Exceptional Standards for Highways Agency Paint, Double Yellow Lines and Road Line Marking on Every Project
At Promain, we know that painting road surfaces—from white bay markings to box junctions—has a job to do. It's there to keep drivers informed, safe and within the law.
Why Quality Highways Agency Paint Matters for Safety, Road Surface Markings and Longevity
Using the wrong paint on roads or major roads can cause fading, chipping, or loss of visibility—particularly on solid white lines, broken white lines, or lane lines that manage traffic flow. This compromises safety and can breach compliance with national road marking standards.
By using approved highways agency paint, you maintain crisp centre lines, stop lines, and other road surface markings that hold up over time. High-traffic areas like slip roads, cycle lanes, and parking lots rely on paints with high adhesion and resistance to wear—especially from stationary vehicles and changing weather conditions.
Full-Scope Solutions for Painting Double Yellow Lines, Lane Line Systems and Road Line Marking
From painting double white lines on major roads to creating white diagonal stripes in box junctions, our range includes everything you need for reliable road line marking. Whether you’re refreshing mini roundabouts, marking cycle paths, or lining parking spaces in private roads, Promain supplies coating systems suited for all types of road surfaces.
We stock products for every part of the project—line nearest the kerb, solid or broken white lines, and even markings for pedal cycle routes or waiting restrictions. If your job involves high traffic areas, we’ve got the materials to match.
Highway Code Compliance and Highways Agency Approved Road Marking Systems
Our paint systems meet strict highways agency and highway code specifications. From white lines on box junctions to long-term chlorinated rubber coatings on light columns and steel structures, each product is selected to pass relevant performance and durability standards.
This includes paint for solid white lines, double yellow lines, single yellow lines, and stop lines, which all carry specific meanings under the highway code. Ensuring compliance isn’t just good practice—it’s the law, especially in areas under police control or where restrictions apply on bank holidays and weekends.
High-Performance Paints and Coatings for Other Road Markings and Surface Types
We offer paints designed for all common road marking needs, including textured chlorinated rubber paints, high-build systems for line marking, and reflective coatings for cycle lanes and other road markings. Whether you’re painting white lines on concrete, asphalt, or a side road, the materials we supply are chosen for endurance.
Brands like Axalta Bondon 115 and Jotun Jotamastic SF are trusted in structural applications, while our line-painting options are ideal for clear, high-visibility markings—whether applied with a brush or spray machine.
For structural repairs, we also recommend Fosroc Conbextra TS, a reliable choice where heavy-duty precision is required.
Best Practice for Applying Highways Agency Paint to Road Lines and Traffic Lanes
Proper preparation is essential before applying any road line marking. This means ensuring clean, dry surfaces with no oil, dust, or loose debris. Temperature and weather conditions also affect adhesion and curing—important when applying solid lines, broken lines, or bright colours near a mini roundabout or box junction.
Paint thickness, coverage and line direction must all follow the rules set out in the highway code. Whether marking a lane line, double yellow lines, or edges of a parking lot, our technical team is available to advise on how to get it done right first time.
Integrated Road Marking Solutions Including Box Junctions, Cycle Paths and More
Modern road markings don’t stand alone. Many are combined with reflective beads, thermoplastic tape, and pre-treatment primers—especially for slip roads, cycle lanes, and mini roundabouts. These systems help reinforce visibility and durability, especially under stationary vehicles or in adverse weather conditions.
Whether you're installing new white lines, repainting a box junction, or restoring waiting restrictions, we provide the paint and systems to ensure all components work together.
Supporting Major Road Projects and Ongoing Road Line Maintenance
We support contractors, councils, and maintenance firms working across everything from double white lines on trunk roads to road markings for parking lots and pedestrian crossings. Whether it's new build or remedial work, we help streamline the process from quote to delivery.
We understand the complexity involved in coordinating road painting schedules with road maintenance vehicles, weather windows, and legal requirements for traffic control and nearby signs. Our job is to keep your site supplied, compliant and productive.

Frequently Asked Questions
Q: What kind of paint is used to mark roads?
A: Most road markings use high-performance line marking paint or thermoplastic materials. These paints are built for visibility, skid resistance and durability under constant traffic flow, weather and cleaning.
Q: Can I paint over existing road lines?
A: Yes—but proper preparation is key. The old road line must be clean, stable, and well-bonded to the surface. If it’s flaking or uneven, you may need to remove or sand it down before applying new markings.
Q: What paint is used for zebra crossings or box junctions?
A: Typically, bright colour paints with high reflectivity are used. Thermoplastics or highways agency paint with added anti-slip features are ideal for pedestrian areas, crossings, and box junctions with high wear.
Q: Where can I find highway specifications for paint systems?
A: Refer to the Manual of Contract Documents for Highway Works – Series 1900, which sets out required standards for road marking, surface prep, and application, including thickness and material specs.
