Acid etch before 4500/8510 question

[purediesel]

So a few months back I seen in a thread a suggestion on a mild acid etch before applying the 4500/8510 process, but now I can seem to find it. I've searched so I thought I'd just ask. My slab is now ready for the 4500/8510 but my problem is that the contractor has sprayed a slight coating of Euclid diamond clear cure n seal coating. Some places its hardly noticeable while other spots it was spilled quite heavy and is still very apparent that its there. I've read that a mild acid etch will help remove this coating and provide virgin concrete for the 4500 and 8510 to soak into. What I need to know is what kind of acid is suggested and at what percentage is recommended?

Thanks

You can't remove it by acid etching. Acid etch is not a coating remover. It reacts when it comes in contact with the free lime in bare concrete in order to etch it. You will need to remove it either by mild grinding or using a solvent-based stripper. Euclid states what it requires to remove it in their data sheets below.

I was told acid would work. Looks like EUCO Clean & Strip is made to remove their cure and seal. That'd be fine with me. I'm not grinding 4000 sq ft. If that was the case I would have bought epoxy not 8510. Thanks for pointing me in the proper direction.

If you would like to send me this information via email I will get you a straight answer in writing from the manufacturer. Grinding will cause other issues. Etching can as well but I believe we can find a solution for you

Hi
Just make sure that your floor is absorbent when you are finished removing the sealer since Ghostshield is a penetrating sealer and must be able to be absorbed into the concrete to work properly. You can test by dribbling water on it in spots, especially where you think the sealer was put down thick.

Hey Justin, what info do you need? If possible I'd like to get moving on this 4500/8510 job. It's getting cold fast here in Ohio. The cure and seal used was Euclid diamond clear. I've performed an experiment and acetone will remove the sealer as will other solvents. I'm actually leaning towards a mechanical removal using a floor machine and a sanding screen, stripping pad or maybe a dimabrush around 100 grit or so.

Can you drop me an email with all this above and all the project specifics and concerns. I am going to involve the manufactuer. I do not like creating a profile for sealers and I want to make sure we get you the best info possible
