Pro+ Black Waterfall Foam, 24 oz, for Use with Foam Applicator Gun

EasyPro Pro+ Black Waterfall Foam is a high-density, minimal-expanding foam designed to seal voids between rocks in waterfalls and streams, preventing water from being lost beneath or around the stone rather than flowing over it. The 24 oz can attaches to the EasyPro PFG Pro+ Foam Spray Gun for controlled, professional-grade application. Black colouring blends into the shadows between rocks and becomes invisible once installed.

Minimal Expansion for Better Control and Less Waste

Unlike standard expanding foam that can overflow and create visible white blobs between rocks, this Pro+ formula expands minimally after application. The result is a denser, better-controlled bead that stays where you put it, fills voids completely, and creates a watertight seal without prying rocks apart or requiring cleanup of overflow. The non-fading carbon black pigment holds its colour permanently, and the fish-safe, non-toxic formula is safe once fully cured. Requires the PFG Pro+ Foam Spray Gun (sold separately).

How to Use

Attach the 24 oz can to the PFG foam spray gun. Apply foam into gaps and voids between rocks while rocks are still dry. Work from the bottom of the waterfall upward. Allow 15 to 30 minutes for initial set before wetting. Trim any visible excess with a knife after full cure (approximately 4 hours). Do not expose pond water to uncured foam. Safe for koi and aquatic life once fully cured and washed with clean water.

Ideal for new waterfall and stream construction, rock resetting, and sealing water-losing areas in existing features where water is bypassing the intended flow path.
