Product is very easy to apply- I sprayed with a pump sprayer and the wife rolled it out with a paint roller. Beautiful results! It really brought out the color of our stamped concrete, which had faded over time. Also, the gloss can't be beat. Being we live in California, we had to purchase the AR500, which is a lower VOC formula. It still has quite a strong solvent odor, which lasted for approximately 3 days. If you are applying this upwind of your house, be sure to keep your windows closed! Very impressed with the product!
