MAX Bond Low Viscosity Marine Grade Epoxy 4 Boat Building & Repair of Hulls,Decks,Transom,Trailer Floors -Salt & Fresh Waterproof, Impact Resistant, Extreme Toughness, Strong Glue,1 Gallon Kit

This epoxy is very easy to use. It is an easy 50/50 mix, so it is virtually goof proof. It takes about 24 hours to cure, so you have plenty of working time if you need it. Since it has such a long "open time" it can be a bit messy as it levels itself on your work surface, so you may want to put whatever you are working on onto an old shower curtain to keep your workbench from being covered in rock hard epoxy. HOWEVER...if you do that, make sure to take the piece off of the curtain after about 8 hours or the shower curtain (or visqueen, or whatever you are using) will become a permanent part of your work piece. There are some products that are cheaper on Amazon, but I needed something that would withstand the rigors of a boat transom more so than the epoxy that is meant for furniture building. This is marine grade epoxy, and, although a bit pricey, a good value.

I purchased this epoxy resin for a project that quickly turned money pit. I had found the deck was cracked and was previously repaired with what appeared to be some kind of auto body filling compound. I initially started with West. But the price of the West system products and the amount or material needed for this repair made me look for an alternative.Just so you know I have decided to be very critical on every review I do here on Amazon now. I have been screwed with really bad products with glowing reviews. So her goes.I do not do fiberglass repairs, and am a compete novice relying on information off of the internet. However, using this resin I was able to make repairs that looked and felt professional (to me). It was slightly harder to sand than the other products I used. It was hard but seemed a bit more elastic and would grab the paper, if that makes any sense. However by the time I was finishing my major repairs, it was the Max Marine epoxy I was reaching for as the repairs made to my really spongy deck were absolutely rock solid. I used about 3/4 of the gallon to make the repairs on my deck.Pros: Nice working time even for a novice. It is that happy medium that allows you to get the stuff mixed, applied, and sorted before it goes off. Some of the repairs I was making were large. The deck cracked clean through requiring me to work both sides... This allowed me time to get what I needed to get done before it would start to gel up on me. I live in California and some of these repairs were made during the summer with heat in the shade around 90 degrees. I would get about 10 to 12 minutes working time at these temps. The resin would stay where I put it for the most part. I really liked that.The repairs were absolutely solid. 24 hours after each repair I would walk onto the deck and find it feeling like new again. Sand it, shape it, and think wow, that looks a lot better than I thought it would.Cons: This is a 50/50 mix and I had to purchase mixing cups in order to get the measurements right. Slightly harder to sand. Using the cups I sometimes poured too much resin and would have to mix a bigger batch or pour it back in. The pumps were nice with other products but I always worried the ratio was off due to air in the pump. None of this was really a con, just being as critical as I can be. I used paint measuring cups.I would buy this again and use it exclusively I think. If there is some issue in the future I will get back on and update this review. I hope this helps.

Takes as much as 24-36 hours to fully cure. Of course that can be an advantage but would slow progress on some projects. I used it to patch my rotting Victorian porch. It seems excellent for that. Hard and waterproof. Deck paint adhered well on primer over epoxy. After a couple of months of freezing, snow and rain, it seems fine though under water part of the time . It is fairly thick when mixed , but is still liquid and will self level or run through holes larger than a couple of mm's. Now editing in March, several months after previous review. I did some repairs on this pine porch deck with an exterior spackling compound. It has flaked, swollen and shed the paint. This epoxy so far seems to have truly fixed the rotted cracks. Paint still on!

Very good Epoxy, easy to mix and hardens and fastens great. Good price will buy more, when I need it..

Item came in a secure package with the lids taped. Good, easy to follow instructions printed on bottles. Worked as advertised.

I had 3 customers I was working on repairs for in the same week, so, I was really under the gun. I ordered this product while at one customers house to inject into some beams to strengthen the area that was dry rotted. The description nor the pictures showed they were 1/2 gallon. Oh they do now, but not when I ordered. Long story short, I had to drive 50 miles round trip to get more epoxy. Same quantity 1/2 the price, uv treated, better setting time better results. Remember, for half the price. There are better quality products on the same page of Amazon that you are looking at, Marine grade, 1 gallon kits in the $50 to $60 price range, buy one of them

I'm building a boat and this product is what holds it together.

Great price, was delivered before expected. Worked well. Cleans up with vinegar or acetone. I appreciated extra working time when laminating two peices of plywood. Plenty of time to mix,apply and clamp. Appx 10min. Epoxy set up in about 20 to 30 min. @ 67 degreesI did notice some entained air dureing mixing. Worked the bubbles out during application.
