Query: Not enough information

I recently order this video and am very disappointed. I am a beginner and the video doesn't seem to cover enough information to make me confident in finishing concrete. There is very little detailed information. James Beville appears to be working at a job site and just explaining what he is doing to someone who happen to be videotapping it(not very professional video editing). There is no information on how to avoid problems such as scalling or cracking. The video is about 30 minutes long making it about a dollar a minute. I found more information for free on the net or spend your money on a good masonry book which will probably be less.
