My new favorite painting trick for removing lint in a Layered, Indirect painting is WINDEX! It lifts up lint between paint layers and prepares the new layer to accept the oil out “couch” without resist.
I squirt a bit of windex onto a makeup sponge, then I wipe a thin layer on my dry layer of paint (2 days dry), and rub with my finger.
It easily removes the lint/dust sitting on the surface, and with a bit of rubbing also pulls up lint from previous layers. It works as well as wet-sanding but without taking up paint. I used to use 600-grit sandpaper and oil medium on every layer, now I rarely sand at all.
Windex is also great with the problem of “resist,” when the new layer of oil beads up on a dry surface. The ammonia “etches” the surface a bit, so I apply a swipe of windex, let that dry a few seconds, and then apply the couch (oil medium layer, applied with a new makeup sponge), and the couch grips nicely.
It’s changed my life already - I used it just the last couple weeks of my most recent painting, and it lifted out tons of lint and texture. After the new painting dries in a few months I plan to swipe on a layer of windex before varnishing, so the varnish sticks.
This tip is NOT in my instructional video, because I just learned it, but I’ll be including it in future video lessons.
