Q: Is TimberTech XLM decking slippery when it gets wet?

Any surface that gets wet is going to get more slippery to a certain degree, John.

To properly answer your question, we will need to get a little technical. First, a surface is considered “non-slip” when it has a coefficient of friction of .5 or greater. The ADA also has non-mandatory recommendations for a level surface of .6 or greater.

TimberTech XLM has a coefficient of friction of .74 when wet – which is well above the recommendation for being considered “non-slip.” We hope this helps answer your question, John.
