2 StoPowerwall Stcco Systems Faster, better, more economical and drable stcco installation from Sto, the leader in wall cladding systems. StoPowerwall NExT DrainScreen is an advanced, integrated system that combines the best protective and aesthetic elements into a sperior wall cladding. The system is comprised of several components inclding StoGard lid-applied waterproof air barrier, Sto DrainScreen drainage mat, StoPowerwall stcco and Sto textred inishes. Together these make a system that performs better than traditional stcco, with inishes and coatings that keep ot moistre while providing a myriad of design options. Flid-applied waterproof air barrier StoGard, the NExT component, is a lid-applied waterproof air barrier membrane that nites energy eficiency and drability, creating a continos waterproof air barrier beneath StoPowerwall claddings. Sperior protection against moistre intrsion Continos air barrier resists leakage and improves energy eficiency Improved indoor air qality Protection against mold and mildew Easy and safe to install Drainage Sto DrainScreen is a drainage mat between the cladding and the StoGard seamless waterproof air barrier. Shold water reach the area between the protected sbstrate and cladding it can drain from the wall assembly via the drainage mat, which also helps speed the drying of moistre-laden air (water vapor) that can accmlate in the wall assembly. Drainage and drying can be particlarly important in hot and hmid climates and in areas with wind-driven rain. StoPowerwall Stcco Sto s blend of Portland cement, ibers and other additives has ield-mixed stcco beat hands down for 1/2" to 7/8" stcco applications: Factory mixed for consistent qality High compressive strength and tensile strength for greater impact resistance and less cracking Enables lower weight per sqare foot becase it can be installed in thinner sections than conventional stcco Protects against moistre intrsion and looks better longer Faster installation with less ield mixing redces cost and improves qality Sto Textred Finishes and Smooth Coatings High-performance inishes and coatings extend StoPowerwall systems protective properties by resisting moistre and UV degradation, enhancing weather resistance and appearance over time. A comprehensive array of colors and textres gives architects the design options they desire. Cover photo: Sothface Eco Ofice, Atlanta GA. LEED Platinm Certiication 2 StoPowerwall Stcco Systems

StoPowerwall Stcco Systems Stand Apart from the Rest Locally prodced for the best vale StoPowerwall stcco is prodced locally from the best raw materials for the highest qality, most economical stcco application. Lightweight = cost effective StoPowerwall stcco can be applied at 5/8" over metal lath, thinner than conventional stcco so its strctral reqirements are less, saving yo time and money. Unmatched color selection and design options StoPowerwall inishes and coatings deliver excellent color niformity and a wide array of tint choices sing highly concentrated pigments that won t dilte material like niversal tints can. With a variety of textred inishes and smooth coatings and more than 1 million tint formlas, StoPowerwall pts cstom design options at yor ingertips. Why drainage? Hot and hmid climates and regions that experience wind-driven rain beneit tremendosly from a drainage mat in the wall cavity. This component is reqired in many regions and will likely be adopted more widely in the near ftre. Sto DrainScreen creates an air gap that promotes drainage and drying of wall assemblies.

6 Sto inishes and coatings cover all the bases Sto s integrally colored inishes and coatings protect against weather and deliver good looks that last longer. Sto textred finishes and smooth coatings provide the finishing toch to StoPowerwall stcco systems. Or finishes and coatings are manfactred in ISO-certified facilities to meet strict qality control standards. Sto elastomeric finishes se high polymer content and marble aggregate not qartz and are designed for maximm crack bridging and minimm pinholing. Low pinholing is essential when it comes to bilding pkeep and appearance. Pinholes give water and dirt a place to accmlate, discoloring srfaces and providing food for mildew and algae. Sto finishes provide a strong, flexible oter skin that protects bilding exteriors while keeping them looking cleaner for a longer time. And Sto finishes are available in virtally nlimited colors at no additional cost.

7 Sto Lotsan Featring Lots-Effect technology, a patented breakthrogh technology modeled on the niqe self-cleaning lots leaf, Sto Lotsan inishes and coatings are incomparable to any exterior prodct on the market. Like the lots leaf, the inish is rinsed clean with rainfall, thereby redcing maintenance costs. Sper hydrophobic, nprecedented water repellence Long-lasting crb appeal and redced maintenance costs Prononced self-cleaning properties Highly resistant to mold, mildew and algae Available in a variety of textres and colors Using Sto Hot Prime has many advantages, inclding blocking srface alkalinity, redcing stcco water absorption and minimizing eflorescence. Sto Hot Prime is also tintable to enhance the inish color and increase the yield of the inishes. StoPowerwall Stcco Systems 7

StoPowerwall stcco fnctions as a decorative and protective exterior wall covering and may also be sed on sofits, ceilings and interior walls. As with any exterior wall covering, the proper integration of other components of constrction, in particlar, the se of lashing to direct water to the exterior, is essential. Eflorescence is a normal occrrence in Portland Cement based prodcts and can affect inal appearance of inish prodcts installed over stcco. Some degree of cracking is normal in Portland Cement stcco and shold be expected. Cracking is generally not cased by a material defect in the stcco and can be minimized by following sond constrction practice sch as the proper installation of lath, the se of properly graded sand, the proper incorporation of stress relief joints in the constrction, moist cring of the stcco after it has been applied, and proper seqencing of constrction to avoid stresses in the freshly placed stcco. See or website for key details for bilding with stcco.
