Features & Benefits
M4 & M12 Mortars
Both our M4 and M12 bagged mortars are suitable for brick laying, block laying, repointing, general masonry repairs and for laying patio and paving slabs. They are available as both natural and a wide range of colours.
To overcome any potential segregation that may occur during transit, the contents of each bag should be mixed before use. The material can be mixed mechanically in a free fall mixer for 3-4 minutes or hand mixed by placing an amount of the dry powder onto a clean, flat surface and slowly adding clean water in increments and mixing continuously with a shovel until the desired workability is achieved. For masonry units that have a high absorption and/or where high ambient temperatures are expected, rapid moisture loss from the mortar can be prevented by pre-wetting the masonry units.
For optimum results, approximately 3.5 to 4 litres of clean water should be used per 25kg bag and each mix of mortar should be used within 120 minutes, after this time it should be discarded. Refrain from excessive water addition, as this will weaken the mix, delay setting times and adversely affect durability. There is no need to add further additives or admixtures to the material on site as all required plasticisers/workability aids are already incorporated into the mix.
The finished mortar should be protected against the effects of the prevailing weather conditions such as, frost, rain and when conditions are dry and/or windy rapid moisture loss should be avoided by covering with plastic sheeting or damp hessian.
Each 25kg bag of CEMEX M4 & M12 Natural Mortar will yield approximately 12 litres of fresh mortar, sufficient to lay approximately 20 standard house bricks or 12 100mm blocks laid with a uniform 10mm joint.
Ordering couldn’t be simpler through our dedicated mortar and sales support teams, locally based and committed to serving your needs.
Bags can be delivered in bulk (nominally 1 tonne) or 25kg bags to site. A forced action mixer will be required to get the correct consistency. Bulk and 25kg bags are suitable for smaller sites or making good where the volume required on site doesn’t lend itself to a silo.
