Hello, I was a student at LCTI for carpentryWhen our class got this package in, we had put this base molding along the bottom 90 degree joint where the floor and walls meet in the newly built closet that had been sheetrocked and spackled then painted. Before we started my class, I, and my teacher figured this would be a faulty product, because the present base molding was cut in 4 foot sections. Well wouldnt you know it the darn stuff dont stick where and when it's suppose to.
