A bleach-and-water mixture is alf you need to kill mildew and remove its distinctive color. Removing the Dirt Once the mildew is gone, what's left is good old-fashioned dirt. I like to use TSP or the more environmentally friendly TSP substitute to remove the grime, but you can find special deck cleaning compounds in the deck coating aisle at your building supply store. All are safe for the existing finish, but strong enough to do the job. Mix according to the directions on the label and apply with a scrub brush and some elbow grease. Do a section at a time, and rinse with the hose to make sure you've gotten all the dirt off. If you own a pressure washer, now's the time to haul it out and prove to your spouse that you really did need to buy it. Set it on low power and wide fan; a strong pinpoint blast from this tool can peel back a layer of wood lickety-split. Even without cleaner added, a pressure washer can make short work of surface dirt. However, most of these rigs have either a hose or compartment that can add concentrated cleaner to the water stream for a more thorough scrubbing. You'll find compatible deck and siding cleaners in the pressure washer aisle of your local home store. Taking the Gray Away Sometimes it seems the only thing turning gray faster than your hair is your deck. That's an indication that that area is unsealed, because only raw wood goes gray. Fortunately, you can easily reverse it without damaging the finish on adjacent, ungrayed areas. Buy special gray removing concentrate or a container of oxalic acid and mix it according to the directions Woodworker's Journal June 2002 on the label. Wear a dust mask and goggles when mixing oxalic acid powder as it is a toxic irritant to mucous membranes. Flood the mixture 011 the entire surface, grayed or not. I.eave it alone until it dries, then hose it down thoroughly to remove any acid residue. Stripping Old Finish Decks that are recoated regularly may never need to be stripped. But if for whatever reason you decide to remove the old finish and start fresh, be aware that you are in for a tough task. Special deck strippers sold in the deck coatings aisle will do the job. Wear gloves, old clothes, and rubber boots. With a synthetic long-handled scrub brush, wet a small area at a time; no more than 10 square feet. Reapply if you must, but keep the stripper wet for at least 15 minutes, or until the finish softens, then scrub to loosen it. Rinse away the dissolved finish and move to a new area. Be careful, though; this stuff gets VERY slippery. You might want to duct tape sections of old 40 grit sanding belts to the soles of your boots for traction. Applying the Sealer or Stain As always, preparation is the hard part. Now comes the easy part. The only challenge is to apply the coating as uniformly as you can. Choose a day when the weather is going to cooperate with you. A calm, warm, dry, slightly overcast day is best. Strong winds can blow dirt into the finish, and few things are as annoying as watching an uncured deck coating gel destroyed by rain. Cold continues on page 80...
