When hiring a painter it is very important to make sure he has enough experience to make the correct recommendations for your needs.
For example many painters have only painted residential houses so their product knowlege is very limited.
Many houses have galvanized flashing, it should be primed with a product called galvite to ensure the paint will last.
Ask your painter what galvite is, most wont know!
It is important that your painter have extensive knowlege of residential, commercial, and industrial painting. The crossover knowlege will ensure you get a quality job!!
