Ladder pour.

today's pour. Start of the ladder. 
poured this section on Thursday the 9th. Was the 5th section to pour and the best so far. Getting the pebbles to show up top is real hard. First you lay down concrete to about an inch and half from the top of the forms.
then you put the last inch and half in all at once so its the same Consistency, IE: all dry about the same time.
you then sprinkle the pebbles onto it.
then press them down with a 2x6. Covering all the pebbles.
then go skinny dipping for about an hour while it dries some (this depends on the Temperature, sunlight, wind, yesterday was about an hour)
then you roll it with my home made 150lb roller! Being careful to not dent the concrete, your just rolling the rocks flat.
you then start brushing the concrete off the top of the pebbles, exposing them.

This is much harder than it sounds, and takes the longest. The concert has to be dry but not dry. Its more of a feel than anything.

after it has dried a lot more, you brush, then spray it with just little bit of water, the water takes or is suppose to take just the top layer of concrete off. You have to get this just right. To much water pressure and you will take pebbles out, leaving little Indentions and uneven spots.
to dry and you wont take any off and the pebbles wont be exposed.

If you cant get it (the top layer of concrete) off, then when it dries you use muratic acid mixed with water to eat (called etching) the concrete off.
Again, to much acid and you will take too much concrete off and the pebbles will come loose.
