Chalk tracer GEKO G29040 red 115 g - marking chalk for construction and surveying

GEKO G29040 red tracer chalk, 115 g, is a powdered marking chalk formulated for construction, carpentry and surveying tasks. The red pigment produces clear, visible lines on concrete, wood and masonry surfaces. Supplied as a compact 115 g block for manual marking, this chalk is intended for layout work, site measurements and temporary guides where high-contrast marks are required.

Advantages

This tracer chalk offers consistent color intensity and a fine powder texture that transfers evenly to rough and smooth surfaces. The compact block shape is easy to handle and store, reducing breakage and waste. The red pigment increases visibility on light and medium-toned materials and is suitable for quick, temporary markings that do not require permanent adhesion.

Suitable for

• Construction layout and site marking
• Carpentry and joinery measurements
• Surveying stakes and reference lines
• Masonry and concrete alignment
• Temporary guides for cutting and drilling

Key specifications

• Form: compact powdered block
• Color: red pigment for high-contrast markings
• Net weight: 115 g
• Surface compatibility: concrete, wood, masonry and similar materials
• Application method: manual marking by hand or with chalk holder

How to use

Use the block directly for hand marking or place it in a compatible chalk holder if available. Apply firm, even pressure to transfer the powder onto the work surface and draw lines or marks as needed. For more precise lines, use a straightedge or string line as a guide. After marking, inspect visibility and reapply if the pigment appears faint; wipe or brush away excess powder when adjustments are complete.

Usage recommendations

Store the chalk in a dry place and protect it from moisture to maintain consistent transfer. For prolonged outdoor use, consider reapplying marks periodically as exposure to wind or rain can reduce visibility. Use appropriate protective equipment, such as a dust mask and safety glasses, when working in enclosed areas or where powder dispersion is likely.
