Advantages

Protects concrete surfaces against the damaging eff ects of deicing salts, acid rain and staining.; Minimizes spalling due to moisture absorption and freeze/ thaw related damage.; Prevents unsightly stains caused by absorption of dirt, oil and grease.; Sealed surface makes contaminants easy to clean simply by wiping away or by using a mild detergent and scrub brush.; Gives decorative surfaces like stamped concrete a "wet look" and enhances the natural colors.; Resists ultra-violet oxidation and yellowing.; Off ers excellent water vapor permeability and resistance to blistering.; Dries rapidly and off ers excellent re-coatability characteristics.; VOC compliant for use anywhere in North America except CA and UT.; Compliant with USDA requirements for incidental food contact.

Maintenance

Wipe up all chemical, solvent or petroleum spills as soon as possible.; Remove dirt and debris by sweeping.; Wash periodically with low pressure water and scrub brush to help maintain surface luster.; Clean damaged coating areas promptly and recoat

Precaution

Due to the extremely low fl ash point, DUO-SHIELD is only recommended for exterior applications and is NOT recommended for interior or enclosed applications.; Acid stained fl oors must be neutralized before applyingDUO-SHIELD. Wash the fl oor with a sodium hydroxide solution, thoroughly rinse with water and allow to dry. Use litmus paper to verify that the fl oor has a pH greater than 7 before applying DUO-SHIELD.; Do not apply where moisture could contact the underside of applied DUO-SHIELD.; Do not use on concrete slabs with inadequately drained subgrade or treated surfaces to be covered with concrete or plaster.; Coating delamination (blistering) may occur if applied prior to allowing all surface bleed water to fully evaporate. A moisture saturated subgrade or a moisture barrier placed beneath the slab to be cured and/or sealed may increase the risk of coating delamination.; Do not use with other fl oor sealers, treatments, bondbreakers or adhesives without prior site test to determine compatibility and adhesion.; Any variations in concrete surface density may be highlighted by surface mottling after product application. Make test application to determine performance and appearance acceptability.; Do not use around sparks or open fl ame. Provide adequate ventilation.; Treated surfaces may be slippery prior to drying and when wet with water or liquids after drying.; X May damage vegetation or painted surfaces with contact.; Coated surfaces will ultimately oxidize (chalk) in time, necessitating reapplication.; Not recommended for application to frozen concrete surfaces or when ambient temperatures are below 40° F (4° C) and/or are expected to drop below 40 F (4° C) within 12 hours following application.; Do not apply DUO-SHIELD to concrete if substrate temperatures are below 40° F (4° C) or above 85° F (29° C). Best results are obtained when DUO-SHIELD is applied during the morning or evening hours and not in direct sunlight. Application of DUO-SHIELD in direct sunlight and under extremely hot conditions can result in solvent bubbling or blistering.; Avoid applying DUO-SHIELD in windy conditions, which can interfere with product performance and appearance.; Avoid over-application. Apply one to two light coats. Over application may prohibit vapor transmission and lead to blistering and delamination of the sealer.

Work Life

DUO-SHIELD combines a deep-penetrating silane and a low molecular weight acrylic resin polymer to seal concrete, repel water and provide stain protection all in one product.
