To fill or not?

[lloyda]

Repainting garage fascias, and I've had to remove a previous repair on the top edge which is about 10mm x 200mm. Is this gap ok for two part filler, built up in a couple of layers? Or should I glue in a new piece of timber cut to the shape of the hole?

Thanks

New piece of timber sounds preferable.

You need to ensure that you remove all of the rotten soft timber. An oscillating saw is ideal.

I use epoxy resins to splice in the new timber. The polyester resins filler that you are considering is not flexible, it would be fine indoors, but not outdoors.

The downside to epoxy resins is that they are more expensive and in most cases you need a special skeleton gun.

My goto brand currently is Oxera https://www.oxerarepair.co.uk/oxera-online-shop but you will need a tube of 1 hour and the gun- the total being £25 + £32.

Repaircare do however sell an epoxy resin that works with a regular caulking gun.

If you do use an epoxy resin, make sure that you mix it thoroughly, unlike the other filler, if not mixed correctly, it will not cure.

For anyone who comes across this, worth pointing out that you can buy oxera 4hr in tubs so you don't need a gun.

Please do let us know how you get on with the tubs. I have long wondered how one mixes it accurately without mixing the whole tub in one go.
