Hi NA3905 - Thank you for your review. I'm sorry to hear that the paint dried too fast, causing streaks and clumps on your walls! To fix the finish, I recommend lightly sanding down the unwanted texture, wiping the area clean to move the sanding dust, then reapplying the paint when the air and surface temperatures are within the recommend range on the label. If the paint continues to dry too quickly, up to 4 ounces of water per gallon can be added to slow the dry time down and allow the paint to level out. For further assistance with your project, please feel free to reach out to us directly. We'd be happy to help. - Sara
