Hey all,

I have a piece of rebar that is exposed on part of my foundation its probably about 6" in length and goes along the length the foundation.

From what I have read online i should do the following steps:
1. Clean rusted rebar with wire brush and maybe some rust solvent to help
2. Seal rebar with some kind of epoxy. I was thinking this should be good. Krylon Rebar Green Epoxy
3. Cover rebar with some kind of masonry.

What product should I use for patching on top of foundation?

Is there anything else I am missing? I can handle this on my own correct?

Just imagine how 1/6 would've played out if DC hadn't had such strict gun laws.

You're heading in the right direction, though I would be less worried about sealing the rebar.

Most important part is to clean off any loose remnants of concrete where it fractured the beam. Then apply concrete adhesive (HD or Lowes) to side of beam and trowel or "paint" on a new layer consisting of Portland cement and sand.

That'll make it look better and slow down the deterioration for a while.

Thank you for the information! ok, I can get over the rebar part.

So really I need to

1. Clean area of any loose pieces
2. Paint on a coat of concrete adhesive
3. Put on a layer of concrete mix.

I see quikrete makes both products! From the little info I can find of these repairs is that it isn't really permanent but something that will be on going with the life of the house. I will try to get a picture of the area.

Try a construction supply retailer instead of Lowe's or box store. CMC in College Station is one example. You'll find high strength patch material and help on how to use it. Thin concrete patches with mortar mix won't last long at all.

Cut/ remove rebar, saw cut/ "square up" area, chip down about 1", and patch with non-shrink grout.

That's the kinda situation where you walk by it and think "I should do something about that. " A couple of years later you see it again and think the same thing. Next thing ya know 20 years go by and it's still there, unchanged. Made no difference, didn't matter.

Go in CMC and ask for a sample of "shep patch plus". It's made by Lyons manufacturing. It is a polymer and cementitious mix. Mix the 2 parts to a peanut butter consistency and float over the cleaned and prepped area.

I was in that industry for 13 years and the manager of that facility is a good friend of mine.

The only time it matters is on an inspection report and the buyers areally freaking out. We are talking 1960s ranch home in Houston. It's broadly been like that for 40 years now!

Ahhh, gotcha. That is a bit different. But the next thing that'll happen is someone will see the patch and be all over you about what you're trying to hide!

Good luck, sounds like you're getting good advice.
