1. An apparatus for dispensing a mixture to create an overlay to reinforce or repair a surface, said apparatus comprising:
a shell having an upper portion and a lower portion, wherein a cavity is formed within said shell, said upper portion being separable from said lower portion;
a linear dispensing slot formed in said lower portion of said shell, said slot extending through said lower portion to the exterior of said shell and being in fluid communication with said cavity, thereby providing an outlet for dispensing the mixture;
a stopper assembly positioned within said cavity, said stopper assembly comprising a horizontal member and a linear plug extending downwardly from said horizontal member, said liner plug sized and shaped to fit within said dispensing slot;
wherein said stopper assembly is selectively positionable in a raised position in which said linear plug is withdrawn from said slot to allow dispensing of the mixture, or in a lowered position, in which said linear plug engers and seals said slot to prevent flow of the mixture; and
a lifting post attached to said stopper, said lifting post adapted to move said stopper into said raised position or said lowered position.
