The wait is OVER! The Medina project is finally ready to be shown off! 😎

This project has been a HUGE milestone for Del Toro Natural Builders as it’s our first project where we’ve completed the interior clay plaster, exterior lime plaster, AND adobe floor finishes

Let’s start with the interior!
The walls are infilled with hempcrete, which is an incredible natural building material with great moisture regulating/insulation/sound dampening properties and is also non combustible and mold/pest resistant! But what makes these walls even more special is what we finished them with!

We started by applying base coats of clay plaster made from clay that was actually harvested and processed right there on the property! That clay was then mixed with locally manufactured limestone sand, commonly referred to as “man sand,” to create our base plaster.

Once the base coats were complete, we applied my very own clay plaster finish made with recycled glass sand!

That’s right, RECYCLED GLASS! 🤯

Not only are we utilizing materials that would otherwise potentially end up in a landfill, but we’re also creating a beautiful, durable, breathable finish that works WITH the hempcrete rather than against it.

One of the greatest benefits of natural wall systems like these is their ability to help regulate indoor humidity by absorbing and releasing moisture v***r as well as being a thermal mass. Pair that with hempcrete’s insulation properties, and you’ve got a wall system designed to contribute to a much more comfortable/controlled indoor environment!

Now let’s talk about these ADOBE FLOORS!

Roughly 1,200 square feet of beautiful, handcrafted earthen flooring!

These floors are something you really have to experience firsthand to fully appreciate.

Unlike conventional concrete floors, properly finished adobe floors have a unique warmth and feel to them. The best way I can describe it is like walking on LEATHER!

They’re smooth, comfortable to stand on, and have an organic feel that’s hard to replicate with conventional flooring materials. While they’re still firm surfaces, there’s something about walking barefoot on an earthen floor that just feels right!

And the amount of work that goes into creating them is no joke! From placing and leveling thousands upon thousands of pounds of earthen material to applying the oil, every step requires patience, craftsmanship, and a whole lot of physical labor.

But here’s what I find most fascinating about this entire project…

We’re taking materials that come naturally from the EARTH and turning them into the finished surfaces of a HOME!

Clay from the property, locally sourced limestone sand, recycled glass, and natural earthen materials.

No conventional petrochemical-based plaster or flooring finishes. No need to cover these beautiful natural materials with synthetic coatings.

Just good old-fashioned building techniques combined with modern knowledge and a whole lot of hard work!

There’s something special about being inside a home finished with natural materials. Between the moisture regulating properties of the clay, the insulating/sound dampening characteristics of the hempcrete, and the earthy feel of the adobe floors, the whole space just feels inviting and what a home is supposed to feel like.

It’s like bringing the outdoors INSIDE! 🌎

And that’s what natural building is all about to me. Creating beautiful, non toxic spaces using materials that have been around for thousands of years while incorporating sustainable practices and materials that make sense for the future of the home dwellers and the earth.

I’m incredibly proud of how this project turned out, and even more grateful for the opportunity to bring it to life.

There’s SO MUCH more that went into this project than what I can fit into one post. If you guys are interested, I’ll put together some posts about the base coats of clay and what it took to get them done.

And we’re not done showing this one off just yet!

Next up is the EXTERIOR, where I’ll be showing off our traditional three coat lime plaster system over hempcrete, including the preparation, scratch coat, brown coat, veneer coat and limewash finishes!

So stay tuned! 😎

Applying a scratch coat of lime plaster over CEBs that have already received 3 coats of limewash. The limewash helps stabilize the loose sand and dust on the surface of the blocks while also acting as a primer for the plaster system. We also mechanically attached FibaLath to the substrate for some extra reassurance and to give the lime plaster a solid mechanical bond. Just another step in making sure this wall system is built to last.

This video shows a little bit of what goes into the job, pushing loads of lime plaster up the hill to where I’m working and slinging some mud, but it doesn’t come close to showing everything that happens behind the scenes.

There’s mixing the plaster, spraying and prepping the walls, setting up workstations, moving everything as the job progresses, hauling materials, cleaning up, and then doing it all over again. I’ve been pushing about 8–12 of these loads up that hill every day this week, and I’m exhausted.

The lime plaster system is being applied over lime-washed CEBs (Compressed Earth Blocks), with FibaLath installed to help reinforce and provide a solid substrate for the plaster system. A lot of work goes into these walls before you ever see the finished product.

But as tired as I am, this is exactly what I prayed for, and I’m beyond blessed to be doing it. Being able to provide for my family is a huge part of why I work as hard as I do, and why I can’t stop.

What can I say… I’m addicted to the shindig. 🤘😂

So why are we lime washing these CEBs (Compressed Earth Blocks)?

The answer is that the surface is extremely dusty and sandy.

So why is the surface so dusty and sandy?

Long story short (well… I attempted to make it short, but it’s not 😂), the person making the blocks was supposed to stabilize them with lime. Unfortunately, he underbid the job and tried to save money by skimping on the lime, which resulted in non-stabilized blocks. On top of that, the blocks were made with too much water.

Now take those misfortunes and add masons with no experience in historic/natural wall systems installing them, while also mixing the mortar with far too much water and not enough clay or lime. Ultimately, what you end up with is a less-than-desirable substrate that is highly susceptible to water.

With this being the case, the homeowners attempted to protect the walls by applying a clay/lime scratch coat of plaster. However, with the weather conditions over the last 6–7 months, that attempt simply wasn’t enough. The result was catastrophic failure and the complete removal of the plaster, leaving behind the dusty, sandy surface you see today.

This is why we’re lime washing the walls to stabilize the surface of the blocks, mitigate the dust, create a better bond for the plaster, and help make both the blocks and the mortar less susceptible to water damage. We can now spray the wall with water and watch it run down the surface without washing it away, which is a huge victory.

After the lime wash, casing bead and Fibalath are mechanically attached to the wall using galvanized 1-inch crown, 1½-inch leg staples, along with Tapcons and galvanized washers. This way, the plaster doesn’t have to rely solely on its bond to the lime wash and the blocks to stay attached. I’ll be posting pictures of that process next week.

Pictures of the Medina project including the interior clay plasters with earthen floors and the exterior three-coat hydraulic lime plaster system will be posted at the end of August to allow them time to finish the exterior grading and patio work.

Thank you to everyone who follows and supports me through this journey. And to all of my fellow historic and natural builders in the community, keep it up! If none of us give up or give in, we won’t just change the way people build or the environments they live in. We’ll change a culture and a mindset… and that has the potential to change the world. 🌎💪

Since it’s been a while since our last post, here’s a sneak peek at the Medina project.

The rich brownish-purple earthen floors dive into stunning limestone, while a hand-crafted flower and butterfly clay plaster detail adds a nice touch in the background. We’re currently putting the finishing touches on the exterior lime plaster, and once that’s complete, we’ll be sharing a full reveal of the home inside and out.

This project marks a big milestone for DDTNB, as our first build featuring both full interior and exterior plaster work alongside custom earthen floors. Stay tuned!
