How to repair water damaged outdoor shed?

[saurx]

Looking to salvage our outdoor wood shed (3m x 5m) that has already been built in the backyard. The existing internal wood wall panels and ceiling panels has some water damage. What materials would you recommend to replace the rotten wood panels for the walls and ceiling for better waterproofing and longer lasting?

Hello @saurx 

Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your question about repairing your shed wall.

Before you replace the panels of your shed wall, I suggest addressing the source of the leak first to prevent the same thing from happening. You can use either use Selleys 290ml Grey Storm Waterproof Gutter And Roof Sealant or Fastfix Wet Shield 1kg One Coat Instant Waterproofing for large areas. In regards to the wall covering, I suggest using plywood or STRUCTApanel 12 x 2400 x 1200mm H2 Structural Panelling.

If you need further assistance, please let us know.
