Which statement best describes the recommended method for the second vinyl sheet relative to the first during installation?

• A. It should be placed at a 45-degree angle.
• B. It must be placed edge-to-edge with no overlap.
• C. It must overlap the previous sheet.
• D. It should be placed with a gap between sheets.

Answer: (C)

When laying vinyl sheets, the second sheet should overlap the first. This overlap ensures the seam is fully covered and can be sealed properly, which helps prevent gaps and edge lifting as the material expands and contracts with temperature and humidity. After placing the second sheet over the edge of the first, trim to fit and apply the seam seal as required by the product guidelines. If you tried to butt them edge-to-edge or leave a gap, you’d create a visible seam and a potential moisture trap or loosened edge.
