- I’ve settled into a pattern of filling one of my palette wells with dry talc. This is so much more convenient than opening a bottle every time.
- I use a wet brush to pick up some talc and mix it with the paint. I’ve also found that it’s not necessary to clean the brush beforehand. The talc sticks to the paint and the talc left in the well stays clean. This is a very useful property
- I’ve also found that the easiest way to matt a portion of paint is to add two or three “dipped brushfuls” of talc. I stop adding talc just as the paint starts to look like a paste. I then thin the mix with just enough water to make the paint flow again.
It’s really far too early to tell if this affects the adhesion properties of the paint in use but I haven't experienced even the slightest issue so far.
Finally, I’ve have treated whole bottles of paints but I’ve been careful not to add too much talc. I tend to add just enough talc so that I only have to add a final touch extra when the paint is on the palette. I’ve also erred on the side of caution and added some matt medium after the talc just to maintain the fluidity of the paint in the bottle. By the way the matt medium does not flatten the paint on it’s own: I tried that first!
