I am planning to lay down 3/4" solid unfinished 7" american cherry. I've installed some (10+) hardwood floors but have no experience with wide plank flooring. subfloor is plywood. michigan. climate controlled furnace/ac. no radiant flooring or anything unusual(traditional joists over a full basement).
I think I've done my research, but I can not come to consensus on staple down with glue assist or just staple or cleat. the room is only 350sf. with wide plank, should I be laying down a bed of stauf TDS or just a snake of PL400(or similar) on the back of each plank? I am leaning towards staple and a snake of adhesive as it is easier(and cheaper) than troweling down stauf. If i use just a snake of PL400 on each plank, should I use a vapor barrier or just red rosin paper?

With glue assist you need to glue to the sub-floor. Use red rosin to cover the floor after it has been laid, if other trades need to work over it.

Avoid PL for flooring, and use a Bona product of something specifically for flooring - PL doesn't move at all after its cured, and you want to retain some flex to allow the floor to expand and contract seasonally.

I know the trowel is a pain, but its the better method. Its only 350sqft, that's a pail and a half maybe depending on the yield and trowel size. With the full spread you're less likely to see individual planks fail or pop.
