What Happens When You Use Frozen Lime Putty in Lime Plaster?

This fall I started a little home improvement project on the Timberframe building at Dancing Rabbit Ecovillage. The house had originally been plastered with earthen plaster on strawbale and lime plaster on top of the earthen plaster. This didn’t work so well and over the years the lime plaster has been cracking and peeling off the undercoat. I’d planned to buy all new lime for the project but then I found a barrel full of old slaked lime putty. This had been left out for many years and experience freezing and thawing many times.

I wondered, can you still use frozen lime putty? People around Dancing Rabbit had always spread the rumor that frozen lime putty was no good because it’s chemical structure had changed through the freezing. But I looked it up online and found that that isn’t true. So I decided to make use of that lime putty and redo part of the wall with it. How did it turn out? Watch the video.

  1. Thanks for clarifying use of frozen lime putty. I had heard that it was not good to do so as well but not convinced. Thanks for demonstrating its use as well. Looks good
