hey question to throw out there. potential client looking to use Mantovano in bathroom, however there is a steam shower in room and the finish will come pretty close to it. Would you go with the lime, or use veneziano over prontomuro?? open to all thoughts, project to start in 2 weeks, would like ideas early than that if possible. Thanks in advance and hope you are all having a wonderful day- I am.
the gut instict is use VP. However, I have used lime paints in bathrooms with soloxane glazes and never had an issue. I can't see how this ould be an issue either...AS long as it is just steam and not water splashing on it, you ought to be able to have success.
Graham, good question. I will tell you my experience with this. The synthetic (veneziano) montovano would be a better choice in my opinion. I have subjected some of my lime based samples to water exposure via spritzing. This was done to Calcenova and to Fresconovo over prontomuro, 3 coats each properly applied and burnished sufficiently. I spritzed it because in a steam shower situation moisture will build up on the walls and it will run, this is assured. So don't think that this is not an issue it certainly is. Of course the lime plaster breathes but I have found that on the lime samples I spritzed, water did stain the surface when it runs....even after it dries out, perhaps this could be partly attributed to the treated, clorinated water that comes out of showers and faucets (if there is no water purifier presently attached to the head). These were samples that I let cure for months too before trying this. I also recommend letting the venzi cure at least a few weeks before advising any showers...this is a safeguard, the longer it can cure the better. Sorry if I am busting anyone's bubble with this but this has been my experience. Spritz some of your lime and mantovano boards and let the water run. See what happens for you once they've dried.
I have a bathroom project coming up that will likely be a veneziano finish. I am highly recommending that my client install a special filter to the head. THis will help with some of the chemicals that are in the water that become airborn through the steam. I also am recommending 2-3 weeks of cure time before any showers ensue. Good luck with it Graham

thank you for input,really appreciated. I spoke with homeowner today and he said I can meet builder this week sometime. The bathroom I am talking about is top floor of A-frame house approx. 150 sq ft. also looking to do metalo finish around 6x6 sink wall, with verde. Thanks for the shower head idea, makes sense to recommend that...but still seem confused on 2-3 weeks cure time for venzi....can you eleaborate. application would not be in shower, but on bathroom walls, however high degree of probability to get direct water and steam contact. further, is there preferrable sheetrock to hang, or hardybacker? I know I sound rook, but alas I am, but do love the spirituality of what it is I am doing and trying to do. And again, thank you all, I get so much out of this site, love the community of it, and am grateful to SOIP for opening my eyes. Much love
Graham, I'm glad we are able to help. I understood from the beginning that the veneziano would not be going directly in the shower and my advice reflected that. The longer cure time is recommended as your safety net. You don't want to tell someone 'oh, just wait a few days or a week at the most' because in fact it is difficult to state exactly how long it will take the venzi to cure. It is better to overshoot that length of time than to undercut it just so your clients can start taking showers. THe application is too expensive to make that compromise. It is better to weigh on the safe side. If these clients take warm to hot showers for more than 5 minutes and up at a time, steam will be genereated and it will build up on the walls and that condensation will run, as drips. It is a gurantee. If they don't take showers at all, then there is no worries. Is that clear? You asked about the sheetrock, regular sheetrock is fine, the substrate doesn't need be concrete board, unless it is in the shower directly. It is imperative that the joints of the sheetrock are taped/mudded and sanded smooth as you will see the joints telescope through in the end of your venzi application if they don't do their job correctly, so it is a good idea to emphasize this to the builder.
As for the metallo, Safra does not rate its application for wet areas, although you may be able to seal it but you will lose some of the natural beauty of the plaster in doing so.

p.s. Graham, it wouldn't be a bad idea to post a question to the lab concerning the curing times in a wet area.

much appreciated greg...and I think I will post to the lab as far as cure times. as soon as I can figure out how to load pics, I will post the two Calcenova walls I have completed for critique. As always, the value of these threads are indispensable, and the care and time of those who share.....well thanks, truely.
Hey Greg, Lets say the client is set on a Metallo finish for a bath room area and if you did use a sealer or a wax what would YOU use? We have a very large project coming up and there is a master bath in a Metallo finish. I'm looking forward to your input. Ken.
Ken, This wouldn't be a bad question to post to the lab either, but it seems feasible to use perhaps aquarello finisher (troweled on) or a water based sealer....maybe even using two different sheens of a sealer applied at once in a fashion that will display a multi-tude of sheen in the end. That might preserve a small percent of the variation in the light reflection on the Metallo. Other than that, I've seen some applicators putting Liberon over the Metallo, but I'm not particularly fond of using wax in moist areas....eventually re-waxing will likely be desired.
