I did the job myself, started last Friday night and did a few hours then a few more on Saturday and finally finished on Sunday afternoon, all in all I would say it took me about 12 Man hours for the whole thing including grouting. The finished job looks great and I am glad I took it on myself, it cost me 80 quid for adhesive, 10.99 for grout, 22 on a laser level and 4 quid on spreader plus another few quid here and there for spacers.
I would recommend anyone with a reasonable amount of DIY experience to take on a job like this. For those of you thinking about doing it here a couple of things I have learned from my experience.
1. Bond the concrete floor(this is essential) PVA 1 Part Water 5 Parts, I used a soft bristle sweeping brush to do this and it worked a treat.
2. Laser line level helped my get a straight line along my wall allowing for the width of skirting board to take up any unevenness in the wall.
3. I used BAL Adhesive and grout, The Adhesive was Rapid Set and I was a little worried about it going off to quick but because I had bonded the floor I had plenty play time with the tiles.
4. You need a big and I mean big bucket to mix the adhesive in and the stuff is messy as hell so don't think you can do a little bit here and there or you will just spend all your time cleaning up!
5. My top tips I guess are not to spend too much time messing around with each individual tile because you don't really know if the one you have laid is right until you have laid the next one or two next to it if you know what I mean. Also clean out the adhesive between the gaps after a few minutes because one it goes off its hard to get out before you grout.
Hope this helps
