Holes is its ability to bond reliably across dissimilar surface types. Plaster, concrete, mortar, timber, and primed metal each carry different surface energies and textures. This single formulation handles all of them, which means fewer products to buy, less guesswork about compatibility, and confident results even when a repair spans more than one material, like a crack running from a plaster wall into a concrete sill. Adhesion in acrylic fillers works through polymer chains physically interlocking with the porous surface as the water carrier evaporates during drying. Surface preparation determines bond quality directly, which is why a clean, dry, and sound surface is the starting point for every successful repair. ### Minimal shrinkage Shrinkage is the enemy of any filler repair. As water-based fillers dry, water evaporates and the filler mass reduces in volume. Excessive shrinkage causes the repaired area to sink below the surrounding surface, forcing multiple fill-and-sand cycles, and in worse cases, cracking within the repair itself. No More Cracks Large Cracks & Holes is formulated to keep shrinkage low. That matters most given this product handles repairs up to 6mm deep. At that depth, a high-shrinkage filler forces multiple applications as a matter of course. With this formulation, many repairs within the product's rated depth come out right in a single application, saving real time on any job. ### Water-based acrylic formula The water-based acrylic chemistry delivers several practical advantages. The product is low in volatile organic compounds (VOCs), making it safe to use in enclosed interior spaces without heavy ventilation. Tools and hands clean up with water, no solvents required. And once fully cured, the acrylic binder provides a degree of flexibility that purely mineral-based fillers can't match, helping the repair resist minor movement and thermal expansion cycles so the result holds up long after the job is done. --- ## Technical Specifications Understanding the specific performance parameters of this product lets you plan repairs accurately and walk away with results that last. ### Dry times Dry time varies directly with repair depth: - **Repairs under 2mm:** Dry in approximately 2–3 hours under normal conditions - **Repairs up to 6mm:** Require approximately 24 hours to dry fully These figures apply at or above 5°C with reasonable air circulation. Higher humidity, lower temperatures, or restricted airflow will extend dry times. The 24-hour figure for deeper repairs is a minimum. In cool or humid conditions, allow additional time before sanding or painting. The practical takeaway: plan deep repairs as a two-stage process. Fill on day one, sand and finish on day two. Sanding or painting a deep repair before it has fully dried damages the repair surface and risks adhesion issues in the subsequent paint coat. ### Maximum repair depth: 6mm The 6mm maximum depth rating is a defined technical limit. Acrylic fillers rely on water evaporation to cure. Beyond a certain depth, the outer surface skins over before the interior has dried, trapping moisture and leading to poor adhesion, extended cure times, and potential cracking as the interior eventually dries and contracts. For holes or voids deeper than 6mm, build up the repair in layers. Allow each layer to dry fully before applying the next. This approach maintains the integrity of each individual application while progressively filling the void to a professional standard. ### Available formats The product comes in four formats: - **230g tub** - **450g tub** - **1kg tub** - **230g tottle** (a squeezable tube for controlled dispensing) Tub formats suit larger repairs or multiple repairs in a single session, with a filling blade as the primary application tool. The tottle delivers more precise dispensing for smaller repairs or narrow cracks where you don't want to overload the surrounding surface. Choosing the right format gives you better control and a cleaner result. --- ## Suitable Surfaces and Applications ### Interior applications On interior surfaces, No More Cracks Large Cracks & Holes works across the full range of common wall and ceiling substrates. Plaster and plasterboard repairs, nail holes, impact damage, settlement cracks, are the most common use case, and this product handles all of them. It works equally well on concrete and masonry surfaces inside the home: basement walls, rendered surfaces, and brick mortar repairs all respond well to this formulation. For interior timber, the product bonds effectively to primed or painted surfaces, making it the right choice for repairing damage to architraves, skirting boards, and door frames. Prime the surface before application on timber to get the strongest possible bond. ### Exterior applications This product is rated for exterior use, extending its reach to outdoor walls, rendered facades, concrete paths and structures, and exterior masonry. Exterior use carries specific requirements that must be observed for the product to perform as specified: 1. **Prime the surface first.** Exterior surfaces vary more in porosity and condition than interior ones. Priming before application ensures a consistent, sealed substrate that supports strong adhesion. 2. **Protect from rain until painted over.