- Mix only enough material to apply within 4 minutes.
- Never remix or add extra water.
How to apply M90 Fast Set Mortar
- Apply the bedding material over a pre-soaked area.
- Once mixed, M90 should be applied to the supporting structure within 4 minutes.
- Firm well into position using a float and allow a 5mm excess thickness.
- 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.
- 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.
- Exposed surfaces of the bedding material should be float finished, ensuring voids are filled.
- Remove loose materials and point the inside surface to a smooth finish.
- Once the bedding material has reached its initial set, the backfill material can be placed.
