Line Marking Paint

Choosing the Right Line Marking Paint for the Surface and Job

Line marking paint provides a practical way to create visible lines and identification marks across indoor and outdoor areas. Our 750ml aerosol line marker paint range includes red, white and yellow options for marking concrete, tarmacadam, gravel, grass and wood composites. The surface condition, location and expected traffic should be considered before application because they can affect the appearance and longevity of the finished marking. The semi-permanent formulation can remain visible for approximately three months, making it suitable for areas where markings may need to be refreshed periodically.

Preparing Concrete, Tarmac, Gravel & Grass Before Line Marking

Correct preparation helps marking spray paint adhere more consistently and produce a clearer finished line. Preparation should match the type and condition of the surface being marked.

Concrete & Tarmac

• Clean thoroughly – Remove dust, loose material, grease and other contaminants before spraying.
• Allow to dry – Avoid applying floor marking paint to visibly wet surfaces.
• Repair damaged areas – Repair potholes or broken sections before applying the line marking paint.
• Create a stable surface – Sweep away loose stones and debris that could disrupt the spray pattern.

For localised repairs to driveways and pathways, Drive Repair Macadam 23kg can be used to repair suitable damaged areas before marking.

Gravel & Grass

• Remove loose debris – Clear leaves, excessive loose material and other obstructions from the intended line.
• Keep the area dry – Apply when the surface is as dry as practical.
• Allow for movement – Gravel can shift after application and reduce the definition of the finished line.
• Expect natural changes – Grass growth, cutting and weather exposure can gradually alter marked areas.

Where gravel areas require topping up before line marking, 10mm Shingle Mini Bag is suitable for driveway and pathway applications.

Applying Line Marking Spray Paint: Coverage, Drying Time & Application

Before applying line marking spray paint, measure or estimate the total length of the required markings so enough paint can be allowed for the job. One 750ml aerosol can produce approximately 60–100 metres of a 50mm-wide line, depending on the application rate and surface.

Shake the aerosol for at least one minute after the agitator balls begin to rattle, then continue shaking periodically during use. A compatible applicator can provide greater control when using line marker spray paint for longer or straighter runs, while additional care should be taken in windy conditions to reduce overspray.

For best drying performance, apply at temperatures above +10°C. The paint is normally touch dry after approximately 30 minutes, but allow at least two hours before exposing the marking to traffic. Temperature and moisture within the substrate can increase drying times, so confirm that the paint has dried sufficiently before reopening the area.

On suitable concrete floors, floor marking paint can be used to identify routes, boundaries and designated areas. The products can also be used as car park line marking paint for visible bays and traffic guidance where a semi-permanent aerosol marking solution is appropriate.

Get Cleaner, Straighter Lines with the Right Tools & Accessories

Setting out the marking route before spraying and preparing the surface properly can make a noticeable difference to the finished result. Supporting tools and preparation products can also make longer or more detailed marking jobs easier to control.

• Tapes – Help guide straight edges or protect adjoining areas where suitable masking is required.
• Brooms & brushes – Remove dust, stones and loose debris before applying line marking paint.
• Cleaning products – Help prepare suitable contaminated surfaces before marking.
• Protective equipment – Helps manage the working area during preparation and application.
