dear sir: i am going to lay linoleum squares in my bathroom. i know nothing about this.the old floor is old plywood, not too bad of shape.I bought a primer to put on the old plywood, one recomended. I have armstrong tiles, peel of backs.how do i get my starting point,m and how do i cut all those angles around the tuband flush. also can i put the regular glue down used for commerical tils just make sure that they do stick down, I don't know if i trust the peel offs. Thankyou Terry.
