Trex

the mold in trex has nothing to do with pine trees or the weather. it comes from moldy wood chips used in the composite durung manufacture and ther is no treatment short of replacement. Trex denies any wrong doing and do not stand behind thier product. I t will occur even on south facing full sun exposure Decks. It is internl in the product. Donot I Repaet do not ever ever install a trex deck
