Floor installation question - What is the good stuff for leveling the subfloor?

[gordorad]

Need to finish up some flooring.  This sub floor is uneven, almost an inch drop in 5 feet. 

I've read about some self leveling "stuff" you pour on the floor.  Does it work?  It is easy to use? Any tips on using it?

The floor i'm installing is the prefinished laminate from Costco.  Perhaps Harmonics??  Can't remember the name.

What is the name?  I've a Lowes very close and also Ace hardware if that helps.

thanks.

   Are you satisified that the floor isn't going to drop more? Any possibility of raising the low portion? Lowes has a pourable floor leveling compound that comes in a powder form. I can't remember how deep you can pour at any given time but it works well. Any leveling compound you use will be a problem if the subfloor is still moving.

What is your subfloor material? That seems like an awful big drop for such a short run.

it is plywood.  Yes, it is a big drop.  Shitty carpenters I guess.  The house is about 40 years old so I am pretty confident it is not moving.  I think it has always been like that. 

No possibility of raising the low portion.  It is the 2nd floor hallway. 

Maybe it is 3/4 of an inch, but trust me, it is not level.  Not even close.  You can see it with you eyes.  Didn't notice it until the carpet was removed.

Id cut shims (3/4"- nothing) and bring it up to level. Never had luck with floor leveler. It usually cracks and then you will hear it as you walk on it.

Levelquick RS from Custom Building Products is the S$$$.  You will need to prime the floor and seal any areas that the material could flow into.  After the prep work mix it per directions, pour it and walk away!  Home Depot sells this product.

Thanks...Level quick is it!!  That's what I was looking for.  Can't use shims with this type of flooring....
