How do I choose the filler shade?

By the tone after the finish is applied. Most fillers dry a shade lighter and change again under varnish, so test on a small area where the repair will show.

Will varnish and paint hold on filler?

Yes — wood repair fillers are made to be varnished and painted. Let the filler dry fully and sand it back first.

Why did the filler crack as it dried?

Usually it was applied too thick, or the timber still holds moisture. As damp timber dries and moves, the fill splits.

Wood Filler

Wood filler fills a dent, split or screw hole and sands back flush with the surface — with the right shade, the repair disappears. The catalogue holds 20 colours, from oak, walnut, pine and beech to black, white and grey.

Choosing a shade and applying it

Match the shade not to the bare timber but to the tone under the finish that will go over it, since most fillers dry a shade lighter. On visible work, test on a small area first.

Build the filler up in layers: filling a deep void in one go lets the surface skin over while the inside stays soft, and the repair sinks later. Once dry, sand it back flush with a fine grit.

Timber shades: oak, walnut, pine, beech, hornbeam, birch, cherry, mahogany, wenge, ash, maple, pear.
Plain colours: white, cream, grey, black, red, orange, natural.
Fill deep voids in layers.
Sand back with a fine grit (180-240) once dry.
