I've tried everything I know of. Heat, pressure, paint removers, acetone, scrapers, steel wool and more. Is there any chemical out there that will soften up STUCCO? ...it's on pavers, concrete, windows, terra cotta etc. I'm doing new construction homes, so HIGH pressure it out of the question! Thanks.

Amazing work as always, Al!

Did you get these rust stains out?

The X-Jet pulls via venture effect. You'll pull chems at 50% mixed at the tip. If you tried to get mine off the wand it's probably rusted on there and permanently attached... that's not from lack of use. It's from never taking it off!

Acids like HCL or HF not good for that. F9 will work. The only colored stuff we need to be careful of is poorly mixed colored concrete or pavers that are not strong. They use iron oxides in the mix that can get pulled out of the substrate hydrated too quickly. A weak bond between color and surface can be pulled out.

F9 on that all the way. 1:2 ratio, barely mist it on.. call me if you need further help. Easy.

F9 will work for that. Use normal solution and a very light mist coat. It wont etch it like one restore.

Ryan, so many variables here. Was it F9 you used or another chem?

Excellent to hear. Nice job.

I've heard muriatic (hydrochloric) should have a very long shelf life as long as the cap is on really tight and no vapors escape. Very long as in 10+ years!

It's always good to not put all of your eggs in one basket. For F9, we have many target markets that can use the cleaner. With that said, my primary alliance is with keeping the product for professional application only. Whether this be through our F9 Professional Applicator network, contractors or maintenance department training. This keeps the product in the hands of the most capable companies and who are worth the time investment of training, technical seminars, online videos etc. Also, since I own a pressure washing business and it is something I thoroughly enjoy, I feel good about giving information and leads to companies who are truly appreciative of the information and receptive to learning new applications and techniques.

HF can be dangerous stuff if not handled properly. F9 is not HF, does not contain any EPCRA section 313 chemicals, has no halogenated hydrocarbons, is biodegradable and will not bioaccumulate. I do agree that HF can make a great rust remover as well as Oxalic but users of these chems need to be aware of the dangers with unbuffered or uninhibited acids. When handling and using these types of chems, always wear an acid-gas respirator, gloves, boots, eye protection and full body protection. As usual and even when using any acid (or caustic) based chems we would recommend the use of rubber gloves, boots, eye protection and skin protection.

I've been through them all too, which is what inspired me to keep working on F9 through the years. I can't tell you the 1000's of tweaks we've made to make this work for us and our environment. Our clients are very picky here and we've made them all very happy with our cleaning techniques and how clean we can get things. I'm glad we've come to a point where we can help others get the same results!

Wow.. Thanks for exploring and finding new uses!

Here are the application vids. How to remove battery stains on a driveway How to remove rust on pavers How to remove rust stains on concrete from metal How to remove rust stains on stucco How to spray from control joint to control joint How to dissolve the crystals in a BARC bottle What kind of sprayer should I use The difference between white and orange battery stains F9 Applicator Video Acid wash pool

Looks great, Jeremy!

Amen.

Job Lead in Reno, Nevada... need an applicator ASAP. PM me if you are interested. Thanks.

If you have any questions let me know... Thanks.

Thanks, John. Our philosophy is to always under promise and over deliver. F9 is the Ferrari of restoration chems and I take it into battle with me often! .. And we win :)

This is a job we did a few months ago. There are so many different (BAD) things going on in this picture. Do many of you come across hard water stains like this? By looking at the picture what do you think is happening with this concrete?

The silica in shoe boxes is different than the reactive aggregates sometimes found in concrete. What you are referring to in shoe boxes is silica sand. The reactive aggregates in concrete are mostly formed from argillite, greywacke, chert, quartzite, opal and strained quartz crystals. The reactive rocks are supposed to be screened for at the quarry but sometimes make it through. In the core samples all we looked for was silica gel.. no need to diagnose the rocks. Once we know that there is a reaction between the hydroxyl ions in the alkaline cement pore solution and a reactive form of silica in the aggregate, then case closed. So, as far as sealer goes there are some lithium sealers that work fairly well. These are super expensive and no one would be willing to pay for it in the work that we do.. like upwards of $200 a square foot. If you put down a breathable penetrating sealer it can help to slow down the reaction but most still have a 2% vapor transmission rate so water vapor can still escape. Basically, if you run across this type of concrete you can clean it but that's about it. A penetrating sealer will help and you can even tint it, but within a short time the aggregates will release their fluid and still permanently stain the penetrating sealer. If you want to learn more, here is a 90 page article on the basics of ACR's: http://books.google.com/books?hl=en&lr=&id=p8--3BiBbYMC&oi=fnd&pg=PP1&dq=alkali+silica+reactive+aggregates&ots=TDKVnWWmuK&sig=912i9YE1ieo3rm57qJccSsP_hrs#v=onepage&q=alkali%20silica%20reactive%20aggregates&f=false

F9 will not hurt it, in fact we use it and so do many others to clean painted surfaces, sealed concrete, coatings and even painted wood.

Can you post a picture?
