I do a bit of spray painting in the basement, when we hit the depths of winter. I bought a 36" dia grow light shade at a yard sale, $20. Put a hose to a small blower with a speed control and vent it out the dryer vent. A shower curtain hanging from it makes the booth. Takes about 5 minutes to hook it up. I just turn it on low when I'm spraying. You still end up with a bit of odour but not near as bad and it dissipates much more quickly. It definitely has helped with the shrieking noise that use to come from upstairs when I would paint.
