FAQs

Common questions answered.

Five of the questions we hear most often on carpark and street linemarking gear. Full knowledge base on our FAQ page.

  • What is a thermoplastic applicator?

    A thermoplastic applicator is a heated machine that melts thermoplastic material at 180-210 degrees Celsius and extrudes it through a screed box or die onto the pavement, where it cools and fuses to the surface. Thermoplastic lasts 3-8 years on bitumen, accepts intermix glass beads for retroreflectivity, and meets ATS 4110 5.9 (AS 4049.2 / APAS 0041/4) for longitudinal markings. The applicator carries a propane heat source (typically 100,000 BTU on a ProMelt) and a hand-controlled extrusion mechanism.

  • ProMelt or screed box?

    ProMelt for production line runs. Graco ThermoLazer ProMelt 4 inch SmartDie II (24H623) handles long-line thermoplastic with 4-chamber melting and 4-torch die heat. Optional LineDriver attachment converts it to a ride-on for lone-line applications. Screed box for hand-applied work: piano-key crossings, give-way bars, arrows, numerals, council priority lines. The GO Thermoplastic Screed Box Applicator (GOSCB100/150/200/300 widths) carries a 2.5-7 L heated container and dispenses thermoplastic by hand-pull at the chosen width.

  • Do I need an Australian gas certificate to operate this unit?

    Yes. To operate a thermoplastic applicator on public roads legally, the unit needs a gas certificate that complies with the gas-safety legislation in your state. Each state and territory runs its own gas-safety regime, so the documentation, inspection regime, and certifying authority differ between QLD, NSW, VIC, SA, WA, TAS, NT and ACT. Refer to your local legislation, or talk to GO Industrial. We can help coordinate the certification and provide the additional works needed to get your ThermoLazer gas-compliant for the state you are operating in.

  • Can I run thermoplastic on concrete?

    Only after surface preparation. New rigid concrete needs the curing compound removed by grinding or sandblasting per ATS 4110 8.4 before any pavement marking material is applied. Sealed concrete usually accepts a primer pass followed by thermoplastic. Rough or unsealed concrete may need a thicker primer or a different coating system (cold applied plastic / MMA tolerates concrete better than hot thermoplastic). For airport runway and taxiway concrete work, talk to us about the appropriate primer system before quoting.

  • Do I need glass beads in thermoplastic?

    For ATS 4110 longitudinal markings, yes. Type C-HR beads must be intermixed at not less than 30% by mass into the thermoplastic before application (ATS 4110 8.22), and surface-applied beads are added immediately after extrusion. Combined intermix and surface application achieves the required dry retroreflectivity (350 mcd/m²/lx for white longitudinal markings within first 30 days, dropping to 200 mcd/m²/lx between 365-395 days, intervention required below 150). For private property work (sports field, depot, airport apron), bead requirements are project-specific.

Choosing the Right Thermoplastic Applicator

Thermoplastic applies hot at 180-210 degrees Celsius. The melted material fuses to the pavement on cooling, lasts 3-8 years on bitumen, and meets AS 4049.2 / APAS 0041/4 for ATS 4110 longitudinal markings. The right applicator depends on whether you are doing line runs, hand-applied symbols, or audio-tactile work.

Long-line thermoplastic. The Graco ThermoLazer ProMelt 4 inch SmartDie II (24H623) is the production thermoplastic line striper: 4-chamber melting, 100,000 BTU heat, 4-torch die heat, Ease-Z-Steer handle, 156.5 kg, optional die widths up to 16-18 inch, optional LineDriver attachment for ride-on operation. The ThermoLazer ProMelt System SmartDie II (24R771 / 24R767) bundles the ProMelt with system-level accessories. The ThermoLazer 300TC unit (258699 SmartDie II, 24H622 standard) and 200TC unit (17A334 / 17A335 FlexDie, 24U281 standard) cover smaller production volumes and tighter site footprints.

Hand-applied stencils and crossings. The GO Thermoplastic Screed Box Applicator series in widths GOSCB100 (100 mm), GOSCB150 (150 mm), GOSCB200 (200 mm) and GOSCB300 (300 mm) covers hand-applied piano-key crossings, council priority lines, intersection arrows and numerals. 2.5-7 L heated containers, 15-20 kg, application range 180-210 degrees Celsius. Requires operator training. Not for raw concrete unless pre-treated.

Bead intermix for audio-tactile linemarking. ATS 4110 8.22 requires Type C-HR glass beads intermixed at not less than 30% by mass into thermoplastic before application for audio-tactile linemarking (ATLM). Surface-applied beads are added immediately after material extrusion. Audio-tactile rib geometry per ATS 4110 Table 9.2: height 10 plus or minus 2 mm with surface beads, spacing 250 plus or minus 50 mm, width 120-150 mm normal or 150 mm freeway use, length 60 plus or minus 10 mm.

Surface preparation and compliance. Thermoplastic does not adhere to raw concrete without a primer pass. New rigid concrete needs the curing compound removed by grinding or sandblasting per ATS 4110 8.4. Bitumen and asphalt accept thermoplastic directly when clean and dry. ATS 4110 5.9 permits thermoplastic for longitudinal markings provided it complies with AS 4049.2 and carries APAS 0041/4 approval.
