Recommendations for sealing driveway

[allinon72]

Wanted to get the concrete experts advise on sealing my driveway. The backstory - I have a normal 2 lane driveway leading up to my garage and had a 3rd parking lane added about a month ago. Obviously the new concrete is gleaming clean and new while my existing (7 years old) is not.

I want to pressure wash the old and get it as clean as possible to match the new concrete and seal the whole thing to maintain it. I’ve purchased Simple Green driveway cleaner that I plan on applying with a foam cannon and pressure washing accordingly.

My questions are:
- What sealing product should I use? I want it to last and willing to pay for it if needed. I don’t want to do it again in a few years
- Is 30 days enough time on the new slab to seal it?
- Should I be using a different cleaner than the one I referenced? I want the old to match the new as close as possible.

Thanks in advance.

From what little I know (or don't know) sealing is primarily for retarding the cureing for overall strength and shouldbeappliedas soonas you can walk on it. I've only done it on my shop floors, once with a high VOC solvent based (good stuff) and once with a water based sealer.
The water based is gone with the slightest bit of even just WD 40 mist settling on it.
I've also heard that solvent based is no longer available.
Someone in the business should be along with something much more assuring than my response.

Wait 30 days and use a silane or siloxane based sealer. It will be a penetrating sealer that lasts 7-10 years. It won't change the appearance of the concrete either. Solvent based will penetrate better than water based.

I reccomend Ghostshield 8510.
