Would it be ok to plaster outside walls?

Question

The wall will not be touched by rain water but would be open to the change in Temp (changing of the seasons) If this is not a good idea what would you recommend?

The area is a 3 wall seated area with a roof.

Answer 1

render and pebble dash , or render only , or render and Tyrolean finish ( render with sand and cement ) , clad with timber or plastic cladding , paint with masonry paint , I suspect plaster would perish if air borne moisture can reach the wall . Dont forget the inside of the wall needs to breath too so bear that in mind ,  moisture can reach the wall as airborne moisture and condense onto the wall .

Answer 2

Do you mean stucco?  Plaster isn't waterproof.

Answer 3

get someone in to render it, its a skilled job and most likely failures in bonding if you do it yerself.  

Answer 4

The plaster would be effected by the humidity. A better be would be to use a stucco product. It should give you the same effect without worry about being outdoors.

Answer 5

Put a bonding agent on first and plaster away.
