YES. There are many products on the market, one of which is SBR mixed with OPC cement. This creates a slurry which is applied using a brush. I then allow 24 hours for it to dry and then i apply a second coat but follow it straight up with a sand cement scratch coat whilst the slurry is tacky. Following this i render as normal.
When regarding taking of the render, this is a very difficult and expensive job.
Working out the price is easy. Simply ask an experienced plasterer to give you a quote.
As far as having the whole house rendered, i would advise having it done in-between april and august. I would also warn you that there could be some cracking. This happens on new builds let alone a property that has been re-rendered.
Hope this has been of help, Gordon (G S Thompson Construction)

you need to have the paint taken off 1 option is a electric scrubber - http://www.hss.com/g/5241/Textured-Surface-Remover.html
but the amount of time it takes doing this and to do a job well its best to take back to brick especialy if its to thick in places. you can buy a sds lockable hammer drill that acts as a breaker put googles on and ear plugs and chissel away.
hope this helps, if so click like

If the render is blown hack it off if its hold leave it and just do patches lo level.
Whole render paint with a proper chemical which will get in to render and make it stronger,then fix 20mm polystyrene boards over existing render,fit fibre glass mesh in to adhesive prime it and finished with modern coloured silicone render.System is anti crack,waterproof,self washable longer colour life when its rain and cheaper than remove render and redone and paint every 5years.experienced company charge from £45per m2 plus scaffold
