A grid (10) for producing a pattern on a surface. The grid includes elongated members (12) connected together at intersections (24) and extending about a plurality of open areas (16) to form a mesh-like structure. Connecting members (26, 28) are connected to the elongated members at the intersections. The connecting members extend outwardly from at least one said elongated member. The connecting members have a thickness less than the thickness of the elongated members. The bottoms of the connecting members and bottoms of the elongated members are flush. The grid is placed on a surface and a liquid coating is spread over the surface in the open areas between the elongated members. The liquid coating is allowed to set. Preferably there is a removable coating on the grid which is removed after the liquid coating is set.
