Description
Selleys Plasti-Bond Heavy Duty is a two part polyester filler built for repairs that have to carry load, not simply look tidy. Once the hardener is stirred through, it firms up to a dense, rigid mass in about twenty minutes without the shrinking or cracking that catches out lightweight patching compounds, and it holds its shape well enough to be drilled, tapped and fixed into after curing. The 400g can covers the middle ground jobs that a small pack runs short on.
What it is
The pack contains an off white polyester putty base and a separate hardener that is mixed in immediately before use. Working time is short, around five minutes at normal room temperature, so the product is mixed in batches rather than all at once. Cured Plasti-Bond can be sawn, drilled, filed, sanded and painted, and the base can be tinted with cement oxides or paint tinters before the hardener goes in if a coloured finish is wanted.
Where to use it
Indoors: filling holes, cracks and splits in walls, ceilings, floors and doors; rebuilding worn areas around hinges, locks and door handles; making good chipped tiles and ceramics; anchoring bolts and fixtures into masonry; stopping countersunk fastener heads flush in almost any material.
Outdoors: patching chipped concrete steps and paths, repairing galvanised guttering and downpipes, and restoring fibreglass, timber and metal on furniture, sporting gear, cars, caravans and boats above the water line. Outdoor repairs should be painted, since the cured filler can discolour if left bare in sunlight.
How to use it
- Prepare the surface so it is clean, dry, unpainted and free of grease or oil. On steel or aluminium panel work that will see vibration, punch or drill the area first to give the filler a positive key.
- Stir the base thoroughly, then blend in the hardener, working the mix from side to side until the colour is completely uniform. Extra hardener speeds the set in cold weather; less hardener buys time across several separate fills.
- Apply with a putty knife or spatula, pressing firmly into the repair and slightly overfilling to leave material for sanding. Feather the edges as you go.
- Take off most of the excess with a Surform or file between roughly twenty and thirty minutes, while it is firm but not yet rock hard. Once fully hard, finish with ordinary files or sandpaper.
- Paint with water based or oil based paint. Clean tools with mineral turps before the product cures.
Important notes
- Not suitable for continuous immersion or for joints that need to stay flexible.
- May not adhere to polyethylene, polypropylene or PTFE.
- Can discolour if left unpainted outdoors.
- Mix only what you can apply inside the working time; cured material cannot be re-softened.
- Replace the lid firmly after use and store the can in a cool place.

Safety
Polyester fillers and their hardeners are flammable and give off solvent vapour while curing. Work in a well ventilated area, keep the product away from sparks, flames and other heat sources, and wear gloves and eye protection when mixing and applying. Avoid prolonged skin contact and wash any splashes off promptly. Keep out of reach of children, do not allow washings to enter drains or waterways, and dispose of unused material and empty containers in line with local regulations. Consult the current Selleys Safety Data Sheets for the base and the hardener before use.
