Rusting anchor bolts..

[BellyUpFish]

I just realized last year when I sprayed muratic acid on my floor to etch it, a couple of my anchor bolts must of gotten hit with the acid and are rusting.

So I’m considering throwing a couple more down.

Would you guys throw more down or just leave them?

I would think the acid bath would clean the rust rather than make rust. If you calculated how long the rust would take to impact strength, it would be a very long time. There is actually an advantage to using rusty anchor bolts (roughness improves bond). If you are designing a bridge where continuing salt is a problem and the stresses are high then epoxy coated is a advantage.

If you were closing in the walls I would for good measure. Otherwise not till they look deteriorated

That’s what’s got me considering it.

Finishing the walls.

I would coat them with a zinc rich primer.

Wash them off with baking soda water it will stop the acid. Then leave em alone.

I just put in six half inch x 6 anchors because my foundation straps weren’t close enough to the ends of the wall sections. Hammer drill and a couple new bits and I was done in under an hour. Cheap insurance to keep you from wondering
