Best Caulk, For Concrete Floor Cracks?


I am actually redoing the garage in my own place. There are a number of 1/4-3/8" cracks in the perimeter of the concrete, either adjacent to the foundation wall, or due to settlement, over the last 20+ years, or just plain sloppy finishing. All of the cracks that \i want to fill are at the perimeter of the slab, not the center or driving area.

The floor isn't going anywhere, but we've had a bad year for insects, and visually I'd like to fill these voids, especially around, where our recycling bins are.


I'm looking for something that I can paint, but the garage also gets wet from the rain and snow. I don't want to use anything that will dissolve with moisture. What caulking would work best?

Thanks

I've been using SikaFlex and Duo-sil for sealants with great results. SikaFlex or another Sika product is made for that application. I think you can get Sika at HD in the mansonary department too.

Another vote for Sika products.

Don't know where are located, but I get my Sika products from Atlas Supply. White Cap in my area also carries them.

Thanks guys

I am familiar with the NP1

I honestly didn't even think of sikaflex. I used 292 to glue aluminum speed rails on the bottom of my boat. Amazing stuff. I'll check out their applicable product line, at a local concrete supplier

There's also, PSI-951 gun grade, I use this for control joints in wet lay brick and stone flatwork, or there's 952 self leveling.
PSI= Polymeric Systems Inc.

I'd personally use Andrews fast fix. It is a 2 part crack filler sets fast harder than concrete.
