This is a smooth, bonded polyester thread with wax coating that is specifically designed to prevent weeping seams! A wax coating on the thread plugs stitch holes to help waterproof seams in canvas and vinyl.

Bonded Coats Dabond^® polyester thread has high strength and stretch control, stability in sunlight (UVR), and resistance to needle heat, abrasion, saltwater and mildew. This polyester thread very seldom frays at the needle eye, and the consistent bonded finish minimizes the need for continual machine tension adjustments. Perfect for use on waterproof covers, tents, boat covers, awnings and tarps.

Use this V-92 thread with a #18 or #20 needle on 6–10-oz. fabrics (including all Sunbrella^® fabrics). We recommend a #20 needle when sewing with the Sailrite^® Ultrafeed^® Sewing Machine.

Sailmaker's thread should pull up off the top of the cone for a smoother feed to the sewing machine and to add an extra twist in the thread. The extra twist increases thread strength, helps keep the thread from unlaying, and eases tension problems.
