RECOMMENDED FOR:

Recommended for sealing colored or uncolored exposed aggregate concrete, stamped concrete, porous brick, manufactured and natural stone, stucco, slate, unglazed tile and flagstone.

FEATURES:

Fast drying and breathable.
UV resistant and non-yellowing.
Available as a concentrate for easy shipping and use.

VOLATILE ORGANIC CONTENT:

Meets all federal VOC guidelines as well as the SCAQMD rule 1113

COLORS AVAILABLE:

This product is available in a clear only (appearance is a milky white liquid)

RECOMMENDED FILM THICKNESS:

Two to three coats will yield approximately 2-5 mils wet depending on type of concrete and the concrete porosity.

COVERAGE PER GALLON:

300-400 square feet per gallon for broom finished concrete or concrete that is not mechanically finished. and 400 – 600 square feet per gallon when applied to mechanically finished concrete.

PACKAGING INFORMATION

This product is available in 1/2 gallon containers as a concentrate which mixes to make one gallon (volumes approximate)

MIX RATIO:

One component product, simply add to water and stir.

SHELF LIFE:

Approximately 1 year in unopened containers

FINISH CHARACTERISTICS:

Satin Finish

VISCOSITY:

Less than 100 cps (typical)

DOT CLASSIFICATIONS:

Not regulated

CURE SCHEDULE: (70°)

Allow material to cure until tack free to the touch between coats. Allow about 12 hours for Light foot traffic. For heavier foot traffic, aalow the material to cure for 24 hours. Note: The chemical resistance will improve over time until fully cured in about one week.

APPLICATION TEMPERATURE:

55-80 degrees F with relative humidity below 85%

PRIMER:

None required.

TOPCOAT:

Multiple light coats are recommended.

LIMITATIONS:

Do not use in the concentrated form, always dilute with water as specified.

Clarity of color or gloss may be affected by high humidity, low

temperatures or chemical exposure. Lighting like sodium vapor lights

may affect clarity.

Apply only as a fine spray mist in two to three thin even coats, DO NOT back-roll or back-brush.

Do not apply on rainy or foggy days or when rain is expected before a clear 24 hour rain free time is expected. Excessive concrete moisture or inclement weather will not allow the sealer to cure properly.

Substrate temperature must be 5°F above dew point and above 550F

All new concrete must be cured for at least 28 days

The surface must be completely dry before coating.

When applying the multiple coats required, allow each preceding coat to dry tack free before applying the additional coats.

Do not use for a slip resistant coating. Too heavy of an application or applications over dense smooth concrete may become slippery, especially when wet or unclean. A sample should be applied to evaluate the slip resistance and suitability for use in the intended conditions such as wet conditions, contaminants, humidity, and other factors known to alter in place floor slip resistance.

The sealed surface should be inspected periodically for thin application areas or traffic worn areas. Reapplied as needed for proper surface protection. Normal traffic may require reapplications yearly.

INSTRUCTIONS (NP415)

1) PRODUCT STORAGE: Store product in an area so as to bring the material to normal room temperature before using. Continuous storage should be between 55 and 85 degree F. DO NOT allowproduct to freeze. Material that is frozen CANNOT be used when thawed.

2) SURFACE PREPARATION:

All dirt, foreign contaminants, oil, laitance, curing agents and effervescence must be removed to assure a trouble free bond to the substrate Make sure the surface is completely dry before applying the sealer. In some applications, Pressure washing and power scrubbing may be necessary. The recommended surface profile is a CSP1. Surface preparation guidelines are written by ICRI and outlined in Guideline NO. 03732 Selecting and Specifying Concrete Surface Preparation for Sealers, Coatings, and Polymer Overlays. paints, sealers, and curing compounds. A suitable cleaning solution can be used to clean the surface when required. If acid etching is used to clean or profile the surface, the slab must bethoroughly neutralized after the acid is rinsed from the surface. Follow the acid manufacturers recommendations. After acid cleaning, the, surface must then be flushed with clean water and neutralized with a pH neutralizersuch as ammonia, baking soda, or T.S.P Repeat rinsing and neutralizing until the concrete is thoroughly neutralized. Acid residue left on the surface will prevent the sealer from penetrating. After all the concrete preparation work is performed, allow the surface to dry for at least24 hours. Before applying the sealer, test the surface by placing a spoonful of water on the surface. If the water beads upon the surface, additional cleaning and testing must be done. Hydrostatic pressuremay affect sealer performance. For applications over decorative colored concrete, surface preparation may have already been performed to apply the colorant. If the surface has already been cleaned and conditioned, then the coating can be applied without additional preparatory work as long as the floor is allowed to dry for 24 hours.

3) PRODUCT MIXING: This product ships in a concentrate and must be reduced with water before use. The ½ gallon container of the concentrate (as supplied) when mixed with water will yield one gallon of ready to use Sealer. Simply pour the concentrate contents into container that will hold at least one gallon of liquid and fill the now empty container with water one time and add this amount to the concentrate. The mix ratio of sealer concentrate and water is one to one by volume. After mixing the water and concentrate, stir well before using. Mix with slow speed mixing equipment to avoid introducing air into the material.

4) PRODUCT APPLICATION: APPLY IN THIN COATS after mixing per the above instructions. Always test a small area of surface to verify appearance and suitability.Apply a fine mist of 2-3 light and even coats with asuitable fine mist pumpable sprayer or a mechanical sprayer capable of spraying a fine mist pattern. Multiple light applications are recommended for proper performance.Avoid heavy application of the sealer. Allow each application of the sealer to dry approximately1 hour prior to next sealer coat application.CAUTION: Do NOT back-roll or back-brush. Allow surface to dry for at least 12 hours for light foot traffic or 24 hours for heavier traffic. Apply with temperatures between 55 and 80°F. Clean sprayer immediately with water after applying.

5) RECOAT OR TOPCOATING: No topcoat is recommended except multiple coats of this product. For periodic maintenance, an additional coat(s) may be applied as needed after the surface is properly cleaned.

6) CLEANUP:Use soap and water or a suitable solvent

7) FLOOR CLEANING:Caution! Some cleaners may affect the color of the products installed. Test each cleaner in a small area, utilizing your cleaning technique. If no ill effects are noted, you can continue to clean with the product and process tested.

8) RESTRICTIONS: Restrict the use of the floor to chemicals until the coating is fully cured (7 days)). It is best to let the floor remain dry for the full cure cycle as well.Dependent on actual complete system application, surface may be slippery, especially when wet or contaminated; keep surface clean and dry.
