Nail Pops
You may have noticed telltale bulges in your walls and ceiling over time and wondered what they were. These are small circles that protrude from the drywall but not very far: usually no more than 1/8-inch. Often they crack the paint around them. They might even run in vertical or horizontal lines.
– With the corner of the putty knife take out the bump and screw on.
– Apply the spackling product (non-shrink) with a putty knife and smooth it out. Use wood filler for trim work. Let it dry.
