Marking Powder Proline 225 ml Blue

Proline Marking Powder 225 ml Blue is a powdered marking material designed to produce clear, temporary blue lines and spots on a variety of work surfaces. Supplied in a 225 ml container, the powder is compatible with standard chalk markers and handheld applicators and can also be applied manually for short-term layout, cutting guides and spot marking. The formulation creates highly visible contrast on concrete, wood, soil and other construction or landscaping substrates while remaining removable or weatherable depending on surface and conditions.

Advantages

The blue marking powder provides rapid, high-contrast marks that are easy to see on light and dark materials. Its 225 ml packaging is compact for transport and convenient for use on-site with chalk markers or handheld dispensers. The powder performance supports precise layout work, temporary cutting lines and spot identification without permanent alteration of most substrates when used as intended.

How to use

Shake the container before use if applicable and load the powder into a compatible chalk marker or handheld applicator according to the applicator manufacturer’s instructions. For manual application, sprinkle or tap a small amount of powder onto the surface and use a straightedge, string line or stencil to create the desired line or mark. Apply with steady, even motion to achieve continuous marks; for dots or spot marks, deposit powder in short bursts. Allow the marking to settle; avoid applying excessive amounts that could clog applicators.

Usage recommendations

Use the product on dry surfaces for best visibility and temporary adhesion. Test on a small area if removal or colour transfer is a concern. Store the container in a cool, dry place and keep it sealed when not in use to prevent moisture ingress. Follow safety guidance for dust exposure when handling fine powders and avoid inhalation.
