Lighten Stamped Concrete Antique With Muriatic Acid

[@freeindeed5393]

This is the video I needed to see after watching about 100 of them! Thank you!!

[@stealthfirefishing]

I don’t really work too much with Concreat but I have had times where I needed to try. These videos help me learn the differences between different forms of harder, antique, and coatings. Thanks for taking the time to show us.

[@DecoCreteTV]

You are welcome!!! Thanks for watching, we appreciate the support👍

[@JJHardwood]

Thank you from someone just learning the ins and outs.

Will this get rid of etching on an older stamped concrete patio.

[@DecoCreteTV]

Thanks for the comment! I'm curious what you mean by "etching" on the old slab. This technique is normally used to remove powder release from freshly poured stamped concrete prior to sealing. Could you describe what the concrete looks like right now and what you are trying to achieve? Thanks for watching!!

[@teasmaniota]

I had some new concrete work done and concretor walked on older redbrick coloured concrete path with fresh concrete on his boots. How do I get rid of his bootprints? Other concretors have suggested acid wash but will this affect the red colour?

[@DecoCreteTV]

Thanks for the comment! This kind of situation can be challenging. The first thing to do is scrape as much of the concrete off as you can with a putty knife or a margin trowel. You should be able to remove most of the concrete, but the stains will probably still be there. Muriatic acid will attack the stains, but it could also discolor the walkway in the process. The best thing is to start with a very light mixture of acid, 1 part muriatic to 10 parts water is a safe starting point. Soake the walkway down with water first, then try the acid on a small spot to make it does not affect the red color. You'll probably have to adjust the mix ratio one way or the other after that, and the key is to find the dilution that'll remove the stains but won't hurt the walkway. You may not be able to completely get rid of the stains, but with some scrubbing, you should be able to soften them up to the point that they aren't as noticeable. Make sure to keep the rest of the walkway soaked down and rinsed off to lessen the chance of the acid & water mixture damaging the rest of the walk. After you're done, thoroughly rinse everything with water so none of the acid is left behind. Thanks for watching!!!

Thanks for your quick & informative reply. @@DecoCreteTV

[@selmo6283]

Could you tell me if I can do this after the sealer has been applied?

[@DecoCreteTV]

Thanks for the comment! Unfortunately, this only works before the sealer is applied. You would need to remove the sealer if you want to lighten it up at this point. Sandblasting would be the best way of removing it, I'll leave a link to one our other videos on sandblasting. Thanks for watching Deco-Crete TV!! kzbin.info/www/bejne/d4SsoqSVq96Id6s

My garage concrete floor has a wood stain dried off for probably 10+ years from the previous home owner. Would acid wash remove it? Thanks!

[@powerhouseconcrete6399]

Hi I do appreciate the helpful tips. Also, I commend you in the awesome work you guys do. I had a question. Is there a reason why the liquid release is not coming off easily?

[@DecoCreteTV]

Thanks for the comment!!! Liquid release is normally clear, and you would only be washing it as a precaution to make sure that no residue is left behind. Is this the case, and maybe there is something else on the slab that's coming off? Or did you add some kind of color to the release? The technique in this video is meant for removing powder release. If you can tell us a little bit more about this specific situation, it would help us give you the best answer possible. Thanks for watching our channel!!!

[@powerhouseconcrete6399]

Thank you for the promp response. Yes it is liquid release and no, there was no color added to the release. there is some tint to the base color due to the liquid release residue, which is fine. But in my case there is a section that is a lot darker than the rest of the area.

I would like to send you a picture, but I do not have an option on here

@@powerhouseconcrete6399 A photo would definitely help. You can send it to [e-mail]. I will take a look and get back to you with a suggestion.

You amaze me with your techniques, Jason. I've been to your company for a few seminars and have a question. I have a small decorative patio that's a light gray (with dark accents) that's due for a reseal and I am wondering if I can restain it as a medium brown and don't mind if there's still some of that dark gray left in it. Have you had success with changing colors on two year old concrete?

