Air and Moisture Barrier Systems image

Air and Moisture Barrier Systems - StoGuard®

Seamless protection for the entire wall assembly.

Air Barriers are required in building walls, regardless of region or climate. Controlling air leakage through the building envelope is critical to achieving high building energy efficiency. Research has shown that air barriers can play a larger role in energy efficiency than increasing insulation thickness. But unlike building wrap barriers that are penetrated by staples and fasteners for their attachment, the StoGuard® System provides seamless control over air and moisture to improve building performance and occupant comfort.

{{}} {{this.hide}} Advanced Restoration for Building Facade Program - reStore

reStore Program image

reStore Program

The reStore program combines all of Sto's knowledge and resources to provide a comprehensive program that focuses on maintenance, repair, and energy improvements of existing EIFS, Masonry, Concrete, and Stucco structures.

The program helps to safeguard the long term value of your investment and helps your cladding meet the needs of today and the future. We combine our understanding of your goals to assist in developing a solution intended to enhance your investment, increase the performance of cladding and improve the look of the exterior. We work with Owners, Architects, Building envelope consultants, engineers and contractors to tailor a solution that will best help your design objectives.

Level 1 - CLEAN & RECOAT image

Level 1 - CLEAN & RECOAT

A basic program to remove dirt, mold and mildew, while refreshing or updating the color of the facade.

The clean and recoat process combines a thorough pressure washing and surface finishing with a high performance Sto coating. Sto coatings deliver far more than paint; they actually resist accumulation of dirt, mold and pollutants, preserving a building's value while enhancing its appearance and reducing maintenance needs. Sto coatings are integrally colored with high-quality pigments to complement building additions or to totally transform a structure's appearance.

You'll see real, quantifiable results when you protect your building with a Sto high performance coating, including improved resistance to water, mildew, cracks and fading.

Level 2 - REPAIR & FINISH image


A program to repair minor damage to EIFS or stucco facades before it becomes a major problem.

Cracking and other damage is repaired with a substrate-specific repair product. Often, an additional layer of basecoat with embedded mesh is used to restore the building exterior to its original condition. Sto repair products are engineered for most substrates, including EIFS, stucco, concrete and masonry.

After damage is repaired, a high performance Sto finish is applied to finish and seal the surface, protecting it from the elements and slowing down natural wear and tear. Now the exterior is resistant to wind-driven rain, UV rays, mold and mildew.

Level 3 - OVERCLAD image

Level 3 - OVERCLAD

A cost-efficient program to correct moisture intrusion problems and improve the energy efficiency and aesthetic appeal of brick, block or stucco facades.

Sto insulated wall claddings have the power to transform an unsightly, inefficient older building. Sto's latest Continuous Insulation innovation is StoTherm® ci Lotusan®, which integrates three key components into an energy-efficient insulated wall cladding system: StoGuard® continuous fluid applied air barrier, StoTherm® exterior insulated cladding and Stolit® Lotusan® textured finish with patented self-cleaning properties. This state-of-the-art system stays attractive for years, in addition to significantly increasing thermal heating and cooling efficiency while improving indoor air quality and lowering the overall lifecycle costs.

Level 4 - REMOVE & RECLAD image


For extensive renovations, it often is most efficient to start over with a new cladding.

Sto offers you options. Instead of extensive repairs, it's often more efficient to remove all existing cladding and replace with a superior, sustainable Sto wall cladding system that's extremely durable, improves building performance and looks fresh far longer.

When it makes more sense to reclad than repair, a Sto wall cladding system is the low maintenance, high performance solution. Sto can also overclad brick, block and stucco walls, dramatically improving curb appeal and extending the life of the building's exterior.
