Abstract: A paint guide is particularly suited for use in painting large, exterior surfaces such as parking lots, warehouse floors, walkways, and curbs. The paint guide is formed of two frames, each having a rectangular planar base with at least one longitudinal side defining a planar surface perpendicular to the base. Each frame has an upright member at both of its latitudinal sides. The two frames are connected together at the upright members with releasable fastening means. Both the angle and the distance between the two bases can be adjusted so that the guide can be used both on flat surfaces and on outside corners.
