The rep swears up And down loose lay is fine BS. I've fixed so many over the years and refuse to do them. Full spread glue is the way More on reddit.com

We are trying to decide what type of flooring to put into an 11×16 guest bedroom in our basement. With the exception of occasional guests, the room would not be used much, other than having access to a 6’high book shelf. (No kids or dogs) We are considering loose lay sheet vinyl.

If you haven't committed, here's another opinion. I love and prefer loose lay vinyl even though it has disadvantages. Two big positive features are some integrated padding which is awesome, and eventual replacement is easy. When you tire of it or it does wear out or get severely damaged, you can pull it up, cut a new sheet using the old sheet as a template, and easily just put the new sheet down. For installation use a high quality double stick tape in stress areas where appliances like dishwashers and fridges need to move across it occasionally. Also put the tape across where you'll enter and exit the room. True, this tape does have to be pulled up when replacing, but it's NOTHING like removing and repairing after a massive glue job. Remember that you still need to prepare the floor to be smooth before installing, and there are true disadvantages- Lefty is absolutely justified in his concerns, but I would not say you can't ever move things or that you'll always have a hump. Humps depend on protecting the vinyl when moving things, and also how much freedom you can give the sheet to move a little. Before moving appliances, and I would first put down some heavy cardboard or other stiff protection to avoid distorting or wrinkling the vinyl, and keep your weight on that cardboard when you move appliances across it, and you definitely do need to leave other edges untaped so the flooring can expand and contract with temperature. It is best if you have or can install a little trim that is not all the way down to the subfloor so the end of the sheet is protected. Even with that care, it will never be so carefree as glued vinyl, but I still prefer it. You'll probably have to install it yourself because last I looked, most installers won't touch it because the chances of imperfections and little issues are relatively high and installers rightfully dislike call-backs. Spills - it should be waterproof but obviously not at the edges. Water spill? if small, ignore it and it will dry. Larger spills or sticky things or milk? Just pull up the edges and clean directly. I have it in the kitchen cooking area and the laundry room, and I'll replace it soon - after 20 years of use. Fringe benefit - it's soft and flexible, and scraps are great for keeping rolled up in the garage so you can slide around under your car when maintaining. This is a big help in the winter when the garage and concrete are cold. Good luck! More on reddit.com

Yah, all depends on the product and what the manufacturers specs are. More on reddit.com
