I just had my basement boarded with drywall along with 2" dow foam board insulation. Boarding was good and level. However, paint contractor did a extremely poor job in mudding the wall. After painting all bumps showed up wherever two boards meet. Is there any simple solution to make those joints appear smooth. It looks terrible after spending a good amount of money. By the way, I tried to attach an image file...though format and size both are correct I still can not upload it. I'm running out of money and looking for a simple solution which is not too labor intensive. Your assistance in this regard will be highly appreciated.
