I have a crack which has developed in my front porch which I need to address. I'm planning on sealing the concrete, but do I need to repair the crack first? Even if it's something as simple as putting some sand into it to help hide it once it is sealed. Didn't know if the sealer would help it disappear visually or if there was another step I needed to do.
This is my first attempt at sealing concrete, so any and all help is appreciated, including any recommendations on brand, application methods, prep work, etc.
