Each 12oz Can of Landscape Adhesive Foam will produce approximately 10 litres of foam when fully expanded (e.g. equal to 5 x 2 Litre fizzy drink bottles fully filled).


  • Foam should be applied to clean, dry and dust-free areas for best adhesion.
  • The exapnding foam can be used on porous and non-porous materials such as rock, stone, cement, wood and cloth.
  • Always wear gloves when applying Landscape Foam Adhesive as this is difficult to remove from skin or clothing.
  • The foam can be cut with a sharp knife once cured, if required.
  • Any residual wet adhesive can be easily removed using the optional Foam Cleaner.
  • Applying small stones or shingle to the filler during the expansion process will help to produce a more natural, decorative effect and the stones will adhere to the foam.
  • Landscape Foam can be used for general exterior filling applications such as filling holes in trees and roots to seal out unwanted garden pests.
  • With larger gaps and voids, layers of foam can be built up on top of one another.
  • Once cured, the expanding foam can be painted if needed.

    The product is excellent for sticking stone to stone, which we have found almost impossible.
