    Q:Do you need to use more krud kutter on oil based paint? What texture is the paint supposed to be after the Hardner is added? I have some unknown or oil paint that I?ve added it to, latex paint turned chunky, the unknown paint still smooth & stir-able.

    A:  Happy to help, Jenn! Yes, oil-based paints will require the use of more Rust-Oleum Krud Kutter Waste Paint Hardener. This is because the absorption rate of hardener is reduced. - Rust-Oleum Product Support 3

      A:  No, I would not recommend. It didn't work very well for me.

          Great solution for dealing with old paint
          Works quickly to setup/harden liquid paint. Works faster than kitty litter and other fibrous products I've used. It also adds less volume to the paint can. Available in larger containers if you need to dispose of lots of cans.

          Lots of stored partial cans of paint leaving for dump thanks to the hardener. Its required that the paint be hard for them to accept it for the landfill. Amazed me that the paint stores that sold you the paint wont help safely dispose of left overs.

          It says for water and oil based paints and stains. I split up a 5 gallon container of old oil based deck finish and so far I’ve used 15- 3.5 oz bags and it’s stil not even close to hard. It thickened and became gritty but that’s it. Worked ok for basic paint.

          Worked exactly as stated. It dried my paint then it went in the trash. Saved me a trip the the dump’s recycling center.
