West System G/Flex liquid epoxy is a toughened, versatile adhesive designed for permanent, waterproof bonds on fiberglass, ceramics, glass, masonry, metals, plastics, damp and difficult-to-bond woods. G/flex epoxy is resilient enough to bond dissimilar materials and flexible enough to absorb the stress of expansion, contraction, shock and vibration.
Available in liquid and thickened formulations, liquid G Flex 650 is a two part (resin and hardener) mixed at a 1:1 ratio. G/flex 655 is also a two part epoxy adhesive, but contains a thickening agent.
Note: 8 Ounce G Flex 650 kits are available in 2 formats: as 4 ounce resin and 4 ounce hardener kits (650-8), or with accessories that include 2 mixing sticks, 2 syringes, 4 mixing cups, 406 Colloidal Silica, 1 pair gloves and 4 alcohol pads (part number 650-K).

I need to repair a piece of Teak. It is a cap which fractured clean from a dining room table leg. Would G/Flex be a good glue to use (on Teak wood) ?

2012-08-20FRANK BERRONES: I am sorry I cannot help you with that. We used it as an adhesive to clad wood with copper sheeting.
2012-08-20ROBERT SPANGLER: I JUST PAINTED MY BOAT, I USED G-GLEX ON EVERY RIVET AND SEVERAL CRACKS AND PIN HOLES, I JUST LIGHTLY SANDED IT AND PRIMED, THEN PAINTED OVER IT. IT IS EARLY, BUT LOOKS LIKE ITS DOING GREAT
ROBERT
2012-08-20BRIAN RUSSELL: Epoxy generally accepts paints just fine, as long as their surface is sanded to remove the gloss. I would test a small area or better, a sample before jumping in whole hog. Give the epoxy at least 3 days, better is a week, to fully cure before sanding, priming and painting.Then let the paint cure well. test with some sticky tape. If the tape pulls the paint away easily, then the bond is no good and you need to rethink the method or materials.
Hope this helps

2012-08-12A shopper asked: will this adhere to polyethylene and or polypropylene?
+Expand Answers
2012-08-13RODNEY KIRTSINGER: I have only used it on metals. I would guess that the epoxy might not adhere to polypropylene because propylene has such a smooth surface. You need to do a test, if it does not work- at least you will have some fine epoxy for other products.
2012-08-13JANE SEA KAYAK CAROLINA: You should find the answer in the package leaflet, or go on line to read about G-Flex
2012-08-13PAT OTTON: Yes, Please see GFLex instructions for proper surface preparation. It may involve flame treating. I have had success using GFlex product to bond with both polyethylene and or polypropylene.
2012-08-13DENNIS BRINTON: I bought it in May, but have not used it yet. It was for repairing my camper. The rot was more extensive than I thought and took longer to cut out. I planned to use the West System G/Flex to re-attach the fiberrglass body panels to new plywood. I'm not at that step yet. I'm sorry I can't offer you more assistance.
2012-08-14Kevin Gardner: I used it to adhere polycarbonate to fiberglass and it worked very well. So I suspect it would work with PE or polypropylene as well, but have not used it to do so. I sanded the polycarbonate first to provide a rough surface.
2012-08-14PETER BACH: I have not personally used G Flex to repair plastics, but, West systems has instructions to repair plastic kayaks, which I believe are made from polyethylene.
You tube has several videos on the subject. I would suggest looking there.
Good luck
2012-08-14JOE PARKER: It was the only thing that worked to patch my sit on top kayak which I believe is polyethylene. So far it has held up great. I followed some hints on the web for prepping the surface and then just followed the instructions.
2012-08-15DAVID BIRNBAUM: I have an old plastic kayak that is rotomolded but not sure which poly is used. I took a chance and the G/Flex was wonderful. It stuck and sealed completely and it's flexible as advertised. A local Kayak shop told me about the kit.

