Bluestone walkway with joints recently redone
In late July I had the joints on my walkway redone as they were crumbling because I foolishly used salt in the winter. The contractor used cement mixed with sand for the joints, and then apparently topped them with polymeric sand.
What I would like to know is what kind of sealant do I need to apply that works for both the bluestone and the joints to keep water out? Obviously I won't be using salt any more but I want to make sure this lasts.
