Common Sence is not Common

Boy oh boy - it is true the days, weeks months fly by faster & faster.  Last week we had some gorgeous clients with really interesting jobs.  The guys went out to waterproof a deck - 26 m, unfortunately the concrete guys had left quite a few rough spots & lumps & hollows.  The guys spent 4 hours grinding to get it a little smoother ready for the tiler to pop a self leveling compound on the surface to prepare for our waterproofing.  I forget to ask the simplest questions when booking jobs, Like - is the surface prepared for us?  If I had only asked that, the client may have double checked everything.  Anyway they are off today to do the waterproofing - weather pending - it looks like rain - but the forecast is good.
