Product Information
Full details
The Minotaur Builders Chalk is designed for trade professionals and DIY enthusiasts who require highly visible, temporary layout lines on diverse surfaces like brick, grass, dirt, and concrete. Its micro-fine powder formula ensures sharp, bold markings for precision measuring, though users should note that the blue pigment is designed to fade over time and may require re-marking for long-term projects.

FAQs
Can I use this on indoor surfaces?
Yes, but be aware that the pigment is designed to be highly visible and may be difficult to remove from highly porous, unfinished surfaces if it gets wet.
Will this work in a laser-style chalk reel?
No, this powder is specifically intended for traditional manual or automatic string-based chalk reels.
Is the blue chalk permanent?
No, it is formulated to fade over time. The rate of fading depends on weather conditions and surface exposure.
How long will a 250g container last?
Usage depends on the length and frequency of lines snapped, but 250g is generally sufficient for several medium-to-large residential projects.
What should I do if the powder gets on my clothing?
Shake the excess off immediately while dry. Avoid rubbing with water, as this can set the pigment into the fabric fibers.
Troubleshooting
Chalk is clumping inside the reel
Moisture has likely entered the container or reel. Empty the reel, clean it with a dry brush, and ensure you store the chalk in a moisture-free environment.
The line is faint or difficult to see
Ensure the chalk reel line is fully coated by shaking the reel side-to-side before snapping. If the line is still faint, verify the substrate is not excessively wet or oily.
Spout is clogged
Tap the container gently to dislodge powder. If clogged due to moisture, use a thin, dry pin to clear the orifice of the spout.

Setup, Compatibility & Care
To fill your chalk reel, ensure the reel is empty of any old, potentially clumping chalk residue. Open the precision spout on the Minotaur container and carefully pour the required amount into the reel's fill port, holding the container at a slight angle to maintain control. Always secure the airtight cap immediately after use to prevent the powder from absorbing moisture, which can cause clumping and block the pouring spout. Store in a cool, dry place away from direct sunlight to preserve the integrity of the pigment.
