Dutton-Lainson DuraPatchUV Repair Patches: Sizes & Application

DuraPatchUV is a self-adhesive repair patch that hardens when exposed to UV light or sunlight. Dutton-Lainson offers four sizes, from a small 2 × 3-inch sheet to a 9 × 12-inch patch. All use reinforced polyester/plastic construction and arrive protected from light until application. Choose the size based on the prepared repair area and the margin required by the product instructions, not just the visible damage.

DuraPatchUV sizes and model numbers

MPN Model Nominal dimensions Uncut area
56711 DP23 2 × 3 in 6 sq in
56712 DP36 3 × 6 in 18 sq in
56713 DP69 6 × 9 in 54 sq in
56714 DP912 9 × 12 in 108 sq in

All four patches can be cut to the size needed while protected from UV light. Allow sufficient material to cover the prepared area; a smaller patch may be easier to handle in a confined space, while a larger sheet gives more flexibility for trimming. Cutting a larger sheet does not mean every application or surface is suitable.

Material and repair suitability matter. Dutton-Lainson says DuraPatchUV bonds to various substrates including polyethylene, fiberglass, metal, glass and wood, but specifically excludes polypropylene. Identify the actual surface material before ordering. The product description alone does not establish suitability for structural repairs, a pressurized system or potable-water-contact use.

How the UV-cure patch is applied

1. Prepare and trimClean and dry the compatible surface. Keep the sheet out of sunlight while trimming. Return unused material to the protective foil pouch.
2. Position the patchRemove the backing from the sticky resin side, apply it to the repair area and press firmly. Avoid handling it as though it were already cured.
3. Expose to UVRemove the outer protective film and expose the repair to suitable sunlight or UV. Curing depends on the intensity of the exposure; follow the manufacturer's instructions before loading or finishing the repair.

Check the repair surface first

  1. Identify the material. The manufacturer lists multiple bondable materials, including polyethylene, but explicitly excludes polypropylene. Do not identify a tank or panel's plastic from its appearance.
  2. Check access and exposure. Plan how the complete applied area will receive the UV exposure needed to cure. A shadowed or enclosed location can require a suitable artificial UV source.
  3. Prepare before opening the packet. Remove dirt, water and other contamination. Leave the patch in its protective pouch until the work area is ready.
  4. Check intended service. For tank, roof, load-bearing, pressure-containing or drinking-water-related repairs, confirm the substrate and the component manufacturer's requirements rather than assuming a general repair patch is approved.
  5. Follow the supplied instruction sheet. The manufacturer describes a light-dependent cure, not an instant hardening adhesive. Do not paint, drill, load or expose the repair to service before complete cure.
