Thread: oxalic

    Default oxalic

    Good afternoon,

    what would be the longest a piece of stripped wood could go before it needs to be neutrilized? I will be stripping a deck on monday and will be starting with the ballusters and rails. should i neutrilize those after stripping or can they wait a couple of hours and neutrilize the entire project at the same time?

    thanks gents,

    EDITED,

    After more investigation I have come to the conclusion that i will neutrilize as i go. strip, wash and neutrilize ballusters and rails. s/w/n/ steps, stringers and hand rails, and so on. I am just not interested in leaving the stripper on the wood any longer than I have to.

    Either way would work fine Steven, I usually prefer to wait until after everything is stripped so I only have to brighten once.

    I've even come back the next day to brighten on one occasion when we ran out of time. Not the best idea to wait that long but it came out fine

    As I understand it, sodium hydroxide is active when wet, so if the deck dries, it stops "cooking". The problem is that, until neutralized, the SH will reactivate every time it gets wet - so you're OK unless it rains. A few hours? I wouldn't worry, though if there is any furring/fuzzing of the wood, I would neutralize ASAP.

    so does the ox actually stop the s/hydroxide from working?, hence the " neutrelizeing". and could you please elaborate for a minute on why to neutralize asap if the wood is fuzzed or furred.

    thanks Steven

    thanks Steven
    Yes, the oxalic instantly stops the SH reaction.It also brightens the wood. As for the "fuzzies", of the spindles - and I'm only addressing PT decks - are usually made with new growth lumber and have more of the softer heartwood - which makes them more susceptible to "fuzzing".

    Safety Note: When working with SH, if you get it on your clothes, rinsing with water alone will not stop it from eating your flesh. If I get any on me, I apply some oxalic, then rinse with water. I speak from experience that it's critical to neutralize the SH that you get on your skin or clothing. In a pinch, vinegar - even some soda that has citric acid will work.

    If you apply oxalic acid to your skin to neutralize the stipper, don't you have to worry about the effects of the acid itself on your skin?
