Australian Wood Fillers

Postby MickinOz » Thu Mar 05, 2020 10:27 pm

Aussie members - what's a good exterior grade wood filler?

The skin will be structural ply glued and stapled.
Will be sealing with polyurethane (the mix), gluing and stapling the skin to the frame, then filling nail/staple holes, knots and splits, then painting.
Want to be able to get it from the hardware store.

I'm sorta conflicted - good 'ol no more gaps is flexible, sticks like sh!t to a blanket, is cheap and paints well.
Or there is builder's bog - polyester resin with various fillers.
Or is there something better?

Are you bothered about blending into the wood or not?
For blending small areas I like keeping sawdust from my ply and mixing with PVA wood glue. Large areas spend the extra on Sikaflex. No more gaps is fine on stationary stuff indoors but is not right for the Teardrop. (I tried it)

I've been using the PVA with sanding dust, thought maybe I should use a proprietary product.
Dunno whether I'm doing it wrong, but If I use PVA and wood dust at a mixture wet enough to tool into a crack or hole, it sets almost clear.
Maybe if I wet the dust with water then added the PVA?

I just put enough glue in to make it bread dough consistency

Not sure on the "large areas spend the extra on Sikaflex" ?
Is there a sikaflex wood filler?

By large areas I meant a long join like where the wall meets floor or a knot where the center has come out. They don't market something specific as a wood filler. Sikaflex joint sealer comes in a couple of colours. There is a brown I have seen a couple of times but of course when I wanted it I could only get the beige.

Now I see.
I'm not having much need to fill joints, I'm pretty lucky with the range of tools I have for cutting them nice and accurate.
And the sika bond tech grip is amazing stuff, should the joint be a little less than perfect.
I have the Sika 292 for sealing seams as required, like where two sheets necessarily meet on the skin, and I may run around the floor to wall junction.
Even as I was thinking about using no more gaps, It never occurred to me to try the 292 for sealing up knots.
Good thing you are here to set me straight.
