I installed my bamboo deck about 2 months ago. At least 10 of the boards on my brand new deck are splintering/becoming swollen to the point that they could be a hazard. I emailed calibamboo regarding the problem and they responded that it was an issue with the sealant (the deck had already been sealed using the stain they sent).
I have sent numerous emails after their initial response, but have yet to hear back.
