The Dow GREAT STUFF™ Pond and Stone Filler, Sealer, and Adhesive is built to help build water features like fountains, waterfalls, ponds, and more.

Build

Dispense in any direction by using the provided straw that will help to direct the foam into the gaps and cracks you want to fill.

Use this in place of GREAT STUFF™ Gaps and Cracks when you need a black foam color.

This foam will bond stone, rock, masonry, concrete, and most building materials together and can be used to fill in any gaps and cracks to help direct the flow of water to go exactly where you want it to go.

The surface of this foam can discolor when exposed to sunlight so it is recommended to cover it if this makes a difference to the appearance of the final finished project.

This foam can be applied to clean, wet or dry surfaces and will last for years in wet conditions which are perfect for ponds, waterfalls, and other water features!

Safety

Wear eye protection, gloves and protect the area from the excess product.

Uncured foam can be cleaned with acetone or GREAT STUFF PRO Cleaner for best results! Cured foam on hands or surfaces must be removed mechanically or allowed to wear off.

Keep ignition sources away from this foam and use them in well-ventilated areas.

How to Use

• Shake can vigorously for at least 30 seconds
