In a sealing profile strip used to form a seal between one edge of a building component, such as a plaster board, and an adjacent building component, a mounti ng portion is adapted to cover a portion of an expansive surface of the first-menti oned building component when the sealing profile is installed along the edge of the first-mentioned building panel. A flange portion of the sealing profile is adapt ed to cover a portion of the edge of the first-mentioned building component when the sealing p rofile is installed therealong. For guiding a tool used to apply finishing material ove r the mounting portion, a rib portion of the sealing profile projects from the mountin g portion and joins the mounting and flange portions. Two resilient sealing lips p roject from the flange portion, each for forming a seal between the edge of the first-m entioned building component and the adjacent building component when the sealing profile is installed therealong. For protecting the resilient sealing lip when finishing ma terial is being applied, a tear-away strip projects from the rib portion. Being joined to the rib portion at a preferentially weakened juncture, the tear-away strip is torn away after finishing material has been applied. |
