4. Choose and insert the right fixing for your wall type
Different wall types require different fixings. Knock on the wall or use a stud detector to find out what type of wall you’re dealing with. A hollow sound indicates a stud wall (otherwise known as a drywall) consisting of a wooden, brick or metal frame with plasterboard panels on top. A solid sound suggests your wall is a masonry wall, made from brick, breeze-block, concrete or stone.
