I need to overcoat my "driveway" this year. I did it 4 yrs ago by having it done. They came, trimmed the edges, then used a leaf blower to clear off the surface. They opened can after can and spread it around in a couple hours. Seeing that, I decided I could do it by myself. I looked around at different products. Went to HD and got their brand that was the next one up from what was used last time.. I pressure washed the surface, then primed the areas that had some oil stains. I filled the cracks.The area was dry, and it didn't rain for 5 days. After the first winter. the stuff just flaked off in big chunks. I was very disappointed. So, I am asking, what works best for you?
