Stamped Concrete Concerns


Hello,

We had our patio poured yesterday morning (finished about 10AM). It rained pretty hard about 12 hours later and "antiquing" dust was all in the air. They returned this morning and appear to have sealed it (about 24 hours after the initial pour).

They are using Butterfield products. We are not too picky with the colors, but it appears to me that something is off with the secondary color since it's very dark and not just in the crevices.

Does this job look OK, or does it look like they did something wrong.

Thanks!
Steve

Re: Stamped Concrete Concerns


Did you use a pigment in the base concrete for a more permanent base to work off of for a more permanent color? I so see some apparent color or texture in the second photo.

Many pigments do not really stain the concrete in a true way. I used several (3 or) semi truck loads of pigments per year and had to maintain uniformity because we had to match our inventory. We never used natural pigments and only synthetic metallic oxides. We never could afford to use anything with carbon black in it because it is not permanent and can wash or wear off.

For a variable small, varigated color on a patio, you have more latitude and don't expect absolute uniformity since the base concrete has a variable toning applied to it.

Yes, it was my understanding and appears the Concrete was stained throughout in the base color. I wasn't sure if the heavy rain (for about 20 minutes) last night would have caused any issues. It was about 85 degrees most of the afternoon so I would imagine it cured pretty quickly before the rain.

It was definitely a powder on the surface. I touched it yesterday and it was chalky on my finger and during the rain last night it created a lot of dust in the air, so I'm not sure if they would have added more, etc..

Thanks

Re: Stamped Concrete Concerns


The reason it's darker than you anticipated is because they left alot of the release (the chalky dust you saw flying around in the rain) on it rather than scrubbing/power washing more of it off. It's kind of subjective on how much release to leave on, though.

Two things I wold take larger issue with is what kind of sealer did they use that can be applied 24 hours after pouring and why on Earth couldn't they have shifted the saw joints over a little to fall into the pattern better? The way they sawed it is lazy IMPO.
