Hi @DonnaL thanks for the complement re my kitchen tiles. The paint on the tiles is only about 3 months old so hasn't stood the test of time yet. They clean up very well, although I am a household of only 1, but I do cook every day. If I look closely at the tiles behind the cook top I can see some a lone tile that had a pattern on it and it's a bit rough, but honestly, unless you are looking for it you would never know.
Preparation is time consuming of course but once I realised I didn't need to sand as much as I was trying to, it was a bit quicker. I downloaded the instructions from the Dulux site and followed them by the book. You have to remove all the silicone which I found a pain! Painting the tiles was the easiest part and I had plenty of paint left over, so used it up having a go at painting some laminate shelves in the laundry, even though Dulux has a different paint for laminate. (I painted the tiles in in my very small laundry as well). I have a heavy container of dog food stored on one shelf which I slide off twice a day to access it to feed the dog and no scuffs or scratches. I even used up the last bit painting some clay garden pots, I have no idea how they will last outside, but they look good so far! So I hope this helps. Good luck!
