Any loose paint, rust, or grease must be removed through sanding or media blasting. It serves as an excellent anchor for both oil-based and acrylic latex paints, providing flexibility in finishing choices.
Long Term Durability Benefits of Exterior Oil Based Primer
Selecting the correct preparatory coating is the single most important decision when preparing a substrate for a durable finish. Because the drying time is significantly longer than water-based products—often 12 to 24 hours—working in smaller sections is necessary to maintain a wet edge and prevent lap marks.
Advantages Over Water-Based Primers While low-VOC water-based primers are popular for indoor use, they lack the robustness required for harsh outdoor environments. Application Considerations and Drying Times Due to its viscosity and chemical composition, an oil based product requires specific application techniques.
Long Term Durability Benefits of Exterior Oil Based Primer
Surface Preparation is Critical Even the most advanced exterior oil based primer cannot compensate for poor surface preparation. For demanding exterior applications, where the substrate is bare wood, galvanized steel, or masonry, an exterior oil based primer provides the necessary bond, penetration, and protection to ensure the longevity of the paint system.
