Our new home has maintenance free siding, trim, windows and doors. However, we decided to “splurge” a bit on the decks so we installed beautiful Cambara decking (Cambara or Erbina uncinatum is a beautiful hardwood with straight clear grains similar to mahogany). In fact we installed the Cambara on the farmers porch and the large rear deck. Needless to say this has left me with a significant amount of wood to maintain (over 1,500 sq ft).
Cambara has a natural reddish color. If you look at the adjacent photo you’ll see that our deck has a very dark brown to black color. This is a result of the mold that’s been growing on the decking.
I’ve decided that I need to remove the mold and try a new deck sealer. The best way to remove the nasty mold growth is to use a pressure washer. I’ve been wanting to buy my own pressure washer for some time now so I finally went out and bought one this weekend. Thanks to the guys over at One Project Closer I had a nice Home Depot gift card so I ended up buying a new gas pressure washer (I’ll write a review on it after I’ve used it for awhile).
The key is to go slow and keep the pressure washer nozzle a constant distance from the decking. If you’re not careful you can create really bad gouges and defects in the decking. It took me about 2 hours to completely clean this 24 ft long by 8 ft deep deck.
I’ll be writing at least one more post that focuses on refinishing the Cambara decking. The previous sealer (Penofin) was horrible. This deck is only 3 years old and it’s been sealed twice with Penofin so I need to try something new. I’ve actually decided to take the “One Time Challenge” and apply a deck sealer that claims to last 7 years! So stay tuned in the coming weeks for my review of the One Time product.

1,500 sq ft! Wow, that is a lot of wood to maintain. That's bigger than our house. But it is a lovely wood, though.
I am sure it will be wonderful when you are all done. It looks like a great space to enjoy your summer.
Todd, what a fantastic result! I too have a Cambara wood deck that I installed myself last year. I'm sharing this because after just 1 year there are patchy areas of mold (black fungi) appearing and it bugs me. Not just because of all the effort installing and treating (with Penofin I might add), but because of all the great pictures and promise of what a Cambara wood deck looks like and I'm not able to achieve that. Our conditions are a rooftop deck in Boston therefore 24x7x365 exposure to the elements and of course all 4 seasons. I chose Cambara for the look, ease of maintenance, and ability to exist in damp conditions. Using Penofin Finish for Hardwood {which they claim is used for all fine hardwoods such as IPE), I treated each board on 3 sides (+ ends) prior to installation and once installed, applied to the topside 1 initial coat and a 2nd coat ~3 months later. Last year the deck looked great. This year the color of the deck has darkened considerably and there are black mold patches everywhere. Wondering your thoughts and conditions and also how did the 'One Time Challenge' turn out?
@ Jerry - Well with the rain we've had this summer I've yet to try the "One Time Challenge". I'm waiting for things to dry up here. I think the problem is Penofin and I'm hoping that a different sealer will cure this. Be sure to sign up for my RSS feed so you'll know when I finally seal it.
I have part of my deck that get's no sun to dry out. How it is green and black..How can I keep this from happening
NOthing you can do....it will need to be cleaned often.
