I used some Mapei Ultimate leveler 1210 yesterday. Today I've noticed that in an area of it a skin 1mm thick has raised and separated and can easily be scraped off. When I laid it there was quite a lot of air bubbles rising in it and I went over with a steel float to try and get rid of them, now I remember my bricklayer father telling me that a steel float brings cement to the surface and a wooden one sends it down, could this be my problem and in future should I just leave it alone?
