A contractor installed a cellar door for me recently and used white
concrete/cement to bed it in. This contrasts badly with the
surrounding normal (gray) concrete apron so I'd like to change the
color obviously without pulling it up or waiting 20 years for it to

Since you say cellar the old is dirty and moldy, you could clean the
old easily, laundry bleach will kill mold in minutes, I use a garden
sprayer. You could then powerwash the old and use Muiatic acid if you
want it real new but bleach often works. If it still doesnt match rub
dirt in the new. What he put in is grey with grey portland, White
Portland and White sand and gravel would be expensive and made on site
Just because I use the word "cellar" it does NOT mean dirty and moldy!
The cellar door opens into the front concrete courtyard made from some
100 year old cement product which appears to be gray or at least
regular concrete color. It's quite clean and has no mold.
You must be joking!
I don't think so. Have a look at:
The second variety is white. I'm sure there are other white ready
mixes too. Lowes sell a white masonry cement by TXI.
Dyeing it looks more viable. There's a sakrete charcoal cement color.
This is an example of how you have to watch contractors like a hawk.
If it can be screwed up, they'll do it.
A neighbor in our condo stained some furniture on the outdoor concrete
deck in our condo atrium. When the condo board started to rumble about
it, I got out my craft paints and painted out the dark brown stains.
This was about 6 years ago and it is still good. You can get small
bottles of acryllic craft paint at Michaels or Joann. Mix a black,
white, a little dark brown, a touch of blue and yellow. I used two or
three shades, as in "faux finishing" to give the painted area more of
the texture of concrete. Use a round stencil brush that is flat on the
end, squeeze out excess and dab on thin coats. Nothing to it, and a
heck of a lot easier than messing with mortar.
