Concrete Patching Question

[rtate]

Thanks cbucner, that is a great help!!
When I look at the instructions for Hydraulic cement they say:
"only mix what you can use in about 3 minutes"
Should I be able to fill a 12' x12" square 1"deep in 3 minutes??

Also Shoud I use a bonding agent between old and new?

In the past I have used the bonding agent instead of water to mix the cement...

Depends on how fast you can mix the stuff and how well you trowel.

I'm a little pressed for time tonight, but will answer more fully tomorrow, if you need.

Thanks . any help/suggestions would be apreciated....

See what time I'm logging on? - This time of year = LONG work days

I can mix the stuff in ~ 1 minute (experience allows me to know the water to dry ratio and I use a 'margin' trowel to mix - real time savers) so have ~ the full 3 minutes to apply and trowel the stuff smooth. Folks mixing for the first time tend to take a couple+ minutes to get the mix to the correct consistency, which means it's got to be troweled smooth more quickly.

If you need a primer on troweling techniques, ask - but it will take me a few days to be able to provide that sort of detailed info - but someone else may help in the meantime.

(had you asked this question in Feb, when I was laid off - I'd have spent hours giving the details - maybe you should open your pool earlier LOL)

Thanks Ted I really appreciate the time you are taking to help me

I won't be starting this project for a week or so and I am sure that any info. or tips on techniques that you can give me would help tremendously !!
I will keep checking to see if you have had any spare time but please
post only when you have the time...
Thanks again
Robert.

So If my patch is 1 inch deep and about 12' x12" square,
how long does the patch need to cure before I paint over it?
Do I need to acid wash or etch before I paint??

Sorry for the delay

The patch should cure 24 hours, then be lightly acid washed to liberate any material that hasn't fully bonded to the pre-existing crete. Then allow ~ a day for the floor to dry before applying the paint

I'm out for the weekend on Friday (class reunion) but will be back next week
