Do Not Use Pens, Felt Pens or Chalk Lines!
When you are doing your next drywall project, moulding installation, or any other project that will be visible in your home and painted… do not use any ink based marker (felt pens or ink pens) or chalk lines on any surface that will be visible on completion. These types of markers will bleed through latex primer and paint. Considering that 90% of paint used in homes today is latex, it is a safe bet you will be using latex paint as well.
Play it safe and only use pencils for marking out cut lines, holes and so on. Pencil marks will not bleed through latex paints
