concrete floors - a thin pour?

I am looking for methods/instructions for pouring a 1 inch thick interior floor (on a wood sub-floor). Can this be accomplished with additives/fibers and control joints
no closer than 4 or 5 feet?

As far as I know, the only concrete you can do this with is gyp-crete, and it can't be used as a finished floor. I've heard 3 minimum. Now i'm not an expert at all, so please get some more imput. You might look for concrete tiles...

We are using a product called Cementi from Atlas Concorde tile. It is an 18x18 porcelain tile that is designed to give a very seamless concrete look. It is commercial grade and the tiles are designed to be installed extremely close to each other.

You might look into micro-topping products. Some products can get as thin as 1/8 topping.

Here is a link to the website of a DIY Network show about how to top a wood floor with a thin layer of concrete as the finish material.

Well.....today was the last chance to change the exterior door openings in the SIPs. So we had to decide what to do.
No concrete contractor really wanted to pour less than 2 inches, so we will be increasing the height of the rough openings and adding a little lumber under each door. The extra load also means that we get the choice of an added steel beam in the basement or a couple extra posts...

you can try epoxy additives as well. I experimented with silicone nitride and epoxy to make different pieces and i was able to get some rather flexible pieces done. I know of a company that does this in some restaurants for tables and countertops. Essentially they mix the epoxy with the cement mix and lay it ontop of the wood panel in an inch or so thickness. The elasticity of the epoxy compound allows it to flex without cracking. Of course this is on a countertop so im not sure how it will respond to a flooring situation.

I think there are lots of manufs making mixes that will achieve your goal. The limitation is in what sort of finish you expect from it. Most mixes will be heavily modified with admixtures that can prevent you from achieving aesthetics associated with standard mixes.

Some manufacturers to research are Ardex and Fox Industires off the top of my head. Really though, most metro areas should have concrete suppliers that can deliver a topping mix that is formulated to be placed as thin as that.

The 2 pour also has GREAT thermal performance. I have it in my home and am amazed every day.

You know how when someone accidentally leaves the front door open on a cold day? In a normal home you get chilly, and maybe even put on a coat for 5 minutes after you close the door, waiting for the furnace to do its job. Well, with a floor like this, the second you close the door, you feel comfortable again.

Good luck, getting a flat finish inside a house with the walls in place is really hard, because you can't screed worth a darn.

Thanks for boost of confidence!
We have a good bit of south-facing glass in the same space as the concrete, so we should get some good passive solar action. The heat saved in the floor should be nice.

you are looking for a product that is called americrete... it is a product that goes directly on wood and bonds to it wonderfully. you will probably want to put down a layer of diamond lath and staples with a gun. the people at Americrete are so nice and give a ton of advice about their product. one of the few companies with a true costomers service.t
