At our company’s core, we believe the built environment should be constructed with sustainability in mind.  That way we all live in a healthier world.  We are doing our part by searching for and supplying materials that lighten the load on our planet.

There are many green or environmental aspects of using this stucco.  Because we supply it as a powder in bags, it weighs approximately 85% less than gypsum board.  Therefore more can be transported on the same truckload, reducing greenhouse gas emissions.  Also, the quarrying is 5-9 times more efficient than stone because we only need the powder and not slabs.  We recommend this stucco for homes in the United States, where the material comes from.  Using local materials is ecologically friendly, and ties the building to the local landscape.

Because of its reduced weight, stucco requires less structural support.  This means less lumber, steel, and concrete to produce, ship and install.  As a result, we are decreasing the use of our most widely used natural resources.

Historically in the building process, there has been inherent waste of material.  This material has filled landfills, instead of being repurposed.  Stucco can be returned to nature.  This translates to no waste.

This stucco does not contain any VOCs or other compromising chemicals or toxins.  It comes naturally from the earth, so it is inherently sustainable.  Stucco is also very low maintenance–no need for paint, sealers, or harsh cleaning products.  There is no off-gassing from toxic materials, finishes, or adhesives.  Stucco has been used in construction for thousands of years, and is still used in relatively the same form.

abrasion resistance: LOW

Stucco has low abrasion resistance.  Light scratching will occur with exposure to abrasive items. The finish can damage as a result of this scratching.

Absorption: Moderate

This stucco has a high absorption rate, which is an advantage for interior applications.  However, oil and highly pigmented liquids can penetrate and stain.  To reduce the appearance of stains, wipe up spills immediately.

Acid Sensitivity: Minimal

This stucco is minimally sensitive to acids.
