  • Exceptional adhesion to wood, drywall, metal, masonry, glass, and most plastics.
  • Interior or exterior use.
  • Tack free in 6 minutes; trims in 30 minutes.
  • Foam elasticity allows for movement/shifting within a structure from winter to summer.
  • Paintable, stainable, and sandable.
  • Cream colored foam.
