Only experience Josh. A plasterer can render a complete gable in one go whereas a DIYer can take a month. There is nothing you can use to slow the process down without damaging the integrity of the render.

when we render big areas ,50m plus , we put two coats on the wall , first coat is a scrath coat with a waterproofer mixed in the gauging water this will allow time to work with the second coat , float coat , but as said timing only comes with experience
