Hello all - I am going to be putting vinyl squares over vinyl squares. I believe this will work. The existing floor is very solid mechanically, level and free of defects. I plan to off-set the new floor vs. the existing floor so that seams do not line up. The existing floor has a bit of a texture (not extreme). So I plan to sand first to ensure a texture free surface. I'll be using a hand held orbital (not belt) sander. Its a small kitch floor, so the larger orbital sander ( ~ 5 x 9") seems to be the best equipment to use. Does anyone has a suggestion on what grit of sandpaper I should use? Any other ideas / pitfalls to avoid would be welcome. Thanks.

I was originally going to tile my laundry room in the basement, but there is currently laminate in part of the basement as well that my wife doesn't really like so we are going to put LVP through a good portion of it. We also like the wood plank look as opposed to til so this should be nice. First of all, on the diagram I provided, there is currently carpet in the rec room and bedroom, linoleum in the utility and storage room, and laminate flooring everywhere else (the hallways and bathroom). The LVP will placed in the laundry room and everywhere the laminate currently is, and we will likely extend it into that storage room as well. It may even go into the bedroom down the line, but the rec room will likely stay carpet because it is exactly 12' feet wide so it will be easy to replace that. I wanted some advice on a couple of things. As far as the type of LVP, I noticed they have different thicknesses, some have a soft backing on them, etc. Any recommendations? I don't want super expensive stuff fro down here. Do we need an underlay? I see some say it is built in, and I can understand an underlay might be nice for cushioning or sound, but this is just a basement that does not get a lot of use so I don't care that much about that. Another question is how level does the floor have to be? This is on slab, and I imagine there might be some small cracks or discrepancies, but right now there is laminate on it that seems fine. If there are small fluctuations, is LVP forgiving? Again, this is just a basement. I figure I need to remove the linoleum so the floor level will be even throughout (plus part of the laundry room floor has a section of it already removed from when we had to break through the slab to fix a pipe a couple of years ago). Most of it peels up pretty easily with just a thin layer of adhesive left. Can that be left or does it have to come up too all the way to the bare concrete? Finally, which direction should this run, or is it a matter of preference? Right now, the laminate runs east to west which made sense at the time because the longest run was from the hall into the bathroom (the east wall of the hall is a door to outside). My wife still likes it this direction. Ideally though, I would like to start laying this in the laundry room because it is a priority to install a new hot water tank in there and I am waiting for the floor. I just want to get that done and may finish the rest of the basement in the near future. Also, any advice on keeping things as squared up as possible? This house is old so I doubt everything is squared up. Which walls should be followed to keep the planks even with? I appreciate you taking the time to read this and offering any advice. I have laid laminate before so I am familiar with the process of laying these.
