Thanks. I used some dust masks and masked off the top and bottom of stairwell. multiple shop vacs were deployed..as you know it still goes everywhere! by Sunday 3 coats minwax fast dry gloss poly. Painted the risers. Trimming it out/more painting is the time killer.....Headache from forever is almost gone... Maybe putting some powdered tri-chomes inside the dust mask before I start the other half would help
