This sealer worked great!  Applied to stamped and colored concrete patio and pool deck.  Really enhanced the look and color.  Also brushed onto concrete faux rocks around pool.  I ordered a sample bottle and the no -slip fine sand additive directly.  After a trial run, I rolled two coats of this product on.  Dried over 4-5 hours.  Some fumes during install but went away overnight as it cured.  Highly recommend this product.  Arrived earlier than original estimate too.