+Expand Answers
2012-02-14STEPHEN EZZELL: I bought the 8oz. Kit for building a graphite push pole and have been surprised at how far it has gone for me. You probably could get by with a couple 8 oz kits but for a little more I'd get the 32oz. You' ll find a ton of uses for what u have leftover
2012-02-14NATALE MARASCO: 32oz kit will work.
2012-02-26Leslie Bell: Hi John,
That's a tough question to answer percisely. I had a 14 footer myself some years ago. It was a nice economical boat. I like it. But back to your question. I am thinking back to how many seams it had. The stem and the keel, and around the stern for sure. It would also depend on how much was absorbed into the seams rather than just coating the surface. The directions come with the kit so I won't go into that. I would estimate that you would need one kit for sure because you will need the syringes and gloves.But you will need at least one more set of 4oz. bottles but not the kit. So basicly I would get oneG/Flex kit and at least another set of 4oz. bottles. If you have time to see how far that goes (total Mixed would be 16oz. or a pint) and then only get another set of bottles if needed but then you would have to consider the extra shipping charges. You will also need a propane torch or heat gun and I prefer to clean up with isopropol alcohol so a bottle of that and pipe cleaners to clean the syringes. Cheap plain papers towels (roll) is helpful too. Just follow the instructions and I beleive Jamestown has a video too, and it is easy. Just go slow and work with smaller quantities at a time and if you miss a leak or two you can always go back and fix those too. It works. Good Luck and good boating

2011-12-28A shopper asked: Does G Flex dry as clear or amber color?
+Expand Answers
2011-12-28NATALE MARASCO: light Amber
2011-12-28ROBERT DZURICKY: When mixing the clear & amber components, the amber color lightens a bit but it's still amber. When hardened, it retains the same amber color it had when mixed.
2011-12-28JOHN ROUNTREE: The product dried with amber color. Great product to work with.
2011-12-28MICHAEL TIMMER: it dries an amber color from direct experience. West systems says the thickened version of G/Flex is darker.
2011-12-28LES WILSON: The GFlex is clear, it appears amber over kevlar, or white when silica is added. Good stuff Man! But clear and super.
2011-12-29Leslie Bell: Dear shopper;
G/flex does indeed dry clear. I have varnished over it with Interlux Schooner varnish with excellent results. If you intend to varnish over, I would sand at least with 180 grit or 220 grit but would not use 320 or higher until at least after two coats and then would use 320 grit. I am testing a peice with prekote from interlux and the 1st. coat seems to have worked well even though in the data sheet it recommends not to. It recommends using primekote but in their boat painting guide they recommend prekote. Seems that there is some ambiguity when using a finish primer over a clear epoxy, thus the test peice. Primekote is a finish primer for the two-part epoxies and is not compatible with a one- part such as brightside. I have used g/flex extensively and have used it blended with 105/207 clear and have found that I like the results. The blended viscosity and wet-out charateristics are proportional to the ratios of the blend.
good luck and do not be afraid to test some peices before actually doing the real work.

2011-12-09JANE SEA KAYAK CAROLINA: No. The folks who make G-flex should be able to answer your question, and give advise as to the best procedure for a successful repair.
Cheers,

