Epoxy has rapidly become the tool of choice for boat builders! It is a glue/sealant that is used to tie together all sections of the hull, as well as to have a waterproofing standard. There is a wide variety of various boat building epoxy materials now as with all these days, but polyester and epoxy resin are the two primary forms used in boat building. like this
Polyester is the cheaper of the two, but not ideal for usage on timber, so you can almost only use epoxy resin of some form or another while constructing a wooden hull. Epoxy resins are also less brittle and have a superior propensity to bind to timber, meaning they have a superior capacity to cover holes.
Epoxies do have their disadvantages, though. The first point to note is that they are difficult, because this suggests that they are fragile. You can combine them with chemicals that will make them less so but when you do this, the issue is that the intensity will also decrease. It is also better to stop using them on something that, if at all necessary, wants to flex entirely.
Under extended exposure to UV light (sunlight), epoxy can either deteriorate, so it will need to be reapplied frequently, or covered with overcoating. Also a thing to remember here is that the epoxy soaking in would avoid any degradation of the wood such as oil or moisture and this will result in the coating peeling off. Therefore, make sure that the surface is clean and clear for the optimal outcome before adding the epoxy.
Like for other products, you get what you pay for with epoxies, and it is costly for the highest performing marine epoxies. Cheaper ones can be bought, although the less you spend, the more possible it is that the resin has been diluted in any way. Whatever it’s been mixed with, this would decrease the overall consistency, whether it’s with a non-solvent thinner or inexpensive filler.
Therefore, my suggestion here is to choose a high performing, well-known ‘marine’ epoxy brand. In the near term, it might be more costly, but it would turn out well in the long run.
As with boat building epoxy, the final point I want to draw your attention to is that of defense. Any people might be allergic to it so it is often a safe idea to monitor it before embarking on some epoxy project. Better than coming up with a rash, getting sick and not being willing in the final stages to finish the voyage.
The key source of skin inflammation is obviously the hardeners. It is best, though to prevent all eye interaction with the products and use plastic gloves and a breathing mask while handling them at all times. Clean it off as quickly as possible if you have some epoxy resin on your hands.
