How To Repair Split Deck Posts
Outdoor structures are exposed to heat, cold and rain, which causes the expansion and contraction of the timber, creating cracks and splits.
Cracks continue to move with the weather, so these areas of damage and any timber joints in the deck that have opened up should be filled to avoid additional moisture problems and insect infestation.
If old posts are cracked, check for rot before filling or replace posts if they are not structurally sound.
Sand and oil the area once the filler has cured to prevent further damage from occurring.