** The acrylic filler is not waterproof until sealed with a paint coat. Rain on a newly applied or recently dried repair can damage the filler before it is fully protected. These are not optional precautions. They are the conditions under which this product delivers its full, specified performance on exterior surfaces. ### Where this product is not suitable No More Cracks Large Cracks & Holes is not the right choice in the following situations: - **Below 5°C:** At temperatures below 5°C, the acrylic polymer cannot cure correctly. Application in cold conditions results in poor adhesion, extended or incomplete drying, and a repair that won't hold. - **Exterior timber with excessive water absorption:** Timber that is frequently wet, unprimed, or highly porous will not provide a stable substrate. Repeated wetting and drying cycles cause the timber to move in ways that exceed the filler's flexibility limits. - **Surfaces subject to movement:** Where a crack or joint is subject to ongoing structural movement, expansion joints, control joints, or movement cracks, a rigid filler is not the right solution. Selleys recommends using Selleys No More Gaps® in these situations. A flexible sealant accommodates movement without cracking, delivering the lasting result the job demands. Using any filler in conditions it is not designed for won't produce a suboptimal result. It will produce a repair that needs to be stripped out and redone. Use the right product and you get it right the first time. --- ## Application Method ### Surface preparation Surface preparation is the single most important step in achieving a repair that lasts and looks right. Before applying filler: 1. Remove all loose material from the crack or hole. Use a scraper, wire brush, or vacuum to clear dust, debris, and any friable material. 2. Ensure the surface is dry. Moisture in the substrate interferes with adhesion and extends dry times. 3. For porous or dusty surfaces, and for all exterior applications, apply a suitable primer and allow it to dry fully before applying filler. Get the preparation right, and the rest of the job follows naturally. ### Applying the filler 1. Using a filling blade or scraper, press the filler firmly into the crack or hole. Firm pressure ensures the filler fully contacts the substrate and eliminates air pockets that would weaken the repair. 2. Overfill slightly, then scrape off the excess to leave the repair flush with or very slightly proud of the surrounding surface. This accounts for minor shrinkage during drying. 3. For repairs deeper than 6mm, apply in layers. Allow each layer to dry fully, up to 24 hours for deep fills, before applying the next. 4. For the tottle format, dispense directly into the crack and then work with a blade to press in and level off cleanly. ### Finishing Once the filler has dried completely, sand the repair smooth using fine sandpaper. The goal is a surface that sits flush with the surrounding material, with no ridges or edges that would show through a paint coat. After sanding, dust off the repair area before priming and painting. --- ## Storage and Care Store the product in a cool, dry location away from direct sunlight and heat sources. Seal the lid tightly after each use to prevent the filler from drying out in the container. Do not allow the product to freeze. Freezing damages the acrylic emulsion and renders the product unusable. If a skin forms on the surface of the filler in the tub between uses, remove and discard the skin before using the remaining product. The filler beneath an intact skin is generally still in good condition, provided it has not dried out or been contaminated. --- ## Safety Considerations As a water-based acrylic product, No More Cracks Large Cracks & Holes presents a low hazard profile compared to solvent-based fillers. Standard precautions apply: - Avoid prolonged skin contact. Wash hands thoroughly after use. - In enclosed spaces, ensure adequate ventilation during application and drying, particularly for large repair areas. - Keep out of reach of children. - Refer to the product's Safety Data Sheet (SDS), available from Selleys or DuluxGroup, for full hazard and first aid information. --- ## Expert Tips - **Dampen highly porous surfaces** lightly before applying filler on interior jobs where priming is not being done. This slows the rate at which the substrate draws moisture from the filler, giving better adhesion and a smoother finish. - **Use the tottle format for cracks** where precision matters. The controlled dispensing reduces waste and makes it easy to fill a narrow crack without overloading the surrounding surface. - **Respect the dry time on deep repairs.** A repair that feels dry on the surface after a few hours may still carry significant moisture in its core. Sanding too early creates a rough, pitted surface and can pull material out of the repair. - **Sand between coats** on multi-layer repairs to ensure strong mechanical adhesion between layers and a seamless final result. - **Prime before painting**, even on interior repairs. A direct paint coat over raw filler can result in uneven sheen, called flashing, where the filler absorbs paint differently from the surrounding surface. Priming first guarantees a consistent finish across the entire wall. --- ## References - [Selleys No More Cracks Large Cracks & Holes – Product Page](https://www.selleys.com.au/fillers/no-more-cracks-large-cracks-holes/) - [Selleys No More Cracks Large Cracks & Holes – Safety Data Sheet (DuluxGroup)](https://www.selleys.com.au/media/documents/sds/) - [DuluxGroup Pty Ltd – Manufacturer Information](https://www.duluxgroup.com.au) *Note: Specific SDS and Technical Data Sheet URLs should be verified directly on the Selleys website, as document versioning may update URLs.
