I recently rebuilt my front stairs about 8 months ago and used mahogany decking for stairs and decking. Just recently it started buckling. I sealed the deck when first installed with a quality sealer. I've read from a blog that you should seal all sides before installing, but then I think you can't keep sealing underneath after installation. I've also heard about end grain sealant to prevent buckling.
Doe anyone have experience with this and know how to fix the problem so it might unbuckle and prevent it from happening again?
