how to paint the roughcasted wall?

[LLL]

My house wall is roughcasted. I want to paint it white to make it look better, is that a good idea? How about the stone chips keep falling? The roughcast seems to be deteriorating. If I put my hand on the surface and press a bit, I can see some stones fall.

Spray some normal Delux weathershield paint on it. 

 

You could do it with a brush but it'll take you until the end of time and infinite quantities paint.

Thank you a lot. How about the stones going to drop in the future? will it make the painting off and looks bad as well?
