To install the ALS2020002609 you will need the following:
Water Based Adhesive 1 Gallon
or Water Based Adhesive 5 Gallon
Butyl Tape (Size depends on your needs)
Self-Leveling Sealant
You will also need duct tape (2” minimum width), a paint roller or brush, squeegee, utility knife, and heavy-duty stapler.
Optional: porous tape (masking or fiberglass mesh) for smoother seams
Note: do not use silicone, which will not adhere to the membrane, use Lippert-supplied sealants only
