Posts Filler
I filled in these cracks with 3/8ths backer which allows me to use less caulking to fill in. These posts were damaged by the sun, with the pergola not providing much protection & shade. You can see the pergola in full view below. The key is to be patient as you apply the caulking so that you don’t end up with smudging or a “hazy” look surrounding the filled in area.
