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. Manufactured by Selleys, a division of DuluxGroup Australia Pty Ltd, it works for both DIY users and trade professionals who need a reliable repair solution with no preparation involved.

The product's main advantage is its ready-to-use format. Powder-based fillers need mixing with water. Two-part compounds demand precise ratios. This paste comes pre-prepared and goes straight from the container to the wall — which removes one of the most common causes of a poor repair (inconsistent mixing) and cuts the time between opening the product and getting to work.

The filler is a tan-coloured paste with a mild characteristic odour. It is classified as a hazardous substance under Australian safety standards (Skin Sensitisation Category 1, Signal Word: Warning), but is not classified as Dangerous Goods for transport purposes. That distinction matters practically: the product ships and stores without the regulatory requirements that apply to Dangerous Goods, while still requiring appropriate handling precautions during use.

Available Sizes

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

• 350g — suited to small touch-up jobs, single rooms, or occasional repairs
• 520g — a mid-range option for moderate repair tasks
• 750g — the right choice for larger surface areas or multiple repair locations
• 1.6kg — the largest size, suited to trade use or extensive repair projects

Picking the right size reduces waste and keeps the job moving without interruption. For a single wall with a few hairline cracks or minor dents, the 350g container is enough. For full room preparation before repainting, the 750g or 1.6kg sizes offer better value.

Key Features and What They Mean in Practice

Ready-to-use formula

The RTU designation means no mixing, no water addition, and no activation before application. Open the container and apply. This matters especially for intermittent use: the product stays ready between sessions in a way that mixed compounds don't, provided the container is properly resealed.

For DIY users, this removes a real technical barrier. Getting the right consistency from a mixed filler takes experience — an incorrect mix ratio produces a filler that shrinks excessively, cracks after drying, or loses adhesion. The pre-formulated paste takes that variable out entirely, giving first-time users the same starting point as seasoned professionals.

Paste consistency

The paste format delivers workability that powder or liquid alternatives can't match. Load it onto a filling knife or flexible scraper, press it into the crack or dent with controlled pressure, work it into the recess, and smooth the surface flush. The tan colouring gives a clear visual indicator of coverage and fill depth during application, so you can see exactly where you've been and what still needs attention.

Product classification: hazardous but not Dangerous Goods

Under the Australian Dangerous Goods framework, products are classified based on transport and storage risk — flammability, reactivity, systemic toxicity, and similar hazards. Selleys No More Cracks RTU Cracks & Dents doesn't meet the threshold for Dangerous Goods classification, so it transports and stores without specialist requirements.

It is, however, classified as hazardous under workplace health and safety legislation, specifically for Skin Sensitisation Category 1. Repeated or prolonged skin contact can cause an allergic skin reaction in susceptible individuals. The Signal Word "Warning" indicates a moderate level of hazard — serious enough to require precautions, but not at the highest level of concern. This classification applies to the product as used, not just in industrial quantities.

Application Guide

Surface preparation

Before applying filler, the surface must be clean, dry, and free of loose material. Remove any flaking paint, dust, or debris within and around the crack or dent. A stiff brush or vacuum clears loose particles from inside a crack. Damp or grease-contaminated surfaces prevent proper adhesion, so preparation is where a professional result actually begins.

For very fine hairline cracks, slightly widen the crack with a scraper or filling knife before application. This creates a small channel that allows the paste to seat properly, rather than sitting on the surface over a gap too narrow to fill.

Applying the filler

Load a small amount of paste onto a flexible filling knife or scraper. Press the paste firmly into the crack or dent, working at an angle to push material into the recess. Once the void is filled, draw the knife flat across the surface to remove excess paste and leave the repair as flush as possible with the surrounding surface.

For deeper repairs, apply the filler in multiple thin layers rather than a single thick application. Thin applications take longer to dry and are more prone to surface cracking or shrinkage as moisture evaporates. Allow each layer to dry fully before applying the next — patience here is what produces a clean visible result at the end.

Drying and finishing

After application, the filler needs drying time before sanding or painting. Drying time varies depending on the depth of the repair, ambient temperature, and humidity. Cooler or more humid conditions extend drying time. As the paste dries, it lightens in colour — a reliable visual cue that the repair is ready for the next step.

Once dry, sand the repair smooth using fine-grit sandpaper to blend the filled area with the surrounding surface. Wipe away dust before applying primer or paint. Always prime the repaired area before painting — bare filler absorbs paint unevenly and produces a visible patch even after topcoating. Priming locks in a consistent surface and sets up a finish that actually holds.

Safety Considerations and Required PPE

Given the product's hazardous classification for skin sensitisation, wear appropriate personal protective equipment during use. The manufacturer specifies:

• Safety shoes — to protect feet from spills or dropped containers
• Overalls — to protect skin and clothing from contact with the paste
• Nitrile rubber gloves — specifically nitrile, not latex or vinyl, for a strong barrier against the sensitising components
• Safety glasses — to protect eyes from splashes, particularly during application or sanding dried filler

Nitrile gloves are specified because nitrile rubber delivers superior chemical resistance compared to latex or vinyl for this product type. Latex gloves may not provide adequate protection and introduce an additional sensitisation risk for users with latex sensitivity.

Skin sensitisation works cumulatively: the first exposure may produce no reaction, but repeated contact over time can cause the immune system to recognise the sensitising agent, triggering an allergic response on subsequent exposures. PPE matters even for occasional users — the risk builds from cumulative exposure, not just from a single heavy-use session.

If skin contact occurs, wash the affected area thoroughly with soap and water. If an allergic reaction develops — redness, itching, or rash — seek medical advice.

Ventilation

The product has only a mild characteristic odour and is not classified as a volatile hazardous substance. Working in a well-ventilated space is still good practice, and especially important when sanding dried filler, which generates fine dust that shouldn't be inhaled. Use a dust mask during sanding.

Storage and Handling

Store the product in a cool, dry location away from direct sunlight and extreme heat. Reseal the container tightly after each use to keep the paste in working condition. If the surface of the paste begins to dry between uses, remove the dried skin before applying fresh paste — this stops hardened lumps from working their way into the repair.

The product is not classified as Dangerous Goods for transport, so no specialist storage conditions apply from a regulatory standpoint. Standard practice still applies: keep the product away from children and food, and store the container upright.

Shelf life is directly affected by storage conditions. Heat accelerates drying inside the container. Contamination from water or other substances affects product performance. Use a clean knife every time you take paste from the container — a simple habit that protects the product and keeps every repair performing as it should.

Troubleshooting Common Issues

Repair is cracking after drying: The layer was applied too thick in a single pass. The outer surface dries faster than the interior, and as the inner material continues to shrink, it pulls the surface apart. Apply thinner layers and allow each to dry fully before adding the next.

Filler is not adhering to the surface: The surface was damp, dusty, or contaminated at the time of application. Remove the filler, prepare the surface correctly, and reapply. Proper preparation is what separates a repair that lasts from one that doesn't.

Visible patch after painting: The repaired area was not primed before painting. Bare filler absorbs paint differently from the surrounding surface. Sand the area smooth, apply a coat of primer, allow it to dry fully, then repaint.

Paste has dried out in the container: The container was not resealed properly between uses. If only the surface has dried, remove the dried skin — the paste beneath may still be usable. If the paste has dried throughout, the product is no longer viable.

Repair is taking a very long time to dry: High ambient humidity or low temperature is slowing the drying process. Improve ventilation, raise room temperature where possible, and allow additional drying time before sanding or painting. Rushing this step costs more time in the end.
