    Re: Caustic Soda

    I was comparing the caustic to American Building Restoration's (ABR) Fast Finish Remover. This is a Potassium Hydroxide based stripper/remover and has 19% Potassium Hydroxide according to the manufacturers MSDS on their website. They recommend that it be used 4 parts water to 1 part FFR. Therefore, the operating % is recommended to be somewhere @ 3.8% if my math is correct. Now I cannot figure out the math for reducing the 50% solution to that level when mixed with water, although I estimate that it would be 2.5 times what the FFR was, so 10 gallons water, 1 gallon of 50% solution caustic or am I way off on this?? Some of the chemical math wizards should chime in here.......

    Who lit up the bat signal...

    Without the labels, I'm having to assume it's 50% w/w and not a 50% cut of what it was in a bigger container. That said;
    Russ's hot mix is 13.1% His normal mix is 8.8%. Mix your liquid about 1:3 for hot, 1:4 for normal.
    Scott's mix is about 6.25%. Mix your liquid about 1:7 for this strength.

    IIRC, Potassium Hydroxide is used at different rates that SH.

    Re: Caustic Soda

    Philip, thanks for sharing, last question tho...is that an x-jet-able mixture or would that be "pumped" or "sprayed" at those ratios?? Thanks again, Mike.

    All of those mixes are xjettable.

    I think it is good for all of us to use this chemical where ever possible

    I've too found the caustic soda beads. Believe it or not, 1 phone call was all it took, and I'm STILL trying to find 12% SH
