Off hand I don’t recall, when I get moving again, I’ll dig it up…
I used a lot of TiO2 with the water, but it ended up being a slightly heavy slurry that would work in my air brush. It separates in water and alcohol. It’s also difficult to apply evenly. Water doesn’t stick to the tile so it’s just surface tension… also added a few drops of red food coloring.
I’d suggest using something like the white acrylic that has TiO2 in it and adding more. I’m using that at the moment with the fiber… too hot for the co2, which is in the garage…
I seemed to have better results with about twice the TiO2 in the mixture… I use a HVLP spray gun from harbor freight.
