Hi all,
Seems to me like everyone has his own idea...
Basic shrinkage as taken from Wood Handbook (Forest Laboratory) Sorry for that big image but it's important to know.
Below you can see two different options - heart down (left) and heart up (right).
If you install boards heart down you'll get a bowl full of water (whenever it rains) in every plank.
As I believe, the solution is to install planks heart up for two main reasons:
- flat planks - you can get rid of bowing by cutting grooves as shown
- strength - end grain has better abrasion resistance and will last much longer. And even more, using hard brush to remove sotf grain will make a great (nonslip) texture
Looking forward to see more in this discussion
Best,
