The sidewalk section is removed, the bed of the section is coated with
rocks, and the section is framed for the new concrete sloped at a very
nice angle. I have the cement float and 2 types of edgers to put the
sections to the slab.
Can anyone elaborate on the process to use when installing a load of
3500 psi, with air, cement from a mixer truck? Thanks, in the past I
have always used the 80 lb bags from HD, but not this time. And, what
is a good sealer for the new cement, and when should it be applied?
How many square feet are you talking about? How many helpers do you
have? Have you done this before? What kind of access will the truck have
to the project?
Concrete is very heavy and it is time sensitive. The driver will expect
to be able to deliver and be out of there quickly. Except for a very small
project that takes a lot of people to do the work and the less experience
they have the more it takes.
Also consider that if you don't work the concrete correctly it is going
to be weak and you can expect the surface to scale in a year or two. Doing
it right is something of an art form developed with experience.
I hope all this has convinced you that you need someone on site who
really knows what they are doing when that truck arrives.
The truck will dump and you will have to spread and screed immediately.
Once he is gone, you won't be able to fill in any low spots. Actual
finishing can then take place. Also good to have a spot to dump any excess.
Sealer? Never. Billions of square feet of unsealed concrete abound in the
world for over a hundred years with no sealers on them.
have a good friend who cheaped out some years ago, he and his kids
layed the concrete.
it was HOT he didnt know to keep it moist and cover it.
the entire job turned back to gravel:( really, hazatd to walk on
lawsuit city if you ask me...
get a knowledgable friend to help at least the first time..........
I might suggest a sealer for those who are in cold snowy areas. Allow
the concrete to cure and in the fall use a water based sealer. This is
best done the first year. It is less important after than. It can help
keep the salt off the concrete. Frankly I believe a better solution is to
place it in the early spring and try to keep your car(s) off it if they have
any salt on them the first winter.

I was looking for a clarification of the art form.
