I have a small 2-3mm gap at one end of a kitchen cupboard to floor plinth - tiler didn't straighten the floor before laying tiles.
I'm not going to buy another plinth and I really don't want to use a silicone bead to sal the plinth to the percelain tile floor (it will be impossible to remove without causing damage I guess).
Is there a sealant I can use that will do the job in terms of hiding the gap (white) and giving some resistance to water seeping into the plinth via the grout joints?
