Hey guys,
We just had our driveway resealed by a company today. This is the first time I've had a driveway resealed and so have very little experience with the process. I'm relatively happy with the job but one concern is that they didn't power wash the driveway with water before they sealed it. They scrubbed it with a wire brush and blew it off with a blower.
We had some kids driveway chalk on there which didn't come off with the brush/blower, so I went out there and asked them about it before they sealed. At first they said it's fine to just seal over it, but when I expressed some concern they said they'd brush it again, which didn't work. I went back out and explained it comes off easily with water, and helped them to go round and spot spray it with a hose and dry it up with the towel/blower. Most of it came off but they missed a few spots and sealed over it. During the process I scrubbed some of the water with a towel and it got pretty dirty, demonstrating that the driveway wasn't very clean. They said they don't power wash as they need the driveway dry to seal it.
My concern is that the sealant isn't going to bond well and won't last, but don't know enough about resealing to know whether this is a big deal. Everywhere I look online says to power wash before sealing. Anyone on here have any thoughts or insight on whether my concern is valid?
Thanks in advance.
