I m going to be leveling a concrete floor that is off anywhere from 2 to 8 depending on which are you measure from. I estimate that I will be needing about 85 bags of 90 lbs. concrete. It is too much for me to do it all in one go so I m thinking of blocking off the floor into three sections and doing it on three different days. I will have to wait for one area to set before going on to the next. Since the floor which I m going to level is already concrete I m not going to use any steel mesh but should I use any kind of concrete adhesive on it before I start pouring? I m not worried about the seams that I m going to have because the floor will be covered with Thin-Set and ceramic floor tile. My main question is: Is my reasoning sound and am I missing anything. I would appreciate any advice or suggestions anyone has to offer, thank you.

it will be far cheaper to get a ready mix truck to deliver the already
mixed concrete. they have a self leveling type to get it dead flat. 85
bags cost a fortune

I don't know about 'far cheaper' if all you count is the $'s----- *But
it will damn sure be cheaper in the long run, and a *whole* lot
easier.



are there any cracks in the existing concrete? if so the overlay will
crack and so will your new tile

Not to mention-- How did that floor get *that* far off? * *Is it
unsupported someplace and just waiting for another few tons to send
the whole works tumbling into a hole?



theres a mesh you imbead in the thinset but i dont know how effective
it is

I think I'd go with the fiber embedded concrete. . . . Strike that.
I'd call a couple redi-mix places, tell them what I was up to, and ask
for their recommendation.

its far cheaper to buy a large quanity of concrete delivered in a
ready mix truck than by the bag. i ran the number for a shed once, by
the bag was about 4 times the cost of delivered
