Metolux wood filler is one of those products that solves a problem most tradespeople have quietly wrestled with for years. Two-part fillers are the go-to for serious wood repairs, but getting the hardener-to-resin ratio right by eye is where things go wrong. Too little hardener and it stays tacky. Too much and it kicks before you have finished working it. The Metolux 2 Part Pre-Mixed Wood Filler removes that variable entirely by using a ChubSeal cartridge that dispenses both components in the correct ratio every single time.
This is a proper, chemical-cure filler rather than a basic water-based paste. That matters because the result is a genuinely hard repair that can be sanded, shaped, drilled, and painted. It will not shrink back or crumble out of deeper fills the way single-part fillers sometimes do. The styrene-free formula means there is no sharp solvent smell hanging around while you work, so internal applications are not a problem. Kitchens, joinery, skirting boards, door frames, window boards — all fine.
Where Metolux Wood Filler Really Earns Its Place
External timber is where this product comes into its own. Once cured it is weatherproof, which means it holds up in exposed locations where a standard decorator’s filler would soften, crack, or fall out within a season. Fascia boards, external door frames, window sills, garden joinery — anywhere the repair will see moisture, temperature swings, or direct weather. Pair it with a good exterior primer and a properly cured Metolux repair should outlast the timber around it.
The cartridge design is worth mentioning because it is genuinely practical on site. The non-cut sealing cap means you do not need to dig hardened filler out of the nozzle next time you reach for it. Re-cap it and it stores without waste. For anyone who uses two-part filler regularly, that saves both material and the low-level frustration of half a tube going solid in the van.
Sanding back is achievable within 15 to 30 minutes of application, which keeps the job moving. Available in Natural and White to suit different timber tones.
Pro Tip: Warm cartridges dispense more smoothly in cold weather, so keep the tube in your jacket pocket for five minutes before use on winter jobs rather than reaching straight for the van floor.
Metolux 2 Part Pre-Mixed Wood Filler is used wherever a tough, lasting repair to timber is needed. Internal joinery work such as skirting boards, architraves, door frames, and stair components benefit from its hard cure and sandable finish. Decorators and carpenters use it to fill knot holes, splits, dents, nail holes, and areas of localised rot damage before priming and painting.
Externally it is a reliable choice for fascia boards, window sills, external door frames, and garden structures where the repair will be exposed to the elements. The weatherproof cure makes it suitable where a standard decorator's filler simply would not last.

Weatherproof for external use
Styrene free formula
ChubSeal re-sealable cartridge
Available in Natural and White
Not suitable for: Not suitable for structural repairs to load-bearing timber or as a replacement for proper rot treatment where active decay is present. Will not adhere well to surfaces contaminated with grease, wax, or loose paint.
Dispense the filler directly from the cartridge onto a mixing board or card and blend the two components thoroughly for around 30 seconds until the colour is uniform with no streaks. Work quickly once mixed as the pot life is short, particularly in warm conditions.
Apply to clean, dry, bare timber using a filling knife, pressing firmly into the repair to avoid air pockets. Slightly overfill to allow for sanding back. Leave to cure for 15 to 30 minutes before sanding smooth with medium to fine abrasive paper. Once fully hard the surface can be primed, painted, or stained in the normal way.
Prepare the surface by removing any loose material, dust, grease, or flaking paint from the repair area
Dispense both components from the cartridge onto a clean mixing board in the ratio they naturally dispense
Mix thoroughly for around 30 seconds until fully blended with no streaks or colour variation
Apply to the repair with a filling knife, pressing firmly to eliminate air pockets and slightly overfilling the surface
Leave to cure for 15 to 30 minutes depending on ambient temperature
Sand back flush with medium then fine abrasive paper once hard to the touch
Re-cap the cartridge with the ChubSeal cap immediately after use to preserve the remaining material
Prime and paint or stain once the repair is fully sanded and any dust removed
Do I need to measure out the hardener and resin separately?
No. The ChubSeal cartridge is designed so that both components dispense in the correct ratio automatically. You just squeeze them out together and mix on a board. That is the whole point of the pre-mixed system.
Can this filler be used on exterior timber?
Yes. Once fully cured it is weatherproof and suitable for external applications including window sills, fascia boards, and door frames. Apply a good exterior primer over the repair before painting to protect the surface long term.
Is the filler safe to use indoors?
Yes. The formula is styrene free, which means there are no harsh solvent fumes during application. Normal ventilation is still sensible but it is suitable for internal joinery work without needing specialist respiratory protection.
Metolux 2 Part Pre-Mixed Wood Filler is a polyester-based two-component repair compound supplied in a ChubSeal cartridge that delivers a consistent hardener-to-resin ratio on every application. The chemical cure produces a dense, hard repair that resists moisture and temperature variation once set. The styrene-free formulation reduces VOC content compared to traditional polyester fillers, making it suitable for use in occupied or poorly ventilated spaces. Available in Natural and White finishes to suit different timber substrates.
