Sealing the bottom ?of a Redwood 'roof'deck

12 years ago

We just cleaned a newish -1 year old redwood deck that we constructed as pallets (a little more than a year ago) to set on our white torch-down asphalt roof. It's been weathering since then.

We bought the 5 gals of TWP stain. The question is - Do I, or should I stain the bottom of the pallets. Yes, I can flip them over as each one is about 7ftx 4ft.

The deck material is 2x6, and the sleepers are 1x6 planks, also Redwood...

The 'flat' roof has a slope and drains to a scupper. I live in the Bay Area (Berkeley) so it's mild most the year, with rain in the late Winter and Spring.

What say the experts and others?

I'm also tempted to apply this stuff with a roller, maybe 1/2" nap- any suggestions on the application method?

Next year we'll do the other roof and probably use Ipe.

I would stain both sides. It would undoubtedly protect the wood better, and I think this will minimize the chance of problems occurring because one side of the lumber is much wetter than the other.

I wouldn't use a roller. I've found that I can get a lot more stain into the wood with a brush. And of course, a brush is better in cracks and corners. Unlike with paint, where the goal is to get the thinnest, most even coat possible, the goal of staining is to get as much of it to soak in as possible without drips or pooling. A roller is better for the former, a brush better for the latter.

Thanks Gerard, that makes sense and we sprayed and back brushed the bottoms.
