Render advice

[MattD1]

Morning guys. 
 

I have a small garage that has a sand and cement render which has been painted over. 
 

The render itself is absolutely solid. The paint is flaking in a few places but structurally it’s sound. 
 

I had my house rendered and have some HP12 and silicone thin top coat left over. 
 

My question is could I apply a primer to the existing walls and use the left over base and top coat with some 6mm beads ? 
 

Seems a waste of time knocking the old render off when it’s solid. 
 

Thanks very much

If the render is solid I would leave it.  Just scrape the flaking paint and repaint.

Good advise 

Put the surplus render on market place
