u/PhraugPaste

Hi all,
I was wondering if anyone has mixed powdered laundry detergent with white paint to achieve uv reactive paint in volume. Laundry detergent has optical brighteners in it. I remember mixing it with a little water to make a uv reactive paste. I’m going to try you mix it with paint. Any suggestions, experiences would be greatly appreciated.

It’s a larger wall so I need volume and a lot of the stuff I have seen has been splotchy.
