Anyone have a reccomendation for a product they like to seal 1/4" cracks in poured concrete? Ive powerwashed the crack and chiseled the joint so its "V" shaped, now i just need something to fill it...

id think i want something fairly liquid since the crack isnt that wide and it flows into it, but it is on a slight grade, so not sure the self leveling sealants will stay put?

Self leveling compound is thin enough but its not that color. And, I can tell by the location and the variation on that crack that no matter what you put in there it WILL crack again. That concrete is moving and it always will.

If that is the only cracked area, you can break that section out between expansion joints but again, whatever you replace it with will look totally different. If you want to just keep the water out, get a tube of creme colored caulk from Home Depot and fill the joint and then chase the fill with a wet sponge to level off the caulk and clean the adjacent concrete. That's about all you can do...
