Product Overview and Positioning

Selleys No More Cracks RTU Plaster Filler is a ready-mixed interior filler built for repairing plaster surfaces (SDS). The "RTU" stands for Ready To Use — no mixing, no measuring, no preparation. Open the container and get straight to work. This paste-based filler is aimed at homeowners and tradespeople tackling interior wall repairs on plaster substrates (SDS).

The product comes in a 100g format (SDS), suited to small and medium repair jobs where precision matters more than volume. The formulation targets cracks, holes, and surface imperfections in plaster walls, cutting out the complexity of two-part systems or powder-based fillers that need water addition and careful mixing.

Chemistry & Composition

This filler uses a water-based formulation built around chemical components that give it reliable working properties and long-term preservation (SDS). The base matrix consists of non-hazardous ingredients that form the bulk of the product, providing filling and adhesive strength (SDS).

The formulation includes alcohols, C12-C14, ethoxylated, sulfates, sodium salts at 1-10% by weight — surfactants that control viscosity and improve workability (SDS). These surfactants let the paste spread smoothly while keeping enough body to fill voids without sagging.

For microbial preservation — essential in water-based fillers that could otherwise support bacterial or fungal growth during storage — the product uses a blend of isothiazolinone biocides at trace concentrations (SDS):

1,2-Benzisothiazol-3(2H)-one (BIT) at less than 0.05% w/w (SDS)
5-Chloro-2-methyl-4-isothiazolin-3-one (CMIT) at less than 0.05% w/w (SDS)
2-Methyl-2H-isothiazol-3-one (MIT) at less than 0.05% w/w (SDS)
2-Octyl-2H-isothiazol-3-one (OIT) at less than 0.1% w/w (SDS)

These isothiazolinone preservatives are broad-spectrum antimicrobials that work at very low concentrations, which is why they appear at sub-0.1% inclusion rates. Their presence does create the product's primary hazard profile — they are known skin sensitisers that require careful handling.

Hazard Classification & Safety Requirements

Selleys No More Cracks RTU Plaster Filler carries a Warning signal word under the GHS classification system (SDS), meeting the criteria for two hazard classifications under Safe Work Australia GHS 7 standards (SDS).

Eye Irritation — Category 2A: The filler causes serious eye irritation (H319). Contact with eyes produces reversible but significant irritation requiring immediate flushing (SDS). This hazard comes from the alkaline nature and surfactant content of the formulation.

Skin Sensitisation — Category 1: The product may cause an allergic skin reaction (H317), attributed to the isothiazolinone preservatives (SDS). Repeated skin exposure can lead to sensitisation — after which even small amounts may trigger allergic contact dermatitis. Once sensitised, a person may react to the product indefinitely.

These hazards require protective gloves, protective clothing, and eye/face protection (P280) during handling (SDS). Nitrile rubber gloves are appropriate for intermittent contact, though users should assess suitability based on glove construction and their specific working conditions (SDS).

The hazard profile also calls for clear operational controls: avoid breathing dust, fume, gas, mist, vapours or spray (P261); wash hands, face and all exposed skin thoroughly after handling (P264); and ensure contaminated work clothing is not removed from the workplace without proper handling (P272) (SDS).

The product is not classified as a Dangerous Good under the Australian Code for the Transport of Dangerous Goods by Road & Rail or New Zealand NZS5433 standards, which simplifies storage and transport logistics (SDS).

Application Methodology

As a ready-mixed filler, this product removes the preparation phase that slows down powder-based systems. Apply the paste directly to clean, dry plaster surfaces using a putty knife, filling knife, or similar spreading tool. The ready-to-use consistency is pre-adjusted to an optimal working viscosity — firm enough to stay in place, smooth enough to spread with precision.

Work in a well-ventilated area. This supports drying and keeps airborne exposure from wet material to a minimum. The substrate must be free of loose material, dust, grease, and any previous coating failures that could undermine adhesion. For deep voids, apply in multiple layers rather than one thick fill — this prevents extended drying times and shrinkage.

