PCR Hot start PCR - Mammalian DNA

A PCR reaction consists of the template DNA, two primers covering the amplification site, an enzyme, and buffers. However, non-specific product amplification and primer-dimer formation during set-up are major causes of PCR failure. Nevertheless, high-quality DNA polymerase and optimize reaction buffers will certainly lead to a successful PCR reaction

When should I add the polymerase for hot start PCR?

I keep getting a non-specific band in PCR so I would like to try a hot start PCR manually. How should I prepare the mix and at which step should I be adding the polymerase?

Hot start PCR using phusion green DNA polymerase

I am currently performing hot start PCR using phusion green hot start DNA polymerase in order to amplify a 8.8kb insert. However, I cannot get any amplified product at all. I have tried changing some parameters but I am not sure what to do. Any help?
