Removed a kitchen wall in the middle of room, friend floated in the tongue and groove laminate and then glued down. 2 pieces are popping up, one on corner and other on side. Can I use tiny screws and wood putty? The floor is discontinued, trying to find a fix vs new floors. Thanks
Floating floors are normally fit around walls. Really, any flooring is. The right fix here is to work full flooring planks into the existing floor, which means disassembling some of the floor or using manufacturer-prescribed tools and techniques install planks in the middle of the floor.
In your case, without enough product, a hack fix is maybe your only option. I'd try to find some very thin plywood or synthetic sheet that you can use to bandage the filler planks to the original planks on the underside.
Otherwise, fastening the fillers down and hoping for the best is an option. If your floating floor moves around after you've eliminated the expansion joints, though, you may see opening of joints in the field.
