Thermoplastic Formats: Hot-Applied vs Preformed vs Sprayable Compared
Thermoplastic pavement marking comes in three application formats: hot-applied extruded, hot-applied sprayed, and preformed sheet. Hot-applied extruded delivers the thickest 90-125 mil build through a ribbon shoe behind a ride-on melter -- best for long linear runs. Hot-applied sprayed delivers 60-90 mil through a spray gun -- faster and cheaper but thinner. Preformed sheet is precut, propane-torch-applied at 90-125 mil, and the only practical format for symbols, ADA stencils, and crosswalk bars. All three meet AASHTO M249 when sourced from a qualified manufacturer.
Property managers ordering their first thermoplastic job get pricing surprises because the three formats look like the same product on a data sheet but cost very differently to install. A 14,000-square-foot Salem retail center we restriped in 2025 used all three formats on the same job: extruded for 1,400 linear feet of stalls, sprayed for the gore-area diagonals, and preformed for the ADA stencils, fire-lane "FIRE LANE NO PARKING" text, and continental crosswalk bars at the entrance.
Below we break down what each format is, when to spec it, and how to read a thermoplastic quote that combines all three.
What is hot-applied extruded thermoplastic?
Extruded thermoplastic is the highest-build format. Resin is melted to 410-430 degrees F in a ride-on melter and pumped through a 4-inch (or 6-inch, 8-inch) extrusion shoe that drags behind the machine. The shoe lays a precise ribbon of molten resin onto the pavement at 90-125 mil thick. A bead drop-on applicator immediately follows, dropping AASHTO M247 Type I glass beads at 8-12 lb per 100 square feet for retroreflectivity.
When does extruded thermoplastic make sense?
- Long linear runs (parking lot stalls over 200 feet, lane lines, edge lines)
- High-traffic surfaces where the 125 mil build maximizes lifespan
- State DOT spec work where AASHTO M249 plus 125 mil minimum is mandated
- Projects where ride-on melter mobilization is cost-justified by linear-foot volume
The Cojo crew runs a Crown ProMelt 4000 ride-on for jobs with 1,000+ linear feet of straight-run lines.
What is hot-applied sprayed thermoplastic?
Sprayed thermoplastic uses the same resin formulation but applies it through a heated spray gun rather than an extrusion shoe. Build thickness drops to 60-90 mil because spray atomization cannot match extrusion shoe consistency at full 125 mil. Application is faster (typical 50-70 percent more linear feet per crew-hour vs extruded) and equipment mobilization is lower because hand-walk and walk-behind sprayers are common.
When does sprayed thermoplastic make sense?
- Intermittent runs and short stalls where extrusion-shoe setup time eats the schedule
- Gore areas, diagonal hatching, and odd-angle work where shoe-extrusion cannot turn
- Budget-constrained projects where 60-90 mil lifespan (4-6 years) is acceptable vs 125 mil (6-8 years)
- Touch-up work on existing thermoplastic markings where matching extruded build is not required
Sprayed thermoplastic is not approved for state-DOT lane line work in Oregon -- the state QPL requires 125 mil minimum which only extruded delivers.
What is preformed thermoplastic?
Preformed thermoplastic is precut, factory-finished sheet material that arrives on a job already shaped as the symbol, letter, arrow, or crosswalk bar that goes on the pavement. The crew positions the sheet, heats it with a propane torch (or infrared heater) until the underside softens to ~250 degrees F, and rolls or weights it into the pavement to bond.
Build thickness is typically 90-125 mil at the factory cut, matching extruded. Glass beads are factory-intermixed plus a drop-on layer is added during the heat-and-roll application step.
When does preformed thermoplastic make sense?
- ADA International Symbol of Accessibility (the wheelchair stencil)
- Fire-lane "FIRE LANE NO PARKING" text
- EV-charging-stall green frames and EV symbol
- Continental and ladder crosswalk bars
- Stop bars and yield triangles
- School-zone "SCHOOL XING" text
- Any work where cut detail matters (extruded shoe cannot cut letters)
Preformed costs more per square foot of finished marking but eliminates field-stencil layout time and yields cleaner edge detail. A typical preformed ADA stencil installs in 8-12 minutes vs 25-40 minutes to layout, mask, and extrude the same symbol.

Current Market Reality
2026 thermoplastic resin pricing climbed 18-22 percent from 2024, hydrocarbon resin tracks crude oil, and freight surcharges from Asian glass-bead imports push 9 percent more onto bead-line costs. Cojo's Salem and Eugene crews see preformed sheet pricing up the most because the factory-cut SKU lines (Ennis-Flint Premark, Crown Technology PrismaCut) carry the resin lift plus secondary cut and packaging cost. Buyers comparing 2024 quotes against 2026 should expect 15-20 percent price lift on preformed lines.
How do crews choose between formats on one job?
A real Cojo project specification from a 22,000-square-foot Eugene retail center striped in August 2025:
| Marking | Format | Rationale |
|---|---|---|
| 84 standard parking stalls (4-inch white) | Hot-applied extruded | Long linear runs, maximum 125 mil build |
| 6 ADA accessible stall lines (blue) | Hot-applied extruded | Same machine pass as standard stalls |
| 6 ADA aisle hatching (blue diagonals) | Hot-applied sprayed | Diagonal angles unsuitable for shoe extrusion |
| 6 ADA International Symbol stencils | Preformed | Cut detail and color uniformity |
| 2 fire-lane "FIRE LANE NO PARKING" text | Preformed | Letter detail |
| 4 directional arrows | Preformed | Symbol detail |
| 1 continental crosswalk (10 ft x 24 ft) | Preformed | 8 bars at 24-inch wide |
What about extruded vs preformed for long linear runs?
Some specs allow either format for stop bars and crosswalks. Our extruded vs preformed thermoplastic decision walks through the math: preformed wins on jobs with under 200 linear feet of bar work because the per-bar install time beats the extrusion-shoe setup. Above 400 linear feet, extruded wins.
Which format does state DOT spec require?
Oregon DOT QPL on state-funded pavement marking projects typically requires:
- 125 mil minimum hot-applied extruded for lane lines and edge lines
- AASHTO M249 compliance verified by manufacturer data sheet
- AASHTO M247 Type I glass beads at minimum 8 lb per 100 square feet
- Preformed thermoplastic from QPL list for symbols and crosswalks
- Sprayed thermoplastic only on shoulder striping and gore areas, not main lane lines
Private parking lots have more flexibility but most commercial property managers spec extruded to match Oregon DOT durability.
Which format does Cojo recommend for first-time thermoplastic buyers?
For a property manager moving from traffic paint to thermoplastic for the first time, our standard recommendation is mix all three formats. Use extruded for the bulk of the stall lines, sprayed for diagonals and odd-angle work, and preformed for every symbol and stencil. The mix gets you the durability of 125 mil where it matters and the cut-detail of preformed where layout time would otherwise eat the schedule.
