Sealant Types
Butyl Rubber Tape:
This tape is used on aluminum roofs seal seams at the front, rear and down the center. The sealant is available
as a peel and stick waterproof membrane that contains UV inhibitors and is temperature resistant providing
superior seal protection in all types of weather. Store sealant out of direct sunlight between 50º F and 90º F.
To Apply:
1. Clean the aluminum surface with denatured alcohol.
2. Set the tape upon desired area, heat to a warm temperature
allowing tape to form into place.
3. Use a squeegee to mold sealant into cracks and seams, followed by
a roller to roll out tape to get a good uniform seal.
NOTE:
Check the tape at least twice a year for cracks. Use a plastic
putty stick to remove tape. Thoroughly clean the surface
using 3M adhesive cleaner before applying new tape.
Acrylic Foam Tape:
Read the following instructions to properly install the 3M Acrylic foam tape.
• Clean Surface - Use Pro-Clean to clean the surface of dirt, wax, and any other foreign substances for the
best results.
• Surface Temperature - The surface where the product is desired should be 75 °F/24°C for proper
adhesion.
• Adhesion Promoter - Just prior to installation, apply a light coat of Pro-Bond adhesion. The Pro-Bond
will make for a better bond for the Acrylic Tape.
NOTE:
Use a heat gun to warm the product. When storing the motorhome, store in a warm area if
possible. To install acrylic foam tape, cut the liner for the proper length and then peel back
the poly liner from the tape. Apply the tape on the desired line. Continue this process until
the project is complete.
Dolphin Sealants (7549):
Used where items are sealed under a painted surface such as the metal corners of the slide-out room. The
material is specially formulated to allow paint adhesion.
Black Urethane:
Used for sealing the windshields, not to fi ll holes or other imperfections. Black urethane comes in a tube and it
applies much the same way as silicone. Clean up using solvents such as paint thinner. Gloves are required as this
material is hazardous.
