Jim how do you check the manufacture date of Kerdi Board? And where it was made?
Over at the John Bridge Tile Forum John Bridge himself writes that in 2008 there where defective boards with problems. How do we know our stock is not the old stock? How do we know that some are still not being made that way?
Could it be in the shipping? Maybe the containers get to hot when they are being transported in ships and trucks from Europe to North America, like a car does in the summer maybe???
Please let us know how to check when the Kerdi Board was made and where?
