OVERVIEW

Markal BL Paintstik: The Marker That Works Through Primer

The Markal BL Paintstik Solid Paint Marker in Blue (SKU: 80725) is a specialized industrial marking tool engineered specifically for the structural steel and metal fabrication industries. Unlike standard paint markers that are covered and obscured by subsequent coatings, the BL Paintstik features a unique chemical formulation that allows the mark to "bleed through" or migrate to the surface of solvent-based and oil-based primers. This capability is critical in fabrication workflows where steel beams, plates, and parts are marked with identification numbers or layout lines before being sent to the paint shop.

By using the Markal BL Paintstik, fabricators eliminate the time-consuming and error-prone process of re-marking parts after the primer coat has been applied. The mark remains clearly visible on top of the primer, ensuring seamless tracking of assemblies and reducing lost parts during construction. This marker is designed to perform in harsh industrial environments, easily writing on surfaces that are rough, rusty, oily, or wet. It functions effectively in a wide temperature range from -50°F to 150°F (-46°C to 66°C), making it suitable for outdoor yards and unheated workshops.

The solid paint stick form factor provides the durability of a crayon with the longevity and visibility of paint. It requires no pumping or shaking and dries to a permanent, weather-resistant finish. For optimal results, the marker is compatible with standard Markal holders, keeping the user's hands clean and allowing for full utilization of the stick. Whether used in bridge fabrication, ship building, or general structural steel erection, the Markal BL Paintstik is the professional's choice for maintaining traceability through the painting process.

FAQ

The Markal BL Paintstik is designed specifically to bleed through solvent-based and oil-based primers. It may not bleed through water-based primers, epoxies, or powder coats effectively. We recommend testing on a scrap piece first.

It is ideal for steel and iron, including surfaces that are oily, wet, rusty, rough, or smooth.

While not strictly required, using a Markal holder (like the Peterson holder) is highly recommended to keep your hands clean, prevent the stick from breaking, and allow you to use the entire marker.

Yes, the Markal BL Paintstik creates a permanent paint mark that is weather and UV resistant.

The marking range is -50°F to 150°F (-46°C to 66°C), making it suitable for extreme cold and general shop temperatures.

The bleed-through effect typically happens as the primer cures. The solvents in the primer react with the marker, drawing the pigment to the surface.

Yes, it marks well on aluminum, though its primary application is on ferrous metals that require priming to prevent rust.

No. The standard 'B' Paintstik is an all-purpose marker. The 'BL' Paintstik is specifically formulated for the bleed-through property. If you don't need it to bleed through paint, the standard B Paintstik is sufficient.
