TotalBoat Fathom Deep Pour Epoxy Resin - 1.5 Gallon Casting Kit, 1-3" Pours

I love this resin! It's great for doing flower preservations. No need for multiple pours. Just one small one to set everything in place and one more to fill the mold about 2/2.5" deep. It is a slow cure so don't be alarmed. Their website has great directions and a wealth of information! It's crystal clear and virtually no micro bubbles. A heat lamp or a room above 80°F will speed up the curing process but it's definitely not necessary. Just wait out the 3 days. You won't be sorry. Very low oder (to me at least). Not good for pours less than 1" it'll take too long to cure but it will still work.

I'm quite impressed by this product. It takes a long time to cure (up to a week to get fully hardened), but it will be quite hard at that point. It has a low viscosity (similar to vegetable oil), which when combined with the long cure time, means that most bubbles have time to work their way out before they're trapped. That said, like all epoxy resin products, a vacuum pump is a good idea and can dramatically reduce the number of defects you'll find after it's cured. My suggestion when working with it is to pour in thin layers; I aim for no more than 1 inch thick, and generally try to keep it much less than that. That makes it easier for the bubbles to reach the surface, and gives you a chance to look for defects before they become a serious problem. The long cure time also means that you don't have to rush the mixing; at room temperature it'll still be quite runny even after an hour our so. That should give you PLENTY of time to ensure that that you've completely mixed the components.Since my project isn't finished yet, I can't speak to the long-term durability of the cured resin. Only time will tell if it is UV stable, or otherwise good in that way. That said, it is significantly harder than the bar top epoxy I used on another project (which was a different brand). My suspicion is that it will reasonable durable under normal use, such as for a river table.A final note on using this product. Good mixing is KEY. I use old yogurt containers that I've thoroughly cleaned out and dried, which lets me inspect the mixing to make sure it's complete. Use a small kitchen scale to weigh the components as you pour them into the yogurt cup; this is more accurate than trying to measure by volume. The instructions say to mix Part A (the resin) to B (the hardener) in a ratio of 1:0.44 by weight. Set the scale to work in grams, put the empty yogurt container on the scale, and tare it out. Pour Part A in first; this will be about 2/3 of the total volume, so leave enough room for Part B. Once you have enough, weigh it and pour 0.44 times that amount of Part B in. At this point, the contents will look opalescent or milky; that's how you know if you've mixed it enough or not. Start mixing as the instructions direct. Look for streamers in the liquid that still look opalescent. After you can't see those any more, continue mixing for another 2-3 minutes. At this point, it should be ready to pour. If you want to add in any dyes or other additives before you pour, now is the time to do it.

Be ready for a long hardening time. Other deep pours I have used were somewhat quicker but I like the slow set-up of this product. Very few bubbles!

Epoxy is great! Make sure to keep it at a proper temp. Will cure at 40f but will make the process longer by quite a bit (around 2 weeks). I poured 2 inches at once with no issues. 5/5 epoxy, best stuff out there, no doubt.

One of the best epoxies I’ve used! Good price!

Love this deep pour epoxy! I couldn’t get over how FAST the bubble release was on its own. Usually I’d need it to sit much longer to wait for bubbles to rise and pop. Also, its long working time came in handy when I accidentally mixed epoxy too early for the second layer. Love the results!

I have been working with epoxy for many years and heard great things about this one. It was extremely disappointing that this wouldnt cure at all. I tried a few times thinking it was me possibly missing a step but every project I tried, it wouldnt cure at all. Even after 12 hours it was exactly the same as when I first poured it.

No epoxy is 0 tiny bubbles but thats why you use dye. This stuff is very low bubbles with a longer working time than most other brands. My favorite deep pour epoxy.
