Krystal 25 Emulsion will cure, harden, dustproof and seal concrete surfaces. This glossy, nonyellowing, premium quality curing compound & sealer is recommended over all types of concrete floor surfaces, inside or out, above, on, or below grade. It provides an alternative to solvent-based materials where solvent fumes may be objectionable. In addition, Krystal 25 Emulsion may be used on slate, flagstone, brick pavers, stamped concrete, artificial stone, and exposed aggregate Once it is dry, it is resistant to water, dilute acids and alkali, oils, and fats, as well as air borne contaminants. Krystal 25 Emulsion complies with both EPA & AIM Regulations from LADCO & OTC.
- Application
Surface should be clean, free of grease, oil, standing water and other foreign matter as per ASTM D-4258. Apply evenly with clean sprayer with nozzles specifically designed for high solids curing compounds, such as Chapin nozzle # 1-5937 or equal. Apply as soon as the surface is sufficiently hard, so that it will not be marred. Do not puddle. Short-napped rollers may also be used.
If using as a curing compound, apply as soon as finishing operations are completed and the surface will not be marred by the application. Do not apply over puddles. Subsequent coats should be applied on top of dry Krystal 25 Emulsion.
Although compatible with most carpet, tile, and floor covering adhesives, a test section is recommended for questionable adhesives.
Clean equipment with clean water before the product dries. After drying, strong solvents, such as Xylene, MEK, or Toluene will soften and help to remove the film.
The use of SureGrip, added directly to Krystal 25 Emulsion prior to application, will provide a slip-resistant surface.

Safety & Health
- Precautions
Both Krystal 25 Emulsion and the substrate must be at least 45°F before application. Not designed for immersion in strong chemicals or prolonged exposure to gas. AlI coatings may be slippery when wet. If intended to be used on smooth surfaces, in wet areas, apply 25 lb. per 100 ft2 of special aggregate on surface while coating is still wet. Allow to cure thoroughly before subjecting to full use.
If applied too thick, the film will not dry properly and will leave a white film.
Do not subject the coating to rain or water until it dries hard.
All clear sealers produce an uneven gloss on existing concrete due to uneven porosity of the surface.
This is especially evident when used on surfaces such as brick, pavers, and natural and artificial stone. Never apply over puddles. Although compatible with most carpet, tile and floor covering adhesives, a test section is recommended for questionable adhesives. This material is freeze/thaw stable, however if exposed to freezing, stir well before use.
