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.

I would definately document and post pics, i am just gathering information, and parts from work. Any advice would be greatly appreciated. As for water resistant as opposed to waterproof, we use LM60 to seal concrete podium decks wich must be WATERPROOF to the highest level, and all our systems are under strict scrutiny from consultants and engineers. PM me if you want to discuss in more detail

I have a feeling my wifes gonna be a little worried when she sees this post LOL
 
:ROFL::ROFL::ROFL:

I plan to use this if my other test fails. It's a bit more expensive than I like but I might be able to get better prices that whats listed on the website.. shrug. I've read more on this product and it seems to be different during application. We'll have to see. I'd love to see how it works. Feel free to pick my brain though, if the application process is the same then you'll want to know some tips and tricks for sure.
 
The way we apply it at work it seems pretty simple. Our Gaaco rep and our consultants specd the LM60 for horiz. and vert. application. I can try to scan a detail off our plans for you if you would like to see it. On my current project we have used well ove 1000 gal. so needless to say i've been driving my waterproofers crazy with questions while doing my infield research LOL.
 
How thick does the application go on? Are you spraying or painting? Do you get adequate coverage with one application? If so, then the 42 square foot application of the 1 gal can would suffice for tank up to 250 gals.
 
I will dbl check mil thickness in the morning i believe its 18 mil. it takes two coats for waterproofing and one coat for damp proofing. The application process is pour and squegee pretty techicnical LOL. We also use neoprene at all hor. to vert. wood to wood joints wich i plan on doing also, mainly because i have access to everything for free. The only time we dont use neoprene is if it is cement to cement that was poured monolithic.
