  • Rotten window frame fixing - any pointers greatly appreciated. Maybe @Airhead if you have time to pass on some expert knowledge.

    I patched up a small rotten section a few years ago with hardener and filler but looks like I’m now paying the price for not addressing the issue properly.

    My plan is to use a multi-tool (is the cheapo Screwfix Titan model good enough for this?) to cut out the sections on the base and side panels then patch in new hardwood sections.

    I’m a member of the South London Makerspace so I’m hoping to find some small pieces in the woodshed scrap bin. Are there any wood species that I should use/avoid? I’ll have to get the basic shaping done in the workshop then will get the final fit done at home. I don’t have any planes at home but hopefully a bit of chisel/mutli-tool work will suffice.

    Any paint recommendations for finishing? I think last time I used Zinsser Permawhite.

    Timing isn’t great with the rain coming but hopefully it won’t take more than a weekend to complete.

  • Based on what I can see from the photo it looks pretty decent.

    Remove the beading completely and replace the whole pieces, not worth splicing anything in for the cost of complete pieces.

    If you use repaircare you can just cut out any rotten wood and use soft or hardwood pieces to save on the resin. It's probably worth the price of the starter kit to splice some hardwood in with the resin.

    Paint with Zinsser Aqua BIN primer and Allcoat. I tend to double up on primer/undercoat and top coat so 4 coats 2 of each.

  • Thanks for this, all seems straightforward.

    Would you use undersized pieces of wood then cover everything in repair care? Or should I get the wood as close to a good fit as I can then just fill the small gaps with repair care?

    Edit - I watched a few videos and I think I’ve got a pretty good idea of how it works. I’ll aim for 10mm gaps between my new timber and the existing and finish the outer surfaces with epoxy ready for sanding/painting.
