Hello to all forum members. Currently have a builder in and they have put a tiler in to fit 10x10cm wall tiles throughout the kitchen to eye level, about 15 sq. metres. i have noticed that the tiler is using 2mm plastic cross type pegs and so far covered about 3 sq. metres and is back today. What i'm worried about is, I have noticed that the tiler is placing the x pegs completely flat in the tiles set right in against the plaster / wall, it looks like these are going to be left in place and grouted over, they don't look like they will remove all that easy and removing 15 sq. metres worth seems like it is not going to happen. Is this correct method and what problems could this cause ? Many Thanks in advance, Ron.
