I always top coat with the same mix once the first coat is touch dry (doesnt leave finger marks in it when touched) but looking through alot of previos comments, i'm starting to think this isn't the norm or at best seems to be the way a novice would go about things.... to myself (a complete newbie and novice) the thought of doing a new mix for the 2nd coat would seem very odd... i suppose i like the stiffness of the remaining mix and with lots of pressure thats what gives me a nice finish not sure that would be possible with a fresh wet mix for me.... any way just wondered what your thoughts were the people out there every day doing it full time and any newbies out there whats the norm???????? pro's/cons?????
