Fossil, it's osmo oil I'm using, I think I read about it on here! It's gone one fine, and the builder has done all the edges for me, so panic over! Osmo has made the worktops very dark though, when I think I preferred them in their raw state! Ah well.
Ideally yes, all cut edges should be sealed, and I would have tried to oil underneath before fitting.
If it is now fitted I would try your best to oil as much as you can. It will be ok, just could have been better. The builder should have done it himself before fitting, or given you time to do it beforehand.
I currently have a new walnut worktop on my kitchen floor, upside down, so I can oil it, will then do other side before fitting. Keep stubbing my toe on it!
Title says it all....the builder has put in the new oak worktop next to the sink, and I can't access the edge to oil it for the first time. Does that matter? I will oil the rest of it and he will put a silicone sealant on that edge but should it really have been oiled first.
Also, do I need to oil the underneath e of the worktops? I.e. the pits that won't be see that are inside the cupboards?
