Roof Coating for sealing a plywood tank??

  • We are currently upgrading MFK. thanks! -neo
Actually my plan is to have my brother order it in. he works at a construction and lumber supply store.. been there for years. They can order in the product and I won't have to pay the shipping. He also get a discount so I can feasibly get the Primer with the Max Stretch for around 75 to 80 bucks, enough to do a fairly large tank
 
GacoFlex LM-60

GacoFlex LM-60 is a 100% solids liquid applied two component coating that cures into a water resistant polyurethane elastomeric membrane.
LM-60H is designed for application on horizontal and low slope surfaces, at the rate of at least four gallons per 100 square feet (15.14 L / 9.3 m²), to yield a 1/16" (.16 cm) thick membrane. LM-60V is designed for the same application rate and yield on vertical surfaces.
USAGE

Intended primarily for use as a high build waterproofing membrane over concrete, metal and plywood. GacoFlex LM-60 has ANSI NSF Standard 61 approval to line potable water storage tanks 10,000 gallons and over. When GacoFlex E-5320 is used as a primer, LM-60 has ANSI NSF Standard 61 approval to line potable water storage tanks 30,000 gallons and over. For non-potable water facilities where pH is less than 6.5 an acid resistant version of LM-60 is available for use.
CONSISTENCY

LM-60H & LM-60V are thixotropic. LM-60H ranges between 25,000 to 40,000 centipoises at 75ºF (24ºC). LM-60V ranges between 100,000 to 160,000 centipoises at 75ºF (24ºC).
COLOR

Black.


Sounds like it would be a very comparable product to Ames. Maybe you will be the ginnea pig. Wanna volunteer to document and post pics. I can help with advice when it comes to racks and scratching the membrane.. i have that experience. the only part that concerns me it the "water resistant" I'm sure it's because they can't claim to be waterproof without locking down teh parameters of it's use to nil or nothing.
 
Good info.. didnt mean to start a controversal thread but good stuff here. oh and im not really trying to cut corners. If you've seen my other threads and posts, i've already used the right epoxy that is fish safe. I'm only looking to find other products to cut down on prices. Im creating a fish room with several plywood tanks and ponds. That gets a lil expensive using epoxy. keep the info coming! im curious to know what other people have used.
 
Theres isn't any hard feelings,we all wouldn't be men if we didn't have our own opinions on building things.Controversy always makes for a good conversation-we just need beer now.:headbang2Like I said,who knows?I could be wrong or right.........It's always a good thing to discover new products at cheaper costs that are reliable.I openly admit,I didn't see that this product had no form of tar in it but I do know that 99% of roofing products do have tar,which is partly oil and chemicals as previously stated.If it is totally non toxic and safe to use then I would support its use.BUT-I still say who knows how long it will last?I know that he said he used it for 4 years without issue and thats great but will it last another 4 years or ten years etc?I just know that when I build my gargantuan tank that I will want something that gives me no problems for my life time.

Couldn't say the first part better. I agree. As for it lasting a lifetime, I seriously doubt it. I'd expect to recoat fairly often. The tank I build was recoated 2 years ago from what I was old. They drained, dried, and painted a few new coats on with my old can. Atleast thats what they said they were going to do. The people who have mt tank were the ones I used to rent an old apartment to that I formerly lived in.. thus the tank..
 
see that could be the part that sucks.If you have to recoat every 2-3-4- years then what will I do with the monsters in it for 2-3 weeks while I empty it coat it dry it etc and get it up and running again/cycling etc.Lets just say I build a 500 gallon,definitely not small and definitely not "big" but,I now have say 5 fish over 24" in it.......thats a big problem.we cant just go rent 5 125 gallon tanks to hold them in.Totes are too small etc.catch my drift?Thats where the problem lies for me personally.I want something that is damn near indestructable.If it costs more now-but I wont need to keep resealing and coating it thru the years-thats for me!I'm a big fan of doing it right the first time so it will last a life time.bottoms up man-lets drink to that!

Again we agree. I was just letting people know it can be done. It's no longer cost effective in most cases. In the long run it's not cost effective at all. And no, I would not use it for LARGE projects. It simply "can" be done.
