A GUIDE TO WATERPROOFING FIREWORKS
With the uncertainty of the Great British weather, those who want to light fireworks regardless of the climate may wish to waterproof their fireworks. With just a little preparation, fireworks can be successfully fired in all conditions, and here we describe the best methods for waterproofing.
Barrages, Compounds, Large Fountains, Roman Candles and Mines - Professional display teams waterproof fireworks using pallet wrap and this is very similar to cling film which can probably be found in most homes up and down the country. Firstly, you will need to expose the fireworks fuse, and this is often a simple case of removing the orange fuse protector. Having located the fuse, some like to run Sellotape along both sides of its length and this measure, although not always necessary, will add additional protection to the one area most susceptible to damp. Note that larger barrages and compounds may have a reserve fuse, and this should also receive the same treatment.
Placing the firework on an unrolled length of cling film, (or pallet wrap if you have it), the idea is to completely cover every surface of the item, much like wrapping a present. Applying enough pressure to stretch the film slightly, you should rotate the firework until the entire outer area is protected, whilst being mindful to leave wide overlapping borders if multiple passes are needed to cover larger sides. At this point, it is necessary to highlight or note where the now completely protected fuse is so that it is easily found when you go to fire the item.
We always recommend placing fireworks on a firm surface and if you plan to place fireworks on a grassed area remember that damp can remain in soil for long periods of time and does also rise. In these instances, a wooden board should be placed under each firework and will offer both extra protection from moisture whilst also preventing recoil.
Do not worry about removing waterproofing prior to ignition. You will find that a fuse is easily lit through cling film and effects will effortlessly launch through this protective layer. The only fireworks which do not apply to this rule are our Fire Snake and Nitro 100 shot missile batteries. When using pen-lid type cakes, film and their clear plastic lid, should be removed prior to firing.
Some prefer not to use cling film, but instead favour plastic bags. When using plastic bags you will need to prepare fuses in the same manner as above, and it is advisable to purchase clear bags so that fuses are easily found once covered. Placing fireworks within a bin liner, or freezer bag for smaller items, you can simply tie a tight knot to seal the protective bubble and this will shelter fireworks from rain with very little effort. When securing fireworks, you should be mindful not to tear its plastic covering, and some like to place a second bag over the firework once it has been placed.
You may find that larger fireworks do not fit within a bag, and in this case you should use the cling film method mentioned above.
Rockets and Wheels - Rockets and wheels should never be wrapped in film, but instead it is advisable to cover them with bags. These bags will need removing prior to lighting and, as a result, it is not essential that the bags are clear. You may want to consider leaving fuses within their protector for extra insurance and, prior to firing the device, both the protector and bag can be removed in the few moments before ignition.
Selection Boxes - With selection boxes, and other small fireworks, requiring minimal preparation, we would advise that items are placed within a waterproof container from which you can remove the fireworks one at a time for lighting. Fireworks are damp resistant for a short period of time, and it is only necessary to try and shelter the fuse in heavy rain.
