SURFBOARD REPAIR KIT
Epoxy or Polyester ?
EPOXY: FITS ALL SURFBOARDS | POLYESTER: USE ONLY FOR POLYESTER SURFBOARDS !!
Which surfboard repair kit you should choose depends on the blank material your surfboard is based on. Most boards are based on Polyurethan (PU) and are laminated with polyester resin. For PU boards use our red polyester surfboard repair kit, however you can also use the blue epoxy repair kit. If you have an epoxy board based on expanded Polystyren (EPS) or extruded Polystyren (IX-PS, XPS), use the blue Epoxy surfboard repair kit. Polyester might eat a hole in your Polystyren blank!
For WAVE-, WIND-, KITE-, and SUP Surfboards
