In this video I'm pouring a new concrete floor over an existing concrete floor.
If you want to know if there's anything special you have to do before pouring concrete over concrete, I show you and explain it all in the video.
My rule of thumb is: If your pouring at least 3" thick or more over your existing concrete floor, patio, slab, driveway, you don't have to bond the concrete together.
If your concrete pour is less than 3" thick, then I recommend using a bonding agent like Weld Crete to bond the two concrete slabs together.
If you're using Weld Crete, just brush it on your clean concrete, scrub it in and make sure it covers everything, wait for it to dry to touch, then pour your new concrete right over it.
If you're slab is thicker than 3", then you just pour the concrete like you would any normal slab, floor, or patio.
This is how I've been doing it for over 39 years with no problems.
