All the stuff I find at HD/Lowes for patching concrete cracks at intended for a maximum size of, at most, 1/4" wide cracks. I have some very wide cracks/openings to patch, and I'm looking for product suggestions. (I asked this earlier with a different title, and attracted no responses. That surprised me, and I still wonder why.)
Anyway, her is my situation: 27 years ago my concrete patio was poured. 2" x 4"s were used to divide it into four large areas. Patio has served me well. 2" x 4"s are beginning to rot, and slots are developing in the patio where the 2" x 4"s are. I'm considering just pulling up the remaining 2" x 4"s and filling the cracks with some sort of "gunk" I could purchase at HD or Lowe's. My expectation is that the "gunk" would generally match the color of concrete, be smoothed to be level with the rest of the patio, and that it would harden in a few hours/days. Question, what is the best type/style/brand of "gunk"?
Any other ideas?
