Getting ready to install hardwood...what is best under it?
Hello, we have ordered 3/4" solid prefinished white oak hardwood floor. Our subfloor is 3/4" OSB glued and screwed to 16" floor joists above our basement which is heated. During the lengthy construction period of our home the subfloor had raised at some joints from rain exposure till the roof got put on. We will be sanding the joints as best we can but what should we consider for underlay of the hardwood?
I have heard just a " paper" more or less to help with install to slide better. Also I have seen more like a cushy foam that I think seems good for imperfections as well as noise reduction maybe. Anyone else seen or used this type of underlay for hardwood?
FYI moisture in the home is low as we have been doing the interior finishing for 1 1/2 years.
