The 69-year-old guitarist has vowed never to reform with his two surviving bandmates Roger Waters and Nick Mason, saying it would be ''fakery'' for the rockers to reform because the band has ''run its course''.
He said: ''I'm done with it. I've had 48 years in Pink Floyd - quite a few of those years at the beginning, with Roger.
''And those years in what is now considered to be our heyday were 95 per cent musically fulfilling and joyous and full of fun and laughter.
''And I certainly don't want to let the other five per cent colour my view of what was a long and fantastic time together.
''But it has run its course, we are done - and it would be fakery to go back and do it again.''
David - who last shared a stage with Roger and Nick in 2011 - continued to say it would be ''wrong'' to reform without their late keyboard player Rick Wright, who passed away in 2008.
He explained: ''And to do it without Rick would just be wrong.
''I absolutely don't want to go back. I don't want to go and play stadiums ... under the [Pink Floyd] banner. I'm free to do exactly what I want to do and how I want to do it.''
And while there is huge demand from fans for the 'Another Brick in the Wall' legends to tour once more, David said it's not his problem.
He told Classic Rock magazine: ''Obviously I accept there are people who want to go and see and hear this legend that was Pink Floyd, but I'm afraid that's not my responsibility.
''It's just a pop group. I don't need it. I don't need to go there.
''I'm not being coy or difficult - I just think that at my age I should do whatever I really want to do in life.''
