Posted By Brian Stone on 07 Sep 2010 11:35 AM I may be mistaken. I tried to look up the exact specs and all I could find on the Zodiaq website is the master specifications for Zodiaq applications. That form says the following:A. Install components plumb and level, in accordance with approved shop drawings and product installation details. 1. Tops: a. Flat and true to within 1/8" (3 mm) of a flat surface over a 10' length. This is my favorite. I can't imagine getting away with an 1/8" wide seam.B. Form field joints using manufacturer’s recommended adhesive, with joint widths no greater than 1/8" (3 mm) in finished work.
