Applying oil-based poly (lamb's-wool) 

I just got done putting my first coat and then saw this video. Mine wouldn’t spread so effortlessly as you seem to be doing. I think I didn’t mix enough mineral spirits with the poly? The poly didn’t seem that thick so I added about 20% spirits and it still didn’t slide well and I think I I put too thick a layer as the first coat . I’m wondering now how to proceed after it dries ? If anyone has any thoughts….

No bubbles how?

So i have to sand the MDF floor before applying?

How thick are you applying the polyurethane?

Hi What brand of Polyurethane are you using?
