Concrete repair

[JohnMickish]

Ok, with all this talk here about new concrete and epoxy floors it got me thinking maybe it's time to do my garage.

I have a few spots (where the tires sit) where the 30 year old concrete has deteriated due to the salt accumulations and it's been eaten down maybe a half inch.

After a good cleaning with muratic acid what would be the right way to patch these areas?

Now this is only my advise. I would use a vinyl patch mix and concrete glue. If you want it to look the same, there are ways to color it slightly and I would use a sponge trowel to finish. The sponge trowel will blend area into same surface (aggregate texture) as surrounding area. It actually really works. All you major home improvement stores should carry all items. I would think if it is not to deep, may be epoxy floor patch would work as well. I have found out over year when filling and patching, it seems to hold up better when some device is affixed to existing concrete. If dip is to small for steel mesh to be fixed to it, just drill a couple of hole and bang a couple of Tapcon screw in it. The glue and vinyl patch will hold to just screw head, when you are in pinch.

The best would be Tapcon screw down wire mesh in damaged area. Good Luck! Have a great sunny Sat.

I would agree that there something other than a regular cement based patch should be used. Sika (not sure if I can post a brand like that or not) makes some very good products that I see on jobs regularly that can be feathered pretty thin. I'm sure there are other manufacturers too though. Unfortnately, nothing will stick very well and the best long term repair is remove and replace. Since I'm pretty sure you don't want to do that, I would probably look at scoring the patch area so you at least have a edge to finish up against.

You can get bags of premixed patching cement. The cement expert in the family recommends using Acryl 60 Cement Additive, available at Ace Hardware. I saw the expert do a patch job. He mixed up the cement and also included some of the Acryl 60 in the mix. He also painted the area to be patched with the Acryl 60 to work as a bonding agent.

You'll want the area as clean as possible.
