Wood Fillers

Wood Fillers for Furniture, Flooring and Timber Repairs

Wood filler is used to repair holes, cracks, gaps and other imperfections in timber before finishing. Our range includes wood fillers for furniture, flooring, joinery and general wood repairs, with different types available for interior and exterior applications.

Depending on the repair, you can choose from traditional wood filler, two-part filler, grain filler, wax filler sticks, shellac filler sticks and specialist products for particular types of timber repair.

Interior Wood Filler

Interior wood fillers are suitable for repairing imperfections in furniture, doors, flooring and other indoor timber surfaces. We stock fillers in a range of colours, making it easier to choose a shade that works with the surrounding wood or existing finish.

Products such as Osmo Wood Filler, Liberon Wood Filler and Brummer Stopping Wood Filler provide different options depending on the type of repair and finish required.

Exterior Wood Filler

For outdoor timber repairs, choose a wood filler specifically intended for exterior use. Exterior fillers are formulated for applications where the repaired timber may be exposed to changing conditions.

Always check the manufacturer’s instructions to confirm that the filler is suitable for your particular timber, location and intended finish.

Wax Filler Sticks for Wood

Wax filler sticks are particularly useful for filling small holes, scratches, dents and other minor surface damage in finished wood. They are available in a variety of colours and can be useful when carrying out localised repairs without completely refinishing the surrounding surface.

Our range includes Liberon Wax Filler Sticks, soft wax filler sticks and hard wax filler sticks, together with applicators and accessories for carrying out repairs.

Shellac Filler Sticks

Shellac filler sticks are another option for repairing and filling imperfections in finished timber. They are commonly used for furniture and restoration work where a more traditional repair method is appropriate.

Wood Grain Filler

Grain filler is used to fill the pores of open-grained timber before applying certain finishes. This can help create a smoother surface when preparing wood for polishing and finishing.

Rustins Grain Filler is one of the specialist products available in our range for this type of application.

Two-Part Wood Filler

Two-part wood fillers are supplied with a separate hardener and are used where a more substantial repair is required. They can be suitable for repairing deeper damage and rebuilding areas of timber, depending on the particular product.

Always follow the manufacturer’s instructions for mixing, application and drying before applying a two-part filler.

Filling Gaps in Wooden Floors

Some specialist fillers can be used for filling gaps between floorboards before refinishing. Filler Gel, for example, can be combined with suitable sanding dust to create a filler that can be matched to the surrounding floor.

Floor repairs require the filler to be compatible with both the timber and the subsequent finish, so check the product instructions before use.

Choosing the Right Wood Filler

The right filler depends on the size and type of repair, whether the timber is finished or unfinished, the location of the repair and the finish you intend to apply afterwards.

For small repairs to finished furniture, a wax or shellac filler stick may be appropriate. For larger repairs, a conventional or two-part wood filler may be more suitable, while grain filler is intended for a different stage of the finishing process.

Always check the manufacturer’s instructions and test the product on an inconspicuous area where possible before carrying out a visible repair.

Frequently Asked Questions

What type of wood filler is suitable under hard wax oil?

Choose a wood filler that is compatible with the timber and the finish you intend to apply. Some fillers can be sanded and finished with hard wax oil, while wax and shellac filler sticks are generally more suited to localised repairs on already finished wood. Always check the manufacturer’s instructions before applying the finish.

Can wood filler be stained?

Some wood fillers can be stained, but the result can vary depending on the type of filler and the stain being used. If you intend to stain the repaired area, choose a filler specifically suitable for staining and test it on a spare piece of wood or inconspicuous area first.

Can wood filler be used outside?

Yes, but you should use a wood filler specifically intended for exterior applications. Exterior timber is exposed to moisture and changes in temperature, so an interior filler may not be suitable. Always check the product description and manufacturer’s instructions before using a filler outdoors.

What can I use to fill nail holes in wood?

Small nail holes in unfinished wood can usually be repaired with a suitable wood filler. For finished furniture or timber where only a small local repair is required, wax or shellac filler sticks can also be useful. Choose a colour that closely matches the surrounding wood or finish.

What can I use to fill gaps between floorboards?

Some specialist floor fillers can be used to fill gaps between wooden floorboards. Certain products can be mixed with suitable sanding dust to help create a closer colour match to the surrounding timber. Check that the filler is suitable for flooring and compatible with the finish you intend to apply.

What is the difference between wood filler and grain filler?

Wood filler is generally used to repair holes, cracks and other imperfections in timber. Grain filler is used to fill the pores of open-grained wood, usually as part of preparing the surface for a smooth finish. They are intended for different stages of wood preparation and finishing.

When should I use a two-part wood filler?

Two-part wood fillers consist of a filler and a separate hardener and are generally used for more substantial repairs. They can be useful where a deeper or stronger repair is required, depending on the particular product. Follow the manufacturer’s instructions for mixing and application.

Can wood filler be sanded?

Many conventional wood fillers can be sanded once they have dried or cured sufficiently. The amount of sanding required depends on the product and the repair. Follow the manufacturer’s instructions and avoid sanding until the filler is ready.
