Dear Tim,
We hired a contractor to put a sealcoat on our driveway. I assumed that he had
used tar as a filler in the cracks. I really don't know. The filler was put into the
cracks and almost immediately, he did the sealcoat. The coat is dry, but the
filler is mushy when the weather gets warm. It has been a week and it is no
better. I have complained and he is coming today. I wondered if there is some
way we can get this stuff off our driveway, or repair what has been done already. Can you help me?

The contractor made a mistake by sealing right after the crack filler was installed. The liquids in the crack filler that need to evaporate for it to get hard have no place to go. The sealer is blocking the evaporation. I'll bet if you read the instructions on the crack filler they say to let it dry for 24 maybe even 72 hours before sealing over it.
I would wait for two more months to see if there is any improvement. You might get lucky and it could harden quite a bit. Next time use one of my Bid Sheets to find a professional.
