The essential guide to lime. Plasters, paints and cretes, with Aulya Bingham from "The Mud Home"
I’ve talked about many different building materials through this series, but one of my all time favorites often gets overlooked because it isn’t commonly used as a structural element. Lime in all of its various forms as a plaster, paint, mortar, grout, poured floor or even in newer applications like hempcrete, has so many advantages and applications in just about any style of natural or conventional building. That’s why I reached out to the “Mud Witch” Atulya Bingham, who’s been interviewed twice on this podcast before because she just released a new online course covering everything you need to know about this incredible natural material.
In this interview we cover the lime cycle and the various products that can be made or bought from the original limestone. We talk about different additives to make all kinds of plasters, paints, mortars and more. Atulya shares a lot of experiences of her own in working with lime as she builds her new off grid homestead in northern spain and why it’s an ideal material for damp and humid places. We also compare and contrast lime to other alternative materials as well as its limitations and compromises too. This is one of the materials that I’ve seen people struggle with the most and that I’ve noticed that many people avoid because it can be made to seem that it’s more dangerous or complicated than it is. There are very few resources out there that simplify the use of lime to the layperson or amateur builder which is why I was so glad to cover this in a way that hopefully demystifies the practical use of lime for so many great applications.
