I am installing an oak floor and after ripping up the previous carpet found that a section (2'x 10') is unlevel from a joist to where threshold will be.
A friend suggested using a leveling compound, then 1/4 underlayment.
Where do I find this Self-leveling compund for wood sub-floor? Do I need a primer? Is it a mix? Will is take being nailed?
The new flooring is 3/4" oak (tongue-groove 4" wide plank). I am using an air-nailer (hammer-flooring type) and wondered if the nails will hold? the amount of leveling is only an 1/8" to a 1/4" at most.
