Looking for information on underlayment for flooring that will go over concrete and wood subfloor. Even asking the folks at the store I get differing answers. Just trying to get a more narrow down "what is acceptable and what can I get".
On the instructions they suggest a 6mil vapor barrier on concrete, I would do that.
It says it doesn't need it on subfloor, but I always use it because it reduces the floating feeling of these click together floors. I also suggest you sand the seams so the subfloor is as flat and smooth as possible
I used the exact same LVP and underlayment OP had in other post. So far it looks and feels pretty good. Labor is expensive, doing what the manufacturer suggests for optimal results isn't something I want to do twice. I am happy and have a vapor barrier as well since I posted in OP's other thread.
I went with the 6mil vapor barrier for the concrete and lessor cost - same brand - underlayment.
I would of done the exact same thing. But, I convinced LL to give me contractor pricing. Seemed higher quality than the brands I looked at Home Depot and decided to go with that. I'll attach some photos of it finished. I think I paid $55/100sq or $45/100sq. I would have to double check.
I am excited to see the finished results whole-house when mine is done. Painting is being done now and I suspect flooring will commence next week or cabinets first then flooring. I expressed that kitchen cabinets go in first and then flooring for that room. It’s a waste to put cabinets on top of a finished flooring.
I was able to get the underlay for $30 per roll. All said and done after I started looking, LL was less at the contractor price same quality as what I had begun to see.
I look back and the time, some a lot and some not so much, I have spent picking out stuff is well worth it. I made sure I had back ups of things that if not available when I was ready to order, would be my go to in order to not stop the process.
