Repair hole in weatherboard

[gt88]

We renovated our bathroom and moved the basin waste pipe. This has now left a hole in the weatherboard which is about 50mm in diameter. What is the best way to cover/repair this hole?

Is the weatherboard painted? If it is, just use builder's bog or KH, whatever it is called, that will fix it, I'd say.

Cut a plug roughly the size of the hole. Bevel the edges so you can push it in without going right through. spread a bit of buiders bog around the edge of the hole and the edge of the plug, then push it firmly in. Allow the bog to harden, then sand it all back level

I did some shape from timber that pretty much fit with tapered edges. Stuck it in, sealed rest with builders this K&H filler, cheaper than builders bog. Polyester resin stuff. Then sand it, paint and you can´t tell. If its to big the bog will collapse in the hole, takes 1kg to eventually fill it ,-)

Use a couple of ice cream sticks inserted in parallel but with a bit of gap between them: piece of string + weight on each, apply some glue to the faces, insert in the hole, allow to dry. That's a base for a thick filler.

Good excuse to eat ice cream.

Back in the days of make do and mend, they used to cut a square out of a steel can, file off the edges so they were not sharp and then tack that over the hole. To be followed by a coat of paint. Amazing how 'invisible' it becomes

that didn't work for m, looked dodgy. If you got time to down a can you may well whizz up some timber shape. One more task for the angle grinder, sand them to shape using $2 shop flap disks...

or buy a length of weatherboard and just replace it. Prob cost much the same as the bog....and ice creams etc.....
