`
`Sto Guard™, a seamless, fluid-applied air and moisture barrier,
`provides superior protection under most claddings.
`It does what other wraps only pretend to do.

`
`ATLANTA – (March 1, 2003) Sto Corp, the innovative world leader in cladding, coating and
`restoration systems, is positioning Sto Guard™ to be the most effective air and moisture barrier
`behind most claddings in the commercial and residential markets.
`
`Sto Guard™ is a breathable, fluid-applied air & moisture barrier, providing superior protection against
`air and moisture intrusion in a variety of applications, including underneath brick, wood, vinyl,
`cement siding and exterior insulation and finish systems, and even cement stucco if used in
`conjunction with a bond breaker.
`
`Problems that can occur because of air leakage and condensation are minimized because Sto Guard™
`is an effective and economical means of controlling moisture in wall assemblies. By constructing an
`airtight building envelope the risk of moisture problems – decay, corrosion, loss of insulation value,
`mold growth and IAQ (Indoor Air Quality) are minimized.
`
`Sto GuardTM consists of three products:
`
`1. Sto Gold Fill—a spray or trowel applied joint treatment
`2. Sto Guard™ Mesh—a 9.5 or 4.25 inch (108 or 241 mm) wide adhesive reinforcing mesh used in
`conjunction with Sto Gold Fill
`3. Sto Gold Coat — a waterproof coating applied by spray, roller or brush to wall sheathing surfaces
`treated with Sto Gold Fill®, or to prepared concrete or concrete masonry wall construction.
`
`Together these three components create a structural air barrier and moisture barrier that greatly
`improves resistance to air leakage and water infiltration resistance in comparison to sheet goods in
`wall assemblies.
`
`The purpose of an air barrier in wall construction is to minimize air infiltration and exfiltration through
`the wall construction. The benefits are:
`
`• Reduced risk of condensation caused by air leaks through the wall construction.
`Increased thermal efficiency of the wall construction
`• Energy cost savings
`• Increased occupant comfort
`• Provides opportunity for pressure equalized or pressure moderated wall system
`design, thus minimizing the risk of rain water penetration through wall construction
`• Efficient use of materials--doubles as moisture barrier in wall assembly (in the case
`of Sto Guard™)
`
`“The purpose of a moisture barrier in wall construction is to protect against ingress of incidental
`water into the building and to protect moisture sensitive components such as gypsum based
`sheathing in the event of a breach in the outer wall covering, such as a crack in stucco,” said Alec
`Minne, Sto Marketing Group manager.
`
`Finally, know that Sto Guard™ is not a vapor barrier. The purpose of a vapor barrier in wall
`construction is to minimize water vapor diffusion through the wall assembly and thus reduce the risk
`and the amount of condensation on cold surfaces in the wall assembly. The term vapor retarder is a
`better term to use than vapor barrier when describing materials with low water vapor permeance.
`Very few materials have zero (0) water vapor permeance. Vapor retarder placement in the wall
`assembly depends on climate conditions and other factors.
