Product Overview

Selleys Plasti-Bond Heavy Duty Bog Resin is a two-pack polyester putty system for filling holes and cracks in building materials. Manufactured by Selleys, a division of DuluxGroup Australia Pty Ltd, it's a high-strength filler aimed at tradespeople and capable DIYers who need repairs that actually hold.

The product is a grey paste with a characteristic odour, insoluble in water. It's one half of a two-pack system — the resin must always be paired with the dedicated Plasti-Bond Hardener, which triggers the chemical curing reaction responsible for the repair's strength and durability. That pairing is the whole basis of how this product works.

How the Two-Pack System Works

Plasti-Bond Heavy Duty Bog Resin cures through a chemical reaction, not simple drying. The grey paste contains reactive polyester compounds that stay stable and workable on their own. Add the dedicated Plasti-Bond Hardener and mix it thoroughly, and a chemical reaction starts. That reaction cross-links the polymer chains, converting the soft paste into a hard, solid mass.

This is a different outcome from single-component fillers like water-based acrylic putties, which cure only by water evaporation. The two-pack polyester system produces a denser, stronger result because curing happens as a chemical process throughout the entire body of the filler, not just at the surface. The result resists shrinkage, holds its shape, and reaches a hardness you can sand, shape, drill, and paint once fully cured.

The hardener must be the dedicated Plasti-Bond Hardener. Using a different hardener — even one that appears chemically similar — risks incomplete curing, unpredictable cure times, and a repair that won't perform. Use the matched components. No substitutions.

Mixing the Resin and Hardener

Getting the mix right is the most important step. Too little hardener and the mixture stays soft or tacky and never fully cures. Too much hardener and the working time collapses, the mixture can overheat, and the cured material becomes brittle. Follow the manufacturer's ratio instructions precisely.

Practical Mixing Steps

Prepare a clean mixing surface. Use a non-porous board — glass, metal, or a disposable mixing palette. Cardboard and porous surfaces absorb the resin and compromise the mix.
Dispense the resin. Scoop out the required quantity of grey paste.
Add the hardener in the correct ratio. Follow the product label instructions for the specific ratio by weight or volume.
Mix thoroughly. A putty knife or spatula works well. Use a folding and spreading action across the full mass of material until the colour is completely uniform with no streaks. Any unreacted resin left from incomplete mixing will stay soft, and the repair won't hold.
Work promptly. Once mixed, pot life — the time you have before the material starts to harden — is limited. Warmer conditions shorten working time; cooler conditions extend it.

Only mix what you can apply within the working time. Any mixed material that has started to stiffen before application gets discarded.

Surface Preparation

The strength of any repair starts with the surface. Plasti-Bond Heavy Duty Bog Resin bonds to clean, dry, and sound substrates. Cut corners here, and even the best filler won't deliver.

Remove all loose material. Crumbling edges, dust, rust, and flaking paint come off before you apply anything. Use a scraper, wire brush, or sandpaper suited to the substrate.
Clean the surface. Wipe away dust and debris. Oil or grease contamination requires an appropriate solvent — clean it properly and let it dry fully before proceeding.
Ensure the surface is dry. Moisture beneath or within the substrate interferes with adhesion and curing. Never apply this product to wet or damp surfaces.
Key the surface. On smooth surfaces, lightly sand or abrade the repair area to create a mechanical key. That extra grip improves adhesion and locks the repair in place.

Surface preparation often takes longer than the application itself. That's fine — it's the step that determines whether the repair lasts months or years.

Application

With the resin and hardener thoroughly mixed, apply the material to the prepared surface without delay.

Press the material firmly into the void. Use a putty knife or flexible spreader to work the mixed resin into holes and cracks. Air pockets weaken the repair and can cause the filler to crack or detach after curing.
Overfill slightly. Apply the material so it sits just proud of the surrounding surface. This accounts for any minor settling during cure and leaves enough material to sand back flush.
Shape before curing. If the repair needs a specific profile or contour, form it while the material is still workable. It's far easier than grinding it back later.
Allow to cure fully. Leave the repair alone during curing. Cure time varies with temperature and the hardener ratio used. The material is ready for sanding and finishing when it is firm and no longer tacky to the touch.

