Abstract: An apparatus is provided for applying a masking element adjacent a wall in a predetermined pattern. The masking element application apparatus includes first and second longitudinal members positioned at a predetermined distance from one another adjacent the wall and a dispenser for dispensing the masking element. The dispenser is carried laterally between said first and second longitudinal members and is slidable along said first and second longitudinal members from a first position to a second position. In operation, an end of the masking element may be attached to the wall when said dispenser is in said first longitudinal position and the masking element may be dispensed longitudinally along the wall by slidably moving said dispenser from said first position to said second position, thereby applying the masking element adjacent the wall in the predetermined pattern.
