Rainier Asphalt & Concrete, a Seattle WA, Puget Sound Thermoplasty contractor

Some streets and parking lots are so heavily traveled that it becomes impractical to use traditional traffic paint for pavement markings because they will fade too quickly. It can be burdensome to shut down parking areas or thoroughfares to apply pavement markings, so this product serves as a longer-life solution to paint.

Thermoplastic is applied using a heat-bonded application process. It is used on interstate highways and at intersections on public thoroughfares for things such as arrows, HOV markings, stall stripes, and crosswalk bars. This product is expected to have a lifespan of approximately 5-7 times the lifespan of paint.

Paint vs. Thermoplastic Comparison.
We ran into this job done by another contractor a few years back at the Factoria Mall. It’s a mystery why they would have done it this way, but it showcases nicely how the thermoplastic lasts much longer after the paint starts to fade away.

What is Thermoplastic?

Thermoplastic is a preformed polymer pavement marking material, which is adhered to asphalt concrete pavements and Portland cement concrete pavements by means of heat fusion. The markings are designed for straight lines, arrows, symbols, legends, letters and numbers. The material is designed for high urban traffic volumes and severe wear and will not deteriorate due to exposure to sunlight, oil, gasoline, water, salt or pavement oil content.

How much does it cost?

Thermoplastic installations is both material expensive and labor intensive, and should only be considered for what it is designed for – high traffic volume applications.

Why would somebody want to use thermoplastic rather than traditional striping paint?

Thermoplastic is designed for high-traffic applications such as interstates, high-traffic-volume intersections and parking lot drive-lanes.

What are the various thicknesses that thermoplastic comes in?

We can order Thermoplastic in 90 mil and 125 mil thickness

Explain the process of how it is applied.

The pavement surface is pre-heated with a torch for approximately 40 seconds to a temperature of 280-325 degrees Fahrenheit. The thermoplastic material is then placed over the area and heated from above with a torch in a circular motion, starting from the edges and moving inward until the material has fully conformed to the contour of the underlying pavement structure.

What is the traditional lifespan of thermoplastic?

Thermoplastic has a lifespan of approximately 5-7 times that of traditional traffic paint.