[@DecoCreteTV]

Yes. Revival is solid color coating that will work perfectly for this. However, all the sealer must be removed first. www.deco-cretesupply.com/products/sealers-coatings-stains/deco-crete-revival

[@evanyale2596]

How long can I wait to use this technique? I have a week old pour that should be light gray with dark gray release, but it looks purple. Wanting to wait to see concrete fully cure to tell if it's the concrete color or too much release. I've already soap broomed it and power washed.

[@DecoCreteTV]

Waiting until the the concrete is cured is even better! You can try a buffer as well to get rid of excess release: kzbin.info/www/bejne/jpPYc5WQqa2FhNE

[@evanyale2596]

@@DecoCreteTV , awesome! Thank you very much!

[@evanyale2596]

So the buffer worked great on the purple colored release and too good in some areas where I took most all the color and maybe even the nice finished concrete to expose some less fine rock. Is there a nice color enhancing finish you would recommend to help me get some contrast ?

[@GrumpyAndCricket]

Thank you! We can learn everyday!

[@DecoCreteTV]

You're welcome! Thanks Dave!!

[@david_gloria4_pb]

When can ypu wash off the color hardening on stap cement?

[@soccerdoctor911]

Would this technique work if you stripped off the sealer first

[@DecoCreteTV]

yes it will! thanks for watching sir

[@TimberTea]

Can I do this if my acid wash has been sealed?

[@DecoCreteTV]

no not if already sealed

[@wandamiller5344]

I stained part of my garage floor and now I've decided to lay ceramic tile. What can I use to remove the stain I used initially?

[@DecoCreteTV]

Floor grinder would be the best solution for removing stain. Maybe check with the tile manufacturer to see if it even needs removed.

[@jaggernat]

Can I remove deep scratches on my bluestone with muriatic acid ?

[@angelc7984]

I have the same issue, Will this work with colored concrete? I had a colored concrete poured (Cherokee red) and used a charcoal colored powder for the release but it’s to dark. What can I do? Will the acid fade the red concrete color or just the release?

[@DecoCreteTV]

This technique will work fine! The acid will not fade the red. Thanks for watching!

[@kolankprof]

Thanks, Jason!

[@DecoCreteTV]

Thanks for watching Thomas!

[@edwinmartinez5335]

We did a stamped concrete patio over the weekend and one of my guys messed up while stamping and floated the release and restamped. Can I use this technique to remove the floated release or What’s a recommendation to get its based color which is solomon Rosemary

[@DecoCreteTV]

Thats a tough one Edwin. You can use a stronger mix of muratic acid but there is a slim chance it will get back to the original.

[@arobyte]

Honestly learning a lot from your tip series! Thanks. Using these to train my workers!

[@DecoCreteTV]

That's awesome! Thanks for watching!

[@flat4wankel]

Can i use this to remove stained color on border? Some guy did an awful job and color does not match and im not happy.

[@DecoCreteTV]

Lots of variables in the situation described, you can call one of our locations to get a recommendation from our experts! Columbus Location: [phone]

[@41585elviejo]

Will this method remove contaminated grey concrete, we poured two strips in a driveway and the grey got contaminated and i need to remove the release?

[@DecoCreteTV]

It will, although we would recommend starting with a degreaser as muriatic acid can discolor the grey concrete

[@ricktrejo4798]

Hi I stain a slab with black stain and then I sealed it but part of the slab it was to dark would this work work for that please help

[@DecoCreteTV]

not after it is sealed, sorry

[@bwash6249]

Great video, thanks

[@DecoCreteTV]

Glad it helped, thanks for watching!

Thank you.

You're welcome! Thank you for watching!!!!

[@michaelanthony3964]

How deadly is muriatic acid to nearby shrubs? I'm thinking when I use it I will have to be very careful when hosing off or maybe neutralize first then hose down?

[@DecoCreteTV]

When diluted as it is in the application, normally you would not have any problems. It would not be a bad idea to hose down the shrubs afterwards though. Thanks for watching Michael!
