Crack in the DECK at shallow end

[Bosco390]

Thanks, Marin!!.... the handrail is solid as a rock, and the crack seems to worsen only during winter when moisture gets in and freezes. I have tried to fill with rubberized liquid patch as you speak of in the past, but I think the crack is really deep, and the fluid just seeps down and never fills... perhaps a hole completely through? Regardless, I had NOT thought of attempting fill with sand first, and will most certainly try that. I am also debating using 2-part epoxy to fill the crack. I recall doing some boat repair years ago, and spilling some of the epoxy I was using for resin... it was there on the garage floor for years unscathed until I worked on getting rid of it. We'll see.

Thanks so much for the reply!!!

You're welcome.

Self leveling seam sealant will find every pinhole and sink into it. That's why we use sand to backfill and not backer rod.

My only reservation about the 2-part epoxy is that it isn't flexible. When the deck expands and contracts it will crack again. The seam sealant will allow for some movement.
