Re: Quicklime vs. portland cement plaster
Hi Ken,
Thanks for sharing your knowledge on this one. (Ken is a pro, Italian-trained Venetian plasterer). This is very helpful and it all is starting to make a little more sense. One of the Italian plaster makers claims to age N type lime in a cave for one year before using it. I haven't quite figured out why aged lime putty is better, but I am getting there. I can see why you would never mix your own at home.
I have also read that portland-based plasters can be more difficult to work with (fast setting and hardening), and that you cannot apply it over gypsum compound on drywall -- you need fresh green board. Is that right?
Looking forward to my trial plaster. Also, the color-in samples were from Texston -- the colors and finish are very nice.
