Product Overview

Selleys No More Cracks RTU Cracks & Dents is a ready-to-use repair paste for interior walls and ceilings, made by Selleys, a division of DuluxGroup Australia Pty Ltd. The whole point of this product is that there's nothing to figure out before you start. No mixing, no measuring, no prep work beyond opening the container.

It comes in four sizes: 350g, 520g, 750g, and 1.6kg. Picking the right size for the job means you won't run short halfway through a repair or end up with a half-used tub you don't need.

The filler is a tan-coloured paste with a mild characteristic odour. That paste consistency matters more than it might seem. On vertical surfaces, a thinner compound will slide or sag before it sets. This one stays put.

Key Features and What They Mean in Practice

Ready-to-use formula

RTU means Ready-to-Use, and that's exactly what it is. The filler comes pre-mixed to the right consistency — no water, no hardener, nothing extra. For DIYers, this removes one of the most common failure points in surface repair: getting the mixing ratio wrong, which affects how a filler sets, shrinks, and bonds. With Selleys No More Cracks RTU, that's already been sorted for you.

Paste form factor

A paste-form filler holds its position once applied. It stays in the crack or dent while it cures rather than spreading or settling. On horizontal surfaces, it stays where you put it. On vertical walls, it doesn't slip or sag. That's not a minor convenience — it's the difference between a repair that works and one that needs to be done again.

Tan colouring

The tan colour gives you a clear visual reference during application. Against most white or off-white wall surfaces, the contrast makes it easy to see where filler has been placed and where gaps still need attention. Once sanded and painted, the colour disappears completely under the topcoat.

Hazard Classification and What It Means for Users

Selleys No More Cracks RTU Cracks & Dents is classified as a hazardous product under Australian Work Health and Safety (WHS) regulations. Understanding what that classification actually covers is worth a moment before you start.

Skin Sensitisation Category 1

This product carries a Skin Sensitisation Category 1 classification with the signal word Warning. Skin sensitisation means repeated or prolonged skin contact may cause an allergic reaction in some people. The key thing to understand is that sensitisation builds up over time — once someone becomes sensitised to a substance, even minor future exposure can trigger a reaction. That's why skin contact should be avoided from the very first use, not only after symptoms appear.

This classification doesn't mean the product is dangerous under normal handling. It means the right protective equipment needs to be worn every time.

Transport classification

Selleys No More Cracks RTU Cracks & Dents is not classified as Dangerous Goods for transport. That's a meaningful distinction. You can buy it from a retail store, carry it home in your car, and store it without the requirements that apply to Dangerous Goods. The hazard relates to direct skin contact during use, not to storage or transit under normal conditions.

Required Personal Protective Equipment (PPE)

Given the Skin Sensitisation Category 1 classification, the following PPE is required every time you use this product:

  • Safety shoes — protection against accidental spills or dropped containers
  • Overalls — full coverage along the arms and body during application, preventing incidental skin contact
  • Nitrile rubber gloves — nitrile is specified because it provides effective resistance to the sensitising agents in this product. Latex gloves are not an equivalent substitute
  • Safety glasses — essential during scraping and sanding, when dried particles can become airborne

Each item addresses a specific exposure pathway. Gloves cover the hands, which are the most likely contact point during application. Overalls protect the forearms and torso against incidental contact. Safety glasses matter most during the sanding phase, where airborne particles are a real consideration.

PPE requirements apply to all users, including first-timers. The point is to prevent sensitisation from developing, not to manage it after the fact.

Application Guidance

Surface preparation

Start with a clean, dry surface free of loose material. Any flaking paint, dust, or debris inside the crack or dent needs to come out before you apply the filler — these will prevent proper bonding and undermine the repair. A stiff brush or vacuum clears the area quickly.

Applying the filler

Apply the paste directly from the container using a filling knife or flexible scraper. Press it firmly into the crack or dent, slightly overfilling the area to account for minor shrinkage during drying. Work the filler into the full depth of the repair, not just across the surface. Applying filler as a shallow layer over a deep crack is a common cause of cracking and detachment after drying. Go deep, press firmly, and do it once.

For deeper repairs, apply in multiple thin layers and let each one dry fully before adding the next. This produces a stronger, more stable result than a single heavy application.

Drying and finishing

Let the filler dry completely before sanding. Drying time varies depending on application depth, temperature, and humidity. Watch for the visual cues: the tan colour may lighten slightly, and the surface will feel firm to the touch. Sanding before the filler is fully dry clogs sandpaper and produces an uneven finish.

Once dry, sand the repaired area smooth with fine-grit sandpaper, feathering the edges into the surrounding surface. Remove all sanding dust before applying primer or topcoat. Done correctly, the repair disappears completely under paint.

Storage and Handling

Store in a cool, dry location away from direct sunlight and extreme temperatures. After each use, seal the container lid tightly. Paste that dries out in the container can't be reconstituted — a simple step that keeps the product usable for the next job.

Keep out of reach of children. The hazard classification relates to skin sensitisation rather than ingestion toxicity, but this isn't a product for unsupervised use by or around children.

Safety Precautions Summary

  • Wear the full set of specified PPE every time: safety shoes, overalls, nitrile rubber gloves, and safety glasses
  • Avoid prolonged or repeated skin contact — sensitisation can develop over time without obvious immediate symptoms
  • Work in a well-ventilated area, particularly during sanding
  • Wash hands thoroughly after use, even when gloves have been worn throughout
  • Dispose of waste material and empty containers in accordance with local council regulations
