Multi-Purpose Interior Oil-Based Primer

Description

Secure an impenetrable, uniform foundation layer across challenging indoor surfaces with Sherwin-Williams Multi-Purpose Interior Oil-Based Primer. This professional-grade alkyd undercoat is engineered to solve surface adhesion and active stain bleeding issues across residential, commercial, and historical renovation properties. Formulated with stain-blocking resins, it isolates and locks down bleeding contaminants from water rings, ink markers, grease splashes, tobacco smoke residue, and active wood tannins on raw trim. It features exceptional penetrative adhesion, making it an excellent choice for priming bare pine, cedar woodwork, plaster patches, and previously painted surfaces that have become glossy or slick over time. The heavy-bodied alkyd formula controls suction on porous surfaces to ensure a completely uniform topcoat sheen holdout, preventing blotchy finishes or “shadowing” when applying your final decorative latex, acrylic, or alkyd enamels.
