updated pics of stamped concrete curing

i have used some water/vingar on some spots to minimize lines caused by a garbage can rolling over the concrete. it has now been 2 months total. have had some rains on and off. the pics shown are a spot on the side of the house where the sun rises and when its midday this area is shaded, so it gets the least direct sunlight. some areas are still darker and blotchy looking whereas areas that get direct sunlght seem to be much lighter. i also included a pic of a strip between the stamps where the curing process is evident. i have heard though it would be a month tops. please offer your advice. i plan on putting an arcrylic sealer on this soon which i hope will even out any color issues.

Amanda,

I have to admit that this whole situation puzzles me a bit.

What kind of contractor did you hire if you have all these questions, and are going to be sealing this yourself?

In all honesty, their work looks fine to me, but they seem to have really failed when it comes to communicating & educating the customer on a custom stamp job.

I personally would NEVER let a HO seal a job like this the first time. As a matter of fact, I won't accept full payment for a deco. concrete job until I've sealed it & the HO can literally see what they are getting.

Here's my actual advice now:
- Wet all the concrete down together, as this will be a fairly close representation of what the sealed concrete will look like.
- If acceptable when wet, seal the concrete with a sealer SPECIFICALLY designed for decorative concrete, specifically powdered, colored release agents. You will not likely find this good quality sealer at a "big box" store, but at a concrete or masonry supplier.
- I would suggest adding "Shark Grip" or the eqivalent to the sealer as well, especially if you use this area in the winter.

Good Luck.

he is going to give me a hand with the sealer, i just want to cut cost down. do you think it would be ok to seal it even if the concrete has more lightening to do? when wet, it looks pretty nice.

If it looks good when wet, it "should" be fine sealed.

I wouldn't hold my breathe on the concrete lightening much more at this point. It very well could become slightly darker/bolder when sealed.

amandalc04 05-30-2010 02:20 PM

well i was going to use those 5 inch borders as a benchmark to see that there is still lightening to be done (last pic). if some spots look blotchy should i try to use a little more water/vinegar on that area?

also, i was looking at it like, the darker areas indicate that something went wrong since other areas not exposed to shade are much lighter from the sun

vinegar's acid,,, why vinegar again ? ? i'm w/jo - you hire us & you don't help,,, but if you DO help, its a signed disclaimer & an addl 5% :thumbup: that usually negates any ' free help '


amandalc04 05-31-2010 01:03 PM

by scrubbing a water/vinegar mixture on the concrete it opens the pores on the surface and can eliminate entrapped moisture.. ive read. it lightens the concrete when doing this also

tpolk 05-31-2010 01:10 PM

to me it looks like plain finished concrete. Usually stamping has patterns those just look like struck joints. Did he have iron forms that he layed on the concrete to sreate a pattern or just a small tool to make the lines? is he charging you for stamped concrete?

amandalc04 05-31-2010 01:18 PM

they were rubber mats that he stamped over it. it was a total of 900 sq ft for 4500 and he added the color too. because the pics were taken with my cell phone and because some areas are not lightened yet, its harder to see the pattern

I've never messed with vinegar & concrete before, and it seems like you could have inadvertently rmoved more of the powered release in certain areas than you should have. Like I said earlier, if it looks acceptable when wet, you should be content when it's sealed. Any sealer you use should be breathable, so it will not stop the concrete from completely drying out.

It's not the more typical patterned stamp, say like herringbone brick or random flag stone. It is a seamless stone texture stamp, becoming more popular in some areas. Here's a shot of one we did:

correct, its more subtle. is that concrete sealed yet? would i be able to apply the sealer even if the concrete has more lightening to do? is 4500 a good price for 900 s ft? i read that 8-12 per sq ft is typical

Yes

Yes, most every high end sealer is breathable.

I can't say for sure, pricing is a fairly subjective topic. Every area of the country varies substantially on pricing for a vast number of reasons. For this area, depending on the scope of work involved, that would be on the cheaper end. but then again, it sounds like you're doing more of the work as the HO than I'm accustomed to.
