Hi Judith, thanks for your feedback. We have no affiliation with Sherwin Williams. This is based off asking 12,000 of our painting contractors what they think the best paint is. Peeling can result from low quality paint or from poor prep-work. While the paint you use makes a big difference, I don’t think it can be blamed for peeling after a year..that has to be on the prep side.
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." Westminster House Painting
