In the areas where the original linoleum was installed (kitchen/entry), there is what appears to be a 1/4” birch underlayment that doesn’t exist on the rest of the floor. Should I tear it out or add underlayment to the remaining areas? Thanks.
Started tearing it out and it is coming up easy. I know I saw a video somewhere about the maximum deviation in subfloor for LVP, but can’t find it now. I’m using a 3 foot level. What would be the maximum I should go without sanding or filling? Also, I think I read or watched a video that stated low spots could be filled with tar paper on a LVP install?
I found only three spots of concern. One is around 3’x5’ with around 3/16” at the worst. The other two are around 2’x3’ with 3/16” depth. All are in heavy traffic areas. Several high spots need sanding and everything else is within 1/16” of level.
Also, I’m having no luck finding Ardex Feather or Henry 948 locally. I suppose most any brand of self drying, cement-based finish underlayment will work?
