PACKAGING

Product is packaged in 1 gal (3.8 L) jugs, 5 gal (19 L) pails and 55 gal (208 L) drums.

Advantages

Available in two different versions to comply with federal and regional VOC requirements.; Sparkl-Seal 350 350 and Sparkl-Seal 350 700 comply with ASTM C309, Type 1, Class A&B; and AASHTO M148, Type 1, Class B.; Compliant with USDA requirements for incidental food contact.; Contains special UV inhibitors designed to maximize resistance to ultra-violet degradation from the sun – maximum resistance to yellowing and chalking.; Dries quickly and can be easily top-coated.; High moisture vapor permeability (MVP) properties provide excellent resistance to blistering.; Protects sealed surfaces from the damaging effects of water, deicing salts and acid rain.; Minimizes concrete surface spalling due to moisture absorption and freeze/thaw related damage.; Prevents unsightly absorption of dirt, food products, oil and grease.; Prevents staining and deterioration from urine and feces.; Minimizes surface discoloration (whiting) resulting from efflorescence.; Provides excellent 24-hour spot resistance to many commonly used chemical substances.; A non-slip additive is available for improved slip resistance.; For a less glossy finish, a flattening agent is available that reduces gloss by up to 40%.

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 flash point, Sparkl-Seal 350 is only recommended for exterior applications and is NOT recommended for interior or enclosed applications.; Acid-stained concrete must be cleaned of all salt deposits and neutralized before applying Sparkl-Seal 350. Using a stiff bristle scrub brush, wash the floor with a sodium hydroxide solution, thoroughly rinse with water and allow to dry. Use litmus paper to verify that the floor has a pH greater than 7 before applying Sparkl-Seal 350.; Do not apply where excessive moisture could contact the underside of applied Sparkl-Seal 350.; Do not use on concrete surfaces with inadequately drained subgrade or on treated surfaces to be covered with concrete or plaster.; Sealer delamination (blistering) may occur if applied to fresh concrete prior to allowing all surface bleed water to fully evaporate. A moisture saturated subgrade or a moisture barrier placed beneath the concrete slab may also increase the risk of sealer delamination.; Do not use with other floor 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. Perform a test application to verify performance and appearance acceptability.; Do not use around sparks or open flame. Provide adequate ventilation.; Sealed surfaces may become slippery when wet with water or other liquids.; May damage vegetation or painted surfaces with contact.; Exterior sealed surfaces will slowly oxidize in time, eventually necessitating reapplication.; Not recommended for application to frozen concrete surfaces or when ambient or substrate temperatures are below 40° F (4° C) and/or if ambient temperature is expected to drop below 40 F (4° C) within 12 hours following application.; Best results are obtained when Sparkl-Seal 350 is applied during the morning or evening hours and not in the direct sunlight. Application of Sparkl-Seal 350 in direct sunlight or under extremely hot and/or windy conditions can result in bubbling or blistering.; Avoid over-application. Apply in one or two light coats. Over application may interfere with moisture vapor transmission properties which can lead to sealer blistering and delamination.; Due to the more restrictive air quality regulations written by certain VOC management districts regulating the use of architectural coatings, this product may be prohibited from use as a concrete sealer, but still permissible for the use as a concrete curing compound.
