Onceapplied, the working time is up to 20 minutesdepending upon material, ambient temperaturesand surface conditions.IMPORTANT:Apply coating in a continuousapplication, always working from a wet edge toeliminate cold joints. Minor shade variations mayoccur from batch to batch (refer to batch numberon pail).Avoid installing separate batches side-bysideand avoid application in direct sunlight.LimitationsBenefitsConcrete and masonry surfaces: Surfaces mustbe free of all bond-inhibiting materials, includingdirt, efflorescence, form oil and other foreignmatter. Loose or damaged material must beremoved by waterblasting, sandblasting ormechanical wire brushing and repaired.Avoidapplication over irregular surfaces. Resurface,patch or level surfaces to required tolerance andUse StoSilco Shield only when surface and ambienttemperatures are above 40°F (4°C) duringapplication and drying period. Dark colored finishesare not recommended for use over ExteriorInsulation and Finish Systems (EIFS). Select finishcolors with a lightness value of 20 or greater whenused as part of an EIF System. StoSilco Shieldshould not be used on horizontal, below grade orwater immersed surfaces. Do not apply if thesurface temperature is less than 5°F (2.8°C) abovethe ambient dew point temperature.Repels water; resists wind driven rainDoes not soften at high temperatures; maximum resistanceto dirt and airborne pollutantsAllows substrate to breathe naturally, resists blisters causedby trapped water vaporExcellent color retentionSafe, non-toxic, cleans up with waterSafe for workers and the environmentsmoothness with appropriate Sto leveling materials.Fill surface voids. Refer to ASTM D-4258 and ASTMD-4261 for complete details on methods ofpreparing cementitious substrates for coatings.Exterior Insulation and Finish Systems (EIFS):Surface must be clean, sound, dry, frost-free, andfree of all bond-inhibiting materials, including dirtand efflorescence.Protect from rain, freezing, and continuous highhumidity until completely dry.Curing/DryingStoSilco Shield dries within 4 hours under normal[70°F (21°C), 50% RH] conditions. Drying timevaries with temperature/ humidity and surfaceconditions.Clean UpClean tools and equipment with water immediatelyafter use. Dried material can only be removedmechanically.Sloped surfaces: minimum required slope is 1:2(27°) and maximum width is 12" (300 mm). StoMesh embedded in Sto Flexyl is required beneathfinish coating. Increase slope for northern climatesto prevent accumulation of ice/snow and water onsurface. Periodic inspection and increasedmaintenance of coating may be required.Application of StoSilco Shield below grade is notrecommended.Health And SafetyHealth PrecautionsProduct is water-based.
