Just bought some at Rona. Seems pretty good... wondering if ribbed side goes down or up? Label says in one sentence "On side with Lines." perhaps "Lined side Up" or "Lined side Down" would be more informative? Maybe either way works... not sure? Also... on a wooden surface such as deck stairs, maybe lined side down is sensible as it would allow the wood to breathe? So... in summary appears to be a great product with really vague instructions. Way cheaper than a broken back.See the comments section of this product »
