Just looking for some advice regarding a balconey i'm quoting for. I've never tiled a balconey before, its only small, 4m2 in total. I need to level the floor of the balconey first because its really uneven, i was wondering if there is any special slc i should use? or what is the best one in your opinion because i'm not the best when it comes to self levelling compounds. Do i need to use any special addy or just something like BAL rapid flexi? What is the best sealer to use? Cheers.
