We are remaking our garage into a bedroom , and we have a problem with the floor being level. the Cement has a 1" difference from front to back. I know their are levering products but so far no one has been able to give me a name of a product. my home stores have been of no help.

If you only have one inch fall, I don't see any problem. Three or four inches are typically found. Recheck and confirm if this is correct.
If you do, indeed, have such a low pitch (1"), it would not be noticeable in a finished room, especially if you have carpeted flooring & a base trim around the perimeter walls.
If the pitch is greater, you need two products: a self-leveling compound and a pre-treatment solution that would etch (create a bondable, rough surface) the existing concrete. This is best done by a professional, since precise conditions of humidity, temperature and workmanship are required for a proper finish. Also, look at the wood sole plate at the garage door corners. Replace any wood rot with pressure-treated wood. If the horizontal 2x4 plate rests on a raised concrete curb, you have a nice situation for top-coating. If the wood rests directly on the sloped floor, make sure you have pressure-treated wood in direct contact with the slab. Any other wood type will eventually rot from moisture infiltration. If you need to raise the surface at the low end perhaps 2 or more inches, you will need to add a horizontal pressure-treated infill between studs so that you can attach wallboard to the bottom edge of the walls.

PLEASE CONSIDER THIS: If there is a slope in ANY room which will be used by a person with limited mobility you are only asking for problems.

People with poor balance, those who use a cane or walker, or even a person in a wheelchair have a greatly increased chance of getting injured.

One does not have to be old to have limited mobility. I was only 33 years old when I could no longer walk and have since been wheelchair-reliant.

Limited mobility can happen to anyone at any age. Please let's all build and remodel with this in mind.

Thank you for taking the time to read this.

Katie,
The best product I know to level your floor is Ardex K-15. It is a self leveling portland cement based product. It comes in a 40-50lb bag.
Mix it up exactly as directed{amount of water listed on bag]. You should precoat the floor with a latex admixture{"milk"}. Let that dry according to manufacturer instructions. Pour Ardex mixture at low end. It will flow and level itself. Be sure you have blocked off at walls so mix doesn't run under the walls. It has a very high psi rating of about 4000lbs. As a former floor mechanic I have personally used this product with great success. I have also recommended to other do it yourselfers and they also have had great success. If you need more than 1-1/2" thickness you must add some aggregate. You can purchase this material at better building supplies or floor covering installation supply houses. Good Luck

Hi Katie,
Sometimes it is better to install a subfloor base rather than just using the garage floor. You will probably have to much moisture build up and tempature change with the slab. If you have the head room to install a subfloor spanning the room with floor joists is usually better than the garage slab. You can eleminate most ot the moisture by using a sheet of 4mil plastic over the garage slab and install your floor joist over it and level the floor joists. This makes a better subfloor base than the garage slab. there was a show on HGTV called Fix-it-Up that showed the process of doing this type of room.

Katie:
We recently did very similar to what you are proposing. We turned our garage into an extra room to serve as an exercise/game/spare bedroom/etc. The floor slope was about an inch across going from our wash room door to the garage door opening, but this was so slight that after adding carpet the slope wasn’t noticeable. First we raised our garage door fully open and used this to locate where we wanted our interior wall. Second we trimmed the excess garage door rail (track) off and relocated the rear hanger brackets. There was about a foot of extra track that wasn’t needed. By doing this it left the front of our home looking the same as it always has, but it also gave us approx. a 10-foot storage area in the front of the garage, and if in the future we decide we want the garage back we can remove the wall and use our garage again. After, installing insulation, texturing and painting the walls and ceiling, adding lighting and ceiling fan the room was complete and it has served its purpose well. Good luck with your project!
