What is the purpose of using a protector board when fastening tack strip in front of a finished wall?

Using a protector board when fastening tack strip in front of a finished wall serves a vital role in preventing damage to the wall or baseboard. When tack strips are secured, the potential for damaging the wall or baseboard with nails or other fasteners increases, especially in finished spaces where any marks or dents can negatively impact appearance and require repairs. The protector board acts as a buffer, absorbing impact and minimizing unwanted damage, thus allowing for a clean, professional installation without compromising the integrity of the wall surface. This precaution is particularly important in settings where aesthetic concerns are paramount, as the protector keeps the surrounding areas intact during the installation process.
