Is there a nice outdoor, weatherproof paint that can be used to create a textured stone effect?

Question

I know you can buy this engineered styrofoam and apply it to the outside of your plywood frame of your house, but is their a type of paint that you can spray on to give a nice textured rock appearance? Its an outdoor retaining wall that is basically made from plywood. It doesn't look terrible now, but I'd definitely like to make it look more professional.

Answer 1

Hi try searching for flex-rock or stone effects--both are brands of granite like rock that comes in a spreadable paint form.

You have to buy the primer usually & the product & then an epoxy finish--but you can purchase both brands in MANY colors.

The company that makes it is called Beauitone.  

Answer 2

Try Sandtex, its a sand textured external emulsion paint, not sure what effect you are hoping to get but thats all I can think off.
