Hello, how can I help you today? Hi, I think Rick helped you out before but he's offline right now. As for the crack, yes, they're not too terribly bad to patch, the biggest issue is normally trying to match up the same surface that you have already with the new patch material. With any crack, you're going to want to open it up to at least a quarter inch wide and apply a coating of Acryl 60 bonding agent so the patch material and the existing surface will bond together well. What your biggest issue is going to be is that with most cracks, it's due to settling ground and sometimes even after you patch it, it may crack again on you if the ground is still moving, so you may need to do it more than once.
