The Perfect Earth Plaster Course

Learn how to master beautiful plaster in 11 Lessons

"I'm really enjoying your earth plaster course! I particularly loved it when you gouged into your wall and replastered so confidently. Brilliant!" Kim Fraser, The Hideaway Under the Stars.

Perfect Earth Plaster, and More!
Earth plaster is one of the most satisfying, useful and beautiful things I've ever learned to master. It costs next to nothing to create, and opens up a world of construction, artistic and decorative opportunities. Once you get the hang of this art, you can not only render houses, but restore ancient stone work, make earthen structures like cob ovens and chicken coops, create paints, sculpt reliefs, make wall mosaics, wattle and daub, and more. Your imagination is the limit.

I'm not going to lie though. Earth plaster can be tricky at the outset if you don't know what you're doing. Recipes often don't work because earth plaster is notoriously dependent on local climate, soil make up, and the surface you want to render.

"I started the course and I think it is guaranteed money well spent, thanks so much!" Nick R in Mexico.

Do you want to create a beautiful clay plaster from the clays around you? One thing Iā€™m proud of in this course is that it will show you how to forage for your own clays in your surroundings, and create beautiful plaster from the dirt beneath your feet, rather than just relying on shop bought products. This Perfect Earth Plaster Course will teach you step by step how to make plaster just about anywhere, and very inexpensively. It empowers you by giving you the tools and understanding to eventually become a plaster master yourself, with some practice. In this course, I share with you my personal techniques and discoveries too.

"Very informative and good instructions in the text and videos! Absolutely helpful, thanks for putting it together." Nanda Doornik, cob oven builder in Ireland.

"We definitely found this course helpful when we plastered our sandbag wall." Luke and Kath in New Zealand.

One of the reasons for this online earth plaster course was my own experience. Back in 2011 I was stuck on a remote hill unable to buy books on earth plastering. My plaster was failing me, and I couldn't understand why. What I wouldn't have given for a decent online course!

Now I see: Teaching earth plaster works far better in a digital context than in book format. Videos are crucial for seeing exactly how plaster is mixed and applied.

Who is The Perfect Earth Plaster Course for?

1. Beginners: This course is perfect for those wanting to try their hand at plaster for the first time and play. It takes you through the entire plaster process from finding materials to maintenance.

3. People having issues with their earth plaster. Oh I've been there! And that is why I've devoted an entire section to solving what is going wrong with your plaster.This course is not a surface skim. It gives you the nuts and bolts of plastering to help you work out why your plaster is failing, and what to do about it.

4. Creative people wanting to make beautiful things. This course will unleash a world of creative and artistic possibilities in you, many I haven't even thought of no doubt. Mosaic, sculpture, interior design, and more.

5. People who want to try and use the clays on their land. One of things I'm proud of in this course is that it will teach you how to find your own clays, test them, and build without buying in lots of ingredients.

This entire painted wall sculpture was created from clays I found on my land.

Who is The Perfect Earth Plaster Course NOT for?

Earth plaster experts and professional plasterers. If you are already an expert, this course is not going to meet your needs.

People who want to theorise and geek out on lots of extraneous details, or who want the whole history of clay plaster. This isn't for you. This is a simple practical course for people who actually want to plaster.

It will take you through the testing process, mixing and application. Each of these stages include details which when missed can cause issues with your plaster. (See the curriculum below)

The course will also show how to make your plaster water resistant, how to protect it and maintain it. There are extra educational videos on burnishing, how to make a plaster board, how to use a trowel for beginners, and more.

Here's a list of what's covered in the course:

  • How to find clay for free (it's all over the place).
  • Understanding which ingredient does what in your plaster.
  • How to mix your plaster; tricks and tips.
  • Testing your plaster and understanding the results.

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.
