Using an HVLP sprayer, or a pump-up sprayer for smaller jobs, spray Pentra-Sil® (244+) evenly on the surface. Spread out any pools with a soft bristle broom or a flat microfi- ber pad. Keep surface wet for at least 20 minutes, adding more material where needed. Surface is ready for use when dry, but the complete reaction may take up to two weeks to develop depending on site temperature and conditions.In cool, humid, or enclosed conditions, Pentra-Sil® (244+)may stay wet for a long time. After 1 hour of dwell time, use an auto-scrubber to rinse the surface and pick up excess material.If concrete is dyed, acid stained, or integrally colored, after 20-30 minutes of dwell time, use scrubbing equipment to rinse the surface and pick up excess material. After bringing the surface to the desired surface profile by grinding or buffing, Pentra-Sil® (244+) may be applied to enhance gloss, stain, and wear protection.
