When the primer is dry, caulk all small joints (less than ¼-inch-wide) in the siding and trim. Most pros use siliconized acrylics—paint won't stick to straight silicones—but Guertin and O'Neil like the new, more expensive urethane acrylics for their greater flexibility and longevity. O'Neil stresses that it's shortsighted to skimp on caulk. "If the joint fails, you're back to square one." Guertin uses the lifetime rating as his quality guide. "I don't expect 35-year caulk will last 35 years, but it should last longer than a 15-year caulk."
On average, expect to pay $0.60–$1.60 per square foot for exterior painting. The average for painting labor across the country is $30–$40 per hour before you pay for paint, painting supplies, location costs, and equipment. To get a very general estimate, though, painting contractors will take into account the square footage of your home and the number of stories and also factor in normal prep work.
Deciding which paint to use has gotten much easier now that acrylic latexes have pushed oil-based paints almost to extinction. The acrylics offer superior performance (they don't harden with age, the way oils do, so they move and breathe without blistering), they don't mildew as readily, and they emit fewer VOCs, so they comply with new air-quality regulations. They also work over both oil- and water-based primers. Thornton Home Painting
There have been instances of unscrupulous individuals pouring inexpensive paint into expensive paint buckets and overcharging customers. Make sure you have your painting contractor write exactly what type of paint products will be used to complete the job. Also, if you specify a brand, include that and the exact shade. It may seem silly, but making sure all of this is in writing will save you from misunderstandings and unnecessary obstacles to finishing your renovation. Thornton House Painters

All of that is compounded by the sheer difficulty, cost, and extended timeline for painting a home's exterior, making the question of the perfect exterior paint finish a critical one.
