How to Fix a Crack in Concrete -- Quick Concrete Patch Fix - Sikaflex Patch

Small cracks in my basement floor/concrete slab are simpler to repair than I originally imagined. Few tools required, cheap materials, quick and easy process. Yes, there are better, more comprehensive, longer-lasting, and messier ways to do this... but this does the job of sealing and stabilizing a crack and works good enough for me. Maybe it will work for you too.
Tools used:
-- Knee Pads -- MUST HAVE! -- amzn.to/37Fkj2i
-- Wire Brush -- amzn.to/3E9V6ta
-- Margin Trowel -- amzn.to/3E5tcyh
-- Sika Flex (PREFERRED) -- amzn.to/3LYHljp
-- Top and Bond (Works fine too) -- amzn.to/37KbPqs

Is this waterproof?

[@polymaticfarm]

Well... concrete isn't even waterproof, per se, so not sure it matters much. I can tell you that it has accepted paint quite well, so if you use waterproof paint you're all set.

How did it hold up long term?

[@JustaJourneyman]

I have several of these repairs that are getting daily foot traffic for a couple years now and they are holding up just fine!

How would you best describe the dried, finished color? I have some cracks on my sidewalk which is fairly white.

[@JustaJourneyman]

It's a very very light grey-a lot like the color of the stuff when it's still in the bucket, but perhaps a little lighter.