2011-12-30PETER OBRADOVICH: This is the first time I used G Flex from West Systems ,But the other products I have used from west have preformed well. I guess my suggestion is to check the suggested uses from the manufacturer and see if they meet what you need in the area of flexibility, and how much movement the tank you want to repair will be subjective to.You may have to use some type of material to put on this crack that is soaked in the epoxy and then laid on the crack for a better seal,such as ( rubber, fiberglass cloth,etc.
2012-01-28Leslie Bell: It would be more helpful if you were specific about what material the holding tank is fabricated of. But I have found through extensive use of G/Flex that with proper preporation that it will work very nicely. Assuming that it is plastic, it would be difficult to say what kind unless you could find a recycled emblem. This would indicated which type of plastic e.c.(ABS, PVC, HDPE, LDPE), all of which would need an anicial wipedown of at Least 70% isopropyl alcohol ( I use 91% as a solvent and clean up for G/Flex as well). Then it is necessary to flame treat, which is explained with the guide you will receive on purchase. If metal, it will work well with aluminum or steel, which of course needs remove corrision and loose surface material. At any rate I would back this repair up with fiber glass and would use colloidal silaca that comes with the repair kit. Also something to consider. There is a reason that the crack occured. Most likely vibration and load. Consider these factors also in the repair to prevent further malfunctions. Good Luck, and feel free to experiment. A little extra weight will not be significant and it would be hard to go wrong.
Leslie
2012-01-28TED MROZEK: I did not use it to repair a holding tank. I did use it to repair a piece of ceramic which has a great deal of sentimental value. It worked great. I also used it to repair a few broken pieces on the train set. Both plastic and metal pieces. Worked great.
2011-11-13A shopper asked: I am repairing my Kayak which has two 5" cracks which are 1/16" wide.
should I use G/Flex 650 or 655?
Thank You
Mike C
+Expand Answers
2011-11-14ROBERT DZURICKY: I may not be qualified to answer this since I've never used 655 & my application is completely different (I make custom pool cues).
However, in the testing I've done comparing 650 to West System 105/207, System 3 Clearcoat and several 24 hr epoxies, the 650 is just as strong and MUCH more flexible. Most of the others would crack when bent beyond maybe 20° or so but the 650 was good until almost 90°. I think if you sandwiched your crack between a few layers of fiberglass cloth & worked in some 650, you would have a repair that would last forever.
Again, I have no experience with 655 & really don't know the differences between 650 & 655. But I can assure you that 650 is strong & flexible & sounds like a good fit in your application.
2011-11-14ROBERT DZURICKY: Upon checking the differences between 650 & 655, it sounds like 650 is the best option for you, especially is you sandwich the crack between 2 layers of fabric. I would not suggest simply trying to fill the crack.
2011-11-15THOMAS MANI: Haven't used the 655, but the 650 should work well. Get an adhesive filler like West 406 and follow directions. Be very cautious with the product. Use protective clothing, eye protection masks and work in a well ventilated area. Be sure you can remove protective gloves without getting any of the resin on your wrist. Try to apply so you have little or no sanding to do.
2011-11-26Leslie Bell: Mike C,
The basic difference between the 650 and the 655 is that the 655 is pre-thichened with 406 colloidal silaca. This of course is a mere convenience as it is already mixed. But since you will have quite a bit left over with just a small repair as that, I think I would purchase the 650 kit. It has more uses in that not always would you use the pre thichened consistancy. For a different use or repair, you might wont to use it unthichened or maybe only slightly, such a ketchup, mayanaise or peanut butter. You will find that although it appears in the two tubes or bottles that it is not all that much, it actually is a full 8oz. when mixed, and really does go along ways. Thus with all these considerations I personally would buy the G/Flex 650 Kit. It has everything you need for this repair and others as well. I am sure you will find other uses and the rest will not go to waste. Just follow the directions for this repair in the kit. If you do follow the directions to the letter and mix small batches and work methodically you will have a very successful and reliable repair.
Good Luck and happy paddling

I holed my royalex canoe seal launching into a rock. I knew normal epoxy resins would be too stiff to last for a long time. Canoe shop owner suggested g-flex. I used 2 layers 6oz. fiberglass and the g-flex, repair done in the low 30's for temperature, certainly not ideal. Patch is holding well, and is not stiff like other resins.I like how this stuff flexes, and it's tough as well.

I have an old wooden ketch. I glassed the decks with 105/206 and biaxial cloth with mat. The glass extended over the top of the stem 9end grain). After a year or so, the glass separated from the end grain. I removed the old glass, drilled some holes in the end grain, filled the hole, glassed over with several layers of cloth (Gflex os too thick to soak into biaxial). Three years and is still good.

Comments about West System G/Flex Liquid Epoxy Kits:
I have three Pungo kayaks that were damaged from dragging them. The rudders were worn down and caused leaking. With kayak right side up, open the rear hatch, use 80g sandpaper to clean the surface inside and vacuum. Flip it upside down, clean the rudder area. Apply duct tape over the hole, flip right side up again, put a couple of small wood blocks to raise the front end angle so the epoxy settles and cures into the desired area. Pour a 50/50 mix of the epoxy into the back rudder area. The tape prevents leakage. Let dry overnight. Flip kayak over, use tape to reform the rudder creating a pocket for the epoxy. Set the angle again. Pour same 50/50 mix into pocket. Let dry overnight and you should be all set!
