Poor surface prep. The wrong spec. Materials that weren’t suited to the job. These problems show up in the same ways again and again. Most of them were avoidable from the start.
Surface prep. Still the most common cause
It doesn’t matter how good the material is. If you’re laying on polished concrete, diesel bleed or dust, it won’t bond properly. Even when it looks clean, it might not be. Surfaces get overlooked after heavy plant work or signed off before moisture has had a chance to clear. Then the markings lift, flake or trap dirt that kills reflectivity.
Proper adhesion starts before the kettle is even fired up. Miss that step and the failure has already been built in.
Wrong material, wrong site
Thermoplastic is still the default for a lot of teams. It’s fast, familiar and cost-effective. But we see it used in places where it won’t last. Smooth concrete, high-shear junctions, bus corridors with aggressive turning. You’re asking too much from a material that wasn’t designed for those conditions.
Cold plastic MMA lasts longer in those environments. It grips where thermoplastic slips. It holds shape under braking, heat and twisting pressure. It also gives you more control over working time in colder or unpredictable weather. We supply MMA systems designed for those specific situations. Flat, structured or profiled, depending on what the job needs.
Beads that don’t stay put
A line might look right on the day, but if the beads aren’t embedded properly, it will fail retro tests faster than you expect. Poor drop timing, wrong temperature, or a worn gun can cause beads to sit on the surface instead of in the material. Once traffic hits, they’re gone.
In wet weather, standard beads don’t perform well. You need high refractive index beads with moisture resistance if the lines are expected to stay visible when it rains. We make them, but they still get left out of specs until a job fails.
Ghosting that shouldn’t be there
Even when lines are removed properly, ghosting can appear under the right light. That usually comes down to contrast between treated and untreated sections of surface. If the area isn’t retextured or resealed, the original path of the line is still visible in glare or wet conditions.
It’s easy to avoid with a surface seal. But it’s rarely planned in unless someone’s seen it go wrong before.
Mixing systems without checking
We still see paint applied over old thermoplastic. MMA on surfaces that were never cleaned. Line tapes stuck straight onto concrete. Products get blamed for failures when the problem is that they were never supposed to be used that way in the first place.
If you’re working on a site with a mixed substrate or a legacy surface, get in touch. We can help you avoid the usual mistakes before they show up as defects.
The spec is nearly always the problem
If your markings aren’t lasting, there’s a good chance the issue started with the spec. Or the prep. Or an assumption that a standard product would cope in a situation it wasn’t designed for.
We don’t just manufacture these systems. We help contractors, councils and engineers get the right one on the job in the first place. If something isn’t holding up, talk to us. We’ll help you fix it at the root — not just apply another layer on top.
