Renewing or replacing pebble dash?

[a-m]

We would like to sell our Edwardian house but the marketing photo showed up lines on the front of the house where I used lime when filling in historic settlement cracks, 2 under and 1 over a window. These came out lighter than the surrounding pebbledash. We are concerned that this may put potential buyers off and so we are considering our options. The pebble dash seems sound (not blown) and a honey colour which suits the house/period. Can we brush off the loose stuff, leave the existing render intact and use as base coat and then apply sloppy render and pea gravel? It seems a shame and would be time consuming to hack off reasonable render if this is not necessary. Or would it be necessary to remove the existing render/dash? I would prefer not to paint the pebbledash.

I'm sorry I can't give you other options a-m.
Just to say.....please don't try pebble dashing it yourself. It's a hell of a job even for a Pro. The backing coat has to be just right - and the gravel has to be continually washed and washed and washed etc while "throwing" it - or the result will be such a mess, you'll have to paint it :o(((

Thanks, The Builder. We're leaving the original as base coat and getting in a pro.
