More specifically, do you lay the tile right against the floorboard with no groat visible? Or would you put a spacer in between the floorboard and the tile so that it you have grout along the edge?
The best way is to remove the baseboard trim and tile under it leaving a 1/4 to 3/8 gap to the wall. Then cover that with the trim. If you absolutely do not want to remove the trim then you need to put a spacer along the wall so that all the tile is layed uniform. A batten as the previous poster stated is a good idea. You then want to remove the batten when the tile is set. Do not grout up to the wall however, it leaves no room for expansion and you will end up with cracked grout or worse, ballooning in the middle. You want to buy a caulk that is the same color as the grout (they sell them at most home improvement stores). Use this to caulk the seam at the edge between the tile and the trim.
That is what base boards and shoe molding are for. To cover the gap in the flooring material at the wall.
put skirting boards to the floor. Batten the wall half a tile up from the skirting start laying your tiles upwards from the batten when you`ve placed all your tiles let them set, now cut your tiles from the bottom of the tile to the skirting. Thats how we would do it anyway.
when i lay tile i cut as close as i can to the base board it looks much better than having a wide grout line next to the base board that's how it should be done good luck
It is honestly all up to the look you prefer. I for example always remove the baseboards and put a quarter inch space in between the tile and the wall (gives you a seamless result). In doing so, when you put the baseboards back on the wall - any mistakes are hidden - and the job just looks more complete. You can however go the route you are talking about (I've seen it done) - and personally I think that adding a grout line is the way to go - mainly b/c not all walls are square - and the likelihood of you having a seamless edge against the baseboard is slim. Good luck,
