Construction Oil Marker Expert+ MN-88-080, yellow, 2.5 mm tip, 10 ml

Expert+ Construction Oil Marker MN-88-080 in yellow is an oil-based marking tool with a 2.5 mm round tip and 10 ml ink capacity, designed for clear, durable lines on rough and absorbent surfaces. The marker produces high-contrast, weather-resistant marks suitable for measurement, layout and general site marking on materials such as concrete, metal, wood and stone. Its oil-based formula ensures consistent flow and visibility in outdoor and indoor construction, renovation and DIY tasks.

Advantages

This yellow oil marker offers strong adhesion and opacity on rough substrates, delivering visible lines even on dusty or slightly oily surfaces. The 2.5 mm round tip provides a controlled, uniform stroke for both fine layout lines and bolder marks. The compact 10 ml reservoir balances refill intervals with a portable form factor, making the marker convenient to carry on site. The oil-based ink resists fading from weather exposure and remains legible after drying.

Suitable for

• Marking measurement points and cut lines on concrete and masonry
• Identifying metal parts, pipes and structural elements
• Layout and positioning on timber, plywood and composite boards
• Stone and tile marking for cutting or alignment
• General-purpose marking in renovation and DIY projects

How to use

Shake the marker vigorously with the cap on to mix the oil-based ink. Press the tip gently on a scrap surface until the ink flows evenly before marking the working area. For best results on highly absorbent or uneven surfaces, apply steady pressure and redraw lines if necessary. Replace the cap securely after use to prevent drying. Store the marker horizontally at room temperature when not in use.

Usage recommendations

For optimal visibility, test the yellow marker on a small area of the working surface before marking critical layout lines. On very rough or porous materials, allow the ink a few seconds to penetrate and set; for long-term outdoor references, consider complementary permanent marking methods if exposure to heavy abrasion is expected.
