Painted rough cast/wet dash how to recover??

[Jerseyboy]

Hello all
I have a house to price that has been rough casted and painted maybe 5 times
Everything is solid including the paint.
I would normally stipple with sbr then render with sand and cement.
But any better products you could recommend to do the job?
The final coat has to be silicone 1.5 mm
Thanks

Can you build up a thickness of 20mm with parinter
If so do you scratch and leave to cure or Does it go in quick?

Advised to go on 4-5 on painted facade with tv10 mesh in.

Hack it off , unless you want the risk , I never go over paint

By the time I fill the rough cast and get it flat I would be 5 mm then maybe a breeze of 3-4 mm might get me there hopefully
Has it been done before??

It's a 9 inch wall with 20 mm of hard render with rough cast finish.
Basically a bunker it's bullitt proof mate
Would cause more damage trying to take it off

If you think the paint will take the weight , fill your boots mate , just not a job I would or need to take on

The BS standard is no more then 28mm , you going over the original will be far more then that , as said your job your risk

Maybe sand blast the paint off and take it from there that might give me more options
Thanks for the advice

Ok sound will give them a try

Parex spec a maximum of 8 mm so you could bring out mesh in between then fixings at 450 centres when cured then top with 5mm and acrylic.

Tell client if that don't want to hack off that you'll guarantee your work but not substrate ( i.e render)
