We have a concrete porch had become stained over 35 years.
Three months ago we applied hardware store "concrete cleaner"
then scrubbed with a brush and rinsed with a garden hose.
That procedure removed 3/4 of the stains, but now the
concrete is continually "shedding" grit under foot traffic.
Did we overdo cleaning and is it deteriorating?
What is the remedy?
Eh, like science says, "For every action there's an equal and opposite
reaction." Hard to escape science.
Overall, methinks you're OK since most poured concrete-pad projects
toend to be fairly thick -- way too thick to have your home
stain-cleaning project make a srious dent in the pad, no matter how much
"deterioration" you or your guests are feeling underfoot.
But really, if nobody mentioned in all of 35 years that your porch
looked crappy enough to affect propery values along the rest of the
street, why did you think it needed fixing up and making it feel all
gritty underfoot now? Especially since you were only able to get 3/4 of
the stains out as it is?
Come to think of it, nevermind. Some guys would just try to hide it all
under redneck grass (a.k.a Astroturf). Depending on where you live, this
may still be an acceptable option. Or not.

Of course you did.

And it may continue to do so. Check into concrete finishes. There are quite few
on the market, ranging from epoxy two part paints to proprietary finsihes
sutable for fork truck traffic. Do some research, check the budget and then
decide what works best for you. HTH
It sounds as if you must have used a cleaner with muriatic acid in it.
Normally, a good water rinse will stop that action. On the very remote
possibility that it is still active, make up a baking soda wash. This would
definitely stop the acid.
Look into concrete sealers. This is not a job for Thompson's waterseal.
There are several good commercial products available.
There is some good information at:
hope something here helps.
Keep the whole world singing. . . .
1. What are proportions for a baking soda wash?
2. Do you have a particular concrete sealer to recommend? The links
are extensive. Getting on in years with a large house to take care of
on a budget.
3. Is muriatic acid an environmental concern where there are water
Someone wondered why we tried to clean it up. It was slippery in spots
Concrete cleaner seemed like the thing to buy from our local hardware
store, and we used it according to directions, but had no idea it
would be so harsh.
