Construction Oil Marker Expert+ MN-88-081, red, 2.5 mm tip, 10 ml

Expert+ construction oil marker MN-88-081 is a red, oil-based marking pen with a 2.5 mm chisel tip and 10 ml ink capacity. It is designed to create clear, durable lines on a variety of rough and non-porous surfaces commonly encountered on construction sites and in industrial environments, including metal, wood and concrete. The marker delivers consistent pigment flow for visible layout lines, measurements and part identification even in outdoor conditions.

Advantages

The oil-based formulation provides high resistance to water and smudging once dry, ensuring markings remain legible during handling and light exposure. The 2.5 mm tip produces bold, consistent strokes suitable for both freehand marking and measurement lines. Its compact barrel and cap secure closure reduce drying risk and support easy transport in a tool belt or pocket.

Suitable for

• Marking metal sheets and pipes
• Writing on wooden boards and framing
• Layout and measurements on concrete and masonry
• Identification of parts and components on site
• Temporary markings for cutting and welding operations

How to use

Shake the marker well before use to ensure homogeneous pigment flow. Press the tip briefly on a scrap surface to activate the ink and test stroke width. Apply steady pressure for even lines; use the chisel edge for wider strokes and the tip point for finer marks. After use, replace the cap securely to prevent drying.

Usage recommendations

For best results on dusty or oily substrates, clean and dry the surface before marking. Allow ink to dry fully before subjecting markings to abrasion or moisture. Store horizontally in a cool, dry place away from direct heat to maintain ink performance.
