Refill Leads Pica 4040SB — Waterproof Colored Inserts for Pencil Card, 3 Blue / 3 Green / 2 White

Pica 4040SB replacement inserts are waterproof colored leads supplied on a pencil card for use with compatible Pica pencils. The set contains three blue, three green and two white inserts formulated to resist moisture and maintain clear, colored marks on a variety of surfaces. These waterproof colored inserts are intended for tasks where visibility and durability of markings matter, such as construction layout, surveying, and outdoor work in damp conditions.

Advantages

Waterproof formulation preserves line legibility in wet environments, preventing washout and fading. The colored leads provide high contrast on many materials, improving visibility of markings on concrete, wood, metal and plastic. Supplied on a pencil card, the inserts are easy to store and replace, ensuring quick changeover when a different color or fresh tip is needed. The compact set includes multiple colors to match common marking needs without requiring multiple pencils.

Suitable for

• Construction site layout and positioning
• Surveying and geodetic marking
• Outdoor maintenance and landscaping tasks
• Marking on damp or wet surfaces
• Color-coded identification of materials or measurements

Key specifications

• Content: 8 colored inserts (3 blue, 3 green, 2 white)
• Finish: waterproof, moisture-resistant lead composition
• Mounting: supplied on a pencil card for easy storage and replacement
• Intended surfaces: concrete, wood, metal, plastic and other common building materials

How to use

Remove a replacement insert from the pencil card and insert it into a compatible Pica pencil following the pencil manufacturer’s instructions. Advance the lead as needed and apply firm, even pressure to make a visible mark. For best results on rough surfaces, use multiple passes rather than excessive pressure to avoid breaking the lead. Replace the insert when the tip becomes worn or the color fades to maintain clear, consistent markings.

Usage recommendations

Store inserts in a dry place to preserve their waterproof properties and handle with care to avoid snapping the leads during replacement. When working on highly porous or extremely wet surfaces, test the mark on a small area first to confirm visibility, and consider using the white inserts for high-contrast marking on dark materials or the blue/green inserts for general-purpose identification.
