Sikaflex® – 715 is a semi self-leveling RV sealant so the goal is to apply a large beadat the seam or profile to be sealed, and let the sealant flow uniformly in both directions. Begin by cutting about 1 inch off the end of the cartridge nozzle. Apply sealant slowly so that the finished bead width is about 1 inch wide over the seam or profile. Screws should be covered with a dollop of sealant. Clean uncured sealant with mineral spirits or other solvent-based cleaners.

Full curing requires 2 to 5 days depending on climate conditions andsealant thickness. The RV can be moved, transported, or driven outdoors, even inrainy conditions, after the skin forms on the sealant.
