Browse Forums Building A New House 1 May 30, 2010 9:35 pm We have been told by our builder that we can't have plaster ceilings in our alfresco as they won't be able to cope with the damp conditions. We've seen plenty of photos on the forum with plaster ceilings (which definitely look better) and wonder whether anyone has had any problems. Re: Plaster ceilings to alfresco 3May 31, 2010 9:17 am normal plaster is not good enough. Cement sheeting is better, then you have to consider what paint your going to use. Normal ceiling white is no good either due to moisture. The best product in my opinion is western red ceder. I have used it in my build and reckon it the best thing. So far I have only finish and sealed the area in the porch and it has come up good. Re: Plaster ceilings to alfresco 4May 31, 2010 9:32 am Why would a recessed ceiling in an alfresco have to deal with any more more damp than a ceiling in a bathroom. As long as it is well protected (ie not just extending from the eaves into the alfresco but is within a seperate outdoor room) then you will have no issue. I would use Aquachek plasterboard and seal with an oil based sealer if you are concerned, but plasterboard ceilings in alfresco's are fine. (and they look better than FC sheet) Accessible Carpentry & Cabinets accessiblecarpentry@gmail.com accessiblecarpentry.com.au https://www.facebook.com/pages/Accessible-Carpentry-Cabinets/583314911709039 Re: Plaster ceilings to alfresco 5May 31, 2010 9:41 am chippy Why would a recessed ceiling in an alfresco have to deal with any more more damp than a ceiling in a bathroom. As long as it is well protected (ie not just extending from the eaves into the alfresco but is within a seperate outdoor room) then you will have no issue. That's what we asked but were told it would be exposed to more. Don't really know why though. We are having 600mm eaves around the alfresco and there will be a beam between the eave and alfresco ceiling. chippy (and they look better than FC sheet) Totally agree. Re: Plaster ceilings to alfresco 6May 31, 2010 9:44 am Once the plaster is painted there should not be any issue, that’s not to say that over time moisture won’t have an effect on the plaster, but like chippy said, it’s no different to the ceilings in a bathroom. Unless the plaster is going to get rained on of course. I guess the builder is just covering themselves by wanting to use cement sheeting. Once painted, it should look pretty similar to plaster. The type of paint that gets used is not too much of an issue, normal ceiling paint is ok to use, it will still seal the plaster / cement sheeting as good as any other paint, however, a proper external paint would be better, only because it is designed to handle more extreme conditions and expansion of the surface.

It is a very common practice in WA. My house has one and so do most up market homes unless they have gone for the cedar or timber ceiling. As I said aquacheck and oilbased sealer will deal with any concerns. It also looks nicer to be able to put a nice cornice in. It makes the alfresco seem part of the house rather than a garage.

The question is for how long??? Cement sheet is stronger and while not looking good at the start it will stay like that for much longer. The minimum thing i would do is use villa board. But the butt joins want come up as good. Remember we have not had alfresco for very long. I wonder what the earlier alfresco look like now. What i suspect would happen is that the plaster will start to sag. You will not notice until. it comes really bad. The reason for this is due to cold air on one side and warm air on the other. This is why i have been told by a professional plasterer who has been for many years. Yes this is worse if you dont paint it straight away What make it worse is that many plaster work on 600centre where you probably should be looking at 450centres. Re: Plaster ceilings to alfresco 9May 31, 2010 10:00 am Just looked up CSR webpage. Quite clearly states that aqua check is only for interior use. They have however a noe product which is a combination of Gyprock and Glass fibers to make the product stronger and this can be used outside. Perhaps speak to your builder about this. You should be very happy that he rejected the normal plaster board option at the start because tells that he likes his houses to last that little bit longer. Re: Plaster ceilings to alfresco 10May 31, 2010 10:08 am Aquacheck is typically a wall sheet so yes it is for internal use only. I wouldn't put it on external walls either. But as a ceiling in an alfresco, no problems.

However it all comes up to your expectations. Some people expect house to last 5-10 years. I expect them to last much longer.

Some people expect house to last 5-10 years. I expect them to last much longer. You didn't seem to understand what I was getting at. The CSR site says it is is for internal use only. It says this because some people would read that it has an amount of moisture resistance and may conclude that it would be ok to use it in an external situation (ie external walls or similar) where it would be in direct weather. It is obviously not intended for this hence the warning that it is not intnded for exterior use. In an alfresco as has been described it is not going to receive direct weather it would not be an issue.

Ironic I know. So you will not be able to wet it down to remove spider webs and grime and also you need to remember to be care full if your hose down sliding doors etc in the alfresco. If you dont think you will ever need to wet it down then go for it. Never the less ceder is the premium product in my opinion. Re: Plaster ceilings to alfresco 15May 31, 2010 11:54 am OK, let's put this to bed. I'm a carpenter so have a vested intrest in following correct building standards. I have spoken with CSR and as long as the ceiling has 150mm or more of beams or lintel & brickwork protecting it then Aquacheck IS the product to use. You just need to follow the guidelines for wet areas with the finishes and you will have a product that will last the length of your buildings life. I personally would even be prepared to hose the finished product every now and then (I've even washed regular internal ceilings) as long as it isn't long term exposure. A quick squirt wouldn't even wet through the paint let alone start to be an issue for the product itself. Cedar is nice but for many people it can look a little heavy. If you like the timber look 12mm plywood stained and varnished can also look very nice and is quicker to install. Ultimately it all comes down to personal preference. However if you want a regular flushed and painted ceiling plasterboard is an option.
