When painting the trim, you don’t have to be neat. Just concentrate on getting a smooth finish on the wood. Don’t worry if the trim paint gets onto the walls. You’ll cover it later when painting the walls. Once the trim is completely painted and dry (at least 24 hours), tape it off (using an “easy release” painter’s tape), then paint the ceiling, then the walls.
I turn away any job when the client refuses to pay anything up front. It sends a red flag. I also charge a scheduling fee which is non-refundable. I get 33 percent when I show up and begin work. Another percentage halfway through, and the balance upon completion after client is satisfied. There needs to be skin in the game for both parties as a measure of good faith. If you are dealing with a reputable company (did your due diligence, right?) why wouldn't you want to pay something as work progresses? We do this not only because we love to paint but we require cash flow to stay in business. There is not always 'money in the bank' as you suggest. It's tough these days. The suggestion buy 'Kim' 'Never pay a contractor a deposit' is nonsensical. http://youtube.com/e/b6_WEt9k_Hw
If you paint over dirty, oily surfaces, the paint will easily chip or peel off. So before painting, clean grimy areas with a deglosser or heavy-duty cleaner intended for prepaint cleaning. They work well to clean painted, varnished or enameled surfaces to improve the adhesion of the new paint. They’re ideal for cleaning greasy or oily areas like kitchen and bathroom walls and removing hand marks around light switches and doorknobs.
