How to Use FP McCann High Strength Bedding Mortar
Preparation:
- FP McCann High Strength Bedding Mortar should be mixed using the correct amount of water by using a mechanical mixing method such as a slow speed drill and paddle or forced action mixer.
- Mix to consistency suitable for the intended application. Typically, a 20kg bag should be mixed with 2.4l -2.8l of water for dry packing applications. Up to 3.3l of water can be used where a more workable mortar is required.
- Mix product for a minimum of 3 minutes until a homogeneous consistency is achieved.
- Ensure mixed mortar is used within 30 minutes of mixing.
- Adding additional water or trying to revive a mix that has begun to go off will greatly reduce performance.
Application:
- When using this product, good site practice should always apply. FP McCann cannot be held responsible where workmanship has failed to meet the relevant European and British Standards.
- Cement based products will take longer to harden and set at lower temperatures, and should not be used below 5°C. Do not use in ground where frost is present or expected overnight.
- When site temperatures are below 10°C allow extra time before removing supports, applying further loads etc.
- Exposure to drying winds and/or strong sunlight may result in rapid drying and cracking.
- All surfaces must be clean and free from all contamination. For best results, surfaces should be mechanically roughened.
- All surfaces should be saturated with clean water but free from standing water.
- Removable spacers and shims should be lightly oiled.
- Apply mixed mortar as a uniform bed before lowering the precast unit into place. Alternatively, the mixed mortar may be rammed into existing gaps using a suitable tool.
- In all cases ensure the mortar is fully compacted and that full bedding is achieved.
- Allow mortar to stiffen before finishing flush with a damp trowel.
- Exposed mortar should be adequately cured with the application of an appropriate curing membrane or covering with damp hessian or polythene.
