Thread: joint filling query

I use Timbermate. It’s available in a range of colours, is water based and dries quickly.

yep timbermate is my chosen method. Takes stain reasonably well and like your powder stuff if it dries out can be reconstituted.

In our home centers there are a couple of brands of "Stainable" wood filler. The products accept stain rather well however you MUST stain. Just a varnish or poly doesn't look that well.

the problem I seem to get is that when I fill the hole, it of course spills over beyond the edge of the hole, and whilst I can sand it all flat, the filler has seeped into the surrounding wood leaving a stain that does not come out unless i sand down below that layer.

Cover the area you want filled with blue painters tape. Cut the area you want to fill out with a sharp knife (scalpel).

This will help fill without spreading, plus the thickness of the tape lets you overfill a bit, so it sands back neatly.

The other option, if you have a fine saw, is to cut a kerf and fit a self-made strip of veneer (using the original timbers offcuts) into the kerf. If your veneer is a bit thick, thats OK, use a sanding block to give it a slight taper, this way when you force it in, it will wedge itself in hard right to the edges, leaving no seam.

Cant say i’ve had that problem with Timbermate. It’s not that liquid to cause staining.

So far I've hardly done any filling but when I did use Timbermate it didn't stain anything. Perhaps you added stain to the fuller and that stain has leeched into places it's not welcome?
They sell Timbermate in a large range of hues to help you match with your wood species. So that would get you half way.

Can you afford to give that joint a hit with a sander? OK I know you shouldn't, but if you can remove some material at the joint site then just feather back on both sides so its a gradual "drop" to the intersection. Being quite a grainy piece sanding out the chips/holes is masked by the grain.
Filler will always look like filler even if it is a matching colour
