Once upon I time I was a scene painter in the theatre and as such I had special paint brushes which I still own and use.
I prefer using the largest brush available that also suits the job.
Some of them are over 35 years old.
I’ve had these 2 brushes since college.
One of the most useful brushes of which I have 3 (or maybe 4) is a “lining” brush. In scene painting a lining brush is used at the end of a bamboo pole with a lining stick to make outlines and shadows. In its use at home it’s great for window frames and interior trim.
The black bristled brush is a lining brush although I also have one with light bristles.
I also have a few newer brushes (none newer than 5 years) which I use to paint trim, stripe in the boundaries of a wall (before rolling it) and furniture.
I love a natural bristled 3-inch brush.
When I dip a brush in paint I’m careful to keep the ferrule out of the paint although it sometimes gets up into it when painting upside down or overhead. I try to keep my brushes impeccably clean by rinsing them with cool water and brushing them with a wire brush after usage.
From time to time my good brushes need a few hours in brush cleaner to loosen hard paint near the ferrule.
I seldom use soap or detergent to clean the brushes. I do however have brush cleaner in which I soak my good brushes to loosen up any old debris. I rarely do this as the water and wire brush method seems to keep the brushes supple.
I pour the brush cleaner into the metal can (on the left) and suspend the brushes in the liquid with an aluminum foil cover. After the brushes are removed I put the can’s original lid back on to reuse next time.
When necessary, however, I pour brush cleaner into a metal can up to the metal ferrule and hang the brushes in the liquid for a few hours or overnight.
Every so often I have a lapse after which I soak the brushes in stripper then use the same water/wire brush method to clean.
Then I use the wire brush/water method, sometimes adding a bit of liquid detergent, to remove the oiliness.
My wire brushes aren’t pretty but they do the job of removing paint from the hairs of brushes.
Now my brushes are ready to get back to work.
Do you keep old things hoping to rehabilitate them one day? (I think I already know the answer to the question. HA!)
