OSB Prep for Laminate Flooring
Hi all, first off, just want to so thanks for taking the time to help a novice here!

About to install floating laminate in kitchen & living room.
- Entire house subfloor is OSB.
- Kitchen = particle board layer over OSB (to preserve vinyl levelness with carpet in living room).
- Living room = OSB.

1) Should I remove the particle board in the kitchen instead of installing more particle board over the OSB subfloor in the living room? Just trying to get both the same height.

2) If I take out the particle board in the kitchen leaving just the OSB subfloor, what is the best method for this? Just crow bar the particle board out?

3) If I float the laminate flooring over the OSB, should I prep the OSB like add a moisture barrier or moisture resistant paint? Laminate flooring has attached sound barrier foam.

4) Can I sand OSD in order to level out the high spots (if there are any)?

Thanks so much for helping me out! Hopefully after all these home improvement projects I'll have some wisdom to pass along.

JetSwet, thanks for the response!

Particle board only in the kitchen. Living room is carpet over OSB subfloor.

Removing particle board in the kitchen doesn't look too hard.

Haven't leveled the surface yet because it's still covered with carpet in the living room and I'm just now removing the vinyl in the kitchen. Visually speaking it looks good but I'll take a level to it after I rip all up.

So when finished it'll be OSB subfloor, then vapor barrier, then floating laminate (with sound barrier attached).

I'll grab the vapor barrier at Lowe's tomorrow. Thanks a lot!!

If you end up leveling the ply with morter or leveling compound make shore it's totally smooth.
Make shore you leave 1/4 space on both sides of wall for laminate to expand and contract there is a box that you will need with spacers and the block if they don't snap in easy use the block gently tap the planks in make shore the seams are staggered at 12" apart.
