Cold Weather’s Effect on Flexible FAST Dual Tank Adhesives
March 19, 2019
Maintaining the proper storage and installation temperature of Carlisle Flexible FAST roofing adhesive materials will improve the string time/rise time, and will also assist in achieving the proper viscosity of the materials; which in turn will help to increase yield/coverage of your Flexible FAST materials.

Problem:
When working in the states highlighted below, it is important to pay attention to the average daily temperatures when storing and installing Carlisle Flexible FAST adhesives.



Here is a simple explanation of viscosity:

Viscosity is a complicated and sometimes confusing topic, and understanding how to lower viscosity is a challenge during cold winter months. A fluid that is viscous will be thick, sticky, and semifluid in consistency. You can lower viscosity by adding friction and/or increasing temperature. In short, the warmer the material, the thinner the fluid - meaning less friction and increased material flow.



Proper material temperatures can also affect the performance of the adhesive. When material temperatures are below the recommended levels, the adhesive cannot properly mix due to the increased viscosity. It is always important to keep your adhesives stored and applied at the temperatures recommended by the manufacturer.

Carlisle’s Temperature Storage and Application Recommendations
Flexible DASH Bulk and Dual Tank


Do not store Flexible FAST at temperatures above 100°F or below 50°F. Kits stored below 70°F must be given time for the internal material temperature to warm up to 70°F prior to use. When storing or using adhesive in temperatures below 40°F, the adhesive internal temperature must be returned to 70°F prior to use. Placing adhesive in a heated area (70-90°F) for 4 hours should allow liquid adhesive to reach 70-90°F. In colder temperatures, it is recommended to utilize heated blankets to ensure the tanks are kept warm while dispensing the product.

Solution:
In the winter months, proper material temperatures become imperative. Regardless of the urethane adhesive (FAST or Flexible FAST), material temperatures at the time of installation should be 70°F or rising. When temperatures fall below 70°F, urethane adhesives can experience mixture ratio issues. The use of heated blankets or hot boxes should be used to keep material temperatures above 70°F.

Heated blankets make it easy to lower the viscosity of Carlisle’s Flexible Fast Dual Tank adhesives. Heated blankets are available in various ready-to-ship products, including dual tank and single tank adhesive offerings and pallet blankets. If you need help with material storage or viscosity reduction, Carlisle SynTec Systems has you covered. Contact your local Carlisle representative for more information.

Carlisle has partnered with two equipment manufactures that provide heated blankets. For more information, contact 4C’s Spray Equipment. Amped Equipment. or Advanced Roofing Innovations (ARI).

Flexible FAST Frequently Asked Questions

Q: How long will it take a heated blanket to warm a cold tank?
A: Tanks can take anywhere from 4-8 hours to return to the proper application temperature.

Q: Can I use a heated band to warm tank or cylinder products?
A: No -under no circumstances should you use a heated band product with a pressurized tank (Dual Tanks or CAV-GRIP™ III). Heater bands can reach temperatures of 300°F – 400°F, which will overheat the tank and cause it to explode.

Q:Are heated blankets safe to use with Dual Tanks?
A: Yes, heated blankets have a regulated temperature of 80°F - 100°F and are designed to work with pressurized tanks.

Flashing Options for Every Detail

Carlisle offers three different types of Sure-Seal® Pressure-Sensitive (PS) flashings to address the variety of details found on any given roof. All three feature the proven weatherability of EPDM and come with 30-mil of Pressure-Sensitive (PS) SecurTape™ to create a watertight seal. The primary difference among the three is the amount of cure in the rubber, and the process used to manufacture them. PS Elastoform – often called “uncured” flashing – is used to flash irregularly-shaped objects or details with multiple angle changes. The uncured state of the flashing allows the rubber to be formed and stretched into place without reverting to its original shape like cured rubber. The flashing formulation is designed to cure on the roof with exposure to heat. Since it is necessary to limit heat exposure in the manufacturing process; to keep the product uncured; Carlisle requires all edges to be lap sealed. This prevents water from getting between the flashing ply and the tape ply while the material cures on the roof. T-joints, corners, and pockets are all made from Elastoform flashing – which has a 9-month shelf life. PS Overlayment Strip – often called “semi-cured” flashing – utilizes the same Elastoform flashing formulation, but is semi-cured with heat during the manufacturing process. The overlayment strip has the dark black look of uncured flashing, but is 70% cured in order to add tear resistance for stripping in metal edging or end laps. PS Overlayment Strip is packaged without the diamond pattern film, as it is removed during the semi-curing process. This is an easy way to tell the difference between PS Overlayment Strip and a roll of PS Elastoform. Due to the semi-cured nature of PS Overlayment strip, it can seal step-offs at splice intersections of 60-mil rubber without the need for T-joint covers. PS Overlayment Strip is better suited to strip-in seams than PS Elastoform, as it eliminates the need for lap sealant and T-joints. PS Cured Cover Strip is made with the same 60-mil non-reinforced membrane as Carlisle’s standard sheeting, and then laminated to 30-mil of SecurTape. This product is primarily used for stripping-in metal or end-laps and offers the same finished appearance as the field membrane. Due to the fully-cured nature and thickness of the product, T-Joints are required at splice intersections. Carlisle SynTec’s Sure-White® Pressure-Sensitive Flashing is available in Elastoform and cured cover strip options, and is approved for use on both EPDM and TPO roofing systems. Sure-White Elastoform has a more aggressive cure package to account for the fact that the white flashing will not gain as much heat naturally on the roof. This translates into a shorter shelf life of 6 months. Keeping white or black Elastoform flashing cool during long term storage will help to maximize the shelf life. Carlisle SynTec has all your flashing needs covered.

CAV-GRIP III vs. Traditional Bonding Adhesive

With the introduction of Carlisle’s CAV-GRIP™ III Adhesive, it’s faster than ever to install fully-adhered TPO and EPDM. CAV-GRIP III can be used to adhere standard TPO and EPDM membranes in weather conditions down to 25°F, with a much faster application rate and flash-off time than traditional bonding adhesive. Check out this time trial video for proof, and use the tips below to ensure maximum speed and efficiency. Here are some keys to saving time and getting a the most out of CAV-GRIP III: Use larger cylinders and hose splitters: CAV-GRIP III comes in two sizes, 85lb. and 40lb. cylinders. Using 85lb. cylinders allows for more coverage from each tank without having to change tanks. By using a hose splitter, two people can spray CAV-GRIP III from one tank at the same time, allowing for faster application. Keep cylinders warm in cold weather: As CAV-GRIP III cylinders get cold, the coverage rate will be reduced and application will become more difficult. Store cylinders inside or in a hot-box at 70-80° before use. It is important not to set cylinders directly on a metal deck, as this will accelerate heat loss. Instead, always set the cylinder on insulation and use a Power Blanket to keep it warm during application. Overlap is key: When applying CAV-GRIP III to adhere EPDM or TPO in the field of the roof, very little overlap is required. While spraying, try to overlap 1-2 inches to ensure 100% coverage on the back of the sheet and the substrate. However, when using CAV-GRIP III to adhere membranes to walls, it is important to overlap 50% when spraying. Use CAV-GRIP III and these tips to save a ton of time and labor on the roof. The time that used to be spent stirring, rolling, and waiting for adhesive to flash off can be spent laying more squares of roof to get on to the next job more quickly.
