The problem with this stuff is that it is too stretchy and soft, particularly in hot weather. Since it must be secured with stitching, it is not much of a time-saver compared to a sewn repair.īottom Line: Not for canvas repair. Like the nylon tape, it readily creeps in hot weather. This is fine for spinnakers but it creeps at very low load and sticks poorly to the fuzzy surface of Sunbrella.īottom line: Not for canvas repair. For durability, it is important to round any corners repaired with tape. It is so flexible that Sailrite recommends reinforcing any edge repair with a bit of monofilament nylon folded into the crease of the patch.Īdhesive and tape-based repairs on dodger canvas don’t leak as a sewn patch may. Tear-Aid Type A takes the flexibility approach much farther, with a tape made of soft vinyl that can conform to radical curves and over seams. However, the patch must be secured with stitching after placement if sustained stress is involved. They will be an acceptable solution for small repairs that have little or no strain. However, none of the tapes we tested held a sustained load without creeping, particularly in summer temperatures. At a minimum, new fabrics should be scrubbed vigorously with TSP before attempting a repair.īecause they are made of materials similar to the Sunbrella, tapes avoid the flexibility problem. The glues do not soak as deeply into new fabrics and water-repellent finishes almost certainly interfere with bonding. Sails held fast.Īlthough we did not quantify this, we believe that repairs should be made using used sailcloth or Sunbrella whenever possible. When other epoxies would begin to peel at peak strain (the fabric stretched more than the glue), Dr. Sails has maneuvered around this with a more flexible epoxy that cures to 80 percent strength within 30 minutes and completely within hours. We learned this when testing sewn rope splices (see Stitching Versus Splicing, PS October 2014 Dyneema thread made weaker repairs than polyester twine because the force was not distributed, and it cut right through the polyester rope. Matching the flexibility of the fastening method to the flexibility of the base material is vital to obtaining a strong, flexible repair. These were aged in the sun for three months and then run them through a dozen laundry cycles, including three hours of tumbling dry with no heat and with tennis balls added to increase impact and flexing. We then made up 6-by-8-inch flags from each material, with a seam running horizontally. These samples were slowly pulled to failure. For adhesives we allowed a 1-inch overlap and allowed the adhesives to cure for one week in hot humid conditions. The tape was firmly smoothed with a seam rubber and the samples allowed to rest overnight. For tapes we used a butt join with tape on both sides. Then we made up 2-inch wide cloth strips and created a seam for pull testing. How We Testedįirst, we tested several control samples of Sunbrella with sewn seams. We tested all materials on used Sunbrella canvas, which we laundered and scrubbed with TSP to remove any residual water repellent treatments prior to testing. We tested adhesives, including polyurethane and polyether caulks, fabric glue, epoxies, and a specialized sail repair adhesive, Dr. Whatever needs a quick fix Tenacious Tape will handle it – allowing you to stay outside longer.We tested polyester and nylon self-adhesive repair tapes, and a specialized repair product, Tear-Aid A.
