Hi - You've probably answered this question before but I did not find a message that is related.
I have cracks in my sunken living room floor. I plan to use Quickcrete vinyl concrete patcher to fill the cracks. However, I did see concrete patcher in tubes that can be used with a caulking gun. It seems this may be the way to go in order for me to inject patching material much deeper into the crack, is this a good way to go VS the vinyl patch material? Also, if I use either material should I first treat the area with a bonding adhesive before patching the crack?
