new Ipe deck problems
I installed an Ironwood Ipe deck last summer. The deck is 16" to 18" above ground on pressure treated Doug Fir with good ventilation. The boards arrived pretty marked up so I sanded (120 grit). Following the conventional advice, I sealed all cut ends with Anchorseal, being careful not to get the wax on the flat surfaces. I sealed the deck surface (all four sides) with Transparent Redwood Penofin as it was one of the top recommendations by the Ironwood folks. Despite my care in sealing the cut ends, the wax appears to have soaked into the wood to the point that there is an inch or more of discoloration at the ends of many of the boards. The wood turned silver during the winter (before it stopped raining) and now it has mildew stains. I'm planning to use dilute Oxi Clean (non-chlorine bleach) to get rid of the mildew, sand again with a coarser sandpaper (80 grit?), and apply more Penofin (I still have three gallons from last summer). I hope that will eliminate or minimize the wax stains. Any other suggestions? A better cleaner than Oxi Clean? Better stain/sealer than Penofin? All advice appreciated.
