Big Ding Epoxy & Polyester Surfboard Repair Products

We – Tao and Felix – know each other our whole lives. Back in the days, we began surfing at Munich’s inglorious downtown river wave – “the Eisbach“.  As surfboards get frequently crashed at the rough stone walls of this urban surf spot, we had the idea to produce our own surfboard repair kit. In 2011 we rented a garage, ordered all the material and assembled the first hand-crafted kits. We knew, to be successful the most important thing would be to use the best available quality ingredients and to provide the kits at a fair price. Finally, we packed everything in a screw-lid box and named it BIG DING. Today the production is outsourced to German partners including Caritas – a social factory in which handicapped people get jobs for packaging. We are proud to say that our products are not imported from Asia. BIG DING repair products are available in surf shops all over Europe.



Typically surfboards are measured in inches. The length is measured from the nose to the tail. Choosing the length of the surfboard is dependant on your size (weight, height), board type and waves conditions you wish to use the board for.


The widest point of the surfboard is measured from rail to rail. Generally the wider the surfboard the more stable the board, while a board with smaller width maintains better speed and performance.


Surfboard thickness is measured from the top deck to the bottom. The thickness again has a bearing on the board’s performance. Professional surfers will tend to go for the thinner boards as they are lighter and offer better performance.The thicker boards are stronger and because there is more foam under the surfer the boards are more stable.


The bottom curve of a surfboard. Generally the more rocker the surfboard has the more loose (manoeuvrable) the surfboard will be. Where the flatter rocker surfboards will be faster, although they will lack the looseness. The nose is the tip of the surfboard, the nose can vary in shapes and size. Basically the thinner the nose the more response the board will perform, while wider noses are better for stabilization.


Used to increase the strength of a surfboard, a stringer (normally made from wood) runs down the length of a surfboards (typically in the centre of the board from the tip of the nose to the tail).
Boards built with Epoxy, Carbon Fibre and soft boards generally don’t have stringers.


Generally heavier surfers require larger fins to hold the waves better. Although if you prefer to ride a looser (less hold in the waves), smaller fins would be a better option.


Fin configurations have an effect on the ways your surfboards perform.
The following are some of the more common fin configurations.


The single fin was the original fin configuration for surfboards. Based on the idea of the sailboat keel. Single fins are added stabilization and control on the powerful, larger waves, although lack manoeuvrability


Are great for small waves, being fast and manoeuvrable, but when put into tight spots on larger waves, they become hard to control. Popular with Fish surfboards.


Widely recognized as the standard fin configuration, the thruster answers the shortcomings of the single fin and the twin fins configurations.
The thrusters give you stabilization, control and manoeuvrability in all types of surfing conditions.
This concept was the brainchild of Australia’s Simon Anderson


With four fins in the water, Quads boasts an extraordinary amount of holding power in larger surf.
You may think that having four fins would sacrifice speed by creating more drag, but this is not the case.
The both sets of fins are working together on the rail, which makers believe they creates less drag than a board with a centre fin.
The manoeuvrability isn’t sacrificed either, with fins directly under your back foot, the quads are very responsive.


Similar setup to the Twin Fin, although smaller (low profile) fins are generally placed wider (closer to the rails) on the surfboard.
Popular with Fish and Egg / Retro surfboards.