During application, avoid breathing any mist or spray (P261) and wash hands thoroughly after handling (P264) (SDS).

Exposure Response Protocols

The product's hazard classification requires clearly defined first aid procedures for different exposure routes (SDS).

Skin contact: If the filler contacts skin or hair, remove contaminated clothing immediately and flush affected areas with running water (SDS). Effects can be delayed, particularly in individuals developing sensitisation, so monitor for swelling, redness, blistering or irritation (SDS). Seek medical assistance if these symptoms appear (SDS). If skin irritation or rash develops, obtain medical advice or attention (P333+P313) (SDS).

Eye contact: Hold eyelids apart and flush eyes continuously with running water until advised to stop by a Poisons Information Centre (Australia 131 126, New Zealand 0800 764 766) or a doctor, or for at least 15 minutes (SDS). Remove contact lenses during rinsing if possible (P305+P351+P338) (SDS). Seek medical care if eye irritation persists after flushing (P337+P313) (SDS).

Inhalation: Move the affected person away from exposure immediately, ensuring rescuers protect themselves in the process (SDS). Remove contaminated clothing, loosen remaining garments, and allow the person to rest in a comfortable position while keeping warm (SDS). Seek medical advice if effects persist (SDS).

Ingestion: Rinse the mouth with water — do not induce vomiting (SDS). Give a conscious person a glass of water to drink, and never administer anything by mouth to an unconscious patient (SDS). If vomiting occurs naturally, provide additional water (SDS). Seek medical advice for all ingestion incidents (SDS).

For poisoning incidents, contact the Poisons Information Centre (Australia 131 126, New Zealand 0800 764 766) or a doctor, and have the product container or label available for reference (P101) (SDS).

Workplace Safety Management

Contaminated work clothing must not leave the workplace without proper decontamination (P272) (SDS). This keeps sensitisers out of home environments where family members — especially children — could be exposed to contaminated garments.

Remove contaminated clothing and wash before reuse (P362+P364) (SDS). Washing eliminates residual product that could otherwise cause cumulative sensitisation through repeated low-level contact with stored work clothing.

First aiders attending to exposure incidents must wear their own PPE: safety shoes, overalls, gloves, and safety glasses (SDS). This prevents secondary exposure during rescue and treatment, which matters given the skin sensitisation hazard.

Keep the product out of reach of children (P102) and read and follow all instructions carefully (P103) (SDS). These precautions are especially relevant in residential settings where the 100g package makes the product accessible for small home repairs.

Storage, Handling & Disposal

The ready-mixed formulation needs protection from drying and contamination during storage. Water-based fillers require frost protection — freeze-thaw cycles destroy paste structure and compromise performance. Keep the container tightly sealed between uses to prevent surface skinning and moisture loss.

During handling, wash hands before smoking, eating, drinking or using the toilet (SDS). This prevents ingestion of material from contaminated hands, an important step given the skin sensitisation hazard.

Dispose of the product in compliance with local, regional, national and international regulations (P501) (SDS). While the product is not classified as a Dangerous Good, the presence of isothiazolinone preservatives may trigger specific waste classification requirements depending on your jurisdiction. Empty containers may be recyclable after appropriate cleaning, or may require disposal as contaminated packaging under local authority guidelines.

Material Identification & Emergency Information

The product is identified by bar code 9300697122070 and product code Bar Code 930069712207001 (SDS). The reference number for professional and emergency responders is SELGHSEN000431 (SDS). The product carries no Hazchem Code, consistent with its non-Dangerous Good classification (SDS).

Emergency contact for incidents in Australia is 1800 220 770; in New Zealand, 0800 220 770 (SDS). These numbers provide 24-hour access to toxicological advice and incident management support. The manufacturer, with ABN 67 000 049 427, maintains a street address at 1956 Dandenong Road and a general enquiry line at 1300 555 205 (SDS).

