What exactly is this 2 in 1 cushion thing I see people talking about on this board. I am installing br111 7/16 solid onto concrete and am concerned about the floor being to hard.
Maybe this thing is for me. What is it and where can I get it?

two in one is a moisture barrier affixed to a foam pad. its for a floating floor install and you can get the stuff at almost anywhere they sell lamitate floors. As for the floor being hard I would say most wood floors are just that, and floating it over a pad is the least desirable way to install a wood floor imo. Sometimes it's the only way but if there is a choice nailing or gluing to the subfloor is the route I find people are most satisfied with.

It cannot be used with your product. You have a nail or glue only product.

I sure hope you know exactly what your doing and what you got yourself into with a solid wood going over concrete.

Don't hang yourself. There is no margin for error what so ever.

You can glue the 5/16 and 7/16 and BR-111 will warrantee it (they will not pay you for your labor). You must check your concrete’s moisture levels with a calcium chloride test (you can get it at the floor store), it must be within acceptable range. And you must use an approved urethane adhesive. That being said I personally would install a plywood subfloor and blind nail the wood (search this board for instructions use terms like plywood and concrete). It is cheaper than glue and a lot less risky than gluing a solid to concrete, even the thin solids. Whatever you do, do a lot of reading before you take any more steps. You need to understand the product you have and the install options that are available to you, if not you have a recipe for disaster having solid wood going over concrete.

Thanks for the responses. I am pretty well read up on solids over concrete and am aware of the risks.

But please elaborate regarding your suggestion!!!

Are you suggesting attaching the plywood to the concrete using fasters NOT glue. Then nailing the floor?

OK BUT- I still need a barrier for moisture ontop of the concrete. What type works with concrete fasteners?

What are concrete fasteners?

I have talked to over 10 contractors each with different suggestions.

What good is a moisture barrier when you turn it into a moisture retarder, by poking holes all in it with fasteners??

It is really not my fault so many contractors choose to do things differently.

In essense slapping more wood on the concrete in the form of ply simply turns a solid into an engineered anyway. Why you all are so afraid of new products?

If the floor fails- it is the contractors fault 99% of the time.

BTW I don't know what fasteners are that is why I asked.



annnnnd I can answer back "What is the use is a licensed contracter?". They never do the work anyway as they hire Jose to do it and Jose does shoddy work, speaks no English and the price is huge for the quality of work you get!

Snowcone, Here is a link to some info on installing plywood on a slab. There are other ways to install it but this is simple and has always worked well for us and we are in a very humid area.

Jose and his friends are the only people we can find that will show up for work everyday and do this kind of work. Some of these people do excellent work.

Well, I am a licensed contractor and I do all the work myself. I do not hire or sub out the labor as I have found very few who will do it to my high standards. But my clients pay for my experience, expertise and high level of quality. And I am usually not that much more than the guy who subs the labor out to Jose.
