Product Overview

Selleys No More Cracks RTU Cracks & Dents is a ready-to-use paste filler for repairing small cracks and dents in interior surfaces. Made by Selleys, a division of DuluxGroup Australia Pty Ltd, it's aimed at tradespeople and DIYers who want a reliable, no-preparation repair product for everyday surface damage.

The RTU formulation is the main practical advantage here. Powder-based fillers need water. Two-part compounds require precise ratios. This paste comes pre-mixed and goes straight from the container to the surface — which removes inconsistent mixing as a source of error and cuts preparation time entirely.

The product is tan coloured with a mild characteristic odour. It's classified as hazardous under Australian safety standards (Skin Sensitisation Category 1, Signal Word: Warning), but not classified as Dangerous Goods for transport purposes. That distinction matters in practice: the product moves and stores without the special handling requirements of Dangerous Goods, but it does require appropriate personal protective equipment (PPE) during use.

Available Sizes

Selleys No More Cracks RTU Cracks & Dents comes in four sizes:

350g — suited to minor spot repairs or small projects
520g — a mid-range option for moderate repair work
750g — appropriate for larger surface areas or multiple repairs
1.6kg — the largest available size, practical for trade use or extensive repair jobs

Matching the size to the scope of the project matters more than it might seem. Once opened, the paste is exposed to air, which affects workability over time. Buy the right amount for the job and the product stays in good condition from start to finish.

Key Features and What They Mean

Ready-to-use formula

No mixing, no water, no preparation before application. Open the container and get started. This is especially useful on small, isolated repairs where preparing a batch of mixed filler would waste both time and product.

Paste consistency

The paste form gives a workable consistency that applies cleanly with a filling knife or putty knife, presses into cracks and dents, and shapes before it sets. Paste fillers bond reliably to the substrate and feather at the edges to blend with the surrounding surface, which is what produces a clean, invisible finish.

Tan colouring

The tan colour has a practical purpose: it creates visual contrast against most interior wall surfaces, making it easy to see where filler has been applied and spot any areas needing additional coverage. Once dried and sanded, the surface gets primed and painted, so the original filler colour has no effect on the final result.

Application Guidance

Surface preparation

Before applying the filler, the surface needs to be clean, dry, and free of loose material. Remove any flaking paint, dust, or debris within and around the crack or dent. For cracks, slightly widen and deepen the opening with a scraper or filling knife to give the filler something to grip. This step gets skipped often — but it's what separates a lasting repair from one that needs redoing.

Applying the filler

Apply the paste directly from the container using a filling knife or flexible spatula. Press it firmly into the crack or dent, working it in to eliminate air pockets. Overfill the repair slightly — the filler shrinks a little as it dries, and a slight overfill means the finished surface sands back flush.

For deeper repairs, apply the filler in layers and let each one dry before applying the next. Filling a deep void in a single application causes surface cracking and poor adhesion because the outer layer dries faster than the interior. Taking the time to layer it properly makes a real difference to the end result.

Drying and finishing

Let the filler dry fully before sanding. Drying time varies depending on application depth, ambient temperature, and humidity. Once dry, sand the repaired area smooth using fine-grit sandpaper, feathering the edges to blend with the surrounding surface. Prime before painting to ensure even paint absorption and a consistent finish.

Safety Considerations and PPE Requirements

This product is classified as hazardous under Australian safety regulations, specifically under Skin Sensitisation Category 1 with a Signal Word of Warning. That classification means it has the potential to cause an allergic skin reaction on contact. Appropriate precautions are required during every use.

Required personal protective equipment

The Safety Data Sheet (SDS) for this product specifies the following PPE:

Safety shoes — to protect against spills or dropped containers
Overalls — to prevent skin contact with the paste during application
Nitrile rubber gloves — nitrile is specified because it resists the sensitising agents in the formulation; standard latex or vinyl gloves don't offer equivalent protection
Safety glasses — to protect eyes from splashes or airborne particles during sanding

Hazardous vs. Dangerous Goods: an important distinction

These are separate regulatory classifications under Australian law. Hazardous refers to the health or physical risks a product poses during use, which requires safety precautions and PPE. Dangerous Goods refers to transport classification under the Australian Dangerous Goods Code, which governs how products are stored, handled, and transported.

Selleys No More Cracks RTU Cracks & Dents is hazardous but not classified as Dangerous Goods. It can be purchased, transported, and stored without the restrictions that apply to Dangerous Goods — but it must be used with the PPE outlined above, every time.

First aid considerations

Given the skin sensitisation classification, wash any skin contact area thoroughly with soap and water immediately. If an allergic reaction develops or eye contact occurs, seek medical advice without delay. Full first aid guidance is in the product's Safety Data Sheet, which should be read before first use.

Storage and Handling

Store in a cool, dry location away from direct sunlight and heat sources. Seal the container tightly after every use to keep the paste workable and prevent a skin forming on the surface. If a skin does form on the top layer, remove it to access the usable product beneath, provided the bulk of the paste is still workable.

Keep out of reach of children. The hazardous classification makes secure storage essential.

Practical Tips

Work in sections. On larger areas with multiple cracks or dents, work systematically rather than applying filler to everything at once. This keeps drying times manageable and ensures each repair gets proper attention.
Clean tools immediately. Filler that dries on filling knives or spatulas is stubborn to remove and contaminates later applications. Rinse with water straight after use, before the paste sets.
Sand between coats. When building up layers on a deep repair, lightly sand each dried layer before applying the next. This improves adhesion between layers and produces a more solid result.
Always prime before painting. Skipping primer is the most common mistake after surface repair. Unprimed filler absorbs paint unevenly and produces a patchy finish that draws attention to the repair rather than hiding it.
Read the SDS before first use. Given the hazardous classification, this is worth doing — particularly for anyone with sensitive skin or known skin conditions.
