First time posting.
Was directed to this site from the garage journal.
We have an in ground concrete SWG pool. The seal between the top tiles and the coping brick is broken (even missing completely in some areas). It LOOKS like the builder just used mortar first time around. It may have had a flex agent, but does not feel like it when I break a small piece out.
Of course, because of slight movement, the mortar won't stay sealed. I am going to dig out all of the old and reseal it.
What is the best product to use on this? I want something that comes in a caulking tube. I need to get this done before the weather (and the water) get cold.
Thanks in advance.
