Applied it 3 days ago to a 11 year old concrete driveway that I had pressure washed a few days before. I used a pump sprayer to apply it. It has the consistency and appearance of milk. I had about 2000 Sq Ft to cover so it took me about 3 hours to apply 10 gallons. I waited until evening so the concrete would not be too warm and the sealer would be absorbed rather than evaporate. A few days after the application it rained and the water beaded up. I ordered an addition gallon to seal some sidewalks. After the rain the difference between the seal and untreated sections of sidewalk was easy to see. Sealed was light colored concrete and the unsealed was darker from absorbing water.
