Pica-Marker 4070 lead refill 2B Grey, Red, White

Pica-Marker 4070 lead refill 2B Grey, Red, White is a set of summer leads designed for multi-surface marking. The refill pack contains eight leads in three colours—graphite (2B), red and white—supplied in a blister pack. Leads are formulated to be water resistant and remain stable at temperatures up to 70 °C. They are suitable for use on most construction and craft surfaces but are not intended for glassy or glossy substrates.

Advantages

The summer leads offer consistent stroke quality with a soft 2B graphite option for clear, dark lines and coloured leads for contrast on different materials. Water resistance ensures marks remain visible in damp conditions, while thermal stability up to 70 °C reduces the risk of deformation in warm environments. The assortment of grey, red and white leads allows versatile marking on wood, concrete, metal (prepared surfaces) and many other porous or rough surfaces.

Suitable for

• Construction site marking on wood, concrete and masonry
• Carpentry and woodworking layout marks
• Plumbing and HVAC rough layout
• Workshop and metal preparation marking (non-glossy, non-oiled surfaces)
• Crafts and renovation tasks requiring coloured contrast

How to use

Insert the appropriate lead into a compatible Pica-Marker or similarly sized lead holder according to the holder instructions. Advance the lead gently and make test marks on a scrap area to confirm contrast and adhesion. Use graphite (2B) leads for dark, fine lines and red or white leads when higher contrast is required against specific backgrounds. Replace leads as they wear down; ensure the holder is clean and free of debris before inserting a new lead.

Usage recommendations

Store leads in the blister pack or a dry container to protect against moisture and mechanical damage. Avoid marking on highly glossy or glassy surfaces; for such substrates consider using a dedicated marker suitable for non-porous finishes. When working in elevated temperatures, keep packs away from direct heat sources to maintain lead integrity.
