I was dead set on using that spray-on sealer till I saw a crew's slab peel up

Been using the same solvent-based sealer for years, figured nothing could beat it. Then last Thursday I was walking past a jobsite over on Maple Street where they were fixing a driveway. The finisher pulled up a big sheet of sealer that had just delaminated from the concrete. He told me it was because the sealer didn't breathe right in their climate. That got me thinking about how much moisture we trap under those things. Now I'm looking into water-based options with better vapor permeability. Anybody had good luck with a specific brand that doesn't bubble up on you?

Funny how much the drying time matters too... I've seen guys rush a water-based coat on a humid morning and had it bubble up like a science experiment gone wrong.

Nah, just means you're using cheap paint.
