What is the best concrete patch product?
what is the best product to patch cracks in my grey stamped concrete patio? They are not wide, but they are extensive (poor quality job, but making the best of it). Slab is supposed to be standard depth, and probably is in most of the patio. I live in southern california, so doesn’t get below 20F and temperatures can reach >100. Not subject to great amounts of water. I am a pretty handy gal, so any tool requirements/recomendatons are also appreciated. Thanks!
if they arent that wide and you dont get much in the way of freezing temps, i would try to live with them…if you think the cracks look bad, wait till you patch them…if they really need patching i take a grinder and diamond wheel and make them wide enough to trowel some portland cement and fine sand into the crack and then hard trowel it…
