PLEAAASSSEEEE Help!!

[Sneaky Pete]

Hi guys... I been lingering the forum for a bit but this is my first post and I really could use some help..


I'm trying to redo my garage floor with the Quickrete 2 part Epoxy (with flakes).

My problem is that i have some other floor sealer on there and the instructions are saying previous sealers must be "completely removed" .

A friend of mine is saying that it should go on with no problem as long as the floor is cleaned off really well.

My questions are....
(1) will the Quickrete go on over the previous floor coating??
And if not...
(2) what do i need to use and/or do to remove the old sealer?


Any help would be appreciated

Thanks,
Pete

You probably need to scuff the old sealer with a floor sander w/ 60grit paper. You could however clean it up really well then mix up a few ounces of your epoxy and test an area and see what happens first.

called Home Depot and they said that all their sanders are for wood floors only.

The dude said Muratic acid is what they recommend but I already poured that stuff on the floor and didnt really notice a difference.

Sealers will have a tendency to "soak" into the surface. Epoxy needs something to bite into - the best being a nice rough concrete surface created by acid etching or shot blasting. If you do not get all of the sealer off, you run the risk of the epoxy pulling up over time. Unless the epoxy is designed to bond to the sealer in question, don't chance it.

I would see if you could find a concrete grinder or shot blaster for rent to remove the thin upper layer of concrete. Put some water on an area of the floor. If the water beads up, chances are the sealer is still there.

...oh and don't listen to a word the guys at Home Depot tell you. The only thing they are good for is directing you to the light bulbs.

LOL thanks man......My next 3 days off are starting Thursday so I will continue the floor then. In the meantime I will go to ACE HArdware and see if I cant rent somekind of blaster.

Thanks Again.

I would contact the company for a positive answer. Most have a customer service line or email that you can go to and get a honest informed answer. Hone Depot or Ace guy probably is going to tell you a hunch, but since it won't be theirs it is anybodies guess. From what my son in law told me about the options for my floor that there were some that if you put it down you had better not plan on being able to go over it with epoxy or other coatings.

An orbital floor sander will remove that sealer in short order...The sander won't know if it's sanding wood, concrete or jello!
