Concrete driveway - questions about sealing

I just had some cracks fixed in my sloped side driveway. The job turned out great. (The photo is pre-repair.) The house is 35 years old and we've owned it 20 years. When we moved in, the light gray sealer between the concrete sections was already there. Much of it is still in pretty good shape, but some is finally failing and falling out. I'd say whoever did it used good material and did a good job for it to still be there all these years later. Out front, there's a 15 year old circle drive . It's flat and does not have sealer in the joints. I now plan to pressure wash and seal both driveways, and to put sealer in all the expansion joints. My questions: Dig out & replace just the failed expansion joints, or all of them? (I do want them to match.) What's the best sealer for those joints? What's the best sealer for the concrete? Spray or roll the sealer on the concrete? BTW, in case it affects your recommendations we're in Missouri. Temps range from 110 to -10. High humidity in summer. Any advice appreciated. submitted by /u/bcad4me [link] [comments]

My questions:

  • What's the best sealer for those joints?
  • What's the best sealer for the concrete?
  • Spray or roll the sealer on the concrete?
