I bought this to seal a stamped concrete patio, retaining wall block and concrete curbing. Worked great for all three and got the expected results I was looking for. High gloss, easy application and minor prep work. Made my neglected concrete curbing look like new again. All I did was pressure wash the surfaces and let it dry for a day and half. The instructions say to apply in the afternoon but I did it in the morning. I live in a very dry climate so I did not have issues with bubbling. I used a concrete sealer sprayer which saved a bunch of time, definitely worth the price of the sprayer.
