I installed a 10 by 20 cement slab (exterior but covered) alone and it dried a little faster than I wanted. Had to really trowel down which left some rough spots in the slab. The rough spots show the tops of the aggregate and I would like to smooth out the entire slab some. So I am thinking a self leveling cement? Or something like pool cool decking? Something I could put on then maybe spread it with a large squeegee like they apply asphalt sealer with? Any ideas? Does not have to be a fine finish, just uniform....not thick at all, just want it to stay on top of the slab which is now about 4 months old. There is a very slight slope just to get rid of water. I will then want to stain or paint the floor. Thanks.
