How to Repair A Cracked Flood Tray

[JuneBugJoe]

Looking for the best method to fix a cracked flood tray. Has anyone tried the JB Welds "Water Weld" that is suppose to be ok for potable water situations. If not, is there a caulking or sealant or some type of plastic weld that will med these cracks?

Thanks

I have used jb waterweld on numerous surfaces with success. Just make sure you take some sandpaper and scuff the area around the hole so the waterweld will hold to it.

Is this water potable safe? I will look into it.

Thanks for the feedback on the JB Water Weld. Ill try it out....

I have two trays, a 4x4 and 4x8 that I got for Free!! Only thing is someone decided to run a forklift through the sides of them... Slight damage and not much plastic chipped away from the tray so I was more than happy to try and repair them.


Going to keep this thread updated on the repair and also results after grows of prolonged use.

There are a few silicone products made that are safe for fish tanks. Supposedly they dont leech anything dangerous into the water.

Another product that came to mind is Marine Tex.

FLEXSEAL LOL.. works like a fucking champ.. a friend of mine bought a broken ez cloner.. and it had a crack with missing plastic . big enough were it was over an inch by 2 inches of missing plastic.. we put tape on the inside.. and flexsealed the outside.. we did 2 coats to be sure nothing would leak threw.

had to do some sanding just a lil to get it rough enough to stick well enough for me to trust it.. but this stuff works great.. we did the outside so the inside remained clean.. nothing to leach into the water.

been like 2 months of using the thing.. not a single drop has came out of it.

if you can get geo-cell 2300 or 3300 its the best thing to use for your situation ime.
you don't want anything that sets up hard,
with flexing of your tray it has a way better chance of cracking.

geo-cell stays soft and flexible for years, like 7-10 years.
layer it with some fiber glass screen, especially if there's a hole and you should never have another prob in that spot for a decade.
you can get geo cell 2300 at your local roofing supplier..
if you cant get geo-cell go to a vinyly siding alum patio supplier and get solar seal.

one last **very important* thing to do,
if you have a crack you need to drill a hole, 1/8" or 3/16" will do,
and drill it just ahead of it or right on it if you can.
sometimes you can't see the end of the crack, get a magnifying glass and mark it.
cracks can/will keep running regardless of sealants

good luck!

Ive used devcon 2 ton epoxy with good results, sets up a bit stiff tho. Envirotex epoxy may be another option, it more pliable. Same stuff they use to coat bar tops. Sand the surafce with some 220 grit or lower to get good adhesion, and then clean it well!
That all being said, i still wouldnt trust any repair if the table is going to be flooded. Is it worth repairing and then having it fail, only to let god knows how may gallons all over the floor? Id just buy a new one, it will pay for itself in one run. Sawzaw the old one into smaller pieces and dispose of it, or you could patch it and keep it around as a runoff tray. Good luck.

Bondo has worked great for me

Just get some 5200 marine sealant,its what they use below waterline on boats and you can get it at any hardware store,http://www.lowes.com/pd_200558-98-06520_0__?productId=3020020

I have used "Amazing Goop Plumbers Edition" to fix a plastic kiddies pool that I use for the same purpose. I would imagine it would be fine for flood trays. It works well for use on dissimilar plastics. In any event, if you buy if from Plumbing Supply .com , if you do not like the stuff, they will send you your money back.

Gnome's tip on drilling the hole to stop a crack is golden.

Whatever you decide on I would think needs to as flexible as the drip pan itself. If you use a product that dried to a hard and very brittle finish it may crack on ya when you really don't want it to. Most local hardware's and home depots and Lowes carry a product called GOOP and their is a "plumbers style of it that is clear and dries flexible and stays where it is put for the sealing. I have used it on small water leaks in my aquarium tanks and filter boxes for years. You can also get aquarium sealant at the pet smarts and the like in the fish area that works super too.
