External plaster in winter???

[newname]

Hi

Is it a bad idea to plaster the outside of the house in winter? Does it dry properly or run and look streaky or anything?

Our house is being plastered at the moment in between the rainy days.
Plastering can only be done on a dry day ( even in winter ) otherwise the rain would wash it away.

i though you couldn't plaster if frost was expected as it would ruin the finish, if it freezes that plaster won't set right as the water in the plaster mix freezes, expands and then contracts when the frost liftd..open to correction..

Exactly johnnyg. The plaster will crumble as the frost has stopped the initial set. If this happens to the scud coat, then the scratch will pull away and if it happens to the scratch the rub-up coat will pull away. Then after a few months it looks like a spider's web of cracks and the wall will sound hollow. Penetrative rain will finish off the debacle.

I would leave the plastering untill spring time but the off shoots on the house aren't slated yet. Is there any way of going ahead and finishing the slates and then covering and protecting them adequately from damage when the plasterer arrives???

could you not try and plaster those sections now, so that you can slate the offshoots, its not winter yet, it is getting colder but not freezing and the weather is dryer, so still can do it..
