Full details

Bartoline Ready Mixed Wood Filler is the ideal solution for homeowners and DIY enthusiasts looking to repair interior and exterior wood surfaces like door frames and skirting boards.

FAQs

Can I use this on exterior window frames?

Yes, but you must seal it with an oil-based paint or varnish once cured to protect it from moisture.

How long does it take to dry?

Drying time depends on depth and environmental conditions, but layers should be allowed to set fully before subsequent applications.

Can I stain this wood filler?

Yes, once the filler is fully cured and sanded, it can be stained or varnished to match your wood.

Do I need to mix this with water?

No, this is a ready-mixed product and should be used directly from the tub.

What should I do if the wood is rotting?

You must remove all rotten wood down to solid, healthy timber before applying the filler.

How thick can I apply each layer?

It is recommended to apply layers no thicker than 6mm for optimal curing.

Troubleshooting

Filler is cracking after drying

The layer was likely applied too thick. For deep repairs, use a multi-layer approach of 6mm or less.

Filler is falling out of the hole

Ensure all loose debris and rotten wood were fully removed and the cavity was clean before application.

Surface is uneven after painting

Ensure the filler is fully cured and sanded level with the wood grain before applying any topcoat.

Pros and Cons

Pros

  • Ready to use with no mixing required
  • Flexible when cured to prevent cracking
  • Can be finished with paint, varnish, or stain
  • Suitable for both interior and exterior use
  • Easily sandable for a smooth finish

Cons

  • Requires oil-based sealant for outdoor projects
  • Deep repairs require multiple layers with drying time
  • Cannot be used to repair rotting wood without prior removal

Setup, Compatibility & Care

To ensure the best results, start with proper surface preparation. The target area must be clean, dry, and entirely free of dust. You must excise any rotten wood completely; applying filler over decay will lead to premature failure of the repair.

For outdoor use, the filler requires extra care: after the filler has cured and been sanded, you must apply an oil-based paint or varnish. This step is non-negotiable for moisture resistance. Keep the tubs tightly sealed when not in use to prevent the remaining filler from drying out. Store in a cool, dry place away from extreme temperatures.
