CJ NELSON EPOXY MATRIX SURFBOARD BLANKS

Each EPS fused cell blank is built utilizing materials and construction methods that deliver precision and consistency board after board. The proprietary multi-component fiberglass stringer system is added to the hand-tuned EPS core to provide longitudinal strength with controlled flex in the nose and twist in the tail.

The EPS blank with stringer system is reinforced with hand laminated fiberglass, which is then encased and bonded to a high-density foam shell using epoxy resin to form the completed blank.  This blank is then cured in a precision mold that locks in the same rocker and rail profile for every board – the only way to make every board a magic board.

Our blanks have more materials and labor than many finished surfboards, but this is just the beginning for us.  Once completed, our blanks are then hand laminated using combinations of fiberglass and XEON Fiberglass, or Carbon Fiber to yield the finest epoxy constructions in the world.

SHAPES

CJ Nelson partnered with Australian Shaper Ian “Chissa” Chisholm to design longboards and fun shapes at the highest levels of quality and performance. Chissa has been hand shaping and building traditional PU boards in Torquay, Australia since 1995, and takes great pride in his craftsmanship. Combined with CJ’s talent in the water and board knowledge, these shapes are tried and true for performance and style.  Traditional PU shapes have been tuned to take full advantage of the advanced materials and characteristics of this new EPOXY MATRIX technology. 

CONSTRUCTIONS

CJ Nelson Surfboards are designed in four different constructions. See the technology graphics below, which can also be viewed on each surfboard product page.

LAMINATIONS

  • XEON Fiberglass
    • This is either 4 oz or 6 oz fiberglass that has the pigment in the fiberglass cloth. The colors in these laminations come from the cloth itself and are laminated using clear resins
    • Flex characteristics similar to fiberglass

  • Fiberglass with Opaque Resin Tint 
    • This lamination uses regular fiberglass and opaque pigment in the resin for color - very traditional style of lamination in this case
    • color pigment is mixed into the resin during lamination…in the case of the “Clear” board, the pigment is opaque white
    • Flex characteristics of fiberglass

  • Texalium (Silver)
    • This material is 6 oz fiberglass that is infused with super-fine aluminum powder which gives it its silver appearance
    • This material results in a slightly heavier lamination due to the weight of the aluminum and the 6 oz fabric takes a bit more resin
    • Flex characteristics like fiberglass, but since 6 oz, a bit stiffer than 4 oz laminations

  • Carbon Fiber
    • 6 oz Japanese manufactured carbon fiber cloth.  Super good quality…’nuff said
    • Flex characteristics….slow flex and fast rebound…these boards need a few sessions to “break them in” and limber them up, but are super responsive/snappy due to fast rebound rate

  • Carbon Fiber / INEGRA blend
    • This is a 50/50% blend of carbon fiber and INEGRA (ultra-high molecular weight polyethylene)
    • Fiber bundles in this weave are flat (gives the crazy 3-D look due to how the light reflects off the fabric)
    • Flex characteristics in between carbon fiber and fiberglass


PROPER CARE OF YOUR CJ NELSON SURFBOARD          

High quality construction and advanced materials translate to strength and durability that outlast the majority of surfboards you’ll see on the racks. Take proper care of your CJ Nelson Surfboard to keep it in beautiful condition for even longer. Follow these basic tips.

  • Stash your surfboard in a bag when you’re in transit. The extra protection of foam and material will prevent dings and damage while packing your car or carrying your board down the stairwell.

  • Always keep your board out of the sun, and avoid keeping it enclosed in your car.  On hot days temperatures inside your car can exceed 150 degrees, which can damage any EPS core board. This is particularly important with boards that are darker in color which can absorb heat quickly when left in the sun to bake. 

  • Keep it clean. Rinse off the sand and salt before putting your board in the bag. This will help keep sand and debris out of your board bag and reduce the risk of scratching that beautiful finish.

REPAIRING YOUR CJ NELSON SURFBOARD          

Life has its ups and downs, and it seems inevitable that all surfboards eventually get dinged and need repair. If you ding your CJ Nelson epoxy surfboard it’s no problem. Our boards repair using the same basic methods as any epoxy board, and that includes models with carbon fiber. Here are the basics:

  • If you ding your board in the water, get out and avoid extended exposure to water. All foam boards will absorb some water once dinged, and you should try to minimize this.

  • Let you board dry out if you have taken on some water, so that you don’t trap water inside your repair, and so that the resins used in the repair don’t react with the water.

  • USE ONLY EPOXY RESINS IN YOUR REPAIRS! Polyester resin chemistry reacts very strongly with epoxy /EPS chemistry and can severely damage your surfboard if you use polyester resin.

  • Use regular fiberglass cloth in your repairs, even if going over carbon fiber. Let the resin cure completely, sand and polish, and you’re good to go. Better yet, take your board to a professional ding repair shop to make sure repairs are done properly and your surfboard is returned to as close to new condition as possible.
