This can easily be mounted to wet surface. By pressing the epoxy into the rock it will harden onto the imperfections on the rock. Feel free to let us know if you have any further questions!
The only difference between those two models is the size of the container. The 104.76 is the larger 400g container.
104.75 Coral Gum Instant 120g (4.23 oz)
104.76 Coral Gum Instant 400g (14.11 oz)
Really well made and optimized putty By Justin on 12/28/2016Justin would recommend this product to a friendI was a bit leary with the price, ordered my first small tube and loved it. Albeit it the price is high, it works great, turns hard rapidly and doesn't crumble like jb weld does half the time. I likes it so much I just ordered the big tub to do some rock repair.
Great product By Jason P. on 12/10/2016Jason P. would recommend this product to a friendEasy to use. I use it for attaching frag rubble to my main rocks. I like to use it only for smaller jobs. Definitely will purchase again.
Super putty but not really "adhesive" By George on 8/13/2016George wouldn't recommend this product to a friendThis two part putty is easy to mix, doesn't leave a purple residue on your hands (dry your hands before use), doesn't "cloud" the water and cures quickly to a slightly rubbery consistency. It isn't sticky at all, so it won't work well as an adhesive (as some of the poor reviews have indicated). I use it to create a platform in irregular rock surfaces to allow placement of a frag....then glue the frag to the platform with CA.....this composite technique works super well! I've used this to place larger colonies and small frags and both work well.
The color is purple but slightly lighter than "corraline purple" so it is best to minimize the visibility of the platform....still looks better than a big wad of CA to me.
Works well but is expensive By Clint on 5/16/2016Clint would recommend this product to a friendI really like this stuff but man is it expensive. I went through the 120 gram container mounting 4 frag plugs to my live rock.
Easy to mix, but ineffective By KC on 1/19/2016KC wouldn't recommend this product to a friendWell, I had great hopes for this product... and it does well if you don't put any pressure on the bond. Very neat and clean tho'. I have to recommend E-Marco-400 which easily reconnected my Real Reef Branch Rock which arrived shattered in many pieces. (BRS shipping department sent the rock with a 20 lb. bag of sand-UGH!!) Yes, E-Marco is a little messier, but forms a strong, solid bond in 20 mins. I tried reattaching the many pieces with both products. While the Coral Gum has a near instant bond, that bond does not hold - so no rock to rock use. It might work better if you were trying to cement a frag down into a hole... but not flat to flat surface grip.
Great Product By Nate on 11/26/2015Nate would recommend this product to a friendI have just tried this out for the first time today and was really impressed with it. The gum is super soft and easy to mix and work with and doesn't leave a mess on your hands or in the water. The coral stuck at least as well as any other epoxy that I have used. Another thing that I really appreciated is that it didn't seem to negatively affect my skimmer like other epoxies.
Awful By Vaesive on 10/23/2015Vaesive wouldn't recommend this product to a friendTried Coral-to-frag, frag-to-rock and rock-to-rock bonding the epoxy doesn't stick. If you somehow do get it to stick, it easily pops off with very little force. Do not recommend.
No mess, works great! By James on 8/15/2015James would recommend this product to a friendThis stuff is awesome! Mixes with wet hands, no mess, not really any smell, and definitely holds. Just make sure you mix it really well with your fingers, and like some people have said it is epoxy not glue. You do have to press it into something (the rock) really well so it can harden and stay. If not it will not do what you want it too.
No Mess By JEMM55 on 7/14/2015JEMM55 would recommend this product to a friendNo Mess
Works Well By Q on 1/10/2015Q would recommend this product to a friendI bought this to use on my aquascape. I used it create tree like structures with the rock, I did use acrylic rod in the middle but used this to hold things together. I can say that it works. Ultimately, it is epoxy and not glue, so if you want it to stick to rock, make sure you push it into the rock well.
good and easy 400g only By Ryan on 12/29/2014Ryan would recommend this product to a friendTwo part 400g mix that we like lot here at ReefDVMs. Dont care for smaller size one works only so so. 400 is different then 104 by the way
Simply the best By Bert on 7/3/2014Bert would recommend this product to a friendFor me, this is simply the best. Zero smell. It works outside my tank or underwater. My skimmer does not go nuts as is the case with every other epoxy I've tried.
To attach a frag, I generally put a dab of BRS thick glue on it, followed by a small bit of mixed "gum", with another small dab of BRS thick glue on top of that. In it goes to my tank, a quick press into place with a slight turn. Hold for a few seconds, and it's there.
The only disadvantage I see to this produce is the price. Definitely on the high end!
