We’ve Made it as Easy as Possible


  • Light-weight Formula: With only dry lime + pumice aggregate, our plasters are up to 18 lbs lighter per bag than other options for the same volume of mixed plaster – the lightest lime plaster on the market! This translates to affordability, less fatigue on the applicator, reduced shipping costs, and a smaller carbon footprint.
  • Customer Support: As a company made by and for plasterers, we love trouble shooting tricky situations. With decades of experience, we’ve seen it all and are passionate about lime and plasterccraft. When you reach out for help, your questions will be answered by an experienced plasterer, not a sales person.
  • Affordable: With the capacity to manufacture at scale, Limestrong is uniquely affordable on a price per square foot basis.  Since our application systems are streamlined, the install process reduces labor costs as well.
  • Free Shipping: We understand the disappointment of buying an expensive bag of plaster and then seeing the price double with added shipping costs. Limestrong offers free shipping on all of our online plaster orders over $75.

 Healthy for You + the Planet


  • Safe: Limestrong plasters contain no petrochemicals, fragrance, VOCs or chemical additives.  Zero VOC means our plasters are free of toxic, carbon-based solvents that pollute the air and pose health risks.
  • Packaging: We ship our plasters dry and in biodegradable paper bags, resulting in much lower carbon footprint than when plaster is shipped wet. Wet plaster is heavy, costly to ship, and comes in plastic or steel buckets that eventually end up in the landfill.
  • Durable: When mixed, the ingredients in Limestrong plaster make a cementitious bond, resulting in a hard-wearing  strong surface that is abrasion and abuse resistant. Durability means longevity.
  • Made in the US: Cities and towns in US America were built with lime mortars from local kilns. One locale in Northern Ohio put US lime on the map with it’s finishing lime famous for it’s purity, bright white color, and plasticity. We’re lucky to get our raw lime from this same famed area. Our premium raw pumice comes from Hess Pumice in Southern Idaho and we blend and ship our plasters there too. Blending and shipping from the source reduces the transport steps for a reduced carbon footprint.

Our Story


Meet Ryan Chivers, Limestrong owner and master formulator. Ryan is the original visionary who set out to change the fact that he couldn’t find a lime plaster made with US-sourced materials that was easy to apply and affordable. As a life-long plasterer and lime geek/mad scientist, Ryan made it happen. Read his story and the story of Limestrong here.

Ryan jumped in the plaster trenches in Colorado in ‘99 as a young twenty-something eager to explore eco-friendly building and strawbale construction. Having some experience working for a relative’s high-end drywall company, he was naturally drawn to wall finishes in natural building. At the time, strawbale building was exciting territory, but the standard practice of spraying-on cement stucco and latex painted drywall didn’t sit well with him. This led to his discovery of lime and clay based plaster systems.

In 2001, Ryan started a plaster business, Artesano Plaster, specializing in lime, clay, and gypsum-based finishes. With lime plaster finishes, most roads eventually lead to tadelakt, the ultimate in lime plastering technology, and Ryan was no exception. Hit by the tadelakt bug in 2004, all he could find about tadelakt was in French or German. Despite the barriers, Ryan translated and experimented enough to learn and practice the basics. Eager to learn more, he traveled to Morrocco for tadelakt training in 2005.

Once back, Ryan began experimenting with plaster formulas mimicking what he learned in Morrocco. Inspired to use traditional lime plaster techniques in more modern applications, Ryan sought out local lime and experimented with different aggregates. Over ten years and extensive trial and error, Ryan became an expert in making lime plaster formulas, including tadelakt and the technique of tadelakt.

By 2010, Ryan had become a missionary of sorts, passionately sharing his love for locally-sourced lime and tadelakt as he taught throughout the United States and internationally. He traveled to Mexico, Canada, Colombia, Costa Rica, and New Zealand, to work and train others in Tadelakt techniques, always making a point to use locally sourced materials and refining and perfecting his plaster recipes.

The golden thread of sourcing local and sustainable materials became a guiding ethos when Ryan was invited to collaborate on a line of interior finish lime plasters in 2015. Synthesizing decades of experience, Ryan created Limestrong Artisan Finishes. When Ryan took the lead role with the Limestrong Artisan line in 2019, his dream of making high quality, affordable, accessible, and locally-sourced lime plasters became a reality. Today, Ryan is at the helm of Limestrong development, promotion, training, and technical support and continues to manage a thriving plastering business in Salt Lake City.
