I think it should be fairly straightforward, however I am wondering what products and type of paint etc to use when painting a carport ceiling? The area is outside and open so there is the roof and some wooden poles on the outside of the structure and there is no walls or doors. fairly simple. do i need to undercoat and seal etc? how many coats nd do i need an ecternal ceiling paint? is there a type of paint that is all in one like primer paint and top coat for external ceiling?
