skim external porch walls - what to use

[pjsmith]

Hi,

I've gotten OK at skimming the internal walls with multifinish but now want to skim over the 2 small porch sides that are semi covered (sort of an innie-outie porch) as they've accumilated a lot of bumps over the last 70 years. Pretty sure I can't use MF for this due to the fact it can get rained on, but can't see what to use. On a trip to B&Q I could only find 1 ready mixed pot of somthing that looked suitable for exterior use, but not sure of the finish it gives and it said it cannot be used under 10 degrees C which is obviously an issue right now.

Any suggestions?

Thanks.

It's a 2 floor house. The front door is set back into the halway in the centre front of the house about 1M so you have a covered area (by the first floor), but with wind blowing into the porch it does get wet with driving rain.

I'm only looking to put a couple mm over the sides to fill the dents and smooth it all over. Can I do that with just sand and cement like I do with multi finish and just sponge it after?

if its multi that youve got on there already then not really im afraid.
you could skim over and paint it with a good bathroom paint one thats designed to be able to cope with a bit of water.
if you can plaster to a decent standard this might be the easier option to take.
would it not make sense to put anouther front door onto protect it a bit.
just a thought.

No MF on their already. Not sure what it is under the paint, but it's not MF. I guess it's a cement render. Really I was hoping to get a similar product to multi finish I could skim a thin coat on as I'm fairly sure I can get a good finish like that. It just needs to be suitable for exterior use.
