TecTopics: Why Temperature Matters More Than Ever During the Summer Roofing Season

Summer is peak roofing season, bringing tight schedules, extreme rooftop temperatures, and little room for mistakes. Even minor inconsistencies can lead to wasted material, callbacks, and costly delays. One of the biggest factors affecting installation quality is adhesive temperature.

When adhesive falls outside the recommended application range, it can impact:

• Application consistency
• Bond strength
• Cure time
• Long-term system performance

Take the Guesswork Out of Adhesive Application

Carlisle SynTec Systems' Temperature Sensing Gun (TSG) helps crews using Flexible FAST™ Dual Tank Adhesive monitor material temperature in real time. Instead of guessing whether conditions are right, installers can see the adhesive temperature at the gun, helping them:

• Stay within the recommended application range
• Apply adhesive more consistently
• Reduce variability across the roof
• Install with greater confidence

Check out the Product Data Sheet.

Designed to Keep Crews Moving

Beyond temperature monitoring, the TSG is built to improve jobsite productivity with features, including:

• Real-time material temperature indication
• Constant flow control for consistent adhesive beads
• Up to 75% less trigger force than previous models
• Flexible hose with base connection for improved maneuverability
• Updated tip attachment system for faster setup and maintenance

Together, these features help crews spend less time troubleshooting and more time installing.

How-To: Flexible FAST Dual Tank Application with Temperature Sensing Gun (TSG)

Flexible FAST Dual Tank Adhesive consist of a Part A cylinder and a Part B cylinder. Each Part A box contains a 25’ TSG assembly as well as 10 mixing tips, 10 tip extensions, a wrench, and lithium grease. Before use, make sure the material’s temperature is between 70° and 90°F.

Check out the how-to video.

Setup

• Shake each cylinder for 15 to 20 seconds to ensure contents are properly mixed. A properly shaken cylinder will have a “thud” sound when tapped with a metal object. If the cylinder is not properly shaken, you will hear a “ting” sound. This means the cylinder needs to be shaken more.
• Remove the red protective cap.
• Match the red hose to the part A cylinder and the blue hose to the part B. Tighten each hose with a wrench.

Application

• Pull the battery tab to activate the temperature sensors in the gun.
• Each LED light has a graphic above it.
• Blue = material is below 70°F
• Green = material is between 70° and 90°F
• Red = material is above 90°F
• The green self-engaging safety is in the rear trigger of the dispensing gun.
• To disengage the safety, apply pressure to the green tab while beginning to push the trigger.
• On the rear of the gun below the LED lights is an indicator to show how far the trigger is being applied.
• During the initial use of the tank, apply the trigger to the “start” position. As the adhesive is used, you can increase to the “¾” position.
• Apply the supplied lithium grease to the O-ring and the face of the gun. This will help the tip seal and prevent material from sticking to the gun.
• Open the part A and part B cylinder valves all the way. Adhesive will enter the hose and push the air toward the gun.
• Gently apply the trigger without a tip to purge the air from the hose into a trashcan. Ensure that there are two even streams of material to obtain a 1:1 ratio.
• Clean the face of the gun, reapply grease, and install a mixing tip by placing a tip on the end of the gun, rotating 1/3 of the way.
• When applying Flexible FAST Dual Tank Adhesive as a bead, install a mixing tip and tip extension. Apply the trigger to the “start” position or halfway.
• When applying Flexible FAST Dual Tank Adhesive as a splatter application, use the mixing tip ONLY. Adhesive should be dispersed using a horizontal back and forth motion, achieving 50% coverage of the substrate.

Protect Your Productivity

During the busiest months of the year, every wasted minute and every wasted ounce of material affect your bottom line. By helping crews monitor adhesive temperature and improve application consistency, the Temperature Sensing Gun helps reduce variability, minimize waste, and keep projects moving. It's another way Carlisle SynTec Systems helps contractors work more efficiently during peak roofing season.
