Hello All,
I have just been given the contract for 6 flats in my local area by an established builders firm. The tiling required is walls and floors for bathrooms and kitchens, using mostly large porcelain tiles.

My question is that the builders want all external miters put in without trim, and having to cut the tiles at a 45 degree angle.
Because of this and being completly inexperianced with these i negotiated for day rate untill i gathered speed.
