Stopgap Red Bag
Application

The standard mix can be used up to a maximum thickness of 6 mm in one application, and will spread down to a feathered edge. For best results an overall thickness of at least 3 mm should be maintained. For applications requiring thicknesses over 6 mm, Stopgap graded aggregate is added to the mix.

The underlayment should be sufficiently hard to walk on in about three hours under good drying conditions, and must be dry before laying floorcoverings.

  • On sound, dry, absorbent surfaces of concrete and sand:cement screeds.
  • For interior floor and light wheeled traffic use.
  • In biologically sensitive areas.
