Rip out all your wood, remove any trim you don't want to piant, mask off any area's that need it. key the area up REALLY well with some scotchbrite ( and lots of it) , hoover it out, I wiped mine clean with some cell thinners I had, then when all super clean and dry, mask - stipple the Protectacote on ( but don't mess about with it too much), leave for an hour of two, then apply the second coat - leave at least over night, longer wouldbe better.
JOB DONE.
Thats how I did mine and I very happy with the result.
If I get round to it, I'll post a pic
