Based on some advice received on this forum (thank you AustinFloorGuy) I am going to use Ardex Feather Finish to help deal with some valleys I have on my second floor loft. I went to the Ardex website and saw a reference to WW Henry. It seems like they are both the same company but are the WW Henry products the same as Ardex? I can buy the WW Henry Feather Finish at Home Depot but want to make sure it is as good as Ardex which is not available very close to my house.

Thanks in advance.

Henry's bought ARDEX about 7 years ago. ARDEX feather finish has not changed, but the Henry's may just be ARDEX re-lables and packaged?? Never used it or tried it.
