Unconverting converted garage Floor refinish?

[gsracer]

Hey guys and gals

I have a question for you more experienced folks. I recently purchased a home with a illegal garage conversion, which im removing to get back the garage being as they simply drywalled in front of the garage door.

The house in block construction on a concrete slab. My question pertains to the floor. I already removed the tile with my jack hammer. But it left all of the mortar residue not to mention i gouged up the floor really good in some places. I know i can jack hammer it smooth but thats gonna take some time. I dont want to use floor leveler due to the fact that it is too much money.

Can i just clean it up really good and pour a say 1 inch slab of new concrete over the whole garage floor. Or would it just be easier to use a mixture of portland cement and sand to skim the whole garage floor?

Its a single car garage about 240 sq ft and the only use will be to park my 70 camaro on top. Thanks in advance

Jerry

you will neeed to rent a concrete grinder with diamond inserts (about $200 per day) and grind the floor , use water to kkep down dust or a good shop vac equipped with dust bag to contain the dust. After that, fill holes and even skim the floor with a mixture of portland cement, sand, acrylic fortifier and water. Follow directions on fortifier, your application is to thin for regular concrete so by adding the fortifier you are making "polymer concrete" . After you fill holes and skim the floor you may want to grind it again and then apply a floor coating

Ditto on the 1 inch pour over being too thin. I would check out the web site for Garon products, I think it is Garon.com or something like that. They make all types of products for concrete repair. I used stuff from them when I was doing facilities engineering for a 365,000 sq foot site. Great stuff, you may need to only patch the areas that got buggered up whe you took the tile off. The grinder sounds like a good idea for the initial smoothing, then you can patch from there and apply a floor finish of your choice
