Levelling compound for use over tiles

ed110220

Quick update, after laboriously chipping up the first attempt I had success on the second attempt yesterday.

I used Mapei Ultraplan 3240 mixed with a mixing attachment on a cordless drill. After reading quite a few reviews I used more water than recommended in the instructions (3 L instead of 2.25 L) and refrigerated the water first to lengthen the setting time. Probably used a bit too much water this time but it did level well and has set so I'm happy.
