Generally speaking, a gallon of paint will cover about 350 square feet. If this is the first time drywall is painted, it will soak up more paint. And remember to factor in whether your job will require one or two coats of paint. Dark and bright colors will require more coats of paint, as will painting a lighter color over an existing darker color. Divide the paintable wall surface by 350 to determine how many gallons of paint you will need to buy. If there’s an odd number with less than .5 leftover, round down, if it’s over .5 round up.
I have used Flying Colors in the past for roof cleaning and refurbishing and painting my cedar siding. They did an excellent job then so when damage was done to my roof due to a fallen tree I immediately thought of them. I called and within a day they had someone out covering the tree and hole in my roof with a tarp to prevent rain from doing further damage. Then I needed to do serious tree removal throughout the whole property including the roof, but as soon as that was done, I called Steve Totilo the owner and within 3 days he had a crew working on the repairs and reshingling which were done in short order. The work looks impeccable and I would never hesitate to recommend him for any outside home repair or painting you might need.
