Running out of ideas - Laminate Install.

my experience level. install 1 11x10 room and attached hallway with laminate, all went easy.

going in to the next attached bed room, I have reached my limit and need some assistance.

it appears the flooring is uneven, I finally broke down and tried some self-leveling command, I think I mixed it a little to thick, but it appeared to help, but I only did the what thought was the affected area.

When I lay the laminate down lengthwise about the 3 row the laminate begins to bow in to a shallow u shape, adding another row makes it a more more pronounced shallow u with the leading edge higher off the floor than the previous row had been.

I am only using 6mil(?) vapor barrier, but was wondering if I use cork or a vapor barrier with felt would be better and help level out the floor. I like the idea of using cork for the silence it supposed to bring to the laminate.

Or do I have retry and level the entire room?

The laminate is St. James which is Lumber Liquidators house brand. There is nothing in the warranty about using another type of underlayment.

Thanks for the help.
Happy New Year.

 

Welcome to the forums! It would really help if we could see what you see. Can you post a couple of pix of your situation? We can give better advice with the pix. http://www.doityourself.com/forum/el...your-post.html

 

I can seem to get a shot of the bow from the first row to this row which is only 4 boards wide.
I checked with my leveler, but it is only 3 ft. the 3 bubbles seemed to be near the center.

thanks.

 

When you poured the SLC, did it flow to the low spots? If you mixed it to trowel in, yes, you made it too thick. Your floor has to be level, and the only thing I can suggest, if you haven't gone too far, remove all the flooring and padding, and start over with SLC or some other leveling method.
