Description

A polymer modified, fast setting mortar for repairing external floors prior to the application of Stopgap 850 or for use in internal applications under Stopgap waterproof surface membranes. It has been specifically designed for use in damp conditions and has excellent freeze/ thaw resistance when used in external environments.

It can be used for the non-structural repair of lower strength concrete elements such as floor screeds, concrete paving slabs, balcony edges, stair treads and risers and is also suitable for producing gradients for ramps.

It is dimensionally stable and is supplied as a pre-blended dry powder designed for applications between 3–50 mm. It is protein-free which allows it to be used in biologically sensitive areas, and is suitable for use with sand/ cement screeds, concrete and under Stopgap waterproof surface membranes.

Use Styccoclean C140 for removing grease, oil, polish, soap etc. from non-absorbent substrates.

For filled mix add Stopgap graded aggregate to the standard mix.

Features:

  • Can be used in external applications.
  • Moisture tolerant.
  • Fast setting.
  • Ramps and covings can be formed.
  • Can be used in vertical applications.
  • Low odour.
