Thermo-Shield® Stucco Shield is a water-based protective coating that can be applied in
place of paint, and as an alternative to the conventional and often costly three and more
part stucco systems. This unique wall coating can be applied quickly, is much less labor
intensive and provides an effective and durable thermal barrier. The base and finish coats
incorporate hollow borosilicate ceramic micro spheres. These micro spheres reflect, refract
and dissipate heat away from the coated surface. The formula also incorporates a 100%
acrylic polymer resin that allows the transmission of water vapor to escape, thus reducing
moisture build-up in the wall assembly. This flexible stucco coating bridges hairline cracks
and prevents the development of new ones.
Pre-mixed base coat and pre-mixed finish coat.
Stucco Shield is designed for interior and exterior wall surfaces as a flexible wall coating. It
can be applied over drywall, wood, steel, reinforced insulation board, brick, concrete block,
concrete and over existing stucco. It is designed to go on ready-to-paint surfaces that meet
local standards and building codes.
Base Coat, one hour to set and 12 hours to re-coat. Finish Coat, 40 to 70 hours to cure at
24 Deg C (75 Deg F) and 50% relative humidity.
COLORS AVAILABLE CONTAINER SIZE
White and custom colors available. Available in 5 gallon containers.
Two years. Store at room temperatures between 10 and 32 Deg C (50 and 89 Deg F).
Clean tools and equipment with soap and warm water; rinse with clean water.
Do not apply Stucco when freezing temperatures are expected within 48 hours or when rain
is predicted. Ambient temperature should be 10 Deg C (50 Deg F) or above for at least 24
hours; water-based coatings depend on evaporation to cure so avoid application in damp or
cold conditions. There must be good drying time of at least two hours before dew point.
Apply a coat of Stucco Base Coat to the entire substrate. Prepare corners and joints with
recommended corner bead, mesh and Stucco Finish Coat. Allow drying and then apply a
coat of Finish Coat to the entire structure (see application manual for more detailed
Stucco has a spray or roll-on viscosity. Commercial sprayers with texture guns can be
used to apply this coating. Various textures may be achieved, from a very fine sand finish
to a heavy plaster coat (see manufacturer's specifications for each individual sprayer).
Roller or airless spray application is recommended. Use a roller with a nap of 19mm or
airless spray unit with the following qualifications,
Tip orifice: .031 to .039 inch
Pressure: 2200 to 2500 psi
