M60: Rapid Strength Bedding Mortar (Pallet Offer 56x 25Kg Bags)

UltraCrete M60 from highly awarded manufacturer Instarmac Group, is the contractors favourite rapid strength mortar because it strikes the balance of having enough workability, a fast set time, rapid compressive strength gain of 24N/mm² in 1hour, it sets in just 20 minutes and can be opened to traffic in 60 minutes. This all purpose fast set mortar is ideal for use with ironwork, access covers, as well as for the rapid bonding of granite setts and flags. M60 is also loved for us on emergency repairs, bedding of kerbs and tidal repair projects. Ultracrete M60 was HAPAS approved in 2005 and conforms to HD27/15.

  • Workability: 5 – 10 minutes
  • Set time: 20 minutes
  • Depth: 10mm – 75mm
  • 24N/mm² compressive strength in 1hour
  • Shrinkage compensated
  • Approved for use on the London Underground and Overground
  • NBS Plus registered for ease of specification
  • Pallet Offer 56x 25Kg reinforced paper bags (25kg buckets available)

Technical information

  • M60 comes pre-blended in a 25kg reinforced paper bag and simply requires the addition of water.
  • The rapid strength mortar can be used at depths from 10mm-75mm in one pass, with greater depths possible using a layer-upon-layer method.
  • M60 achieves exceptional bond strength quickly without the use of an additional primer.
  • M60 mortar can be mixed with a forced action mixer or alternatively by hand with an appropriate tool. We recommend that if you decide to use the hand mixing method, you ensure that it is vigorous and all powder is mixed well.
  • It is possible to bulk out M60 with the addition of up to 30% hard stone clean aggregate, but please note this will reduce the product’s strength gain and alter its performance characteristics. If additional aggregate is added please try a patch test prior to the full repair to ensure you are happy with the final result.

If you'd like any further information, or require a technical or safety data sheet please do not hesitate to get in touch, we'll be happy to provide them. Just give us a call on 0845 862 1099.

How to prepare surfaces for M60 Bedding Mortar

  1. All surfaces should be free from oil, grease, dust or any other visible contaminants.
  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.
  4. Remove ponded water before applying the product.

How to mix M60 Bedding Mortar

  • M60 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 M60 Bedding Mortar

  1. Apply the bedding material over a pre-soaked area.
  2. Once mixed, M60 should be applied to the supporting structure within 4 minutes.
  3. Firm well into position using a float and allowing 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. 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.
  6. Exposed surfaces of the bedding material should be float finished, ensuring voids are filled.
  7. Remove loose materials and point the inside surface to a smooth finish.
  8. Once the bedding material has reached its initial set, the backfill material Ultracrete QC10 concrete can be placed.
