How to Use FP McCann Thixotropic Pumpable Mortar
Application Guidance
- When using this product, good site practice should always apply. FP McCann cannot be held responsible where workmanship has failed to meet relevant European and British Standards.
- Cement based products will take longer to harden and set at lower temperatures, and should not be used below 5ºC. Do not use in ground where frost is present.
- When site temperatures are below 10ºC consider allowing 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.
- Mixed mortar should be pumped into place using a suitable pump unit. Typically a pump rate of 10-15L/min is suitable.
- Pumping should be continuous until the void is fully filled and mortar is fully compacted.
- 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.
Mixing & Water Guidance
- FP McCann Thixotropic Pumpable Mortar should be mixed using the correct amount of water by using a mechanical mixing method such as using a suitable slow speed high torque drill and mixing paddle or larger amounts mixed in a suitable mixer pump system.
- Mix to a consistency suitable for the intended application. Typically, a 20kg bag should be mixed with 3.6-4.2 of water.
- 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.
