SBR & Cement Slurry for patio

Hi,

We have a very solid but rather ugly patio - several different materials have been used ( paving slabs, concrete, various repairs ) so the colours are very uneven. I'm guessing this is a silly idea because I haven't read about it anywhere, but could I just mix up a cement and SBR slurry and apply a thin coat over the top to even out the colour?

If not, any other suggestions?

Thanks in advance

 

Or a fine granite mix 3 sharp 1 fine granite chips 1 opc laid wet on a cement slurry.
Needs to be at least 25mm thick.
It will crack in time but will look tidy. Cut out and add expansion joint every 2-3 meters if possible.
Everything will be a bodge as you know.

Used to do this a lot for Peterborough city council to save money replacing old cracked paths and drives, i know lol but it works for a tidy up.
