- Siding
- Trim
- High durability
- Harsh climates
A pro-grade, thick-film exterior acrylic that trades a high price for excellent durability and a lifetime warranty.
Pros
- Thick, flexible film resists cracking, peeling and fading in extreme weather, backed by a lifetime limited warranty
- Self-priming on sound previously painted surfaces, so most repaints need only one coat
- Good tannin-bleed and flash-rust resistance helps hide nail heads and wood bleed-through
Cons
- Premium price (roughly $60-93/gal) that is well above big-box paints
- Sold mainly at Sherwin-Williams stores, and list price is high unless you catch a contractor sale
- Bare wood, masonry and heavy stains still require a separate primer despite the self-priming claim
