Lime Plaster Workshop Oregon City, OR

It is if…

• You don’t want to be the person who slaps mud on the wall and says, “good enough,” only to watch it crumble off a week later.

• You’ve helped stack bales or plan to, but now you want to understand what it takes to finish them right with durable lime plaster.

• You’ve done plenty of construction, but you know plastering is its own animal, and you want to learn from people who have already made the mistakes.

• You’re planning to plaster your own home and would rather practice on someone else’s first.

• You love the idea of spending three focused days working hard, learning useful skills, and laughing with a crew of like-minded folks.

• You appreciate good food, good company, and the satisfaction of watching raw walls transform into a finished surface you helped create.

Over three days, we’ll dive into the full process of applying natural hydraulic lime plaster to straw bale walls. You’ll learn what makes lime unique, including how it transforms through the lime cycle and why it performs so well on straw. We’ll go over setting up a proper mixing station, cover mix recipes, and review aggregates and their roles in strength, texture, and finish.

You’ll get hands-on time mixing and applying the brown coat, learning efficient body mechanics for long days of plastering. We’ll focus on troweling and floating techniques to achieve an even, well-bonded coat ready for finish. We’ll also touch on color coat basics, how to prepare for it, and what to consider for future maintenance.

By the end, you’ll understand how to mix, move, and apply lime plaster confidently and with care—skills you can take home to your own project.

You’ll be learning directly with Timbo, who has over twenty years of experience in straw bale design and building, and a particular love for plaster. Timbo believes plastering is where the house comes to life. He’ll be right there beside you, showing how to mix, apply, and shape each coat with care and confidence. Expect clear instruction, steady guidance, and plenty of hands-on learning.

Tuition and Deposits are nonrefundable. Because organizing these events is a significant undertaking with many moving pieces, and planning, and involves many people, over months and often years, we maintain this policy. 

That said, if you are unable to attend the workshop location and date that you originally selected, we will gladly work with you to transfer, or credit, your tuition towards a future workshop (assuming there is a future workshop.)  You must contact us before the start date of your initially scheduled workshop purchase for this credit to be issued. Your tuition credit would be valid for one (1) year from the start date of your original workshop. Alternatively, you can transfer your tuition to another person to attend in your place if that is your preference.

What happens if the workshop is canceled? This is something that we work hard to avoid and is rare in the overall schedule of events. That said, because there are elements of the workshop that are outside of our control (acts of God, COVID, etc.), there is always a slight chance that it could happen. If it were to occur, we would offer you the following options to choose from:

1. Switch your tuition to another workshop location in the current year’s schedule. 
2. Transfer, or credit, your tuition to a location in the following year’s schedule.
3. Receive a full refund for your tuition. Cancellation of a workshop is the only situation in which the non-refundable tuition becomes refundable.

*You can register with a Deposit-Only payment to hold your spot in the workshop. Your remaining balance is due 30 days before your workshop start date.

Deposit payments are non-refundable, just like Pay-in-Full registration payments. See Purchase Details for more information.

On-site tent/car camping site is provided and some workshops have room for RVs as well (email us at info@strawbale.com asap if you need RV space so we are sure to set a spot aside for you!) Host-provided meals are hearty, delicious fuel and we often hear feedback that the meals are a highlight for folks. Showers are typically privacy screened outdoor-style with on-demand heaters and/or indoor. Hosts always do an amazing job of making participants feel welcome and cared for!

One person, or Participant, per registration please.

A Participant is an individual who joins the workshops' learning activities, including lectures, evening talks, and hands-on skills.

Due to capacity and safety reasons, we must limit the number of Participant spots.

Please ensure the number of registrations in your Cart exactly matches the number of Participants you are registering.

The days are full and long. We will start each morning with breakfast at 8 am and we begin Q&A/Lecture/hands-on work at 9 am. We break for a leisurely lunch around 1 pm, our afternoons continue the hard work of the morning, and end the work day by 6 pm.

Dinner is usually around 7 pm. We usually eat pretty close to that time, but some flexibility is appreciated. Our dinner and evening break is full of fun and play.

Although physical work is involved in building the structure, participants are encouraged to work at their own pace. You know your limits, and those limits are respected.

Our goal is to get as far as possible in the construction of the building, from setting bales to plastering. In most cases, we will not get beyond the scratch (first) coat of plaster.

Folks hang out to be social, grab showers, or relax between the end of the workshop day and dinner. When fire restrictions allow, we have campfires and we encourage folks to bring their instruments and willingness to play together for the friendly group!

You’re welcome to arrive the day before the start of the workshop to get set up; anytime after 2 pm is ok. We’ll finish up no later than 4 pm on the final day of the workshop to help with travel. Once again, you’re welcome to stay for another night if that makes your travel plans easier.

It is truly unique to be learning on an active construction site (Thank you Hosts!), and we embrace that as instructors. You’ll see us model transparency around decision-making, the common change-orders of home construction, working around subs, etc. We are open books, because we want YOU to experience what really IS to best prepare you for your own projects!

Feel free to bring whatever other tools you would like than what is listed below. If you have something you think would be useful, you’re welcome to bring it. We understand how nice it can be to use tools you are familiar with or want to learn more about!

