Six years into my deck and pergola -- what I've learned
In 2013, I decided to try building a 21' by 20' deck. I did some online research and pulled the trigger on over $3,000 worth of red Brazilian Cumaru hardwood.
I'd never built anything like this before. And I decided to cover it with a steel-and-shade-fabric pergola. In retrospect, I really didn't know what I was doing. But I was lucky. Six years later, it's still there, still flat, and still a very nice place to relax.
Today I stripped and re-stained the wood. Biggest lesson learned? You've got two options with Brazilian hardwoods. You can let them go gray, which is what the smart guys do. Or you can re-stain the thing every year or two from now until the end of time. Foolishly, I've opted for the 'end of time' option. So since I'm six full years into it, here's a recap of what I did back in 2013 and what I did today.
It all started with a bunch of wood (950 lineal feet at $3.29 per) getting unloaded into my driveway. That was followed by clearing out my postage stamp of a back yard.
For the next picture, I'll jump through a few weeks of hard work to the point where I had all the decking installed. I didn't end up with a single length of wood to spare, which was probably a bad idea. And I opted for a floating type of deck, which spared me a lot of digging and (surprisingly) has turned out better than I thought it would.
Then I covered all the wood up and went to work on this idea I had for a cover for the thing. I started with the top part of it, since I didn't have any ladders that went up to the full height I had in mind. When I was done with the top section, I had to figure out a way to raise the whole thing up so I could weld in the lower section in. I ended up making a kind of mast with a hand-cranked winch to slowly raise the thing 8 feet up into the air. The good news? It didn't fall on me.
Jumping ahead a whole bunch again, this is the finished deck. I stained the wood with Penofin, which came highly recommended. As it happens, I wouldn't recommend Penofin to anyone. At least, not in California. After the first rain, my wood got a black-ish overcast to it -- probably a mold or fungus growing in the stain. Over several years of stripping and re-coating the stuff, I finally gave up on Penofin and switched to TWP's 100-series stain. Whatever fungicide it's got works MUCH better on my local fungi/molds than Penofin's formula. Where the Penofin would start to look bad after about six months, the TWP lasted a little over two years.
But eventually, even the better coating went gray. It's not a terrible look. And if I let it go completely, or stripped away the stain and let the sun do its work, I'd probably get a familiar shade of gray and I'd never have to move all this furniture again. But I don't like the way that looks. And it was getting pretty gray when I took a look at it two days ago.
Yesterday, I mopped it with a solution of Oxalic acid and water. Today, I applied a new coat of TWP stain. The difference is pretty remarkable.
I also added succulents to the planter boxes I built for the thing. I've had no luck with a few different types of flowers and other plants on this deck. So these succulents are made of plastic. The good news is that nothing I can do will kill them, ever.
I finished the new stain at 10:30 this morning (it only takes a couple of hours), but didn't count on the sudden rainstorm we got at 2:30. Fortunately, the stuff had dried enough that it didn't cause any problems. I just mopped the water up with some towels, and this is how it looked with the furniture moved back.
And for some perspective on how long the deck has been in place. Here's my son when I initially built the thing and again this evening. He wouldn't agree to smile either time. And he was more helpful when he was four.
The furniture has held up pretty well, too. It gets all the weather, but a little less UV because of the shade fabric above it.
And here the thing is after sunset, tonight. I hardwired a bunch of flickering LED candles and plumbed a gas line for a fireplace.
Day or night, it's a pretty nice place to relax.
