Patching before Etching?

[ae82gtm]

Does anyone know if it is OK to patch first, prior to etching?

I want to know if this is an option.
I have started my epoxy project for this weekend, but cannot get one oil stain out (9 month old floor, one stubborn spot). If I can patch tonight instead of etch, it may buy me more time to try another approach at the stubborn oil stain.

I am planning to use Rustoelum's epoxy patch.

Anyone know or have experience in this matter?

Thank you!

No, it is not a good idea to patch before acid etching your floor.

What methods have you used to remove the oil stain thus far?

Hello Benwah,

Rustoelum degreaser. Tried three different times. Fully concentrated with scrubbing.
Also Valspar Oil Stain Remover (like pour-n-restore) now drying on second application.
Any other recommendations?

I also called Epoxy-Coat and tried to get some advice. They mentioned that if the stain isn't coming out, I can apply some epoxy first in that area, as a primer. Then put on the base coat. I mentioned that I was going to use primer anyway, and they mentioned that would work as well.
It relieves me somewhat to hear that, but of course I would want to get rid of this stain first.

This may be an unconventional method, but brake clear works pretty well for removing stubborn stains. Saturate area in a pool of brake cleaner and then scrub it a bit with a hard bristle brush or broom. Also, use a pressure washer to wash away. I find oil stains are pretty hard to get rid of without a pressure washer.

Some people use plain old Simple Green too. Saturate and let sit 5-10 minutes, scrub and pressure wash away.

EDIT: Either method may take multiple cleaning to remove stain.

Lightly sprinkle water on stained area, once water absorbs into concrete and no longer beads you should be fine. When applying a prime coat, thin it down 10-20% so it penetrates the concrete more.

Thanks for the reply. I will pick up some simple green and brake parts cleaner on the way home to give it another shot.
I have also been using a pressure washer.

Thank you very much for your suggestions!

Bad ones can be ground back to good material and then patched and ground level.

Bumping up a slightly old thread here.

I just did a bit of patching before I was ready to etch and then that thought crept into my mind. I am using Rustoleum's product so I gave them a call.

They told me that I should have etched first, but if the patches are completely dry before etching, I should be ok. She told me this AFTER I asked, "did I just waste $100.00 on patch and make a lot of horrible work for myself?"

They recommended 8 hour dry time before trying to etch, but I'm going to be waiting over 24 hours anyway.

I was really hoping to find someone here that patched before etching, to know how it worked out for them. Rustoleum was helpful, but they still didn't give me a warm fuzzy feeling inside.

It's all about chemical compatibility and if the company said the acid does not react with the patch, then just go with it.

I just want to know if anyone has had experience with it, because as I stated in my last post, originally she said that I should have etched first, but then she said it SHOULD be ok after I already told her that I patched. That didn't sound like the biggest vote of confidence to me.

Lot more to the conversation, but to much to type. That's why I'm asking.

Hopefully someone has done this before?

if it helps,
I am/was at that stage..

I decided to etch first, next I doing some patching,
then I have to put some oil spot primer.

I think ATEOTD I dont wanna scren up nearly $400 worth of (epoxy) paint,
famous last words is "should" be ok.

I would always play it safe

The problem is that I already patched, that's why I was asking if anyone has done it that way.

I have no idea how it's going to turn out, because it seems no one here has ever done it that way, so for better or worse, I'm going to etch this week and see if I wasted a bunch of money or not

Sorry, I didn't mean to be a smartass or anything but chemical compatibility is very basic especially if you received info from the company's tech.

No worries.... I never took you as being one anyway. I know sometimes it's easy to get taken out of context online, so I never sweat the small stuff.

Anyway.... I just got in from etching the floor, so I'll be letting it dry for a few days and I'll report back.

Local weather is going to be in the high 80s and low 90s for the rest of the week, so drying shouldn't be a problem. If all goes well, I'll be coating the floor over the long holiday weekend.
