Technical Details

M90 is supplied pre-blended in 25 kg bags or plastic containers and requires only the addition of water. The product can be used from 10 mm - 75 mm in one pass, with greater depths possible using the layer-upon-layer method. M90 achieves exceptional bond strength without the use of 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 product's strength gain and alter its performance characteristics.

 

Preparation

• Surfaces should be free from any contamination of oil, grease, paint, etc.

• Remove all loose particles and work on a sound substrate

• Pre-soak the area with clean water prior to application to aid bond

• Remove ponded water before applying the product

 

Mixing

• 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

• 25 kg of product will require approximately 3.0 litres of water

• A stiff consistent mix with no slump should be achieved, ensuring all particles are well wetted

Note: Mix only enough material to apply within 4 minutes. Never remix or add extra water to the product.

 

Placing

• 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 5 mm 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 10 mm 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
