ArmorGarage Dry Basement Epoxy Kit & Mastic

[LalaMoneyPit]

I am planning on using this to encapsulate the mastic and cover over with their epoxy. I came upon this product after having read that you typically *CAN'T* use an epoxy over old mastic.

They recommend using 2 coats of their "special primer", and 1 coat of the epoxy. I wasn't planning on adding chips. Would I need the topcoat anyway?

Has anyone used this product for this purpose? Now I'm wondering why is this primer and epoxy OK where most of the time, I've read epoxy isn't suitable for covering old mastic?

It also looks like they used a notched trowel to apply the mastic on my floor. The grooves aren't super deep, but I am hoping this ArmorGarage epoxy is thick enough to cover it over.

Here is the link to their page:

I was hoping this would be the easiest way to deal with the mastic. Also, I do like the look of a painted floor in a basement. I hate grout and tile and I worry about the longevity of vinyl tile. Carpet is out too because we have allergies.

How long will it take to cure so we can use the space again?
How stinky is this stuff?

Sorry for all the questions. This stuff isn't cheap, so I hope it's not a mistake.

Thank you in advance! I hope we're doing the right thing. We plan on selling this house. I hope it will be soon, but who knows how long it will take.

I think the typical "can't encapsulate mastic" is a truism.

Most mastic is some sort of adhesive and flexible and by nature does not work well with epoxy. Epoxy wants a solid grippy surface to adhere to. I am skeptical by nature, and even more so of "special primers" and single coating of epoxy. And expect it to do anything to preserve the other coating.

Even their directions specify etching the concrete, etc...nowhere does one see mention of trying to encapsulate or directions supporting your intended use....mastic covered floor.

Too many unknowns, and not enough real information, others may have specifics. But I would remove the mastic, grind/etch/prep the concrete and be done with it.

Thank you for answering, kd3pc.I read repeatedly what you write above. This is why this ArmorGarage stuff is tempting me.

I meant to include this link from their website. They claim that the example of a customer who DIY the job just directly went over the mastic. There is mention of using Bean-e-do, but they even recommend not bothering and just going right over it - "We would suggest you epoxy right over the mastic as this customer did in the images below."

Give their customer service a call. Many of these vendors are more than happy to answer your questions to make sure you get the correct product for your project.

Yeah, I'll give them a call to make sure, but my application is pretty much exactly as what is described on the website. I mean they're showing the guy priming directly on the mastic, which is what I hope to do.

My concern is this seems to be the *ONLY* epoxy/paint company claiming I can just prime and epoxy directly over the mastic. I was hoping for thoughts and opinions from an outside source.

I do know that ArmorGarage/Armorpoxy are well known in this industry so I would hope their claim isn't false. I would be thrilled if this really could work.
