Manufactured by Selleys, a division of DuluxGroup Australia Pty Ltd, it's aimed at trade professionals and capable DIYers who need a high-strength result. The resin component is a grey paste with a characteristic odour and is insoluble in water — water-based cleanup won't work here.\n\nThe \"two-pack\" part is the most important thing to understand before buying or using this product. Plasti-Bond Heavy Duty Bog Resin is not a ready-to-use filler. It must be combined with its dedicated Plasti-Bond Hardener to start the curing reaction. Without hardener, the resin simply stays as paste — it will not set. That two-pack system is what gives the cured product its strength and durability. The chemical reaction between resin and hardener produces a rigid, stable fill that is considerably stronger than single-component fillers or standard wall putties. That strength is the point.\n\n---\n\n## How the two-pack system works\n\nUnderstanding the chemistry behind Plasti-Bond means you use it correctly and get consistent results every time.\n\n### Resin and hardener: why both are required\n\nOn their own, the polyester compounds in the resin stay in paste form indefinitely. The hardener — sold separately as the dedicated Plasti-Bond Hardener — contains a peroxide-based catalyst that triggers a crosslinking reaction when combined with the resin. That reaction causes the mixture to harden from the inside out, producing a solid, load-bearing fill.\n\nThis is a fundamentally different process from air-drying fillers, which simply lose moisture and shrink slightly as they cure. Because Plasti-Bond cures through a chemical reaction rather than evaporation, it doesn't shrink significantly. That dimensional stability is a key reason it's the preferred choice for structural filling applications where accuracy matters and where the result needs to last.\n\n### Mixing ratio and pot life\n\nThe correct ratio of resin to hardener is critical. Too little hardener produces an under-cured, soft fill. Too much causes the mixture to cure too rapidly, generating excess heat and potentially cracking. Always follow the mixing ratio specified on the product label and hardener packaging. Once mixed, working time — pot life — is limited, typically a matter of minutes depending on ambient temperature. Warmer conditions accelerate the cure; cooler conditions extend working time. Mix only as much as you can apply within the working window.\n\n---\n\n## Applications and suitable substrates\n\nPlasti-Bond Heavy Duty Bog Resin bonds to a wide range of common building materials:\n\n- Holes and cracks in timber, including structural and framing timber\n- Fibrous cement sheeting and boards\n- Masonry surfaces including brick and concrete where a rigid fill is required\n- Metal surfaces when properly prepared\n\nThe product is not water-soluble and, once cured, holds up to moisture — making it a sound choice where the filled area may be exposed to humidity or incidental water contact. It's not a waterproofing product, and sustained immersion or direct water exposure should be avoided unless the cured surface is subsequently sealed or painted.\n\nFor best adhesion, surfaces must be clean, dry, and free from dust, grease, and loose material before application. Any paint or coating that is flaking or poorly bonded must come off before you fill. The filler performs to its full potential only when it bonds directly to a sound substrate.\n\n---\n\n## Preparation and application\n\n### Surface preparation\n\nThorough preparation is the single most important factor in getting a durable result with any two-pack filler.\n\n1. **Clean the substrate.** Remove all dirt, grease, oil, and contaminants. Use an appropriate cleaner for the surface type — sugar soap for painted surfaces, degreaser for metal.\n2. **Remove loose material.** Undercut cracks and holes slightly where possible to create a mechanical key for the filler.\n3. **Dry the surface.** The substrate must be dry. Moisture trapped beneath the filler compromises adhesion and causes the fill to break down over time.\n4. **Sand if required.** Lightly sanding smooth surfaces improves mechanical adhesion and gives the filler something to grip.\n\n### Mixing\n\nWork in a well-ventilated area before you begin mixing. The resin produces organic vapours during mixing and application — see the Safety section below.\n\n1. Dispense the required quantity of resin onto a clean, non-porous mixing board. A piece of hardboard or a plastic mixing palette works well.\n2. Add the hardener in the correct ratio as specified on the label.\n3. Mix thoroughly using a clean, flat-bladed tool, folding the mixture from the edges to the centre. No streaks of unmixed hardener should remain — streaks mean incomplete mixing and will produce soft spots in the cured fill.\n4. Work quickly once mixed. Pot life is limited and the clock starts the moment resin meets hardener.\n\n### Application\n\nApply the mixed filler to the prepared surface using a filling knife or spreader, pressing firmly to ensure full contact with the substrate and to eliminate air voids. Slightly overfill the area — the material sands back cleanly to a flush finish once cured. For deep holes, apply in layers, allowing each layer to cure before applying the next. This prevents heat build-up from a thick mass of rapidly curing material and gives you better control over the finished surface.\n\n### Sanding and finishing\n\nOnce cured — typically within 20–30 minutes depending on temperature and mix ratio, though always verify with current product labelling — the filled area is ready to sand. Plasti-Bond sands cleanly to a smooth surface that takes paint and coatings well. Work through progressively finer grades of sandpaper, starting coarser to remove the bulk and finishing fine. The cured filler accepts most standard paint systems.