I’m about to use, with some hesitation, 5/4×6 meranti on a deck that is 12″ or less above grade. Can anyone relate their experience with a similiar situation, i.e. how the material expanded or cupped, gaps used. The distributors info leads one to believe that this material is quite sensitive to moisture and will distort accordingly.
thanks

I have used Dark Red Moranti Marked from Blue Star distributors nad have not had a problem with cupping or warping. We did treat the stock on all six sides. We also grade the area below the deck away from the house and then install six mill plastic with stone over the top to keep the area relatively dry.
Hope this helps

*Kevin thanks for the info. Did you screw the decking down. Also how close did you space the material. I normally space 1/8" and Blue Star is recommending 1/4" or greater. Seems wideAppreciate the helpJohn
