The Coating - Preschem Aussie Clear
If your wooden picnic furniture is badly weathered, wash it with a pressure washer, allow it to dry completely, and then sand with 80-grit sandpaper before coating. As soon as the wood feels rough or appears dry, apply another coat of Aussie Clear. The most effective method we’ve found is to use a general-purpose sprayer to apply a thick, even coat. After about an hour, use a tough cloth and work in a circular motion to remove any pooling on the surface. The surface should be dry enough to sit on after 24 hours. Not only is Aussie Clear Australian-made, but we also conducted independent tests—cutting boards into short lengths, coating them, and placing them on the factory roof for three years—which showed it outperformed all other similar products available at the time.
If Your Outdoor Furniture Stains Concrete, Slate, Pavers, etc.
This can look unsightly but is temporary. The staining fades quickly in the sun, usually disappearing within a couple of months. Once the furniture has been exposed to several rainfalls, the tannin will have leached from the wood, and staining will no longer occur. To prevent staining initially, leave the furniture out in the weather until it has been through several rainfalls. If you sand the furniture heavily, it may leach tannin again. We’ve seen a 100-year-old fence post, recycled into a table leg, still leach tannin onto concrete. Varnishes or kiln-drying will not prevent this staining.
