A spraying apparatus which is particularly suitable for spraying a marking stripe on pavement, grass, or other surfaces is provided with adjustable axles so that the distance of the spray can from the surface can be changed to vary the width of the stripe and with a wind screen which remains in the same relative position with respect to the surface as the axles are adjusted to protect the spray pattern from wind. The apparatus includes a somewhat box-like frame, and the sides of the frame are provided with generally vertically extending front and rear rows of openings for the front and rear axles. The frame includes holding means for holding an aerosol spray can filled with marking material, and the holding means are constructed and arranged so that the marking material is sprayed substantially below the front of the frame to permit marking stripes to be sprayed right up to an obstacle in front of the spraying apparatus. The wind screen extends around the outside of the frame, and each side of the wind screen is provided with a front and a rear opening through which the front and rear axles extend. The openings in the wind screen are positioned relative to the bottom edge of the wind screen so that the bottom edge will be positioned just above the surface to be sprayed. As the distance of the frame from the surface is varied by inserting the axles through various openings in the frame, the position of the wind screen relative to the surface remains constant since only one opening for each axle is provided through each side of the wind screen.
