This is my first time sealing concrete, I just had a patio poured in the spring and I wanted to make sure it lasts as long as possible without stains since I have a BBQ and table that young kids will be using. This product is very easy to apply via garden sprayer and the coverage was pretty spot on to what the label said. I have some parts that the water beads up although it's very clear from the instructions that this is not the intended result. There was no smell and it dried nicely. I was a little worried about the portions on my patio that were still in the sunlight at 5pm but there doesn't seem to be a difference between the sunny and shady areas. I hope this product lasts 7-10 years!
