When we moved into our house, the banisters had been painted white, not very well (it looked like the previous owners had just painted everything in the house with white primer). The paint started to flake off and generally looked a mess, so I started sanding it and realised that there is nice wood underneath the paint.
So, I'm gradually sanding it all back and want to stain it once I'm finished, but I'm very confused about my options.
First of all, there are a couple of bits where the wood is a much lighter type than the rest. I'm not sure what the main wood is; it's fairly light in colour, but not totally pale, whereas there are a couple of bits of trim which look to have been added later, and they're some sort of quite pale wood. So, I'm thinking they may need a couple of layers of colour to bring them to the same tone as the darker bits.
Secondly, what do I actually use to stain it? I looked in Homebase, but all the wood stain they had was exterior stain - can I use that or do I need interior stuff? They had wax and oil and for interior use - am I meant to use that instead?
I had imagined that I'd buy some sort of medium oak stain, and do a layer of that everywhere, plus an extra layer on the lighter bits, and then maybe some sort of protective layer of something to finish it off and make it nice and shiny, but now I don't know what I'm supposed to do! Please help!
