Skill, Craft, and Material Understanding

“It’s really the best of both worlds: extremely detailed hands-on guidance to see and feel how the materials behave, and better information than in most books because it’s grounded in real experience.”
— Rebecca, clay plasterer, Australia

Earth plaster is one of the most satisfying, useful, and beautiful skills I’ve ever learned.

It opens up a world of possibilities — from plastering walls and restoring old stonework, to sculptural details, cob ovens, wattle and daub, paints, mosaics, and more. Some people come to this work to build entire houses. Others come because they’re drawn to the material itself — its texture, behaviour, and quiet beauty.

This course supports both.

You’ll learn how earth plaster actually works, not through rigid recipes, but by understanding how clay, sand, fibre, climate, and substrate interact. Once you understand that, you can make good plaster almost anywhere, with the materials around you.


A Practical Course - Grounded in Real Experience

I won’t pretend earth plaster is effortless. At the beginning, it can be frustrating. Mixes fail. Plaster cracks or falls off. And a lot of advice out there simply doesn’t work once you leave the conditions it was written for.

This course exists because of my own experience.

Back in 2011, I was stuck on a remote hill, unable to buy books or materials, with plaster that kept failing, and no clear explanation as to why. What I needed then was not theory, but seeing and feeling what works.

That’s why this course is taught through video, demonstration, and explanation together. It works far better in a digital format than in books.

“I started the course and I think it is guaranteed money well spent.”
— Nick R, Mexico


What You’ll Learn

This is a comprehensive, practical course that takes you from raw materials to finished surfaces.

You’ll learn:

  • How to find and test clay
  • What each ingredient does in a plaster
  • How to design mixes that actually work
  • How to prepare different substrates
  • How to mix, apply, and finish plaster
  • How climate affects your results
  • How to troubleshoot common (and uncommon) failures
  • How to protect, maintain, and finish earth plaster well

There are also additional lessons on:

  • Burnishing
  • Sculpting and mosaics
  • Clay paint
  • Insulating plaster
  • Lime in plaster and lime wash
  • Using earth plaster as a building material (wattle and daub, cob, mud mortar)

This is not a skim. It’s the nuts and bolts explained clearly enough that you can work out why something is going wrong, not just copy instructions.

Who This Course Is For

This course is well suited to:

  • Beginners wanting to learn the craft of earthen plastering from scratch
  • Owner-builders and natural builders plastering real buildings
  • People having problems with existing plaster
  • Creative people working with surface, form, and texture
  • Designers, builders, and craftspeople wanting material literacy
  • People who want to work with the clays on their own land

Some students will plaster entire homes.
Others may never plaster again — but leave with a deep understanding of how earthen walls are made, and how to work with them intelligently.

“Very informative and good instructions in the text and videos!”
— Nanda Doornik, Ireland



Who This Course Is Not For

  • Experienced professional plasterers who already work fluently with earth
  • People looking mainly for theory, history, or academic discussion
  • Anyone wanting shortcuts or rigid formulas without understanding the material

This is a practical course for people who want to actually understand and work with earth — thoughtfully.

Atulya K Bingham

Hi! I'm Atulya. I've lived off-grid and built with mud for over ten years. My love of natural building arose from nowhere. Back in 2011 I was living in a field in Turkey. Bit by bit, out of necessity I taught myself to build with mud. It became a creative passion. Within a year I had constructed a house. A year later I installed solar power. I have been in nature, mud building and writing about it ever since.

Today I am founder and author of The Mud Home natural building and off-grid freedom website. I also write about natural building for publications such as Mother Earth News and the Owner Builder Magazine.

I'd love to have a go at plastering but don't have a house.
This course was designed for pretty much any location. It's actually a super idea to learn this skill before you have a house! You will save yourself a lot of time and trouble in the long. And you can use earth plaster for so many other things: Sculptures, cob ovens, pet homes, and more. The course gives instructions on how to make a plaster board if you don't have a wall. You can do the practicals in your garden, in a small back yard. Even on a balcony.
I'm having trouble with my earth plaster. Will this help me?
It is awful when your plaster fails (ask me how I know). An entire section of the course is devoted to understanding what makes plaster tick, and why it can go wrong. By the end you should understand how to get plaster right in pretty much any climate, with various soils and on different surfaces. If not, feel free to ask for your money back.
Is the course all theory?
Not at all! There are easy practical assignments at the end of each section that you can do pretty much anywhere.
Can I download the material?
The course has especially been designed with off-gridders and limited internet in mind, so everything can be downloaded for reference and later study.
Is this course going to teach me how to build a house?
No, this isn't a house building course. It's all about mixing, applying and protecting earth plaster.
Where can I get support?
If you need help or you're having trouble with the course, write to atulyakbingham@themudhome.com . Although I usually respond within a day, because I'm off-grid and time zones vary, it may take up to 48 hours. Please check your spam folder if you can't see my email, I always reply!
