Matt, I have a front porch 36x12 area which I took down
to bare wood by hand 30 years ago and have since put 3 coats of polyurethane
over the years sanding between each coat the last coat applied with the whizz foam roller. It is in excellent shape with no peeling just needs freshening.
Karl is right about prep, but after all the cleaning and scrubbing do you think i can get away without sanding by using " liguid sander" as a last step?
My back won't take sanding anymore.
Thanks.
