Wax, polyurethane varnish or Forum Favourite Osmo it. Acrylic double sided tape will stick to all of them so no need to remove it. Probs stick best to PU though.
Alternatively just flip the top over when come to lino it, then you have a nicely finished underside and fresh wood to stick to.*
*that’s if you’ve been lazy and not sealed the underside, which will probably be fine, but could lead to cupping if the top isn’t screwed to a solid frame or is quite thin. It’s a bit of a gamble rally. I finished two bits of 30mm oak block worktop on one side only recently, one was fine, other cupped 3 or 4mm. I’ll let you know what the 30mm radiata pine table tops I did last night look like when I get to the workshop…
Speaking of which, a question I've been meaning to ask - I have a desk which is a piece of that block laminated pine. Eventually I'd like to put a piece of lino on it but won't get round to it for a while (year or two). The surface is a little bit fuzzy and I'll sand it - I'm considering whether or not to give it a bit of wax too or whether I will regret that when it comes to sticking lino on (with double-sided tape as @dbr recommendation). There are various wax and polish removers/solvents, or if I don't go heavy will that even need necessary?
