Ultracrete M90 All Purpose Fast Set Mortar

Ultracrete M90 is a general purpose fast setting mortar that is ideal for bedding ironwork, all access covers and carrying out general repairs. M90 mortar is suitable for use on all ironwork conforming to BS EN 124. The fast set, high strength mortar conforms to HD27/04, and because of its rapid strength gain repairs and works carried out can be opened to traffic in just 90 minutes, saving time, budget and preventing disruption to the general public and motorists.

  • Workability: 5 – 10 minutes
  • Set time: 20 minutes
  • Depth: 10mm – 75mm
  • 21N/mm² compressive strength in 2 hours
  • Approved for use on the London Underground and Overground
  • Sizes: 25kg bag or bucket

Technical information

  • M90 is supplied pre-blended in 25kg reinforced paper bags or plastic containers
  • The mortar only requires the addition of water to create a superior strength mortar.
  • Simply mix on site with a forced action mixer or by hand with an appropriate tool.
  • Use from 10mm-75mm in one pass, with greater depths possible using a layer-upon-layer method.
  • Exceptional bond strength without the need for a primer.
  • The product can be bulked out with the addition of up to 30% hard stone clean aggregate. Please note that this will reduce the products strength gain and alter its performance characteristics (we always recommend testing a small patch prior to full application when adding additional aggregate).

For further details please request the technical data sheet which we'll gladly supply.

How to prepare surfaces for M90

  1. Surfaces should be free from any contamination of oil, grease, paint, etc.
  2. Remove all loose particles and work on a sound substrate.
  3. Pre-soak the area with clean water prior to application to aid bond. Remove ponded water before applying the product.

How to mix M90 All Purpose Fast Set Mortar

  • M90 can be mixed with a forced action mixer or by hand with an appropriate tool.
  • If hand mixing is used, ensure that it is vigorous.
  • 25kg of product will require approximately 3 litres of water.
  • A stiff consistent mix with no slump should be achieved, ensuring all particles are well wetted.
  • Mix only enough material to apply within 4 minutes.
  • Never remix or add extra water.

How to apply M90 Fast Set Mortar

  1. Apply the bedding material over a pre-soaked area.
  2. Once mixed, M90 should be applied to the supporting structure within 4 minutes.
  3. Firm well into position using a float and allow a 5mm excess thickness.
  4. Place the frame onto the bedding mortar ensuring it is fully supported. Check that the frame does not overhang the mortar at any point (use suitable lifting equipment when positioning the frame). Care must be taken to prevent voids in the bedding material under the frame, especially in the cover seating area.
  5. The frame should then be tamped into place ensuring the correct level is obtained.
  6. Any holes within the frame should be in-filled and the flanges of the frame enveloped by a minimum thickness of 10mm of the bedding material.
  7. Exposed surfaces of the bedding material should be float finished, ensuring voids are filled.
  8. Remove loose materials and point the inside surface to a smooth finish.
  9. Once the bedding material has reached its initial set, the backfill material can be placed.
