PRELIM: 4 homes owned over the last years 30 years with multiple driveways sealed.
DRIVEWAY: 35 year old, 2100 sq ft, 1/2 circle driveway, fine stone, previously sealed (10+ years ago) currently in southern New Hampshire. Yes, there were a few cracks we took care of with both liquid sealant (gallon size) for the smaller cracks, as well as the meltable, rubberized, rope-type for a few larger cracks.
COVERAGE: AWESOME !! My son & I used 11 buckets with an 18-inch squeegee (7 on the 1st coat, 4 one the 2nd)...this included 2 coats on all the edges with an asphalt brush.
We inverted the buckets 24 hrs in advance eliminating the need for ANY stirring (we "stir checked" the 1st 3 buckets but then none thereafter because we were surprised at how well it was mixed). That said, the recommended coverage of 250-350 sq ft per bucket is spot on, depending on final/showing aggregate size and /or any previous sealing.
DRYING TIME: 2nd coat states 3-6 hours or dry to the touch. We had to good day at 87F with partial sun helping. As such, we were applying our 2nd coat at the 4 hour point. As we're currently having a 3 day stretch w/o rain in the forecast (unusual for New England), we plan on prohibiting circle driveway access for a few days.
NOTES: Oddly enough, 1 car and 1 person on a sweet HD pulled up to chat at the end of the driveway. I gave them the info after the stopped talking about how great it looked (we were nearing the end of the 2nd coat). Some people comment about the color not being "black" enough...It's driveway sealer...it's black...it doesn't dry the same color as it is when its opened...driveway sealer never does. I tried to attach a pic of nearly "1/2" of the circle + a walkway so you can compare the main street and the driveway but after 3 different format attempts, Sam's Club system wouldn't allow me...it's black...driveway sealer black...period.
FINAL THOUGHT: This product is such a great value that, in fact, I plan on doing the 2nd half...oh yeah, we have another 2100 sq ft driveway & walkway in the back of the house !! Cheers all !!
