I've been thinking about the feasibility of installing engineered bamboo flooring over my existing laminate floor. I've seen warnings online about this, so I'm checking in for more opinions. I'm aware of some potential problems, like trapping moisture underneath since the top layer will be waterproof while the laminate isn't. Plus, I'm concerned about the two layers moving differently over time, which could lead to gaps. However, my current laminate is a sturdy 12mm thick, and I thought adding another layer might actually enhance the floor's stability. While I'm not super worried about moisture (it's not prone to flooding and we keep things clean), I want to know if there are ways to prevent moisture issues. Also, how significant is the shifting problem really? If installed correctly, would it even matter? I'm open to suggestions and want to bounce some ideas around before making a decision.

In my experience, stacking two floating floors is just asking for trouble. You lose the structural integrity because both layers will shift on their own. The only slight upside might be a bit more insulation, but that really doesn't offset the many downsides. I'd advise you to ditch the laminate and not look back. Better to invest in making your current floor stronger, especially if it's your forever home!
Yeah, I'm considering options to boost support while I have it open. Any specific practices you recommend?
First and foremost, you should probably follow the manufacturer's specs for installation. They often provide key info on what works best. Generally, adding more layers can create a haven for mold if conditions are right, so it’s something to keep in mind. I checked the Optiwood specs, and while they don’t mention laminate specifically, they do caution against a lot of cushioning. Just make sure you weigh those risks against what you hope to achieve!
Honestly, layering a floating floor over another isn't the best move. The first layer would come up pretty easily, probably quicker than if you had screwed it down. Shifting can cause planks to separate, which is why overlapping floors usually don’t work out well in the long run. But hey, I haven’t seen this specific situation play out in practice, so I guess it's not a total no, just be cautious!
Good point about saving material! But trust the pros on this one. Have you thought about reinforcing your existing floor? That could be a solid move since it sounds like it’s in decent shape.
