Trade-quality chalk powder refill supplied in a squeezy bottle for chalk line reels. Suitable for both interior and exterior use, designed for clear, durable marking.
Longer-lasting marks – thanks to trade-quality powder with good adhesion
Powder formulation is designed to adhere to surfaces when snapped from a chalk line reel, reducing dust scatter and loss of pigment. The composition supports consistent transfer from string to substrate.
Lines remain visible for longer, meaning fewer re-marks during a shift. That reduces mistakes and speeds up layout work on site.
High visibility on most materials – with brightly coloured red powder
Strong pigment concentration produces a bold red that contrasts well against timber, plaster and many coloured surfaces. Visibility is maintained in both indoor and outdoor lighting conditions.
Cuts and drill lines are easier to follow, helping maintain accuracy for cutting, aligning and assembly. Visibility reduces eye strain when working over long periods.
Quick, low-mess refills – thanks to a handy nozzle-cap squeezy bottle
A 250g bottle includes an easy pouring spout that controls powder flow, simplifying transfer into chalk line reels. The nozzle-cap design keeps powder contained between uses.
Refilling reels on site is faster and neater, with fewer spilt refills to clear up. The bottle size suits multiple top-ups without frequent trips to the van.