Fire Behaviour & Suppression

In its paste form, this filler is non-combustible (SDS). Once the aqueous component evaporates, however, residual material can burn if ignited (SDS). This matters in fire scenarios where the product has dried on surfaces or in waste — the dried organic components become combustible once water content is gone.

If the material becomes involved in fire, use water fog or fine water spray, alcohol-resistant foam, standard foam, or dry agents such as carbon dioxide or dry chemical powder (SDS). The water content in fresh material assists suppression, since it must evaporate before combustion can occur.

Spill Management Procedures

Spill response scales with incident size.

For small spills, wear protective equipment to prevent skin and eye contamination and avoid inhaling any airborne material (SDS). Wipe up material using absorbent media such as clean rags or paper towels, then collect and seal waste in properly labelled containers or drums for disposal according to local regulations (SDS).

Large spills require clearing the area of all unprotected personnel — the material creates slip hazards and exposure risks that need a controlled response (SDS). The product is slippery when spilt and must be cleaned up immediately to prevent accidents (SDS). Response personnel must wear full protective equipment to prevent skin and eye contamination and inhalation of dust or aerosols (SDS). Work upwind or with increased ventilation to keep airborne exposure to a minimum (SDS).

For large spills, cover the affected area using absorbent materials and containment measures to prevent spread before collection.

Suitability Assessment

Selleys No More Cracks RTU Plaster Filler performs well within a clearly defined application range. It is recommended for ready-mixed interior filler applications on plaster (SDS), making it appropriate for:

Repairing cracks in plasterboard walls
Filling nail holes and screw depressions in plaster surfaces
Addressing impact damage to interior plaster
Preparing plaster walls for painting by filling minor imperfections

The 100g package suits homeowners tackling small repair projects rather than commercial contractors requiring multi-kilogram quantities. The ready-mixed format trades extended shelf life for immediate convenience — a reasonable trade-off for intermittent residential use where mixing equipment and specialist skill may be limited.

The product's positioning as an interior plaster filler also defines where it should not be used. It is not formulated for exterior exposure, timber substrates, masonry, concrete, or below-grade applications where moisture ingress or different substrate movement characteristics would undermine performance. The hazard profile also makes it less suitable for environments with young children or individuals with known isothiazolinone sensitivities, unless strict contamination controls are in place.

Selleys No More Cracks Exterior Wood Filler sits within the Selleys brand, an Australian home repair and maintenance label with a broad range spanning adhesives, sealants, putties, and fillers. Within that portfolio, this product occupies the putty and fillers segment, specifically the wall and wood filler subcategory — as reflected in its canonical category of Home & Garden > Wood Fillers & Repair. Selleys positions this product alongside its wider "No More Cracks" line, which the brand name signals is a family of crack-repair solutions, though the knowledge graph available here specifically documents the exterior wood variant in a 450 g tub.

What distinguishes this filler from interior or general-purpose alternatives is its weather-resistant, flexible formulation. Where a standard interior filler is rigid once cured and vulnerable to moisture, this product is engineered to flex as timber expands and contracts with seasonal temperature and humidity changes — a critical requirement for outdoor applications such as siding, exterior trim, and outdoor furniture. It dries to a natural pine colour, which means it is best suited to timber surfaces where paint, stain, or varnish will be applied over the top rather than left exposed.

Someone using this product for an exterior timber repair is likely to reach for a few complementary items. Sandpaper or a sanding block is a practical companion, since the filler is explicitly designed to be easy to sand to a smooth finish once cured. For larger or deeper repairs — the product supports applications up to 10 mm deep — a putty knife or flexible filling blade will make application cleaner. Once the filler is sanded back, an exterior timber paint or stain would be the logical next step to protect the repair and match the surrounding surface. Because the product requires no priming before filling, a dedicated timber primer is not a prerequisite, which simplifies the overall repair workflow.

In short, Selleys No More Cracks Exterior Wood Filler is a specialised outdoor repair product within the Selleys filler range, differentiated by its flexibility and weather resistance, and typically used as part of a broader exterior timber maintenance or painting project.
