Apply exactly in the correct location the first time. Attempting to remove DiSeal may damage the patch and roofing beneath it. Do not stretch the patch during application. Do not butt joints — do not try to cover large areas by placing DiSeal end-to-end or side-by-side. Use a squeegee with heavy pressure, starting in the center and working outward to remove any bubbles and ensure complete contact. Edges must have no openings, tunnels, or fishmouths.
