Construction Oil Marker Expert+ MN-88-083 — white ink, 2.5 mm tip, 10 ml

Handheld construction oil marker Expert+ MN-88-083 contains white oil-based ink in a 10 ml refillable barrel and a 2.5 mm round felt tip designed for clear, visible marks on concrete, metal, wood and other building materials. The marker delivers opaque, durable lines suitable for layout work, site identification and temporary marking in both indoor and outdoor conditions. The refillable construction supports repeated use and helps maintain consistent ink flow during prolonged jobs.

Advantages

The white oil ink provides high contrast on dark and uneven surfaces and dries to a water-resistant finish that withstands light moisture and handling. A 2.5 mm round tip produces consistently thick lines for easy visibility from a distance while the refillable 10 ml barrel reduces waste and allows the marker to be used across multiple tasks. The marker's robust construction and oil-based formulation ensure marks remain legible on rough or porous materials common at construction sites.

Suitable for

• Marking and layout on concrete floors and walls
• Identification on metal components and pipes
• Timber cutting lines and woodworking layout
• Temporary labels on site equipment and packaging
• Outdoor and indoor construction marking where contrast is required

Key specifications

• Ink type: oil-based, opaque white
• Tip shape and size: round felt tip, 2.5 mm
• Barrel capacity: 10 ml, refillable
• Application surfaces: concrete, metal, wood, masonry and similar materials
• Durability: water-resistant when dry, suitable for temporary outdoor use

How to use

Shake the marker before use to mix the oil-based ink. Prime the tip by pressing it down on scrap material until the ink flows evenly. Apply steady pressure and draw the required marks or lines; the 2.5 mm round tip will produce a uniform, visible stroke. When not in use, replace the cap securely to prevent drying. Refill the barrel using compatible oil-based marker ink following the manufacturer's refill instructions to maintain performance.

Usage recommendations

For best results on very porous or rough surfaces, make a test mark first to confirm opacity and drying time. Store the marker horizontally when storing for extended periods and keep the cap tightly closed between uses. Avoid inhalation of fumes and use in well-ventilated areas; follow local safety guidelines for handling oil-based marking products.
