I hope your slab laying is better than your grammar. Please try to punctuate your posts, thereby making it more likely that people who know the answer will bother to reply.

Make sure the concrete beneath is nice and clean. I would then paint it as I went with a neat cement slurry. Don't bother with the water proofer. Dont butt-join them unless they are very straight sided and the manufacturer states they are suitable for such a technique.

A 4 to 1 mortar is fine.
