Surface Preparation -  The concrete surface must be clean and free of standing water. Remove any sealer or other material that may prevent adhesion of CRYSTAL SHINE.  

Application to Fresh Concrete  - Apply at a uniform coverage by spray at 250-350 sq ft /gal.   Product may be sprayed with a hand held “pump-up” sprayer or an airless industrial sprayer. Best result are achieved when spray applied. If roller applied, use a short napped solvent resistant sleeve and avoid entrapping air (bubbles) 

When an extra high gloss is desired or on especially porous surfaces, two applications are recommended.  Allow the first application to dry for 1-3 hours or until surface is dry to the touch. 

Sealing Existing Concrete - the surface must be thoroughly cleaned and dried before applying CRYSTAL SHINE. Pressure washing with a strong alkaline detergent to remove dirt, waxes and oils is recommended.  Acids will not sufficiently clean or remove dirt, curing compounds, or old sealer from concrete. Worn or porous areas may need a second application for uniform sealing and appearance.  Allow 24 hours before 2nd application of sealer. In general, multiple thin coats (250 - 350 sq ft/gal) will provide a harder, more durable finish than a single heavy application. Dry time will be influenced by both temperature and humidity.
