Each 12oz Can of Touch n Foam will produce approximately 30 litres of foam when fully expanded.


  • The foam is moisture curing so best results are obtained if the area of application is first sprayed with a water bottle.  This will help the foam to expand more and improve the adhesion qualities.
  • Always wear gloves when applying Touch n 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.
  • Touch n Foam Landscape 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.
