We recently finished an exposed aggregate walkway and front entrance. The end result turned out beautifully! First we poured with a 3/8 rock size for a pebble finish when the job is done. We bull floated the slab and edged the sides making sure there was no ridges. Then we applied horizontal retarder, this causes the surface of the concrete not to harden. We waited the appropriate amount of time and then pressure washed the top off, "exposing" the rocks underneath. Washing to early causes blow outs, but wash it to late and the surface will not come off. It's all about timing. The next day we acid washed it to get rid any white splochy spots. Lastly we put in the control cuts and applied sealer to give it a shiny gloss look. The sealer really brings out the colour in the rocks! And there you have it. Another job done!