\n\n---\n\n## Safety considerations\n\nPlasti-Bond Heavy Duty Bog Resin carries significant hazard classifications that every user must understand before handling the product. This is a high-performance chemical system — treat it accordingly.\n\n### Hazard classifications\n\nThe product is classified as **Dangerous Goods Class 3**, meaning it is a **flammable liquid**. Keep it away from ignition sources, open flames, sparks, and heat during storage and use. Do not use near pilot lights, welding equipment, or other ignition sources.\n\nAdditional hazard classifications include:\n\n- **Skin and eye irritant.** Direct contact with the uncured resin causes irritation to skin and eyes.\n- **Skin sensitiser.** Repeated or prolonged skin contact causes sensitisation — over time, even minor exposure can trigger an allergic reaction. This risk increases with repeated use, which makes consistent PPE use essential, not optional.\n- **Suspected reproductive toxicant.** The product contains compounds suspected of causing reproductive harm. Users who are pregnant or planning pregnancy must exercise particular caution.\n- **Organ damage through repeated exposure.** Chronic or repeated exposure to the product's vapours or components causes organ damage. Adequate ventilation and respiratory protection are non-negotiable.\n\nThe signal word for this product is **Danger** — the highest level under the Globally Harmonised System (GHS) of hazard classification, indicating serious hazards.\n\n### Required personal protective equipment (PPE)\n\nThe following PPE is required when handling Plasti-Bond Heavy Duty Bog Resin:\n\n- **Nitrile gloves.** Nitrile provides appropriate chemical resistance to the resin's components. Latex or vinyl gloves are not adequate substitutes.\n- **Safety glasses.** Protection against splashes of uncured resin.\n- **Overalls.** Full skin and clothing protection from contact with the resin.\n- **Safety shoes.** Closed footwear to protect feet from spills.\n- **Organic vapour/particulate respirator.** This is a critical requirement. The respirator must comply with **AS/NZS 1715** (Selection, Use and Maintenance of Respiratory Protective Equipment) and **AS/NZS 1716** (Respiratory Protective Devices). A standard dust mask is not sufficient — an organic vapour cartridge is required to protect against chemical vapours from the resin. When sanding the cured product, a particulate filter is also required.\n\n### Ventilation\n\nAlways work in a well-ventilated area. Outdoors is ideal. If working indoors, ensure cross-ventilation with fresh air. Do not use in confined, unventilated spaces.\n\n### First aid\n\n- **Skin contact:** Remove contaminated clothing and wash affected skin thoroughly with soap and water.\n- **Eye contact:** Immediately flush eyes with clean water for at least 15 minutes and seek medical attention.\n- **Inhalation:** Move to fresh air immediately. If symptoms persist, seek medical attention.\n- **Ingestion:** Do not induce vomiting. Seek immediate medical attention and contact the Poisons Information Centre (Australia: **13 11 26**).\n\n---\n\n## Storage and handling\n\n### Storage requirements\n\nAs a Dangerous Goods Class 3 flammable liquid, Plasti-Bond Heavy Duty Bog Resin must be stored in accordance with applicable dangerous goods regulations:\n\n- Store in a cool, dry, well-ventilated location away from direct sunlight and heat sources.\n- Keep away from ignition sources and oxidising agents.\n- Store in the original, tightly sealed container.\n- Keep out of reach of children.\n- Do not store near food, beverages, or animal feed.\n\n### Shelf life and container care\n\nCheck the product's use-by or best-before date before use. Resin that has exceeded its shelf life may not cure correctly even when mixed with fresh hardener. Replace the container lid tightly after each use to prevent the resin from skinning or absorbing moisture. If hardener gets into the resin container, the entire container will begin curing. Keep the container clean and sealed.\n\n### Disposal\n\nDo not pour unused mixed or unmixed product down drains or into waterways. Cured material can generally be disposed of as solid waste, but uncured resin is a hazardous material. Contact your local council or waste authority for guidance on disposing of hazardous chemical waste. Many Australian councils operate chemical collection programs for household hazardous waste.\n\n---\n\n## Tips for best results\n\n- **Temperature matters.** The ideal application temperature is between 10°C and 35°C. Below 10°C, curing slows significantly and adhesion is compromised. Above 35°C, pot life shortens dramatically. Know your conditions before you start.\n- **Use a disposable mixing board**, or one that can be cleaned immediately after use. Once the filler cures on a surface, removal is extremely difficult.\n- **Mix slowly and deliberately** to avoid whipping air into the mixture. Air bubbles in the applied filler create weak points in the cured fill.\n- **Layer deep fills.** For holes deeper than approximately 10 mm, build up in layers. This prevents exothermic heat build-up and allows better control over the finished surface.\n- **Label your hardener.** Always keep the Plasti-Bond Hardener clearly identified and stored separately from other hardeners. Using the wrong hardener results in a failed cure or unpredictable chemical reactions.\n- **Clean tools immediately.** Mixed filler cures quickly. Clean all tools with an appropriate solvent — check the product label for the recommended solvent — before the material hardens.\n\n---\n\n## References\n\n- [Selleys Plasti-Bond Heavy Duty – Selleys
