FAQs

Helix Adhesive is gray, which is unique in the industry.
The substrate and ambient temperature must be above 32°F when using Helix Adhesive. If temperatures are below 50°F, the adhesive must be kept warm before use.
No. Helix Adhesive is applied in ¾" wide beads or ribbons spaced 4", 6" or 12" on center depending on the conditions of the project.
Mule-Hide will issue a labor and material warranty on qualifying systems. If Mule-Hide has a listing utilizing the Helix Adhesive and the contractor uses a different manufacturer without prior approval from Mule-Hide, a warranty will not be issued.
Helix Adhesive does not stick to new, or previously unexposed, asphalt that has a shiny appearance. Whenever shiny asphalt is encountered, the asphalt must be primed with CAV-GRIP prior to the installation of Helix Adhesive.
Material costs to adhere insulation to a roof deck using Helix Adhesive is much more expensive than using screws. As a general rule, material costs to use Helix Adhesive is around 5 to 6 times more expensive than using screws when one layer of insulation is installed. Unlike mechanically fastening insulation where only the top layer is fastened, each individual layer must be adhered when using Helix Adhesive. However, some of the major benefits to using Helix Adhesive can greatly reduce costs in other areas of the project.
Yes, absolutely! Each manufacturer designs mixing tips to create the desired 1:1 ratio based on the properties of their product. You must use Helix mixing tips when using the Helix Gun Assembly or Cartridges. Failure to use Helix mixing tips results in off-ratio mixing and the Helix Foam will not properly rise.
Only fleece-back membranes can be adhered using Helix Adhesive. Currently, Mule-Hide offers TPO, PVC, and PVC KEE HP in fleece back configurations.
Helix Adhesive has a shelf life of approximately 12 months when stored in an upright position at 50°- 90°F in its original unopened container. Storage temperatures above the recommended range shorten shelf life. Do not store in direct sunlight or temperatures higher than 90°F, such as using it for tarp weight on a roof. Helix Adhesive should be store in a covered, secure location. Keep from freezing. Product stored below 50°F must be given sufficient time (minimum 24 hrs.) for the adhesive to warm up prior to use.
No. PVC is not an approved substrate for Helix Adhesive. In addition, Helix is not approved for attachment to existing EPDM single-ply membranes, acrylic or aluminum coatings.
It is recommended that adhesion tests be done by Mule-Hide. Adhesion tests are scheduled through Mule-Hide Territory Managers.
Helix Adhesive tests are simple "shovel" tests. The existing substrate is prepared in the same manner as the specification and then a piece of the specified insulation is adhered using Helix Adhesive. Once cured, the insulation is pried off of the substrate with a shovel. A positive adhesion test is when the board breaks before the insulation peels off of the substrate. If specific uplift values are required, fully metered and measured pull tests can be performed based on ANSI/SPRI IA-1 Field Test Standards.
Low-rise foam adhesives have performed well for nearly two decades. Over the past two decades, experience in the market has created an industry accepted list of best practices. Mule-Hide recommends adhesion tests on those substrates that have a lengthy history in the market with known characteristics. Mule-Hide requires adhesion tests on substrates that do not have an established history in the market or have critical variables that, if left unaddressed, will adversely affect the bond of Helix Adhesive. As always, good roofing practice dictates that adhesion tests should be done on all projects to ensure a quality bond using foam adhesives, regardless of whether they are recommended or required.
