I recently had my 1600 sq ft. driveway power-washed. I then hired a local guy to seal it. He used Thompsons.
What I have now is a mess. This driveway is about 17/18 years old. It appears that when they poured it, they let many stones come right to the surface. It is solid, but a patchwork of concrete and stones. That is where the mess shows up.
The Thompsons soaked into the areas where there was concrete, but didn't soak into the stone sections. It looks like a patchwork quilt, sewed by an old lady on drugs. Some areas are gray (even though he used Clear) , some white, and a lot are streaked (apparently due to the sealer guy using a large push-brush but not using enough material to cover properly.)
I called the sealer guy back. He said "I've never seen anything like this". He tried to spray some additonal Thompson's on the driveway, but that didn't do much, if anything. He won't be back, I am sure.
Anyhow, bottom line now...is that the Thompson's is sealing the driveway alright. Water beads and runs off pretty well. The appearance, though, is as if I had never cleaned it at all.
While talking to a guy at Sherwin Williams, I learned that the Thompson's should wear off enough in six months so that another power-washing will remove it. Is that true?
If and when I get it off, I am considering just using Black Asphalt driveway sealer over the concrete. That would cover the blotchy affect of stones and concrete. Can I do that?
This is a Summer house, so I don't want to spend a ton of money replacing the driveway.
Any help or advice appreciated.
Thank You.
