Blackline - Red Permanent Marking Chalk - (Select Size)
Blackline's permanent red chalk uses the same wind- and water-resistant formula as the brand's black chalk, with red pigment for higher visibility on dark surfaces, concrete and low-light job sites.
Stocked in the 8 oz. refill bottle (BL816R) and the 5 lb. bulk bag (BL54R) for high-volume crews.
Features and Common Uses
- Permanent formula infuses into wood and concrete for a line that resists wind, water and foot traffic
- Red pigment for high visibility on dark surfaces and in low light
- Washes off hands and clothing with mild soap and water despite the permanent line
- Available in an 8 oz. refill bottle or a 5 lb. bulk bag
Commonly used for:
- Snapping high-visibility layout lines on dark or weathered lumber
- Concrete and masonry layout lines exposed to weather
- High-volume framing crews needing a bulk refill

Formula claims (waterproof, windproof, permanent-on-porous-surfaces) and the 8 oz. bottle size are as published on Blackline Manufacturing's own site for its Redline chalk. The 5 lb. bulk size (BL54R) is confirmed via chalk distributors rather than Blackline's current site, which currently lists its bulk size as 4 lb. (BL46R) - treat the 5 lb. bag's exact net weight as distributor-reported, not manufacturer-confirmed. Source: Blackline Manufacturing - Official Site.
Frequently Asked Questions
Why choose red over black?
Red shows up better on dark surfaces, concrete, and in low light - black is the more common choice on light-coloured lumber and drywall.
Which size do I need?
The 8 oz. bottle (BL816R) tops up a standard chalk line box. The 5 lb. bag (BL54R) is the bulk option for a crew going through chalk regularly.
Is it really permanent?
Yes on porous surfaces like wood and concrete - the formula infuses into the surface rather than sitting on top. It still washes off hands and clothing with soap and water.
