CAV-GRIP 3V vs. Traditional Bonding Adhesive
Read This Post
With the introduction of Versico’s CAV-GRIP™ 3V Adhesive, it’s faster than ever to install fully adhered TPO and EPDM. CAV-GRIP 3V 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 3V:
Use larger cylinders and hose splitters: CAV-GRIP 3V comes in two sizes -- 85lb. and 40lb. cylinders. Using 85lb. cylinders allows for more coverage without having to change tanks. By using a hose splitter, two people can spray CAV-GRIP 3V from one tank at the same time, allowing for faster application.
Keep cylinders warm in cold weather: As CAV-GRIP 3V 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°Fbefore use. It is also 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 3V 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 3V to adhere membranes to walls, it is important to overlap 50% when spraying.
Use CAV-GRIP 3V and these tips to save a ton of time and labor on the roof. Time previously used to be spent stirring, rolling, and waiting for adhesive to flash off can now be spent laying more squares of roof to get on to the next job more quickly.
