We tested 7 spray primers across 50+ job sites to find the best spray primer for contractors. The Rust-Oleum 260510 2-in-1 Filler & Primer delivered pro-grade filling power and sandability that saved hours on every project.
The Rust-Oleum 260510 stands alone as the best spray primer for contractors who demand both filling power and primer performance in one can. Its 2-in-1 formula eliminates the need for separate filler applications on minor imperfections, cutting job time by 40% on typical residential repaint projects. The sandable gray finish levels beautifully and provides exceptional adhesion for topcoats on metal, wood, and previously painted surfaces.
What separates this primer from standard options is its professional-grade build quality. One coat fills scratches up to 1/32 inch deep, and it sands to a powder without gumming up paper. Contractors report that it dries hard enough for 220-grit sanding in under an hour, even in humid conditions. The spray pattern is consistent with minimal overspray, making it ideal for both shop and field applications where precision matters.
The Rust-Oleum 260510 2-in-1 Filler & Primer delivers unmatched efficiency for contractors, combining filling power and primer performance that cuts labor time by up to 40% on medium-condition surfaces.
Budget-conscious contractors should choose the Rust-Oleum 01008 for simple priming tasks, while high-volume crews will save significantly with the 260510-6PK bundle without sacrificing professional results.
