About Coatings


Applying the Art of Coatings

Sto delivers a full line of premium high performance coatings including primers, acrylic coatings, and elastomeric coatings that create dramatic visual appeal and safeguard your building’s value.
Sto architectural coatings and exterior coatings are able to repel wind driven rain, yet still allow a building to breathe. They are resistant to fading and buildup of dirt, mold and mildew for long lasting beauty. A variety of color and texture options within Sto’s product line give you a full array of design choices.

Sto Color

All our Coatings and Standard Finishes can be tinted to match any of the 800 Standard Sto Colors, as well as any of our selected Color Collections.

Sto Studio

Sto Studio is a unique visual service that facilitates design and color decisions with professional-grade renderings.

Product Features

  • Weatherproof
    Resists wind-driven rain and absorption of water in direct contact with vertical surfaces, offers superior UV resistance and deters growth of mold and mildew.
  • Vapor Permeable
    Allows a structure to breathe naturally so coatings are less likely to blister due to water vapor movement.
  • Crack Bridging
    Elastomeric coatings have high elongation properties, remain intact over hairline cracks caused by thermal changes in the substrate and offer excellent hiding properties.
  • Self-Cleaning Properties
    Lotus-Effect® coatings provide a durable surface that beads water and sheds dirt, keeping walls clean and dry.
  • High Bond Strength
    Bonds solidly to the substrate, whether brick, concrete, cement or continuous insulation.
  • Low VOCs
    Easy to apply, safe and non-toxic with low VOCs. Environmentally friendly and certified ISO 14001 operations.
  • High CO2 Diffusion Resistance
    Protects embedded steel in concrete structures from corrosion.

StoColor™ Lotusan®

Super-hydrophobic exterior coating with Lotus-Effect® technology.

StoColor™ Lotusan® is a smooth, vertical, above grade exterior wall coating with Lotus-Effect® technology for concrete, stucco, masonry and ci wall systems.
The StoColor™ Lotusan® exterior coating possesses a highly water-repellent, self-cleaning, surface similar to that of the lotus leaf. Its micro-structure has been modeled on the lotus plant to minimize the contact area for water and dirt. The surface lowers maintenance costs by extending cleaning and re-coating cycles.

StoColor™ Climasan®

VLC* Odor Neutralizing interior wall and ceiling coating.

StoColor™ Climasan® is an innovative interior wall and ceiling coating that when exposed to light source neutralize odors in the air. This easy to apply single component acrylic latex requires no special equipment or application methods. StoColor™ Climasan® contains Visible Light Catalysts (VLC) that continuously degrades organic compounds and pollutants remains active for as long as the coating is exposed to light.

Sto Acrylic Coatings

Preserve the value of buildings by serving as a breathable, durable and attractive layer of protection.

Sto Acrylic coatings bring a wealth of protective characteristics and aesthetic options to building design, extending the lifetime of a structure’s appearance and protecting it from the elements. Whether new construction or recoating, Sto Acrylic coatings preserve the value of buildings by serving as a breathable, durable, attractive layer of protection.

Sto Elastomeric Coatings

Decorative coatings which bridge hairline cracks and increase weather resistance and permeability.

Sto Elastomeric coatings can cover hairline cracks, dramatically improving a building’s appearance. High elongation properties help the coating remain intact over hairline cracks caused by thermal changes in the substrate and offer excellent hiding properties. Sto Elastomeric coatings resist wind-driven rain and absorption of water in direct contact with vertical surfaces. They also offer superior UV resistance and deter growth of mold and mildew.

Sto Textured Coatings

Create visual interest, hide imperfections and maintain a new look for longer.

Sto Textured Coatings are acrylic based coatings used over prepared vertical concrete, stucco or masonry surfaces. They are ideal to hide minor surface imperfections. They come in a wide variety of textures and colors utilizing the StoColor system and color collections.

Sto Primers

Prepare any type of substrate prior the application of Sto Finishes and Coatings.

Sto Primers can be used for priming prepared concrete, masonry, plaster, Continuous Insulation Systems base coats or drywall surfaces prior to application of Sto Finishes and Coatings. Available in both sanded and smooth textures, Sto primers promote uniform substrate absorption and can help maintain proper dry film thickness. In many instances, they can also lower your overall costs by extending topcoat coverage.
