Krystal 25 Emulsion EF 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, both inside or out, above, on, or below grade. It provides an alternative to solvent-based materials where solvent fumes may be objectionable.
Once it is dry, it is resistant to water, dilute acids and alkali, oils and fats, as well as air borne contaminants. It completely complies with all VOC regulations nationwide.
- 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. If using a power sprayer, we recommend Kaufman Products, Power Sprayer, because it was specifically designed for quick and even applications of emulsions as well as oil thinned cures. 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. If applying to preexisting concrete, the surface should be predampened with clean water. Do not apply over puddles. A pre-dampened surface helps to provide a glossy, uniform surface. Subsequent coats should be applied on top of dry Krystal 25 Emulsion EF.
Clean equipment with clean water before the product dries. After drying, Curing Compound Remover or strong solvents, such as Xylene, MEK, or Toluene will soft and help to remove the film.
The use of SureGrip, added directly to Krystal 25 Emulsion EF prior to application, will provide a slipresistant surface.

Safety & Health
- Precautions
Both Krystal 25 Emulsion EF and the substrate must be at least 42°F before application. Not designed for immersion in strong chemicals or prolonged exposure to gas. 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. Never apply over puddles. Although compatible with many 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. Read Safety Data Sheet before using.