Finishing After Cure

Once cured, the hardened material gives you genuine workability:

Sanded — Work through progressively finer grades of sandpaper to bring the repair flush with the surrounding surface. Start coarser to remove bulk material, finish finer for a smooth surface ready for paint.
Filed or rasped — Shape irregular profiles or remove larger amounts of material quickly where needed.
Drilled or cut — The cured filler takes drilling, screwing into, or cutting with appropriate tools where the repair calls for it.
Painted — Once sanded smooth and dust-free, prime and paint with standard building paints. Priming before painting delivers the adhesion and even topcoat finish that makes the repair invisible.

Don't apply topcoats before the filler has fully cured. Painting over incompletely cured polyester filler traps solvents and undermines both the filler's final cure and the paint's adhesion.

Safety Considerations

Plasti-Bond Heavy Duty Bog Resin is classified as Dangerous Goods Class 3 (Flammable Liquid) and carries the signal word Danger. This classification is legally significant under Australian dangerous goods regulations. Know what you're working with and follow the precautions.

Hazard Summary

Flammable liquid: The resin contains flammable components. Keep away from ignition sources, open flames, sparks, and heat during use and storage.
Skin and eye irritant: Direct contact with uncured resin causes irritation to skin and eyes.
Skin sensitiser: Repeated or prolonged skin contact can cause sensitisation — an allergic reaction that worsens with subsequent exposures, even to small amounts.
Suspected reproductive toxicant: The product contains components suspected of causing reproductive harm, which is particularly relevant to people of reproductive age and pregnant individuals.
Organ damage through repeated exposure: Prolonged or repeated exposure may cause organ damage. This is a hazard associated with chronic exposure, not a single incident.

Required Personal Protective Equipment (PPE)

The Safety Data Sheet specifies the following PPE for mixing and application:

PPE Item	Purpose
Nitrile gloves	Protect skin from resin contact and sensitisation
Safety glasses	Protect eyes from splashes of uncured resin
Overalls	Protect skin and clothing from contact
Safety shoes	Protect feet from spills
Organic vapour/particulate respirator	Protect against inhalation of vapours and particulates

The respirator must meet AS/NZS 1715 (Selection, Use and Maintenance of Respiratory Protective Equipment) and AS/NZS 1716 (Respiratory Protective Devices). A paper mask or standard dust mask does not meet these standards and does not protect against organic vapours.

Ventilation

Use the product in well-ventilated areas. Uncured resin produces vapours that accumulate in enclosed spaces. Working indoors or in confined spaces requires active ventilation — open windows and doors, or use mechanical ventilation — in addition to wearing the specified respirator. Both are required.

First Aid

Skin contact: Remove contaminated clothing. Wash skin thoroughly with soap and water.
Eye contact: Immediately irrigate eyes with clean water for several minutes. Seek medical advice if irritation persists.
Inhalation: Move to fresh air. Seek medical advice if symptoms develop.
Ingestion: Do not induce vomiting. Seek immediate medical advice.

Always refer to the current Safety Data Sheet (SDS) for complete first aid and emergency procedures. The SDS reference number for this product is SELGHSEN000285, issued 29 April 2025, Version 3.1.

Storage and Handling

Store in a cool, dry, well-ventilated location away from direct sunlight and heat sources.
Keep away from ignition sources at all times, due to the flammable liquid classification.
Store in the original, tightly sealed containers.
Keep out of reach of children.
Do not store near food, beverages, or animal feed.
Check shelf-life and use-by information on the product packaging. Polyester resins can change in viscosity or reactivity over time, particularly when stored incorrectly.

Dispose of unused mixed material and empty containers in accordance with local council and regulatory requirements. Do not pour uncured resin down drains or into waterways. The product is insoluble in water but contains components harmful to the aquatic environment.

Common Issues and How to Avoid Them

Repair Remains Soft or Tacky After Curing Time

This comes down to mixing — insufficient hardener, incomplete mixing, or both. Get the ratio right and mix until the colour is completely uniform. If the repair hasn't cured, remove the soft material, clean the surface, and re-apply with correctly mixed product.

Repair Cracks or Detaches

The most common causes are inadequate surface preparation — contamination, moisture, or insufficient keying — or application to a substrate with movement or flex beyond what the cured filler can handle. Polyester putty is rigid when cured and is not suited to surfaces subject to significant ongoing movement. Match the product to the job.

Very Short Working Time

High ambient temperatures accelerate the curing reaction. In hot weather or direct sunlight, pot life can drop fast. Work in the cooler part of the day, keep materials in the shade before mixing, and mix smaller batches when conditions demand it.

Filler Sinks Below the Surface After Curing

This happens when the material wasn't overfilled enough during application, or when air pockets were trapped beneath the surface. Always overfill slightly and press material firmly into voids.
