Hi can I check am I able to just buy some varnish and varnish my timber skirting of my flat? After renovation I tried cleaning the dust n powder stains but it can’t come out. I thought of just giving it a coat of vanrish so it looks new. Any Bros does that? Thanks

Since it's after renovation and you already tried cleaning and it still don't come off, get the contractor to make good.

I don't think the varnish will hide the powder stains. But if you need to do it yourself, you probably need to use a fine sand paper to remove the stains first, then apply the varnish.

You should test at a not obvious location first.
