This is my treatise to wall treatments!! It's been 15 glorious years as an earth-plaster professional.
Hands, fingernails, and pant legs....caked and crazed with all sorts of pigments and aggregates. Wear and artifact from the layers of my steel hawk mirror...tall ceilings, narrow planks over stairwells, dead tired moments, and tales of great victories!
Over this time I have applied the earth. Clay, lime, marble, and sand have all spoken to me as the materials I respond to with creative intensity. My senses are delighted. I will admit my bias. I love things from the earth. AcryliCKS and plastic stencils have no place in my palette.

When I receive a new client inquiry, how do I determine the right earth plasters to use? Creative bias + knowing material properties is the formula for successfully specifying the "right finish for the right space." It's important to know the differences between finishes whether you are a DIYer, interior designer, or architect. Before you pick up the trowel, consider these factors:
Damage will happen regardless of material.
Identify high-traffic areas and design accordingly. Wood, metal, or stone/ceramic tile have much higher impact resistance (psi) than common wall finishes so design a wainscott height (4'+) wall treatment and plaster above it. Also, if you are in the "space planning" stage, consider designing larger corridors or openings to allow for better traffic flow.

Repairability? Wearability?
Softer materials like clay are easier to apply and repair than lime-based materials. For an unsealed clay wall, you infill "ding" with product, let set then blend out with water. This is great news for the DIYers since you can easily and quickly fix your own walls. No toxic peel spray either! Clay is easy to apply and a great way to begin your creative journey.

But what about repairing clay with a large commercial space? It can be a "punchlist" nightmare. For heavier-use projects, go with a harder lime-based material. Lime has a higher psi (pounds per square inch) than clay. A stronger surface overall will not dent or ding as much as a softer one, so your maintainence costs will be less. Interestingly, lime plaster derives itself from limestone, so this plaster is essentially a stone veneer on your walls.
Functional Considerations
Paint is a coating. Plaster is dimensional. Earth plasters allow spaces to breathe, regulate humidity and even carry negative ions to neutralize electromagnetic charges from common office and household equipment. Paint carries a positive static charge so dirt gets readily collected on your walls. Earth plasters are bio-resonant so dirt and dander are actually repelled away from these surfaces.
Lime plasters are great for wet spaces to absorb and release moisture. Think Venice canals...viola! Venetian plaster was born. Then there is sumptious materials like Tadelakt, an ancient Moroccan plaster used in the centuries-old bathhouses. Go ahead, plaster your shower with this!

Eco-Faux
One reason "faux painting" turns me off is that alot of the products are acrylic and petroleum based and off-gas like your worst household cleaner! Give me a tannin stain, lime wash, or milk paint and it's a whole new beautiful world!
Earth plasters reflect the environment rather than copy it. Their chameleon-like textures can either reveal as ultra-contemporary or more casual and rustic. A nice contrast between ancient and modern. All take their roots in nature and that's what delights the senses the most!

Favorite Picks
I finished my first wall in 2001. As time goes by I continue to gravitate towards earth-based materials. Somehow the tubes and tubs of acrylics have become buried deep in the confines of my garage.
Here are my top picks for natural paints and plasters:
