I am laying sheet vinyl flooring in an area that will have an access to a storm cellar in the middle of the room. I need to finish the edges of the vinyl on the floor and on the access door with as flush an edging as possible as this area will get foot traffic. Is there anything similar to the carpet edging which grabs the carpet then folds back? Any suggestions? Thanks!

I am laying 12x12 self stick tiles in a bathroom. I feel good about the project thanks to this great forum, but I am a bit confused about a couple things. Its recommended that I put down a 1/4 underlayment I have learned. Luan I think it was called. Is this the same thing as 1/4 plywood? I have ring shank underlayment nails to put down the floor, but someone was saying to staple it? Which is best? I also am assuming that I cut around toilet, and just butt the new subfloor up to it. And what is the best way to handle the door frames? Now once the luan is down, and I have patched and leveled the floor, I have a latex primer to put down. After that dries, I am ready to start laying out the floor right? Someone said I needed to put down an adhesive or glue, because glue on the self siick tiles wont hold over time. Well that sort of defeats the purpose of buying a self stick tile doesn't it? Is that really necessary? Thank you for your time in responding.
