Thermally Modified Ash after 8 months exposure with Cutek Extreme on 6" only
This shows the surface of thermally modified Ash decking treated with Cutek Extreme at 1 end only (6"). Boards were placed in full southern exposure for 8 months. Note how the board is more tan looking due to it protecting against black mold growth. Also note there is significantly less surface checking and cracking where Cutek Extreme is applied.
