Just burned $300 on a bad concrete sealer job

Last month I tried that new 'one coat' acrylic sealer from the big box store on a 400 square foot patio. Looked great for about 10 days until the first rain hit. Now there's white blotches everywhere and the sealer is peeling off in sheets. I spent $80 just on the sealer plus a full Saturday of labor down the drain. Should have stuck with the solvent-based stuff I normally use. Anyone else have a sealer fail like this after a short time?

Try scrubbing it off with a muriatic acid wash before it bonds for good.

Did you try @rose_cooper's acid trick yet? It's the only thing that worked for me.
