PACKAGING

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

Advantages

Complies with ASTM C 309, Type 1, Class A & B and, AASHTO M 148, Type 1, Class B. Compliant with USDA requirements for incidental food contact.; Application-friendly formulation allows more working time to roll or spread uniformly across the surface.; Penetrates deep into the concrete surface for enhanced breathability and less 'capping off' of the pores.; Contains special UV inhibitors designed to maximize resistance to ultra-violet degradation from the sun.; Dries rapidly and has excellent recoatability characteristics.; Protects sealed surfaces from the damaging effects of water, deicing salts and acid rain.; Minimizes spalling due to moisture absorption and freeze/ thaw related damage.; Prevents unsightly absorption of dirt, oil and grease.; Prevents staining and deterioration from airborne dirt, food products, urine and feces.; Minimizes efflorescence on decorative concrete surfaces.; NATRASEAL films provide good 24-hour spot resistance to many common chemical substances with little, if any, coating effect.; Protects subsequent applications of carpeting or vinyl composition tile from efflorescence, attack by alkaline salts and dusting.; A non-slip additive is available for improved slip resistance.; For a less glossy finish, a flattening agent is available that reduces the normal gloss level 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 low flash point, NATRASEAL is only recommended for exterior applications and is NOT recommended for interior or enclosed applications.; Acid stained floors must be neutralized before applying NATRASEAL. Wash the floor with a sodium hydroxide solution and thoroughly rinse with water and allow to dry. Use litmus paper to verify that the floor has a pH greater than 7 before applying NATRASEAL.; Do not apply where moisture could contact the underneath side of NATRASEAL.; 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 sealer is applied to concrete placed over a moisture saturated subgrade or a moisture barrier placed beneath the slab.; 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. Make test application to determine performance and appearance acceptability.; Do not use around sparks or open flame. Provide adequate ventilation.; Treated 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 temperatures are below 40° F (4° C) and/or are expected to drop below 40° F (4° C) within 12 hours following application.; Avoid over application. Apply one to two light coats. Over application may interfere with moisture vapor transmission properties which can lead to sealer blistering and delamination.; Best results are obtained when NATRASEAL is applied during the morning or evening hours and not in direct sunlight. Application of NATRASEAL in direct sunlight or under extremely hot and/or windy conditions can result in bubbling or blistering.; 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.
