I have used Liberon floor sealer on our floor, once again used as a walkway, did three or so coats and am glad to say I have no wear problems at all (bar the sofa coaster falling apart and leaving a screw sticking out) Gave it a coat of the Liberon wax afterwards to make it extra slippy, that has now worn off but the floor still looks great. Just about to do the same again in a different room. Use a little at a time and don’t rush. Also your knees will hurt. I found that if you wet (I guess white spirit would do the same) the floor unsealed you would need to rub it down as the wood fibres seem to swell. Makes for a very smooth piece of wood. Wood floors are great.
