THE FISH-FRIENDLY GAP FILLER

Specifically designed to help quickly and easily build beautiful water features, this polyurethane foam expands to fill gaps and cracks to help direct water to flow over the rocks in a waterfall, rather than under and in between.

Here's what makes GREAT STUFF™ Pond & Stone great:

  • Is black in color to blend in with stones and shadows
  • Bonds without mortar
  • Helps direct water over, not under, rocks
  • Creates a water-shedding bond for stone, rock, masonry, concrete and other building materials
  • Safe for ornamental fish and plants
  • Lasts for years in wet conditions

It's easy to work with because it:

  • All-direction dispensing
  • Can be applied to damp and dry surfaces
  • Cures in 8 hours1
  • Is UL Classified

170 ± 5°F and 50 ± 5 % RH, 1 inch bead diameter, 6 inch length. Cure rate is dependent on temperature, humidity, and size of foam bead.
