@Racer just wanted to clarify its 6-8oz per cup of water?
No- just 6-8 oz per gallon. 8oz is 1 cup, So basically 1 cup per gal.
ok thanks for the clarification. I just ordered a 10 lb bag of it.
Apple cider vinegar performs the same function as oxalic acid? If so, how do you mix it... do you just add a cup per gallon of water and spray it on?
I do 50/50 and ds
Reading up on wood work tonight. I've got a nasty deck tomorrow. I'm still only downstreaming and I'm using 10% SH. I'm planning on mixing a 5er with straight SH and my soap. I'd like to add some hydroxide (powder lye) to the mix too, but I'm not sure how much would be a good amount. What are your thoughts? Here are a couple pics of the deck.
going to be some great before and after pics
Whatever happened to that deck. Where are after pics?
Shoot. My bad. It turned out great.
Checked it 1 week later and there was some furring but not too bad.
what was your mix?
In a 2 gallon pump sprayer. Less than 1 gal 10% SH. 1 cup sodium hydroxide (lye) couple squirts of dawn. Wet wood. Applied. Waited 10 mins. Rinsed. Post treated with oxalic. 1 cup/gal in a DIFFERENT pump sprayer. Don't mix them. Ever. You might die
No offense, but that deck doesn't really look great to me. The wood looks really dark. Is that after the oxalic? I've only done a handful, so maybe it's just me.
Yea that's after oxalic. It has a natural look. Not bleached out like some of the decks I've seen. It's all personal preference. The homeowner and I were pretty happy with it. It was covered in algae and slick black nastiness for no telling how long.
Can I see some of your wood work for reference?
Heh. I'd take a look, but I'm in Donying, China at the moment!! I used brightener on 2 decks so far, but it was the Sherwin-Williams liquid brightener.
Yea when you get a moment thatd be great. I like checking out different work and methods. Also, this deck is completely shaded with no direct sunlight except for the front steps.
