sweep then vacume floor
apply primer andfollow instructions
lay a good quality leveler again follow instructions. check when set,after about 2 to 3 hrs its level if any high spots shave off with side of level.
when the area is flat my advice would be to dry lay your tiles then take up, and using an adhesive such as ardrit x7 slow set or tile master setaflex, lay the tiles from the rear to the front, a row ata time, use a 8 mm trowell and with your level check for flatness i wouldnt use clips
prime leveler and back skim tiles good luck
