instruction: What is base board?
response: Base board is a wooden or vinyl board that is used in home construction or home remodeling projects.  It is used to decorate where sheet rock comes together to form a line on ceilings.  It is also used on the floor to cover where tile and wood planks come together to meet the wall (e.g. interior wall).  People use it here for aesthetic reasons because it looks nice.  You will need a miter saw to cut base board, and it should always be painted first before installing it with a nail gun.  When installing it it should be attached to the studs in the walls for a secure connection.
