I built a cedar above ground planter last summer for my mother-in-law, and one of the sides didn’t hold well. I used pocket screws to secure the sides to the posts - but one broke out (pic below)...
To fix this, I was considering filling the void with some sort of adhesive and then simply placing the board back into place. Once the adhesive cures, it would be nice and solid. But I’m not sure what would work well(if at all).
What type of adhesive would work for that? Or is there a different approach that would work better?
