Transfer Paint Through the Strainer

What happens here

After a brief struggle with the strainer's fit, the user proceeds to pour light grey paint from the 5-gallon bucket into the hopper of a Titan paint sprayer, with the red strainer positioned over the hopper's opening. The paint flows through the strainer's mesh, but at an extremely slow rate, causing visible frustration for the user. He comments on the slow speed, noting that the holes appear to be 'straining' the paint too much, impeding efficient transfer.
