I just had new sheet vinyl flooring put in my bathroom. I need new baseboards. I bought vinyl baseboard by the foot--it cuts white a blade. The problem is how do you do the corners?? With wood you miter the corners; but this can't bedone with the vinyl baseboard. How do you get it to look professional?? I need to get this done this week.

installed a few miles of this stuff.
first piece is butted into the corner and glued. the next piece, with your utility knife round and under cut the toe so it fits over the first and gives a mitered look.
a bit of practice and you'll have it
if the corner is out of plumb,trim the ends to match

how do you cut an outside corner?
