I'd replace what you can. Sam There is a much stronger glue than liquid nails. It's called T Rex and will stick your timber to the concrete. Cheers Simeon 1 1545 l spoke to my plumber we decided to replace the rusted screws and keep all the screws with no rust, it will only cost a few hundred 7 8749 |
