With TWP, the manufacturer recomends two initial coats, "wet on wet". Not sure how one is supposed to do that, but what I did was first coat, let dry and let the sun beat it up some, then second coat about 6 weeks later. TWP 100 series is a resin based stain high in VOC's. It sticks very well to wood as well as itself. In six weeks the sun started to bleach out a small portian of the deck so I thought it was time to add the second coat. That was two months ago, and the second coat really did the trick. The sun so far has not faded any of it. Everyone asks what kind of stain I used as the rain and pool water simply puddles on top of the deck and waits to evaporate. Kind of hard to find, only one paint store in Michigan carries it, so I simply ordered it on line. About $23 per gallon. Used slightly less than one gallon for first coat for a 300sq ft. deck. The second coat only used a little more than a quart. Very happy with this stuff. I have some pics in my phone, will try to upload them later. They have six colors availiable, and they can be mixed together for a custom color if you wanted. South American hardwood can seem a bit intimidating to work with, but it really is not. Just follow John Hyatt's posts on Gardenweb.com and do what he says.
