Before you put any sort of underlayment, adhesive or floor covering onto a concrete subfloor, you need to make sure the surface is suitable for the specific material that will go on top.

If the surface isn't suitable, you have to decide what treatment to apply to solve the problem.

Often the only solution is to remove the surface layer until you expose clean, sound concrete.

Your trainer may ask you to keep a log book of the work you do on-the-job that relates to these tasks. This will help them to see whether you have had sufficient practice in the full range of activities needed to satisfy the competency requirements, and to determine when you'll be ready to undertake the assessment events.