Camping is available on-site for free, and bathroom facilities are provided, including showers. We ask that showers be kept to a minimum in both duration and frequency to save water and to make sure that every participant has the opportunity to enjoy a hot shower. Usually the showers are an outdoor style with privacy and a changing stall per shower included.

Some workshop locations may have other accommodations available, such as cabins or tipis. Those accommodations are issued on a first-come, first-served basis and may or may not cost extra based on the workshop host/site.

There may also be room for RVs at some workshop locations!

In most cases, we can accommodate serious food restrictions, such as, gluten-free, lactose intolerance, peanut allergy, vegetarian, etc. (To be kind to the Hosts, who always pour their heart into providing delicious, nourishing meals, please note that this doesn’t mean things like: “I don’t like Brussel Sprouts.”)

Be sure to let us know ASAP any requirements you have so we can see what’s possible. We cannot guarantee that we will be able to accommodate every need, but we will do our best to do so. Email Dainella at info@strawbale.com with questions. :)

Airline tickets are often less expensive the earlier you buy them, so we understand the desire to buy early. That said, we recommend that people buy their tickets no earlier than 30 days prior to the start of the workshop.

At this time we will connect everyone in the group together in an email and with a group survey to help coordinate ride-sharing. Often, folks will also be open to sharing off-site accommodations with others who don’t wish to camp or are flying in. If you have questions, feel free to email Dainella at info@strawbale.com for a chat.

You are most welcome to arrive after 2pm the afternoon of the day before the workshop and stay over on the last night after the class ends if that helps your travel plans.

You are welcome to stay on-site or at a hotel. It’s up to you. It is always a mix at every workshop!

In most cases, that’s fine. We ask that non-participating Guests pay for their food: $85 for 15+ years old and $65 for 14 and under.

In some cases, there will not be enough space in the Group Meals, or on-site, as the hosts sometimes “max out” in terms of food preparation numbers or site facilities, so please ask us asap. The earlier we know, the more likely we are to help accommodate guest requests.

Kids are welcome to join us as Guests or Participants, depending on their age. We require that the parents/guardians take full responsibility for the kids and their safety.

Contact Timbo at info@strawbale.com to coordinate so we can help ensure the best experience for them.

Keep in mind that it is an active construction site and, therefore, inherently dangerous. We trust parents/guardians will make the choice appropriate for their kids.

Kids under 12 cannot be left unattended, so a non-participating adult must accompany them. If you plan to bring your children, please contact us in advance to work out the arrangements.

When kids come as non-participating guests that are joining in group meals, but not participating in the workshop learning and activities, we ask that the parents/guardians pay for their food so that it’s not an extra financial burden for the hosts. The fee is forwarded 100% to the hosts. The costs are $65 for up to 14 years old and younger and $80 for 15+.

Supervising adults not attending as paid Workshop Participants will also be charged the 15+ food contribution of $80.

If the kids will be participating in the workshop, then they would pay a normal registration fee which already includes meals.

Guests and Supervising Adults/Guardians must sign a waiver and agreement to be present on the property during the workshop.

Tuition is nonrefundable. Because organizing these events is a significant undertaking with many moving pieces, and planning, and involves many people, over months and often years, we maintain this policy. 

That said, if you are unable to attend the workshop location and date that you originally selected, we will gladly work with you to transfer, or credit, your tuition towards a future workshop (assuming there is a future workshop.)  You must contact us before the start date of your initially scheduled workshop purchase for this credit to be issued. Your tuition credit would be valid for one (1) year from the start date of your original workshop.

Alternatively, you can transfer your tuition to another person to attend in your place if that is your preference.

Absolutely. The level of work performed on the site is entirely up to you. We have had people come and limit their physical work to sweeping up the job site and tidying up. That plays a critical safety role in the workshop and is more helpful than you might imagine! They learned a ton and had a great time.

Every workshop is different, but the goal is always to have a large enough class to allow people to work at a reasonable pace and be safe.

We want you to have fun, learn, take notes, ask questions, move around to a variety of tasks to learn skills, and feel like you can take a break when necessary.

To give you an idea, technically “full” varies per workshop from 10 to 20 and depends on the size of the project and terrain for safety reasons.

Again, it’s not about keeping you flat-out busy the whole time. It’s about allowing you to learn at your pace and have fun all week while still contributing work to create a beautiful home for the workshop host — who has welcomed us all to the rare experience of learning on an active, no-artiface job site!

This is something that we work hard to avoid and is rare in the overall schedule of events. That said, because there are elements of the workshop that are outside of our control (acts of God, COVID, etc.), there is always a slight chance that it could happen. If it were to occur, we would offer you the following options to choose from:

1. Switch your tuition to another workshop location in the current year’s schedule. 
2. Transfer, or credit, your tuition to a location in the following year’s schedule.
3. Receive a full refund for your tuition. Cancellation of a workshop is the only situation in which the non-refundable tuition becomes refundable.

As much as we love dogs... To be fair to the Host’s neighbors with dogs who might get overly excited about visitors, we ask that you leave your furry friends at home. If you have a therapy dog, please reach out to us at info@strawbale.com.
