Product overview

Selleys No More Cracks RTU Plaster Filler comes out of the container ready to work. This pre-mixed interior filler handles cracks, holes, and surface imperfections in plaster walls and ceilings. Manufactured by Selleys, a division of DuluxGroup Australia Pty Ltd, it's a go-to product for DIY home repair and professional trade work across Australia and New Zealand.

The RTU formulation is the practical point of difference here. It's a pre-mixed white paste with a mild characteristic odour — open the container and start applying. No preparation, no guesswork, no delays. That's a meaningful contrast to powder-based fillers, which require you to measure water, mix to the right consistency, and use the batch before it sets. Get the ratio wrong and you end up with filler that's too runny, too stiff, or prone to cracking after it dries — a job you'll need to do twice.

The 100 g format reviewed here suits small repair jobs well: hairline cracks, minor plaster chips, spot repairs before repainting.

What "ready to use" actually means

The RTU label on this product carries real weight. Many plaster fillers come in powder form, requiring you to measure water, mix to the correct consistency, and use the batch before it sets. Get the ratio wrong and you end up with filler that's too runny, too stiff, shrinks excessively, or cracks after drying — a job you'll need to do twice.

Selleys No More Cracks removes that variable entirely. The paste is formulated to the correct working consistency at the factory. Open the container, apply directly to the surface, and get on with the job. No mixing stage, no waste from over-preparation, no risk of incorrect consistency.

For homeowners tackling occasional wall repairs, the path to a clean result is straightforward — success the first time.

Intended applications

This product sits in the Home & Garden > Wall Repair & Fillers category and is formulated specifically for interior plaster surfaces. Using it where it's designed to perform is how you get the right result.

Suitable surfaces include:

Plaster walls and ceilings (the primary intended substrate)
Interior plaster around cornices, architraves, and wall joins

Not intended for:

Exterior surfaces — moisture and temperature variation require a different product formulation
Non-plaster substrates such as timber, masonry, or fibre cement without confirming suitability
Structural repairs or filling large voids

This product is built for cosmetic and surface-level repairs — restoring a smooth, paintable finish to damaged plaster. It's not a structural solution, and using the right product for the job is how you get clean, lasting results.

How to apply Selleys No More Cracks

Apply this filler correctly and you get a clean, durable finish that takes paint without a trace. The process below reflects sound practice for a ready-mixed plaster filler.

Surface preparation

Start with a clean, dry surface free of loose material. For cracks, use a scraper or filling knife to remove any flaking plaster around the edges, then dust the area clean. On particularly porous or dusty surfaces, a light mist of water or a diluted PVA primer improves adhesion — though for minor repairs to sound plaster, this step is often unnecessary.

Application

Open the container and apply the paste directly to the repair area using a filling knife or flexible scraper. For hairline cracks, press the filler firmly into the crack, working it in with the blade. For slightly larger surface holes, build the filler up in thin layers rather than loading it all in at once — thick single applications are more prone to shrinkage and surface cracking as the product dries.

Draw the blade across the surface at a shallow angle, leaving the filler sitting slightly proud of the surrounding wall. This accounts for minor shrinkage during drying and sets you up for a flush finish when sanding.

Drying and finishing

Allow the filler to dry fully before sanding. Drying time depends on ambient temperature, humidity, and the depth of the repair. In typical indoor conditions, thin applications dry within a few hours; deeper fills may need overnight drying. Watch for the colour change — a fully dried application turns uniformly white and feels firm to the touch.

Once dry, sand the repair flush with the surrounding surface using fine-grit sandpaper. 120–180 grit is the right choice for most plaster finishing work. Wipe away dust before priming or painting.

Priming before painting

Filled areas absorb paint differently from the surrounding painted surface. A coat of primer — or a diluted first coat of paint — over the repair before the final topcoat ensures consistent sheen and colour absorption. This one extra step prevents the repair from showing as a dull patch through the finished paint.

Safety information and PPE requirements

Selleys No More Cracks RTU Plaster Filler carries a Hazardous, NON-Dangerous Goods classification. Understanding what this means in practice keeps you working safely.

Hazardous vs. Dangerous Goods — the distinction

These two classifications operate under different regulatory frameworks and are often confused.

Dangerous Goods is a transport classification. A product classified as Dangerous Goods requires special handling, labelling, and documentation during road, rail, sea, or air transport. Selleys No More Cracks is not classified as Dangerous Goods under Australian or New Zealand transport regulations. It moves through normal retail channels without restriction.

Hazardous is a workplace health and safety classification under the Safe Work Australia framework, aligned with the Globally Harmonised System of Classification and Labelling of Chemicals (GHS). A product can carry a hazardous classification under WHS/OHS regulations while remaining non-dangerous for transport purposes. This classification requires a Safety Data Sheet (SDS) and appropriate personal protective equipment (PPE) during use.

Required PPE

The Safety Data Sheet (SDS) for this product specifies the following personal protective equipment:

PPE item	When required	Purpose
Safety shoes	During use	Protection from spills or dropped containers
Overalls	During use	Skin and clothing protection
Nitrile rubber gloves	Intermittent contact	Hand protection from prolonged skin contact
Safety glasses	During use	Eye protection from splashes

For a typical household repair — applying a small amount of filler to a wall crack — the scale of the task will guide how much of this PPE you put on. The SDS is the manufacturer's formal safety guidance, and every user should assess their own exposure level accordingly. At minimum, avoid prolonged skin contact (particularly for those with sensitive skin) and keep the product away from your eyes. Professionals using the product regularly should apply the full PPE requirements.

First aid considerations

As a water-based paste, the primary exposure risks are skin and eye contact. Eye contact requires thorough flushing with water — seek medical advice if irritation continues. For skin contact, wash with soap and water. This product carries no inhalation hazard classification under normal use conditions, though working in a well-ventilated space is sound practice with any coating or filler product.

Storage and product care

Store this product correctly and it stays ready whenever the next job comes up. As a water-based paste, it dries out if the container isn't properly sealed after use — and a dried-out filler is useless.

Key storage practices:

Reseal the container tightly straight after use
Store in a cool, dry location away from direct sunlight and heat sources
Keep the product away from freezing temperatures — freezing permanently alters the paste consistency
Keep the rim and lid clean to maintain an airtight seal; dried filler around the rim stops the lid from closing properly

Stored correctly, an opened container of ready-mixed filler stays usable for an extended period. A thin skin may form on the surface if the paste is exposed to air — remove it and the product underneath performs as it should.

Practical tips for best results

These points address the common issues that come up with ready-mixed plaster fillers.

Work in thin layers for deeper repairs. For holes or cracks deeper than approximately 5 mm, apply the filler in two or more passes, letting each layer dry fully before the next goes on. A single thick application allows moisture to escape unevenly during drying, which leads to cracking and shrinkage.

Sand with control, not force. It's easy to sand through a thin filler application and straight back into the surrounding plaster. Use light, even pressure and check your progress frequently. A sanding block — rather than bare sandpaper — keeps the surface flat and consistent.

Match the repair to the texture. A perfectly smooth filler repair on a textured wall will stand out under paint. Once the filler is dry and sanded, check whether a light texture application is needed to blend the repair with the surrounding surface before painting.

Confirm drying before painting. Painting over filler that hasn't fully dried is one of the most common causes of paint problems over repairs. The filler must be uniformly white and hard before any paint goes on.

Store the container upright. Laying it on its side lets the paste migrate toward the lid, making it harder to open and increasing the risk of air exposure.
